[edit] BB Doesn't Address Origin of Universe

I note that the third paragraph of this article makes the following statement:

"...its [the CMB's] discovery led to general acceptance among physicists that the Big Bang is the best model for the origin and evolution of the universe."

It is indeed the best model for the evolution of the universe, but since there is no evidence of the conditions at "t=0", the "big bang model" currently says nothing about the origin of the universe. --64.122.177.153 (talk) 17:20, 17 January 2008 (UTC)Cougar

[edit] first time editor has a question about the Universe

I may have overstepped my boundaries here so someone please help out. I don't know where or how to make a general comment so I am placing it here in hopes that someone who works for Wiki can answer my question. I was perusing the "universe" page and I saw that there was a statement about the Big Bang. Now I believe that the Big Bang actually happened, but there was a subjective viewpoint expressed therein. The statement was something to the effect of, "the beginning of the universe is called the Big Bang." I changed this to say, "the moment God initiated the universe is called the Big Bang, in the scientific community." UH-OH! I should have known that someone would not like that, (RYAN I believe his name was) can he, or anyone else tell me how we can change this to represent an unbiased explanation. I thought mine was ok but knew it was not perfect. —Preceding unsigned comment added by 128.138.64.32 (talk) 23:33, 28 January 2008 (UTC)

Posting anything even remotely in favor of God on Wikipedia is suicide. Now, I'm not atheist or anything, but it is generally accepted that on pages dealing with matters of science, the consensus of the scientific community should be represented. Something like, "The creation of the universe is believed by scientists to be the result of the Big Bang," or, "The Big Bang is believed by scientists to be the cause of the universe." is better. Or you could think of something better. And don't worry about overstepping your boundaries, Wikipedia is all about being bold. Trust me, you will encounter a lot of bold people here. Well, happy editing. I suggest you make an account. Welcome to the team.--Asderoff (talk) 22:11, 30 January 2008 (UTC)
I think the issue was clearer than that. That statement wasn't just "remotely in favor of God". It was claiming as fact that a singular God existed and created the Universe, a point of view that excludes many religions as well as non-believers. And "believed by scientists" in a scientific article is redundant. The various gods that people believe in have their say in the creation myth article, where the Big Bang makes but a brief guest appearance. rspeer / ɹəədsɹ 10:25, 31 January 2008 (UTC)

I already understood that speaking about God is suicide in Wiki. But amazinlgy it is not suicide to mix scientific facts and consensus. You always use that word, consensus, when you should speak about dogmatism. Any different with God concept? —Preceding unsigned comment added by 83.103.38.68 (talk) 14:13, 13 June 2008 (UTC)

[edit] Latest Mod

Thats cool, I was just demonstrating to a friend the fundamental nature of wikipedia, and you were most co-operative. Thankyou:-) —Preceding unsigned comment added by 134.159.111.66 (talk) 06:19, 3 February 2008 (UTC)

[edit] second photo contains incorrect information "http://en.wikipedia.org/wiki/Image:3duniverse.png"

http://en.wikipedia.org/wiki/Image:3duniverse.png


This photo contains text whihch states that the human species has existed for "a few million years". However the wikipedia article on the human species (http://en.wikipedia.org/wiki/Human) states that "DNA evidence indicates that modern humans originated in Africa about 200,000 years ago"

I suggest removing this document.

[edit] Proof the scientest need change the name of this.

The Big Bang, that's impossible. Now, I DON'T argue that there WAS and explosion that created the universe. However, there was NO BANG!!! Ya see it's simple, there is no air in space, thus nothin' for sound waves to travel through, thus no sound, which means that the "Big Bang" never occoured. Yes, they was an explosion but no actual bang. Just proved that scientest don't ALWAYS know best after all. --Crash Underride 18:47, 23 February 2008 (UTC)

There would be no bang if an explosion occurred in space as we know it, i.e. with an average density of 1 hydrogen atom per square meter. However, at the time the universe was a lot denser: denser than usual "terrestrial" materials, denser than star cores, even denser than neutron stars. The higher the density of a material, the faster the speed of sound. So, there was a bang, and it travelled extremely fast from the center of the event to the edge. Devil Master (talk) 16:24, 20 May 2008 (UTC)
It's called the "Big Bang" for the same reason sunset is called "sunset", even though "Earth-turn" would be more accurate. It's the name everyone uses and recognizes. (Anyway, there probably was a bang within the expanding matter.) Art LaPella (talk) 18:44, 24 February 2008 (UTC)

[edit] big bang universe end theory

if the big bang is said to continuesly repeat itself wouldnt that break the whole fact of religion exept for the belief in reincarnation —Preceding unsigned comment added by 203.122.104.28 (talk) 09:47, 27 February 2008 (UTC)

In my opinion, religion (with or without reincarnation) could adapt to an oscillating universe, in the same ways it has adapted to the current scientific consensus. Art LaPella (talk) 22:08, 27 February 2008 (UTC)

[edit] Religion And The Big Bang

Shouldn't There be a section about Religion and the Big Bang. Like how they support, or Contradicts with each other?--Obaidz96 (talk) 23:49, 2 March 2008 (UTC)

[edit] Support
  • There Should Be one, many verses in the Quran say that the Universe/Space is constantly Expanding. And I am pretty sure the bible has some verses tha contradict with the theory. --Obaidz96 (talk) 23:49, 2 March 2008 (UTC)
  • Adding a section like this would be useful in showing these contrasts, and in providing perspective with a different POV. scetoaux (talk) (My contributions.) 23:53, 2 March 2008 (UTC)

[edit] Oppose

[edit] Neutral
  1. There already is one. It's called Big Bang#Philosophical and religious interpretations. It's vague, but it links to a larger, more specific article Philosophical and religious interpretations of the Big Bang theory. Art LaPella (talk) 03:07, 3 March 2008 (UTC)
  2. The sub-section pointed to by Art LaPella is fine and enough imo. --Childhood's End (talk) 14:33, 3 March 2008 (UTC)

[edit] Hoyle

This edit duplicates material about Hoyle in the fourth paragraph of Big Bang#History. Art LaPella (talk) 18:33, 8 March 2008 (UTC)

Agree. I would vote to remove it, although the last sentence is new and could be kept if you think it's relevant. --Childhood's End (talk) 08:51, 9 March 2008 (UTC)

[edit] Criticism

I removed an unsourced bit about criticism from the intro that didn't seem to relate to the existing criticsm section - unless I've mis-interpreted. Also removed the rather overdone Lerner quote - so he's complaining about the "powers that be", so what. If there are other sources that back up his sour-grapism then let's see 'em. Vsmith (talk) 15:28, 9 March 2008 (UTC)

I rephrased the support for Big Bang that looked like criticism to Vsmith and so it was removed by him. Jim (talk) 15:55, 9 March 2008 (UTC)

[edit] Intro Trashed?

I pretty much rewrote the introductory paragraphs, which to me appeared to have been thoroughly trashed by creationists or some such. It was gobbledegook. I haven't done a lot of Wiki editing, and I didn't look into previous versions, but I've done some considerable study on this topic, and the Intro is now intelligible and accurate to my knowledge. Comments, criticisms, and nitpicks welcome. Go ahead and make it better. If you're unsure, ask first. DCCougar (talk) 21:41, 11 March 2008 (UTC)

I have very mixed feelings about your changes to the introduction. Would you mind saying why, specifically, you felt the version you changed was trashed? CKCortez (talk) 23:36, 11 March 2008 (UTC)
Well, the previous version is gone now, so I can't address specific points. (Is the old version available somewhere?) Basically, it contained numerous inaccuracies, it contained side-trips out into areas that are not central to the theory, and Jim's claim about the "most important achievement" (see below) is terribly far off the mark. It was scattered and unintelligible. The theory is simple at its base. I try to inform, not confuse. DCCougar (talk) 13:32, 12 March 2008 (UTC)
Click here for the old version. To find old versions without me, go to the Big Bang article, click the tab that says "history" near the top of the screen, and click one of the time and date stamps. Each represents a different historical version of the page you want - in this case, the version you want is 14:12 March 10, 2008, just below your first (lowest) edit, which is labeled with DCCougar. Art LaPella (talk) 20:48, 12 March 2008 (UTC)
Thanks, Art. A good example of the inaccurate or unintelligible introductory description that I was mortified to find is as follows: "The model is based on a theoretical lack of the Hubble type redshift in a stationary universe and so on a constant creation of the energy necessary to compensate for the dynamical friction of photons in such a universe." I still can't make out what is trying to be said here. The model is based on observational evidence. That evidence pretty much ruled out Hoyle's "eternal" model. Hoyle was one stubborn scientist, though, and like Arp, he scrambled to find some explanation, however unlikely, for the inconsistencies between his model and observation. DCCougar (talk) 15:17, 13 March 2008 (UTC)
I also don't see what was wrong with the previous version - perhaps you can explain what part you felt was 'gobbledegook' or why you felt it was 'trashed by creationists'. PhySusie (talk) 01:22, 12 March 2008 (UTC)
Why have you deleted my edits about the most important achievement of the Big Bang Theory: the invalidation of the principle of conservation of energy and finally allowing for unity of science and spiritual life?
It's new physics, unknown before the Big Bang Theory, when every physicist and his brother thought that "energy can't be created out of nothing". The expanding universe theory showed conclusively that it can be created out of nothing and it is easily created in sufficient amounts. I hope you appreciate the fact that if energy were strictly conserved the expanding universe wouldn't be possible and all the astronomical observations had to be explained also in Einstein's universe (as they are explained with a possibly phony "Einsteinian gravitation" by cranks). Since the fact of creation of energy is taught in all general relativity courses around the world, even if your POV is different, it is not allowed in wikipedia since it goes against the mainstream science. TELL THE WIKITRUTH Jim (talk) 09:50, 12 March 2008 (UTC)
"Mainstream science" does not teach that the Big Bang invalidates the principle of conservation of energy: the Big Bang is regarded as containing all the energy that is now distributed throughout the Universe. Also, I've never seen "the fact of creation of energy" taught in any general relativity tutorial (nor is it presented in the Wikipedia article on GR). And what does "finally allowing for unity of science and spiritual life" mean? --Robert Stevens (talk) 11:31, 12 March 2008 (UTC)
Thank you, Rob Stevens. Yes, Jim, you seem to be in the wrong place. This theory has nothing to do with "unity of science and spiritual life." Please do not attempt to impose your beliefs where they do not belong. DCCougar (talk) 13:33, 12 March 2008 (UTC)
Ah - thank you for catching that - the older version that I looked at didn't have all that. Good catch. PhySusie (talk) 14:45, 12 March 2008 (UTC)
That the Big Bang invalidates the principle of conservation of energy is a common knowledge even if it is not known to the wikipedia editors. It comes from the Noether theorem applied to the expanding universe. You may check it with the university where I'm doing my PhD in general realtivity. The head of "Cosmology and Gravitation" is prof. Demianski (click on "Authorities and people" and slect his e-mail). If he's not enough then prof. Meissner told me that my proof of validity of Einstein's universe has to be rejected on grounds of invalidity of conservation of energy. Otherwise Einstein's idea is fine, and it would explain the illusion of accelerating expansion and even Pioneer anomaly. Its only problem is that the validity of Einstein's universe is based on conservation of energy which according to mainstream science is false. If this principle were true the university could get first Nobel Prize in its history. So you are adding insult to injury by maintainig that "mainstream science" allows conservation of energy. It does not and the result is the Big Bang and invalidity of Einstein's universe.
The "unity of science and spiritual life" is something that theist want to push through, using the Big Bang as a vehicle, since the Big Bang contradicts the conservation of energy. Just yesterday a Catholic theologian, prof. Michael Heller got $1,600,000 prize (biger than Nobel Prize) for cosmology. Supporting guess what. The scientists from U. of Kansas maintain that support of Einstein's universe is an atheist plot. So I just wanted you to be consistent in your belief in possibility of creation of matter from nothing. Jim (talk) 16:13, 13 March 2008 (UTC)
Jim wrote: "That the Big Bang invalidates the principle of conservation of energy is a common knowledge even if it is not known to the wikipedia editors." Please provide peer-reviewed journal articles supporting this position. More to the point, however, explain how this is central to a general understanding of the Big Bang theory. I have no problem with violating the law of conservation of energy -- dark energy, if accurately described by the cosmological constant, does that -- however, I don't see how this is at all central to the theory, and its positioning in the introductory paragraphs can only confuse, rather than inform wiki-readers. DCCougar (talk) 18:32, 13 March 2008 (UTC)
Jim wrote: "The "unity of science and spiritual life" is something that theist want to push through, using the Big Bang as a vehicle, since the Big Bang contradicts the conservation of energy." So why are you even talking about it? DCCougar (talk) 18:34, 13 March 2008 (UTC)
...Huh? Jim, "Einstein's Universe" refers to a static-Universe, steady-state theory which Einstein later considered to be a mistake (his "biggest blunder", in fact). You tried to "prove" that it was valid? Why? And your "proof" failed? How is this relevant to the Big Bang theory? And steady-state theory is NOT "fine", it is contradicted by numerous observations (not just redshift). And Heller was awarded the Templeton Prize, which doesn't mean much in academic circles anyhow: it's a religious prize. But if it was for musings on the Big Bang: so what? According to mainstream science, the Big Bang happened, regardless of whatever "spin" theologians want to put on it. --Robert Stevens (talk) 19:21, 13 March 2008 (UTC)
Also, Jim, you might want to review Wiki's No original research policy. DCCougar (talk) 22:22, 13 March 2008 (UTC)

Hi DCCougar and Robert Stevens. If I wanted to talk about all subjects I'd have to violate No original research policy since those things are the subject of my PhD work and a PhD work by definition is an original research.

While I can't show my original research I can answer your questions. That the conservation of enrgy is not valid in the Big Bang model you may ask any general relativity professor from any university in the world. All of them know that the Big Bang does not allow conservation of energy.

I can also "explain how this is central to a general understanding of the Big Bang theory" in other words "why the Big Bang does not allow conservation of energy?".

The short answer is that conservation of energy implies a redshift in a stationary universe and so if we want to have the expansion of space we have to get rid of conservation of energy since we can't have two reasons for the same effect (then the effect would be twice as big and it's not).

The long answer is that in general any object moving through the universe is a subject to so called dynamical friction. It is on average a loss of kinetic energy of the moving object to the surroundings (if it is gain then it is called sling effect). The effect can be calculated applying the principle of conservation of energy and when surroundings gain the energy the object is assumed to lose the equal amount of energy. When we calculate this loss for photon's energy in a static universe of desity of ours, we get redshift of the same order of magnitude as the Hubble redshift. It looks like a "tired light effect" (the same equation) but we know that in Einstein's gravitation, there is no "tired light effect" since there are no gravitational forces acting at the distance. So this effect can only be either a relativistic effect of time dilation at the source of light (similar time dilation as in gravitational redshift) or the priniciple of conservation of energy is not valid for photons and the redshift is Doppler and so the space is expanding. Since the former would require the time runing slower "simultaneously" at two points in space (which was too radical a physics at that time to admit, even for Einstein, not anymore though since relativity got stronger) the former possibility has been abandoned and invalidation of the principle of conservation of enrgy admitted for the construction of the Big Bang model. So the principle of conservation of energy has been assumed not to be valid for photons and the dynamical friction for photons was assumed to be exactly zero and the reason for the redshift has been assumed to be an expansion of space. That's why it is essential for the model. We don't see any expansion, we just assume it indirectly, assuming that in a static universe there wouldn't be any Hubble type redshift (since the principle of conservation of energy is assumed not to be valid for photons). It might look like a lousy physics but it is cosmologists who accept it not physicists.

The subject of my work is basically that "some physical theories are wiser than their creators" (Hertz). In my work I'm showing the things that Einstein didn't want to argue about with the cosmologists and I'm showing why if the energy is conserved the observations show that the universe is stationary. It's an observational result. No theory except Einstein's.

Einstein was a physicist who had litle appreciation for math ("As far as the laws of mathematics refer to reality, they are not certain, as far as they are certain, they do not refer to reality.") so he didn't want to argue with cosmologists who were applied mathematicians. He already said that the biggest blunder of his life was discovering the cosmological constant which started this madness of each cosmologist subscribing to his pet value while its obvious value was c2 / (4πGρ). Something that after a while made to the urban legend as "Einstein admitting his blunder of discovering cosmological constant". Repeated by many as if discovering anything might be a blunder. He also told his secretary not to let in anybody who wants to talk to him about the universe (source: his associate Roy Glauber, my teacher at Harvard).

So if you are patient and the principle of conservation of energy, which Einstein as a patent office clerk must have understood better than any applied matematician, makes back into the mainstream science you may see all of these things explained successfully by the "mainstream science" in a few years. If you are curious though how Einstein's theory explains things that cosmologists can't explain without inventing new physics (dark energy) and if you are able to assume that the principle of conseation of energy is valid, agree to the fact that the space might be curved and that the time is delated accordingly, luckily all controlled by simpler than Newtonian equations -- and luckily there isn't anything else in Einstein's theory, you will see then how Einstein's theory can explain and predict numerical values of Hubble constant, accelerating expansion, CMBR, Pioneer anomaly, such phenomena as local quasars, all calculated only from the first principles, agreeing with observations up to one standard deviation. At the same time contradicting the priest's science (as Einstein called the Big Bang) that the church supports with awards bigger than the Nobel Prize. Einstein's "crank physics" (so far) is only supported by the principle of conservation of energy. An ungodly principle preventing God from creation universes out of nothing and even preventing the universe from expanding or shrinking and that's why the "mainstream science" had to drop this principle to stay internally consistent. So this fact shouldn't be hidden from the public opinion since this is the only difference between the Einstein's "crank physics" -- with the principle of conservation of energy -- and the priest's science -- without it, but instead with such mighty protectors as Wikipedia and the Catholic Church. Jim (talk) 15:49, 14 March 2008 (UTC)

...Except that it isn't "the only difference". You're essentially claiming that the astronomers are ignorant of the relevant physics, whereas it actually seems that the steady-state advocates are ignorant of the relevant astronomy. Plenty of people over the years have proposed that redshift might be due to causes other than the expansion of the Universe (this isn't exactly some new groundbreaking idea), but all have come unstuck due to the inability to explain the other astronomical evidences of the Big Bang. See Steady state theory. --Robert Stevens (talk) 17:20, 14 March 2008 (UTC)
You are right, it isn't "the only difference". I should say it is the only fundamental difference since most other things in both theories are the same, except that the Big Bang does not produce any verifiable predictions and so it can't be falsified (and in this sense it is not a theory but an unverifiable hypothesis contradicting the standard physics -- the principle of conservation of energy). Einstein's stationary universe on the other hand produces at least five verifiable predictions (that I mentioned earlier) so it can be falsified if it fails just in one of its predictions. The Steady state theory of Hoyle etc. has the same problem as the Big Bang, an unverified so far creation of matter from nothing, so all other problems become irrelevant and it is irrelevant how many things the steady-state advocates are ignorant of.
It would be interesting if you could present those "other astronomical evidences of the Big Bang theory" that Einstein's stationary universe explain falsly (produces wrong numbers) since then Einstein's stationary universe would be falsified. Could you do this? Jim (talk) 20:18, 14 March 2008 (UTC)
Jim wrote: So if you are patient and the principle of conservation of energy... makes [it] back into the mainstream science you may see all of these things explained successfully by the "mainstream science" in a few years.
Until that time, it has no place in this article. DCCougar (talk) 21:09, 14 March 2008 (UTC)
Jim wrote: ...the Big Bang does not produce any verifiable predictions and so it can't be falsified...
With statements like this, I am forced to seriously doubt you are a doctoral candidate, and further discussion is pointless. You do not seem to realize that the big bang theory does not make any claims about times earlier than 10^-19 seconds -- we are unable to simulate conditions earlier than that since our particle accelerators are currently not the size of the solar system. The big bang is a theory about the evolution of the universe after that early time. It says NOTHING about the ultimate origin of the universe. How can it? There is no evidence. Scientific theories are based on evidence! I have recently read current books by leading physicists and cosmologists such as Alex Vilenkin, Paul Steinhardt & Neil Turok, Leonard Susskind, and Lee Smolin. It is interesting that they ALL agree that the big bang theory is essentially correct from 1 second after the "bang" to the present day. Their only disagreements come in what happened before 1 second. DCCougar (talk) 21:09, 14 March 2008 (UTC)
DCCougar wrote: "With statements like this, I am forced to seriously doubt you are a doctoral candidate". Actually you may be forced only to doubt whether I'm a serious PhD candidate i.e. whether I manage to make my PhD when the "mainstream science" is pushing an opinion that matter can be created from nothing, the only argument the Cosmology and Gravitation professors at my university are able to present for the Big Bang. Which is silly since a theory without the necessity of making matter from nothing, as Einstein's universe is, and predicting all the same observations, providing also a reason for them, is a better theory. Why not?
Even if "ALL agree that the big bang theory is essentially correct" four centuries ago ALL agreed that the Ptolemaic system is essentially correct (which of course is, just the Copernican system is better). And luckily, I can prove since 1985 that Einstein's stationary universe is a better theory than the Big Bang, which might be worth a PhD. You just lose the creation of matter from nothing and all that nonsense about the history of the universe "before it was created" and "what happened before 1 second [after it was created]". The Big Bang moves into the history of science like Ptolemaic system did in 1543. Do you think it would be bad for the science (or for the religion)? Jim (talk) 10:13, 15 March 2008 (UTC)
You must think that something is bad with the Big Bang if you block the access to the information about it. Do you think that the public would lose faith in the Big Bang if it knew everything? Jim (talk) 12:28, 15 March 2008 (UTC)
You must have missed this warning at the top of this page:
"IMPORTANT: This is not the place to discuss how you think the universe began. This page is for discussing the article, which is about the Big Bang model, and about what has been presented in peer-reviewed scientific literature about it. See Wikipedia:No original research and Wikipedia:Talk page guidelines. If you wish to discuss or debate the validity of the Big Bang please do so at BAUT forum or talk.origins." (Emphasis added.) DCCougar (talk) 17:38, 15 March 2008 (UTC)
You must have missed my statement "If I wanted to talk about all subjects I'd have to violate no original research policy since those things are the subject of my PhD work and a PhD work by definition is an original research." It means that I'm not discussing the Big Bang here but only your removal of the most important feature of the Big Bang. We discuss just what we are expected to discuss: your edits.
I'm supporting the Wikipedia rules, arguing for the mainstream science, even against my personal POV. You are ignoring Wikipedia rules by removing the important parts of the article since your POV is against the mainstream science (against the lack of conservation of energy in expanding universe, which obviously follows from prof. John Baez's texts and from the presented reliable sources). If you don't understand the subject of the article then maybe you should leave the editing to those who do? Jim (talk) 08:39, 19 March 2008 (UTC)
You know, Jim, I have read over 100 books on this subject, many by Nobel laureates. Mainstream science books. I don't recall ONE of those books giving the slightest mention to your notion of "lack of conservation of energy in expanding universe." So your claim that this is "the most important feature of the Big Bang" is drastically subjective at best, and as far as I'm concerned, it lacks any degree of credibility. DCCougar (talk) 15:45, 19 March 2008 (UTC)
And by the way, would you care to clarify and provide peer-reviewed papers to support your following claim? "...the most important achievement of the Big Bang Theory: the invalidation of the principle of conservation of energy and finally allowing for unity of science and spiritual life?" You're claiming this is mainstream science? DCCougar (talk) 15:51, 19 March 2008 (UTC)
DCCougar, you see, you read over 100 books on this subject and you didn't know that, so it turns out to be "the most important feature of the Big Bang". Because nobody knew this. Such a thing is called a discovery. Phony duscovery in my opnion, but my opinion is not "mainstream". Prof. John Baez's opinion is nowadays "mainstream". And you know prof. Baez opinion. I was shocked, when I learned that "mathematical physicists" started maintaining that "energy is not conserved in general realtivity". I've always known that the expanding universe hypothesis violates the principle of conservation of energy so I didn't take the expansion seriously and I just kept using it as an argument against the expanding universe. I was glad that "mathematical physicists" found finally the same thing but to my bewilderment, instead of rejecting the expanding universe (which would be a painless thing to do), they rejected the principle of conservation of energy (a thing impossible to explain without a supernatural). But they were applied mathematicians, not physicists, so they didn't need to know all the evidence against the creation of matter from nothing. And that's why we have the "mainstream science" going along with religion. Which amuses me a lot. It is the same problem with "mathematical physicists" that Feynman wrote already about.
"The most important achievement of the Big Bang Theory" was an ironic statement as well as the "unity of science and spiritual life". But it is really there in the "mainstream science" even if not yet documented as clearly as it is in professor Baez's statements. In my university most students already believe that energy can be created out of nothing (with some proper magic perhaps) since they are told by "mathematical phisicists" that "the expanding universe is a proof of this". I don't believe in any of it since I know enough physics to understand how it really works (rather simple knolwdge explained already by Einstein) but how a physics student who doesn't have all that knowledge yet, or you, is to find out what is true?

[edit] The Big Bang Theory Basics

The base of evolution is the Big Bang theory. This is the general theory: Before anything, even time nothing (flaw number one) packed together so tightly exploded(NOTE: I can not say it because it was nothing). The explosion was so big planets,suns(stars),galaxys, everything. But they aren't going the same way(flaw number two). So Billions of years later the rocks absorbed the oxygen before it existed (flaw number three) and about one billion years later it rained on the rocks for millions of years (where did it come from and where did it go?) and made Primordial Soup and that became life (what did it eat, how did it reproduce?) and thus Evolution began. —Preceding unsigned comment added by 76.229.179.200 (talk) 20:02, 16 March 2008 (UTC)

At the top of this page, did you notice the red octagon with a hand in the middle? We're well aware of Big Bang and evolution basics, so please debate them at talk.origins. Art LaPella (talk) 21:49, 16 March 2008 (UTC)

[edit] Just how correct is it?

The big bang as you know consisted of nothing. But how did nothing become something? I read "The Big bang Theory Basics" and the big bang is completely absurd and I'm sure whoever made it up wasn't thinking very hard. Also, you've been wondering why there are all these shootings and stabbings, well Evolution has no absolutes, and the people that did those things are taught thier animals! Wich means you can do what feels right, Evolution is to get rid of the Authority of the Law, wich is Chaotic. —Preceding unsigned comment added by 76.229.222.104 (talk) 16:46, 17 March 2008 (UTC)

Science is something that can be demonstrated over and over again. If you can demonstrate the big bang and make another universe why haven't you done it yet? —Preceding unsigned comment added by 76.229.222.104 (talk) 16:48, 17 March 2008 (UTC)

Again, thanks for sharing your thoughts - but please see the top of the page. This is for discussing the article - not the merits of the theory. There are other more appropriate places to discuss your ideas. PhySusie (talk) 15:19, 19 March 2008 (UTC)
Guys, why can't you accept that Wikipedia is not to publish the scientific truth but only the opinion of majority of editors? If the majority happen to be idiots or mystics, this is what Wikipedia is to publish. If you happen to know the truth (or you think so since you tested it observationally which is the only way to test the truth) you should keep it to yourself since in some fields of science (cosmology and gravitation is an example) it won't be accepted by the majority of editors.
The truth about the Big Bang was aready told by Feynman many years ago so it doesn't need to be repeated. The tuth is absolute and eternal. Like laws of Pythagoras and Archimedes and so it can't be changed. What would you understand about the nature if laws of Pythagoras and Archimedes were modified every time someone coms with a better idea and tries to modify the Wikipedia article according to her idea, removing from the article what majority of editors already agreed upon, or adding what she tested as the truth?
The proper place for scientific truth are a few scientific journals (the fewer the better) since it allows those who control the science a better control over it and it prevents the spread of truths that might hurt the important people in science. Imagine the Big Bang got falsified. Where all the mathematical pysicists would find new jobs in our collapsing economy? Jim (talk) 09:43, 20 March 2008 (UTC)
Ironically, we have here a religious fundamentalist (76.229.222.104) who rejects the Big Bang because it's "evolutionist", and is being supported by someone (Jim) who is apparently a militant atheist and rejects the Big Bang because it's "supernatural"! However, neither view is helpful here (furthermore, observation supports the theory that the Universe is of finite age and has changed over time: if it didn't expand from a point, then presumably it was "poofed" into existence at its current size: would this not be "supernatural"?) --Robert Stevens (talk) 10:20, 20 March 2008 (UTC)
This would be extremely supernatural. So the best approximation (at least for Jim) it is that the universe was always here, not even evolving too much (to keep the Copernican principle as a perfect cosmological principle). Jim (talk) 11:11, 20 March 2008 (UTC)
What the editors, specifically the consensus of the editors, go by is scientific consensus. It doesn't matter what the majority believes, but what the scientific community does. Editors here merely determine how it should be explained for the sake of us common man. It seems your original research was rejected for inclusion multiple times (that, or I got the wrong user), if so, then it did violate what Wikipedia stood for and does not warrant for you to say that these editors are idiots or mystics. You seem to forget the fact that we are a secondary source, getting information from primary and secondary reliable/credible sources, not trying to outline a new horizon in the knowledge of a subject. Here's an example: if the absolute truth was that 2 + 2 = 4, yet most if not all primary and secondary sources claimed 2 + 2 = 5, then Wikipedia must say 2 + 2 = 5. It's a poor example and implies the Big Bang is bogus (I am in no way claiming that), but it does reflect how critical the consensus of credible sources are to Wikipedia. --BirdKr (talk) 06:52, 21 March 2008 (UTC)
I may agree with you, although, as you say, wikipedia could "teach" bogus theories as if they were "truth" (the generic lay-man user would think that that is "the truth", because it is in an enciclopedia), but this editor's point of view has to be said clearly for the users, in my opnion. As a start, for example, the first sentence in the introduction is: "The Big Bang is a cosmological model of the universe that has become well supported by several independent observations." The expression "supported by observations" very often depends on interpretations and different theories/hypothesis may explain the same observations very fine also. What should be written/added, AT LEAST, is something like: "The Big Bang is a cosmological model of the universe that, according to the majority of cosmologists, explains satisfactorily well several independent observations". If that crucial expression is left out of the sentence, then wikipedia is assuming an absolute truth over this issue, which as you said is not what the editor's claims to be publishing. (Epleite (talk) 17:52, 29 May 2008 (UTC))
You might address the oft-repeated counterargument: that "majority of cosmologists" is so overwhelming that emphasizing it in the very first sentence exaggerates the (tiny) opposition among professionals. Or if you like reductio ad absurdum, the arithmetic article doesn't say "2+2=4 according to the majority of mathematicians". Art LaPella (talk) 20:52, 29 May 2008 (UTC)
No it doesn't, it merely informs people what is actually happen. And if the sentence is left the way it is, then it is clearly innacurate (because, like I said, "supported by observations" is a matter of how one interpret the observations) and any scientist would confirm what I am saying. You may be aware of this, but lay person not. Of course, math is the only "place" where you often have what could be called "absolute truth" or proof beyond any doubt. But that is definitely NOT what happens in natural sciences. If you think so, then I am sorry but you should not be editing a scientific article.

(200.161.55.11 (talk) 03:47, 30 May 2008 (UTC))

Even 2+2=4 is philosophically uncertain  – I might be hallucinating, brainwashed, or living in a 99th century holodeck that manipulates my mind. But the counterargument is that the Big Bang is considered certain enough among professionals, and that's what Wikipedia goes by. Later on the article expresses doubt, but putting it in the first sentence could exaggerate that doubt. Art LaPella (talk) 04:44, 30 May 2008 (UTC)
No, putting it in the first sentece would inform the user the truth about the subject, which is that not every cosmologits is adept to the big-bang theory, specially outside of north-america. The lack of world-wide statistics about what percentage is adept makes it impossible to claim that the majority is "so overwhelming", as you are claiming. (Epleite (talk) 18:06, 30 May 2008 (UTC))
In previous repetitions of this old argument you might read in various archives, I found "statistics" by comparing Google Scholar hits on the phrase "Big Bang" to the best-known alternative "Plasma cosmology". Beyond that, I leave this issue to others as I am not a professional scientist, although previous debate gives me the impression that dissenting cosmologists (defined as doing cosmology for a living) can be counted on one hand. Art LaPella (talk) 03:14, 31 May 2008 (UTC)
Hi BirdKr, Excelent example but you may have a wrong user since I understand that Wikipedia is meant for a common man, epecially the high school kid. So I never try to confuse her neither with any unscientific stuff nor with my original research (which of course I have as any guy who works in science). I understand all those things, just some editors don't, and they try to fix 2+2=5 as 2+2=12, which might be the same thing, just in different notation. What I'm doing then is to explain to those editors that the right notation (understood by the common man and woman) is 2+2=5. I may tell him that I'm not pushing my POV since privately I think that 2+2=4 but we aren't to write private articles that would produce chaos and confuse common man. I said that "if the majority [of scientists] happen to be idiots or mystics, this is what Wikipedia is to publish" (your example with 2+2=5, so as you see we both agree on it). But some editors vote 9:1 on 2+2=3 while mainsteam science says 2+2=4. E.g. it happens with gravitation "a natural phenomenon by which all objects with mass attract each other" according to those editors, who voted 9:1 for Newtonian gravitation (and prevailed) over Einstein's which they didn't understand and of course the mainstream science is 10:0 for Einstein. That's why I think you might have the wrong guy. Because of this and since I'm using Wikipedia to popularize Einstein's theory which is rarely understood and then it might look like pushing my POV. And incidentally, Einstein's theory doesn't support the BB despite the attempts to patch in the support for the BB. Einstein's idea of metric tensor being non symmetric coincides with Jim's but Jim is even more crazy since his metric is also degenerate (although it approximates Minkowski) i.e. it has a property that the spacetime volume (dt \times dx \times dy \times dz) is zero everywhere. Jim (talk) 14:06, 21 March 2008 (UTC)

Note that I'm only a physics and math undergraduate student right now so some of the things you've said may have been ignored. Basically it seems you're trying to explain Big Bang under Relativistic and Quantum physics in substitution for the Newtonian physics, after all, Newtonian physics merely provides an approximation to the other two physics mentioned which are regarded to be "better" (for the lack of words), more accurate, and preferred by the scientific community. However, despite all this, how does one explain the Big Bang? You wrote that using Einstein's theories (part of relativistic physics I should assume) disproves the Big Bang theory so there's no sense on using that to explain the Big Bang. If this true, you should note it in the criticism section of Big Bang, forwarding readers to quantum and relativistic physics and Superseded scientific theories. Or you can write another section in this article explaining the Big Bang under non-Newtonian physics and how there are some disagreements or total rejection, just try to add credible sources as much as possible if you do. If you do go ahead with this, it is advisable that you post your draft in the Talk page just so you can respond and clarify to other editor's comments to avoid a revert war. Overall though, is to use credible sources to state your claims, avoiding subjective terms, and keep your agendas as far away as possible when contributing. We're here to improve the article, not to redefine it to a "more correct" or "preferred" view (I put in quotations to note that "correct" to one person may be "more false" to another).

If you can't find any reliable and credible sources (such as scientific journals that to you "dictate" scientific truths) to substantiate the statements, then I'm sorry to say that it has no right to be posted on Wikipedia, regardless of whether it is the truth or not or accepted by the "silent" scientific community.--BirdKr (talk) 16:31, 21 March 2008 (UTC)

I'm not trying to disprove the Big Bang. I'm only trying to turn attention of DCCougar to the fact that the Big Bang contradicts the conservation of energy. This is also what the mainstream science says about the Big Bang and every mathematical physicist working in the field proving it with his math. I say opposite but I'm not a mathematical physicist. I'm just a regular guy with MS in electronics. I just know enough to show that observational data are consistent with the conservation of energy. It is of course no big deal, just contradicts the mathematical physicists's theory that the universe is expanding, and also the Big Bang hypothesis, which is not my fault that astronmers got data which does not support the Big Bang and require dark energy to save the mathematical physicists's theory.
Since I'm doing my PhD work in it I know all of it and I gave DCCougar refs that he doesn't want to look at, maintaining that he never heard about the necessity of non consrvation of energy in the Big Bang, and that this is my duty to present the concrete refs. I did, but Apparently professor Baez's testimony isn't good enough for DCCougar.
The irony of the situation is that it's not good enough for me neither since I'm of the same opinion on conservation of energy as DCCougar. But in Wikipedia we aren't supposed to write our private opinions but the mainstream science's opinion which incidentally is professor Baez's opinion and all the mathematical physicists around the world. So I think that DCCougar says 2+2=4 and I know for sure that the mainstream science says in this case 2+2=5 (speaking figuratively) since I showed it already 22 years ago. It is not in the mainstream since it was not published in a scientific journal. It was "not interesting enough to be published since there isn't any new physics in it". And of course there isn't since the conservation of energy is known for about 300 years. So we should support Wikipedia rules and write 2+2=5 as long as mathematical physicists of the world support it. But DCCougar objects to it and for some reason tries to make an impression that I am an idiot who thinks that he's smarter than anybody on the internet. And this is the whole silly issue. Nothing really important. Jim (talk) 20:27, 22 March 2008 (UTC)
Jim wrote: "I never try to confuse her neither with any unscientific stuff nor with my original research (which of course I have as any guy who works in science). I understand all those things..." Jim, I find it difficult to fathom how you can be so self-assured that you are so much smarter than anyone else on the internet, but at the same time your own webpage relates how your so-called research has been rejected for publication, and that all your subsequent contacts with numerous professionals, apparently in an attempt at some small validation, has only confirmed that such rejection was appropriate. Methinks thou art a bit too full of thyself.
By the way, your webpage appears to be infected with a virus that attempts to infect visitors. And you used to be into programming? Hmmm.... DCCougar (talk) 02:10, 22 March 2008 (UTC)
Why are you so self-assured that you think that energy is conserved? I just think the same thing so why is it so strange?
And why is it strange that the proof that if energy is conserved then the universe isn't expanding were rejected for publication? Isn't it showing to you that the mainstream thinks that energy is not conserved, and didn't prof. Baez told you already the same thing, and that's why what I have shown doesn't matter. How would you explain the events if the mainstream (or prof. Baez) thought that energy is conserved? Could they ignore my derivation of the redshift based on conservation of energy? They couldn't since they think logically.
So even if you didn't think, that the mainstram thought, that energy was conserved, the rejection of my paper for publication should prove, as the only logical possibility, that the mainsteam thought that energy is not conserved, and so my proof doesn't matter. Do you finally get it?
So now you may believe what anybody familiar with contemporary physics see around the world, that mathematical phisicists don't believe in the conservation of energy since their (assumed) math tells them that there is none. And so the choice is only to believe either in conservation of energy and that their math is defective (as I do) or to believe their math and that the energy can be created (as mainstream does). So a conflict that we have here is between the physics (the facts from which principles are derived) and the assumed non conservation of energy -- since math is as only good as its assumptions. So in this case mathematical physicists argue against facts established by regular physicists, assuming non conservation of energy and so far the mainstream is on their side. Which means we need more observational data to tell who is right. Everythig would be fine if the mathematical physicists didn't block the necessary observations as "unnecessary". So the issues are more complex than just presence in it of one stupid Jim.
And what would you like me to do about the appearance of infection of geocities.com? Some practical advice? Jim (talk) 23:20, 22 March 2008 (UTC)


It seems you have learned some obscure point regarding the theoretical General Relativistic treatment of the conservation of energy, and with that you think you can overturn the enormously broad Big Bang theory that is supported not by a single obscure fact but by numerous independent lines of evidence! What does your nearsightedness say about the CMB? What about the acoustic peaks observed in the CMB? What about the abundance of the elements?
I am aware of John Baez's paper, Is Energy Conserved in General Relativity? (http://math.ucr.edu/home/baez/physics/Relativity/GR/energy_gr.html) I am also aware that his answer is not exactly a slam dunk, particularly when he opens the paper with, "In special cases, yes. In general -- it depends on what you mean by "energy", and what you mean by 'conserved'." He also goes on to say, "…GR introduces the new phenomenon of gravitational waves; perhaps these carry energy as well? Perhaps we need to include gravitational energy in some fashion, to arrive at a law of energy conservation for finite pieces of spacetime?... Casting about for a mathematical expression of these ideas, physicists came up with something called an energy pseudo-tensor… Now, GR takes pride in treating all coordinate systems equally. Mathematicians invented tensors precisely to meet this sort of demand -- if a tensor equation holds in one coordinate system, it holds in all. Pseudo-tensors are not tensors (surprise!), and this alone raises eyebrows in some circles. In GR, one must always guard against mistaking artifacts of a particular coordinate system for real physical effects." Yes, Baez's paper is quite complex, and bully for you if you can slog through it with a complete understanding, but your fixation on this conservation of energy thing as if it's the greatest paradigm shift in the history of science is engendered by a common sophomoric exaggeration of the importance of one's isolated realization.
You would do well to keep up with the literature; for example Matt Francis et al.'s Expanding Space: the Root of all Evil? (http://adsabs.harvard.edu/abs/2007PASA...24...95F) The common view is that space itself is expanding. We use analogies like balloons being inflated or expanding loaves of bread. These are helpful. But they are analogies, and there are limits where they break down as they meet the technicalities of General Relativity, which is, after all, what Big Bang cosmology is based on. For instance, Francis et al. say, "What efficacy then, if any, do the common expanding universe analogies have? The balloon-with-dots or bread-with-raisins analogies, like any analogies, are useful so long as we are aware of what they successfully illustrate and what constitutes pushing the analogy too far. They show how a homogeneous expansion inevitably results in velocity being proportional to distance, and also gives an intuition for how the expansion of the universe looks the same from every point in the universe. They illustrate that the universe does not expand into previously existing empty space; it consists of expanding space. But using these analogies to visualise a mechanism like a frictional or viscous force is taking the analogy too far. They correctly demonstrate the effects of the expansion of the universe, but not the mechanism. That they fail at some level is hardly surprising: we’re representing 4-dimensional pseudo-Riemannian manifolds with party supplies." Also, you think you have an alternative explanation for the cosmic redshift? I doubt you understand what GR actually says about the redshift. To say that the wavelengths of light are stretched as it travels through expanding space is a simplification that is not even present in GR. As Francis, et al. clarify, "Technically, cosmological redshift is ...caused by the photon being observed in a different frame to that which it is emitted... The difference between frames relates to a changing background metric rather than a differing velocity..." Different background metrics mean different lengths for "meter" sticks... or spectral shifts.
But again, this is the type of discussion welcomed at the BAUT Forum, and specifically unwelcome on Wiki discussion pages. DCCougar (talk) 02:39, 23 March 2008 (UTC)

Holy smoke, Jim, this is a horrendously misunderstood and misleading statement about the nature of science! There is no such thing as "absolute truth" in science. Religion has absolute and unchanging truth, but not science. Science is a process. Current science is built on centuries of scientific progress and consists of our current best explanations for all the observations that have been compiled over that time. But science in the next century will surely have differences and be more advanced than what we know today. What were you thinking? DCCougar (talk) 02:55, 23 March 2008 (UTC)
How different the laws of Pythagoras and Archimedes do you expect to be? If the universe is stationary, how can you change this with new discoveries? These are rhetoric questions just meant to help you to realize that science discovers only the absolute truth (if it's not absolute it isn't science but either religion or magic). This is its only value (for the non scientists of course and I'm not concerned here how much profit some scientist, priests, or mathematicians have out of the Big Bang, I know its a lot, but I'm concerned here with physics only).

The Problems with the Big Bang

1- The Big Bang Theory

The Big Bang Theory theorizes that in the beginning of time nothing decided to pack together as tight as possible. Then it exploded. The explosion was so big it made solar systems, moons, stars, and every thing we see today.

It does nothing of the sort. Please learn a little about an idea before you attempt to criticize it. DCCougar (talk) 02:13, 27 March 2008 (UTC)

Well, I have heared of two theorys of the Big Bang 1. Nothing packed together so tightly it exploded. 2. A cosmic egg was sitting in space for unbelievebble amounts of time (but where did Time, space, and matter come from?) and then it exploded either way it's sounds like a science fiction novel and that's all it is. And, why are the planets spinning opposits of some others?

...Nope, both of those "theories" are nonsense, and have nothing to do with the actual Big Bang theory. And the rotations of the planets aren't a problem for the actual Big Bang theory either. This page is for discussion of improvements to the article, which is about the actual Big Bang theory: not some other theory proposed by some crackpot. If this continues, I'll delete this section of the talkpage (including the stuff below this paragraph) as off-topic. --Robert Stevens (talk) 18:22, 27 March 2008 (UTC)

2- The Problems with the Big Bang

1. There would be no way to pack “itself” together

2. No way to expand it. How can you expand what isn’t there?

3. If it exploded the matter coming out would go in the same direction forever

4. There is not enough anti-matter in the universe. Anyway all the anti-matter would destroy all the regular matter

5. Everything cannot come from nothing

6. Matter is just matter. Not a special matter to make stars.

(Don't start line with spaces!)Jim (talk) 14:49, 29 March 2008 (UTC) Recipe: Nothing (very hard to find), Magic Vacume (even harder to find), Protective clothing (expensive), and last but not least, frictionless space. Tell your friends and relatives because you might not come back. Tell your neighbors to step back. BOOM! You might not survive. Test this and we'll see if it's really science. Also, there isn't any scientific proof evolution is true!

[edit] Is the universe expanding?

I was wondering what is the proof that the universe is expanding? Is it because the redshift on standard candles? Is there other proof?

My understanding is that gravity can bend space. If a great mass passes in front of light could one see a redshift since the distance now is farther than it was? the speed of light should be constant but I think that it relatively has to go father in the same time. thus the redshift. Is this correct?

Also if the above is correct. What would be the effect of mass that was spread over great distances. Where I am going with this is :

Could dark matter spread out over billions of light years cause a red shift in the light from a star that is not moving away from us in absolute terms? The thought is that the amount of dark matter that the light passed through could have quite a bit of gravity. Thus making far away objects appear that they are moving farther away from us quicker than they actually are.


--Tommac2 —Preceding unsigned comment added by 69.249.66.67 (talk) 04:32, 22 March 2008 (UTC)

"If a great mass passes in front of light could one see a redshift since the distance now is farther than it was?" I think that is correct but you seem to have overlooked what happens when the mass goes on by, reversing into a blueshift. To get such a redshift from dark matter, it wouldn't be enough for the path from the light to be longer once. It would have to keep getting longer and longer somehow, and for all distant galaxies, and I can't imagine what would cause that. Art LaPella (talk) 05:37, 22 March 2008 (UTC)


OK makes sense. So lets take this a step farther. Lets say that the amount of dark matter in the universe is growing at a constant rate equally distributed accross the universe. That means that the amount of dark matter that the light from a distant star passes through is increasing. Thus the light is effected by an increasingly larger net gravitational field. In theory couldnt that cause a permanent red shift? --Tommac2 —Preceding unsigned comment added by 207.45.240.18 (talk) 14:05, 24 March 2008 (UTC)
For a few seconds it would, but after that I think the dark matter would have to grow fast enough to crunch everything. http://www.bautforum.com/questions-answers/ would know that answer better than I would. Art LaPella (talk) 20:55, 24 March 2008 (UTC)


Art's right. As the light approaches a large mass, the gravity causes blueshifting; then as it departs, it is redshifted. Overall, the effect is essentially canceled. In another situation, if light is generated at or near a hugely massive body, it is simply redshifted as it climbs out of the "gravity well." However, calculations show that the amount of this type of gravitational redshifting is very small - practically negligible - when compared to the redshifting due to cosmic expansion. By the way, as the top of the discussion page says, this really isn't the place for this type of discussion. These types of questions are welcome at the Bad Astronomy and Universe Today Forum (http://www.bautforum.com/) in the Questions and Answers section. And, Jim, you should be discussing your ideas and "discoveries" there, too, in the Against The Mainstream section. BAUT is a moderated forum, and you will be asked to read and abide by the rules. If you are proposing a new theory, you will have to defend that theory in detail and answer questions put to you. DCCougar (talk) 14:06, 22 March 2008 (UTC)
But I'm not proposing any new theory. It's old Einstein's theory. It's called "Einstein's universe". I just gave it some supporting math based on an assumption that energy can't be created. The math that either didn't occur to Einstein or he didn't care to argue with mathematicians. Jim (talk) 23:35, 22 March 2008 (UTC)


As previously pointed out, Einstein's (static) Universe was discarded over 70 years ago. It is now very much Against the Mainstream, and that would be the appropriate place to discuss it at the BAUT Forum. The BAUT participants are not so easily shaken by mathematics. In fact, they demand it. Are you afraid your cherished idea will be chewed up and spit out when presented to people who are well studied in the field? DCCougar (talk) 03:10, 23 March 2008 (UTC)


If Einstein's Universe turns out to be ours what will you do? Will you move somewhere else?
OK, I'll try the BAUT. Maybe there is some intelligent life out there. But then I might not have the time to come here and try to explain the pysics to you. Unless you go there with me. Jim (talk) 10:52, 23 March 2008 (UTC)

[edit] Big Bang vs White Hole / Steady State.

I was watching a special on the Big Bang ( part of The Universe series ). As they spoke it seemed all of the claims they made could also be applied to a white hole.

From my understanding they claimed that people found out that the universe was expanding and logically they were able to calculate when the universe was a singularity. They claimed that the entire universe was once a point smaller than an electron.

Then they discussed that seeing that the universe is expanding crushed the idea of a steady state universe.

However could the proof of the big bang be the same proof as a white hole / black hole pairs and indeed a steady state universe?

What are the differences of the big bang and a big white hole?

The article says "Little is known about the earliest moments of the universe's history." In particular, we don't know if the same laws of nature applied, so there isn't much to say other than listing guesses. Art LaPella (talk) 05:47, 22 March 2008 (UTC)


Again that sounds very much like inside of the event horizon of a black or white hole. --Tommac2

[edit] Real particle formation

Presumably there were real particles at the initiation of inflation. I once read that large scale CMB variation arises from the formation of individual real particles (in pairs presumably) during inflation, each of which corresponds to a large volume at the end. Now only virtual particles appear ex nihilo, so that deserves explanation. I assume it is required by conservation of energy, but then what type of particles -- why not just photons or neutrinos or whatever? Fairandbalanced (talk) 22:47, 24 March 2008 (UTC)

Was it "particles" that were inflated to become the tiny density variations in the CMB, or was it "quantum fluctuations"? Leon Lederman in The God Particle said at page 400, "One has to go to the quantum phase of the universe's history, in which spooky quantum mechanical fluctuations during inflation can lead to the irregularities. Inflation enlarges these microscopic fluctuations to a scale commensurate with galaxies." At any rate, a virtual particle can become real if for some reason it is unable to rejoin its pair partner. I imagine inflation certainly presents such an opportunity. But on the other hand, google on ("particle production" "after inflation"), and it appears the current mainstream view sees all the particles in the universe being generated from the extreme energy released as the inflaton field decayed to its ground state... or something like that.

[edit] Criticism of the theory

Big Bang#Criticism of the theory is about 1/40 of the article. Part of it duplicates material in the history section. As for Arp and Lerner, as I understand it they don't account for anywhere near 1/40 of current scientific opinion. Although I sometimes worry that minority opinions aren't allowed to be expressed in their own articles, in this article people want to read about the Big Bang theory. So doesn't this much minority opinion belong at articles like Non-standard cosmology? Art LaPella (talk) 01:56, 9 April 2008 (UTC)

I share the same concern about minority opinions. As much as I support putting the focus on the generally accepted theory in any given field and would oppose giving too much weight to minority opinions, I do think that an encyclopedia's role is to document all the relevant (and verifiable) information rather than simply report what the majority group says. This seems to me even more important in an article about the Big Bang, where science and philosophy meet (perhaps some more material in this regard could be welcome, especially about infinity implications, but I leave it to others).
You raise a good point that people want to read about the Big Bang theory, although the larger audience, imo, is likely to expect something about the dissenting scientific views. --Childhood's End (talk) 02:57, 9 April 2008 (UTC)
There are no "dissenting scientific views" in this instance. There is consensus that the Big Bang is the only model left that explains all observations. Sure there are mavericks out there, but they aren't taken seriously. There are also mavericks who dispute that Maxwell's Equations are correct. This doesn't warrant mention in that article for the same reason. Fringe groups are marginalized at Wikipedia because they are marginalized outside of Wikipedia. If you want to see them included, encourage them to become less marginalized outside of Wikipedia. ScienceApologist (talk) 13:24, 9 April 2008 (UTC)

Actually WP:Undue weight doesn't say we are to document all the relevant and verifiable information, although it can be documented in articles devoted to minority opinions. We wouldn't want the article to be overrun with every possible opinion about it. The oft-debated issue here is how much text should be devoted to each opinion, and comparing the text ratio to the scientist ratio is a good objective test. As the undue weight policy puts it, "in proportion to their representation among experts". If people want the story on dissenting scientific views, as I understand it the answer is that scientists have debated the issue in the past, and now they are pretty much united. Dissent is largely limited to blogs and an amazing number of Wikipedia editors, but among professional scientists the support for such dissent is nowhere near 1/40 (according to previous debates). So I don't understand devoting 1/40 of the Big Bang article to it. The link to Non-standard cosmology covers the subject without exaggerating it. Art LaPella (talk) 03:59, 9 April 2008 (UTC)

I shortened the section. It's now restrained to two paragraphs, with half of one actually devoted to critics of the critics. Hope it satisfies both readers and editors. --Childhood's End (talk) 11:28, 9 April 2008 (UTC)
The section shouldn't be here at all. We've discussed this many times. Please read the archives and get back to us. I removed it completely. Until you have a new argument to make, do not add this fringe material back. Thank you. ScienceApologist (talk) 13:15, 9 April 2008 (UTC)
Archives are quite large. Can you find for us the discussion about Alfven? Also, there's a fine line between WP:FRINGE and WP:IDONTLIKEIT that I suspect might be relevant here. --Childhood's End (talk) 13:54, 9 April 2008 (UTC)
IDONTLIKEIT is a rationale to avoid in deletion discussions. I think what you are looking for is something like WP:NOT#CENSORED. In any case, the discussions are mammoth, I cannot point to a single section of the archive. However, if you want to propose adding more to this article, I suggest you read the entire thing. Also, please note that a 1984 paper and a 1991 book isn't exactly up-to-date, even if you are to buy the mythology that there is a controversy. ScienceApologist (talk) 13:57, 9 April 2008 (UTC)
I dont think there's a real controversy in the litterature, actually. I only see that there are some (minor) dissenting views that are both notable and verifiable, and that should thus be noted since WP must cover the notable and verifiable viewpoints. That's all. --Childhood's End (talk) 14:23, 9 April 2008 (UTC)
The "viewpoints" are only prominent with respect to the history of the Big Bang. There is no prominence of contemporary criticism. Plasma cosmology is not a critique recognized in the sources and the dissent is not worthy of inclusion in a section like that. ScienceApologist (talk) 14:27, 9 April 2008 (UTC)
I'll be glad to hear from other viewpoints as my mind is not set towards one solution or the other. Perhaps it's more relevant to the history section. But I see a strong presumption in favor of including the dissenting viewpoint of a Nobel physicist in an article such as this one. He might not make a controversy on his own, but he's both notable and verifiable, which is the standard inclusion criteria. Still waiting on any archived link about Alfven if you dont mind. --Childhood's End (talk) 18:24, 9 April 2008 (UTC)
Do an archive search yourself, I cannot be bothered to educate you about why Alfven's cosmology is completely irrelevant to Big Bang when this has all been hashed out before. Nonstandard cosmologies is where you belong, not here. ScienceApologist (talk) 18:33, 9 April 2008 (UTC)
Perhaps it belongs to nonstandard cosmology. That's what was being discussed on this talk page before you rushed in with your own pov. Pushing scientism is not more acceptable than pushing fringe theories. I found little material in the archives about Alfven. It seems agreed he's notable, but that his cosmology theory is not. Perhaps what should appear is a note of his thoughts about the Big Bang's merits while leaving out the reference to his alternative theory. What seems clear to me is that a dissenting opinion coming from a Nobel prize in a scientific field warrants inclusion in any article. --Childhood's End (talk) 19:11, 9 April 2008 (UTC)

This discussion has already happened before and it was determined that the place this idea belongs is on nonstandard cosmology. Alfven's thoughts on the Big Bang deserve no more mention than any other Nobel physicist's thoughts, and we have nearly one hundred to choose from. It's incidental to the theory itself and therefore does not warrant inclusion in this article. Please see WP:WEIGHT and WP:FRINGE for more. ScienceApologist (talk) 19:14, 9 April 2008 (UTC)

Just to add on to this (and to give some moral support): Pushing scientism is not more acceptable than pushing fringe theories. This one made my jaw drop. Of course it is more acceptable, just as pushing fact is more acceptable than pushing fiction. Alfven might have a Nobel, but that does not give his ideas in unrelated fields more weight! He might as well have won the prize in Biology. His stuff is from the 60s, and the last 40 years have shown that the theory is a failure. Why would we want to reheat this old pile of... ? --Dschwen 21:50, 9 April 2008 (UTC)
Here is another representative quote about Alfven from previous debate. I don't really know if Alfven was right, but Wikipedia isn't about my opinion, and it seems clear that Alfven's importance today is more historical than anything else. Art LaPella (talk) 22:02, 9 April 2008 (UTC)
@Dschwen, I think you misunderstood my comment since 'scientism' can be interpreted in a number of ways. Epistemology is part of science, and trying to push in Wikipedia that science can produce either undisputable truth or that science is a better source of knowledge than, say, philosophy, in all areas of life and nature is not supported and is unscientific in itself. What this article, and all scientific articles, should do is to report the state of the science as it exists, with the proper context and history, etc., without pushing either fringe theories or scientism, which are not scientific.
As to Alfven, I think that what the reader would expect to find is his view of the Big Bang, not necessarily his alternate theory, which I agree is discredited. That should have been left out right from the start. --Childhood's End (talk) 00:15, 10 April 2008 (UTC)
Yawn. We've been over this. Nothing to see here folks. Move right along. ScienceApologist (talk) 08:29, 10 April 2008 (UTC)

[edit] Censorship

My citation to "The pre-big bang universe" at BigCrash.org was removed, claiming conflict of interest. This is about science not about politics, if the model can be discredited by science then do so, otherwise do not censor me. My only interest is in finding the scientific truth, where ever that leads. A critical review of the model includes "...you may have stumbled onto some new explanations that would explain observed physics." Challenge the content on science, not politics. --Jtankers (talk) 23:36, 11 April 2008 (UTC)

Challenge the content on Wikipedia policies, not on science alone. In particular, please study the Wikipedia:Conflict of interest guideline. Art LaPella (talk) 01:32, 12 April 2008 (UTC)
You may also want to study the Wikipedia:No original research policy. If you can persuade other scientists that your ideas have merit - for instance, by publishing them in a peer-reviewed journal - then they would become appropriate to cite on Wikipedia. However, at the moment, they're not. Scog (talk) 15:57, 12 April 2008 (UTC)

[edit] Scientific Critiscim

I think it would be a good addition to the article to add critiscisms of the Big Bang Theory based on scientific evidence, if it is in support of creationism or not, or just revealing flaws in this theory. It seems like a good idea. Timetobrawl (talk) 16:39, 15 April 2008 (UTC)

Find some reliable, peer reviewed sources that have received note on the subject and we'll consider it. ScienceApologist (talk) 21:51, 15 April 2008 (UTC)

There are plenty. One that quickly comes to mind is:

Mitchel, W.C., 1997, Big-Bang Theory Under Fire. Phys. Essays, 10(2), 370-379.

Of course, the observations and evidences mentioned and discussed in the article are scientific, not religious. Other papers cited in this article are also peer-reviewed. That would be a start for what you want to consider, but there are newer papers too. (Epleite (talk) 17:14, 29 May 2008 (UTC))

Phys Essays is not peer reviewed. Try again. ScienceApologist (talk) 05:20, 31 May 2008 (UTC)

[edit] Origin of the Universe?

I went to the article origin of the universe and it redirected me to the big bang. The big bang does not explain the origin of the universe, it merely explains the construction of things within the universe. Is it possible to start a new article on origin of the universe? (Including information about how/where that original bit matter required for the big bang to even be possible originated from) 24.5.246.233 (talk) 05:30, 17 April 2008 (UTC)

There are no well established theories beyond the current big bang model. There are some examples of ideas that some people have been developing under "speculative physics beyond the big bang" in this article, but this section is small enough that I don't think it is necessary for it so be split off into its own individual article. Coffeeassured (talk) 08:06, 17 April 2008 (UTC)
OK that's great. Maybe in the future there will be more information on that subject. Thanks for your input.24.5.246.233 (talk) 19:22, 17 April 2008 (UTC)

[edit] NPOV tag

The NPOV tag links to WP:NPOVD which states "Drive-by tagging is strongly discouraged. The editor who adds the tag must address the issues on the talk page, pointing to specific issues that are actionable within the content policies,..." So we'll give KirbyManiac half an hour or so to compose his NPOV objection, before removing his tag. Art LaPella (talk) 00:02, 29 April 2008 (UTC)

No such explanation has been provided, so I removed the tag. Art LaPella (talk) 00:45, 29 April 2008 (UTC)

[edit] Big Breed Theory?

Has anyone ever heard of the "Big Breed Theory" or "Exact Classical Mechanics" proposed by Ron Pearson (e.g., http://www.pearsonianspace.com/second%20page.html)? Some interesting claims are made but I assume they aren't taken seriously outside of Pearson's close circle of supporters. RichardF (talk) 20:06, 9 May 2008 (UTC)

I didn't find a Wikipedia article on Big Breed Theory, Exact Classical Mechanics or Ron Pearson (that Ron Pearson is an actor), so without knowing anything more, it doesn't belong in the main Big Bang article. It may (or may not) be notable enough to have its own article though, with links from some non-standard cosmology articles. Art LaPella (talk) 21:27, 9 May 2008 (UTC)
Thanks. I knew none of those articles were here. All of the Googled pages I found seemed to be interconnected too. That's why I was wondering if there was any degree of independent acknowledgment of the assertions. I can't find any. RichardF (talk) 12:54, 10 May 2008 (UTC)

[edit] Horrendous Space Kablooie

The Horrendous Space Kablooie isn't exactly vandalism. But the usual name "Big Bang" is used 8000 times more often according to Google, so the "HSK" doesn't belong in the first paragraph, and probably not in the main Big Bang article at all. Art LaPella (talk) 23:33, 11 May 2008 (UTC)

Argument by Google count won't fly per se, but if one of those sites listed is an WP:RS then I won't argue. But something like that must be sourced. (I'm one of many that feel "BB" is a misnomer...sad to think it but HSK might actually be an improvement. :P) --Aunt Entropy (talk) 03:09, 12 May 2008 (UTC)

I had never heard of it, but then, I'm no big bang expert. I'm just amazed what some people will edit war for! --Jack forbes (talk) 21:52, 12 May 2008 (UTC)

[edit] Big Bang = Religion

The big bang is a theory, and nothing more. The only difference between the big bang theory and other religions is that this one is government funded... I personaly do not believe in the theory, but like other religions, I have no problem in other people believing. The only thing that angers me is that it is used in modern science books. There is no definate, or even moderately close evidence that proves that this is how the universe was truly formed, whereas when I think of science, I think of information based on facts.

I think you may have a misunderstanding of what "theory" means in the scientific context. A scientific theory is an explanation that has been throughly tested and is supported by the currently available scientific evidence. If you wish to read about the scientific evidence supporting the Big Bang model you will find a good deal of it on this or related pages. Please remember that this talk page is for discussing improving Wikipedia's page on the Big Bang model, not for debating the merits of the theory. Coffeeassured (talk) 02:00, 1 June 2008 (UTC)

I think you meant to say that the beginning of the article doesn't explain the basics very well. It was perhaps written more to impress other scientists, rather than to explain the Big Bang to the rest of us. However, the first sentence in the first picture caption is a better summary: "According to the Big Bang model, the universe expanded from an extremely dense and hot state and continues to expand today." Or better, "...an extremely SMALL, dense and hot state..." Art LaPella (talk) 21:47, 6 June 2008 (UTC)
Now, Art, it wasn't SMALL. It was the entire universe, after all. ScienceApologist (talk) 21:48, 6 June 2008 (UTC)
Yes it was, according to http://www.onelook.com/?w=small&ls=a: "limited or below average in number or quantity or magnitude or EXTENT" (emphasis added). A thesaurus didn't help—it gave a list of words open to similar criticism. "small-sized" might be better. Art LaPella (talk) 04:11, 8 June 2008 (UTC)
But, Art, it wasn't "limited or below average in number or quantity or magnitude or EXTENT". It was the entire universe, from one end to the other, with all the stuff in it. Though the universe is "expanding", the only real sense of "size" we get is from co-moving coordinates. The universe is always the universe: no bigger, no smaller. It's only our rulers which change size! ScienceApologist (talk) 14:41, 10 June 2008 (UTC)
No bigger, no smaller, but expanding. I think you accomplish that paradox by defining "small" to mean "small as a fraction of the universe". I think Metric expansion of space#Metric for spacetime says the position coordinates aren't expanding but the distance formula expands with time (I understand how that choice of coordinates could be made, although I don't understand why that inside-out perspective is helpful.) But Cosmic inflation#Overview seems to use the word "small" for the early universe, whether or not we mean the observable universe. "the only real sense of 'size'" is also puzzling, as the ever-increasing impossibility of living long enough to reach a distant galaxy would seem to be a sense of increasing size regardless of the coordinate system. But OK, I can see how "small" might lead to a can of worms. I just wanted to explain that "the universe expanded" means expanded zillions of times, not 2 or 3. Art LaPella (talk) 01:04, 11 June 2008 (UTC)

[edit] Lead question

The article begins "The Big Bang is a cosmological model of the universe that has become well supported by several independent observations." I'm sure there is a reason it doesn't refer to the Big Bang as the beginning of the universe. Can someone explain why this is?Asher196 (talk) 04:59, 10 June 2008 (UTC)

As often discussed at #Origin of the Universe? for instance, there is no consensus on whether the Big Bang was the beginning. But I agree the introduction should give us a better hint what the Big Bang theory is: "...where the universe came from..." would be a good start. Art LaPella (talk) 05:07, 10 June 2008 (UTC)
