One interesting fact with the Big Bang model is that in the very first moment of the universe, it was small enough so that quantum effects should be present. It was in addition so massive that general relativity should apply too. And here is the catch: we have no idea how to model this theoretically. Therefore, the first fractions of second of the life of our universe consists of a blurry period in which we don't really know what happened. In particular, this challenges even a definition of an origin of all times.
Consequently, everything is open to imagination :)
PS: thanks for this interesting blog :)
I think it's hard to imagine because of our comprehension of opposites.
This might be crazy or stupid idea but. "Philosophically" speaking, I tend to think about it in this way; imagine a Big Freeze, where only 1 sub-atomic "particle" is left at the end. That "energy" is so tiny but yet it would be all that there is, and in the infinite nothingness, it would be everything. Super tiny, super dense, yet super massive as it is everything there is.
Don't ask me what happens next though, we're back at those first fractions of the second. xD
As always, thank you for reading and for your valuable input!
I would rather not call a big freeze a case where a single subatomic particle is left, but more a gigantic universe where every single particle is isolated.
I have the impression that what you have in mind is instead a kind of soup of elementary particles like in the first moments of the universe. This would correspond to a big crunch scenario. In this case, the problems of the first fractions of second are the problems of the last fractions of second too. As there is no more time defined in there, we can think long about them :D
Yes, my bad. I actually was thinking of a soup like state (had bose-einstein condensate like state in mind, hence why I said that energy is so tiny, but yet subconsciously thinking fraction of a Kelvin is beyond freezing. So I typed "big freeze" 😁)
I see. It is indeed what I imagined ;)
