Proof of the Big Bang?

11 posts in this topic

A Harvard scientist believes he has found proof of the big bang. John M. Kovac led the team which reportedly discovered gravitational waves - ripples in spacetime. The discovery is still set to go before peer review, so don't count your chickens too soon... but we may have proof of the big bang, folks.

 

The NYT article is kind of basic and the pictures part made me feel like I was in second grade. But it did have the information I was looking for otherwise - who, what, when where, why.

 

Enjoy, and please don't start debating religion. We've already had one thread closed down...

I'd hardly say this is the first study that lends enormous credibility to the Big Bang theory, but it is interesting nonetheless.

Yes, but this is in essence the real big proof that science has been looking for. It's kind of the final nail in the coffin for any (edit: scientific-based) doubt. 

 

Other proofs like background radiation being uniform and all of the fundamental forces (save that one S.O.B gravity) being united at very high temperatures lend credence to the idea, but this is really the holdout theory they hadn't proved until now.

So we finally got now the direct proof that the big bang did happened?

This is basically as close as we can get to proving it, other than seeing it.

 

Einstein predicted these gravitational waves, and up until now we had not observed them. Now with proof (if the study holds up to peer review) we'll have proven Einstein's prediction correct. An analogy would be something like a puzzle you haven't solved that only has one piece left. But you can't see the piece, so you can't find it to solve the puzzle. Too literal? :P

 

For anyone interested, Wikipedia has a pretty good picture ( http://en.wikipedia.org/wiki/File:Spacetime_curvature.png ) of what we're looking at. The spacetime (grid) is displaced where the earth sits. Now imagine the earth disappeared. There'd be waves that started propagating as the spacetime moved up and back down again.

 

Edit: The proof of the big bang has been pretty strong for a very long time, but unless the proof is really 100% science isn't going to take it as the truth.

"if the study holds up to peer review"

Ah, see - that's the main thing on the horizon to do next. It's alright taking this as definitive at this stage, but peer reviews and publications need to agree with the findings before the scientific community (and myself) can really say this is further proof of the big bang.

The proof is never 100%. We find the best working model we can come up with and go with it, until something else comes along and we have to change it.

"Direct" proof? Not quite; that's not possible. What we have done is significantly increased the amount of circumstantial evidence for it, which was, as has been mentioned, already overwhelming to begin with.

And yes, all of this is of course assuming the study holds up to peer review.

Is this the same thing that another guy say multiverses were probable?

 

No, this is attempting to give further credibility towards the big bang theory by proving the existence of gravitational waves. The holy grail would be to prove the existence of the graviton, but that's nearly impossible.

 

Multiverse theory is generally considered to be drawn from either other universes outside our own (if ours is not infinite) or within our own such as inside black holes (edit: some also believe that other universes can exist in other dimensions). It's complicated stuff that doesn't have much credibility as of now. The existence of gravitational waves doesn't prove that there are multiple universes.
