Before the Big Bang.....?

Question

OK so this is what I was thinking a couple days ago, please shoot me down if I'm completely wrong...

If our universe is supposed to end with everything getting sucked into a singularity.....and a singularity blowing up is how everything began, than can there have been multiple universes before our big bang? Like everything gets sucked in, then blown up, then sucked in again??

Answer 1

That is a theory that has been put forward before. Is it possible? It could be but there is a problem, we cannot know.

If the universe started at the big bang from a singularity we cannot determine what came before. Of course, the big bang may not even have been at a singularity. It may have been just a very dense area and not a singularity. This is a theory investigated by Andrei Linde at Stanford. Or it may have been caused by a collision of branes.

But lets assume it was a singularity. The general theory of relativity tells us that at a singularity all physical laws break down, all theories are nullified including the general theory of relativity. The result of this is we cannot tell what existed before the singularity from the state of the universe after the big bang. Nor can the state before the singularity have any effect on what came after. The result is we cannot tell whether your theory is true. It is as good as any other.

And, we are not sure but the expansion is probably not beyond the critical rate and may, but it is not certain, collapse at some point.

Answer 2

Since matter and energy can't be created by nothingness, one idea is that both have always been around. One idea is that space is flooded with hydrogen, helium and that enough gravity can create a massive collapse much like stars are formed, except that these collapses are so strong that singularities form which then expand into universes.

Answer 3

The universe is expanding at an ever accelerating rate. It will not fall into a singularity

Answer 4

empty space is very tough to fathom, i can't understand how nothing can be, in the very sense of the word (not thing). if empty space is nothing how do we know it exists. anyway i dont believe the big babng theory, i think the universe just always was. that's also another tough 1 to fathom, but i don't c any reasonable theories of how the universe was created, so i have drawn the conclusion the the universe always was and that there is no such thing as empty space, something must exist within it otherwise we wouldn't know it was there.

Answer 5

Some people say the universe will have too much gravity and implode, i personally don't understand that one. But some people say the universe is going to keep expanding until our solar system falls apart then the planets will rip apart then even the atoms and electrons will split until there's nothing left.

Answer 6

the's 2 theories about how the universe will end.

1. it would keep expanding forever.
2. gravity will pull everything back together.

Answer 7

no, you're wrong...

the world ends when J-Dogg dies
