Do you guys think there was another universe before the big bang?

For some reason I was looking up the lore behind Galactus from Marvel and they say the big crunch happened to his universe so he flew into the central point of the big crunch and merged with the sentience of the universe. That's some black airforce energy right there. So what do you guys think...Did time begin with the big bang? Was there something before? There's also the boltzmann brain theory but I can't be bothered to get into that, I barely understand it myself.

I think the universe always has been and always will be, continously expanding and collapsing on itself and starting over. You could say I consider the universe "god" in that sense.

I mean the big bang theory was definitely a good show, but it doesn't mean there weren't any other good shows before it. Like the Sopranos was good, and Star Trek too.

some scientists says that black holes are baby universes expanding on the other side aka Cosmological Natural Selection

I personally don't think the universe was a result of a big crunch, since it would mean the matter that was in the past universe is still present today. But that would mean that our universe has just the mass for another crunch, which is certainly not the case.

I would assume the universe was a random quantum fluctuation in a universe that has reached heat death for a bajillion years. If a similar fluctuation happens in our universe, it would be roughly 10^10^10^54 years from now. Don't even bother to comprehend the magnitude of this number.
If you ever feel bored and are questioning the meaning of your existence, read deez blogs. Maybe you will find your answers.

yes, this universe will end and another will begin.

even if there is no big crunch, the heat death leading to a non energy absolute zero state, only for quantum fluctuations to restart the process of entropy leading to something similar to the big bang still means a start and end of the universe. large timescales still do not mean infinity,.

In the case that black holes are truly dimensional portals to other universes, and if those universes are anything like ours, I am led to assume that the matter that goes into them would have to somehow sink into the other verses. But if that's the case, then we're lacking evidence of "white holes" spitting matter from other universes into our own.

Additionally, and if I'm not outdated, "before the big bang" is a questionable statement, because time doesn't manifest in the singularity, instead it starts with the big bang. This is one of the problematics of finding causes for the existence of this universe - for example, atributting it to God as a creator -, because technically, there is no "before" the beginning of time. But, of course, this is a technicality resulted from the fact that time is a dimension in our universe, but it doesn't necessarily exclude an additional and larger state of time that is not identical to the time we experience, and I guess one could argue that "the arrow of time moves forward" is evidence that there is an underlying mechanism behind the way our universe works in first place.

We might as well mention that quantum physics has been contesting the chronological nature of cause and effect, as @deg brought up to me in a recent exchange.

Perhaps...because if not before, why now?

Big crunch is actually what the originator of the big bang theory later believed iirc.

Boltzman brain is basically just a scientific hypotheses version of solipsism based on probability of a human brain randomly forming in space.
