User talk:Pekka.virta/Quantized spacetime

The contents of this article will have to be consistent with what is said at Spacetime. In particular, its importance for the development of a theory of everything has to be explained. As it is now, it is not very useful to a reader who (like myself) knows only little of theoretical physics. Andreas (T) 14:47, 12 January 2010 (UTC)


 * I've declined the speedy request because you have proposed that this article is merged, therefore we'll be needing this talk page for any discussion to take place.  Bettia  (talk)  15:02, 12 January 2010 (UTC)
 * Thanks, I just wanted to remove the speedy template for the same reason. It appears to me that quantized spacetime and quantum spacetime are different concepts, but this is not clear for the average reader interested in physics and will have to be explained.

I've found the first two references on Google books, here and here, and searching up "quantized" or "spacetime" in either turns up nothing. This suggests they aren't valid sources, though this is only with snippet view. The third reference isn't in Google books but is also so old that it seems less likely to be a source for modern research into SR. Searching the web for "quantized spacetime" turns up various things but I don't know how closely they match the article. -- JohnBlackburne wordsdeeds 16:26, 13 January 2010 (UTC)

The word "quantized" is not used in math. Instead the words "discrete" or its synonym "non-continuous" are used there. Pekka. —Preceding unsigned comment added by Pekka.virta (talk • contribs) 11:04, 21 January 2010 (UTC)

The subject "quantized spacetime" is a speculative subject and there exist not any commonly approved theory about this. I collected here a summary of some mathematical concepts, which are mainly based on discrete geometry and quadratic algebra. Use of the terminology is not established in physics. Quantum gravity does however not belong under this subject. Its math has a quite different base. / Pekka —Preceding unsigned comment added by Pekka.virta (talk • contribs) 12:40, 21 January 2010 (UTC)
