[edit] Notability?
Is this notable? A Google Scholar search for "chronon" only brings up 648 articles, most of which have under 20 citations. [1] --Mike Peel 15:22, 30 July 2006 (UTC)
- Yeah, after reading the article I don't know why I know what a chronon is. It's not referenced in the QM or decoherence articles at all... --HantaVirus 17:06, 31 July 2006 (UTC)
It's not standard physics, although the idea has been proposed. Time is not quantized in standard quantum mechanics, although there is some suspicion that a correct model of quantum gravity will need time to be quantized.--Srleffler 00:21, 1 August 2006 (UTC)
[edit] Universal Slideshow?
"A chronon is a proposed quantum of time, that is a discrete and indivisible "unit" of time, in a theory that proposes that time is not continuous." Time is not continuous...this doesn't seem rational, even considering quantum mechanics. The other three dimensions (those of space), have no quantized lengths, so why would time? Also, a chronon (2×10-23 s) is like 1021 times longer than a planck time, which is the closest that theories can get us to the Big Bang. If chronons are discrete and indivisble, then what does the planck time denote? I dont think that time is quantized into segments. Instead, a planck time is the smallest interval in the continuous "stream" (FLOABW...) of time that makes physical sense to use (explaination). --HantaVirus 15:35, 14 August 2006 (UTC)
There us the notion of an "elementary length," it just tends to be raised more as speculation than as a proven theory. See, for example this definition (defining the elementary length as "a fundamental number λ such that all length measurements would be integer multiples of λ" and here (a discussion that references the "elementary length"). In Loop quantum gravity, the elementary length is the Planck Length and every length is necessarily a multiple of that length. (Reference). --Unregistered User 19 March 2007 18:05 (EDT)
The article states that the Chronon can be derived from using the Planck Length as the wavelength of a wave and calculating the period. Estimating the Planck Length at 1.6e-35 and the speed of light c (3e8), the corresponding period closely resembles the Planck Time (5.33e-44 vs. 5.39e-44). This disagrees with what the article states (1.078e-43). Additionally, suggest adding a link to Planck Time in "See Also" 70.89.226.253 (talk) 18:40, 3 March 2008 (UTC)
Actually, you should set 1/2 a wavelength to the planck length, because the wave has to have time to oscillate up AND down. If you set a full wavelength equal the planck length then it would not be a wave at all; it would be a DC current!
Also, the fundamental length and time limits on the universe are not just theory. They are real and can be thought of as the smallest "building blocks" of our universe, which are photons. Because we measure everything using photons, if you try using a photon to measure something smaller than a photon you won't see anything. It's not saying there is nothing smaller than a photon, but if there is then we can't observe it (at least not using photons).--MaizeAndBlue86 (talk) 21:23, 3 March 2008 (UTC)
[edit] Use in Fiction?
This reminds me of the Discworld book Thief of Time, specifically a concept described as "the cosmic tick"; the time span required for the smallest possible thing that can happen to happen. I don't know if that links directly to this, however, not being a student of quantum physics myself. Redneckgaijin (talk) 01:24, 26 January 2008 (UTC)
- Yes, that's correct. The smallest thing that could possibly happen is light traveling a distance of the planck length. The time it takes that to happen is 1 chronon.--MaizeAndBlue86 (talk) 21:28, 3 March 2008 (UTC)
[edit] yes
This is an observation related to the stub "chronon". I believe the possibility that time is quantized is very real. After all, 10 -43 (10 at the 43rd negative potency)is the time that light takes to cross one planck lenght. Bellow that level space and time as we know them do not exist. I have always considered this to be one quantum of time. I am curious, therefore, to know the reasons why the writer of the stub claims the time quantum to measure 10 -22 secs.
