this has always interested me, and there is no correct answer. only speculation.
my astrophysics is a bit weak, but the universe can not consist of nothing, as it could not expand into something that is not there… a void is never empty.
but as Azraelz pointed out, this is all educated guesses.
did she say 14 billion or 40 billion years? doesn’t seem like an awful long time considering our sun has little over 5 billion years to go before it dies.
I think she said 14 billion and she does seem to think it started from nothing except the “potential to exist”. I don’t get that either.
Keeping it big, scientists have also theorized about the end of the future of the universe, and they’ve called it the Big Crunch. According to the theory, one day when the universe stops expanding, it will collapse on itself and form a black hole.
