“Before” the Big Bang is nonsense. It’s equivalent to saying “head north from the North Pole.”
It’s not so much that we know there was nothing before it, but that we can’t figure out what was before it.
No, in our current best-supported model of the universe (Lambda-CDM) the concept of “before” the Big Bang is meaningless. It is the apex of the spacetime “bell” from which everything emerged.
It is incoherent that sonething could suddenly exist out of nothingness.
Clearly the universe does not exist, this is all an elaborate statistical artifact.
To my knowledge, we also have zero evidence that they didn’t exist. Nor have we ever observed matter/energy appearing out of
thin airvaccuum, so it seems unlikely to me.Yeah, I suspect that the universe may expand and contract, so likely all the matter in the big bang came from it all being compressed from the previous cycle.
I also think all total matter gets distributed the same way each cycle, so I guess I think all matter that exists now is the same matter that has existed always.
I also think each cycle, everything happens the same way deterministically, even though it would be exciting to see if maybe events happen differently each cycle.
My crackpot theory is that there’s a universe inside each black hole and we’re currently inside a black hole. All of the matter that a black hole ingests feeds into a big bang on a separate timeline.
The big bang was a singularity where our understanding of time and space breaks down. Well a black hole is the same thing.
And to my knowledge there can’t be a before time.
Oh yeah? Then where did they film The Land Before Time? Checkmat
I like how there are at least three things that are immediately recognizable as wrong with this question.
