I read with astonishment -in several media in connection with this paradox- that a commonly assumed tenet of science is that information cannot be destroyed. I am a physics graduate, never heard of it and it seems to be in contradiction with the second principle of thermodynamics and the foreseen cold and hot deaths of the universe. Worse I cannot find in the whole web anything about this "assumed tenet of science". I think someone should explain it.

[edit] homogeneity and BHIP

I removed the following paragraph which was recently added;

The homogeneity of space and the space-time position independence of the laws of physics is a fundamental assumption of all physics science since Newton. Recenlty, because of the dead end of the Scientific method, scientists like Hawking concluded that the laws of physics are not actually space-time position independant but space-time position bounded, thats why they created the black holes concept and claimed that space or time is absent inside them. The information paradox of black holes is, for some anti-scientists philosophers, the proof that space is not homogeneous and/or that the laws of physics are actually space-time position dependant and not space-time position bounded, as long as, according to the paradox, information seems to vanish or (alternatively) stored to unconventional material (or non-material) objects. Apart from the black hole information paradox, some experiments came also close to the philosophy of the position dependancy of the laws of physics. Some universal constants used in well known equations have been found to change their values (increase or decrease) when measured in small fragments of time or when time passing [1]. A group of pioneer "scientists", lead by John K. Webb [2], continues the experiments in this revolutionary field.

This mostly reads like pseudoscience. The invariance of fundamental physical constants with space and/or time is open to question, and John K. Webb and other's cited may well work on this. However I can't see any connection or relevance to the Black Hole Information Paradox. -- Solipsist 09:16, 10 Apr 2005 (UTC)

[edit] The Equation

This page ought to have the equation which started it all off.

S = c^3xA/4ħG

S=thermodynamics (Entropy), G = gravity, c is einsteinian theory (speed of light). ħ ("h-bar") = reduced Planck Constant (or Dirac's constant). A is the area


The only real way to destroy information, is to destroy the human race. A black hole cannot destroy information because of the fact that if we observe a star, and a black hole consumes it, we still know the star was there....

Now if we destroy the human race, there is no-one to reproduce with or to share data with, thus destroying the facts and information that we have learned...


it is impossible to know, trying to answer this paradox is purely futile. the reason for this is that if the information were destroyed we would have no recelection and it is possible that things are disappearing, however we are uncertain because the information which is the memory no longer remains. A more plausible theory is that information is neither stored or destroyed but recycled, for if it were stored there would inevitably be answers to "the beginning" and if it were destroyed then one would see or wonder about a black hole the black hole would itself cease to exist. thoughts of K.
