Our space-time began at the big bang. Even decades ago, Stephen Hawking was talking about it like "Since events before the big bang can have no observational consequences, we might as well leave them out of our discussion and simply say that time began at the big bang."
- XorNot 5y agoNo observational consequences means t=0 is zero though - if no events from before then can have carried through consequences, then they might as well have not happened - certainly no information about them can ever be recovered. You are making a very strong assertion that something did carry through - what are you basing that on?
- knodi123 5y ago> then they might as well have not happened "Might as well not" is different from "Did not". That's all I, and Mr Hawking, are saying. In fact, your first sentence is literally just a paraphrase of my quote from Hawking. > You are making a very strong assertion that something did carry through No, I most certainly did not. All I said is, there could have been something, or could have not been. I did not say something did happen prior to the big bang, just that it is wrong to say that it could not have.
- chaps 5y agoYou're also making a pretty big claim about whether a universe makes noise if no dimension is around to articulate it.
- sandworm101 5y ago>> events before the big bang can have no observational consequences There are people working to disprove this. There is a concept floating around that the CMB might contain evidence of something from before the BB. If our universe came into existence within some other universe, then arrangements of large gravitational objects in that universe may have some impact on the early formation of our 'pocket' universe.
