I watched a TV documentary a couple days ago. A segment of it discusses Hubble's "Big Bang" and how it is tied to mathematical "singularity" (zero, infinity) and such weird objects.

The Big Bang Theory is in a way very much a "creationists" theory. The whole universe just popped up from "nothing" and expanded and filled "void" with "matters" (which is also "energy" according to E=m.c**2). It did not say GOD made a Big Bang. But what happened "before" the Big Bang? Was the Big Bang just a machine that converted invisible energy into matters? Or was it a "dark hole" (another mathematical wonder object) having too much matters (and energy) compressed beyond its capacity to contain -- broke down and released matters and energy into "the void".

There are mathematical questions on what will happen to the universe. Will the Big Bang end? Mathematics can take us back past the origin ("0") into negative "time" zone, ... and marvellous science fictions.

So, the Big Bang is at present under scrutiny. Proofs may be very hard to come by.

In Buddhism, there is little concern about the "beginning" or the "end" of the universe (cosmos); it is prudent to live "here and now".

One "Buddhists brand" (ธรรมกาย) was heard claiming its foundational concept was from a "lost or missing segment from the Tipitaka". It was a very much "tongue-in-cheek" claim.

More likely is this: any part that is missing was not really "lost" but was "excluded" by several "rigorous" (สังคายนะ) canonization councils. Selling tickets to heavens (like concerts) won't be included in the Tipitaka here and now.
