The moment before the big bang, the universe was a singularity similar to a black hole though. In fact, our universe shares several properties with black holes (mass/energy can never escape it, for example)
It’s more akin to a white hole. With accelerating expansion It seems everything will escape eventually.
And then ‘accidentally’ observable universe is just slightly below Schweidshield radius which would collapse it back into regular black hole. Seems like a very peculiar coincidence.
So then when the expansion slows and the universe starts contracting (again?), will time then reverse as entropy reverses?
I’m pretty sure nobody thinks the Big Crunch is going to happen anymore, considering the expansion of the universe is accelerating.
I sorta think its still possible. Im not 100% sold gravity is a constant on massive scales.
Except it doesn’t seem like it will ever contract. If universe were to stop or contract, it would collapse into black hole
