What was there before explosion of Big-Bang ?

Question

I'm curious. ^^

Answer 1

Of all the questions asked in Astronomy & Space, yours is by far the one that gets asked the most. However, each time it's asked the answer is still the same --- nobody...repeat, NOBODY...knows the answer.

Answer 2

No one knows and it is likely that we will never know. We know what the Universe was like only a tiny fraction of a second after the Big Bang, but we'll probably never know what was there before it happened. Some people say that there was nothing at all, but personally I'm a little uncomfortable with that. If there was nothing, then what made the Big Bang happen? Of course, some say that God did it. The truth is, no one knows.

Answer 3

Well.. That IS the question behind almost all science.. But according to Stephen Hawking, it was a point of zero size and infinite density... Before that, it could have been nothing, or it could have been a whole other universe. One theory is that this universe which had a Big Bang is going to also have a Big Crunch. Or it could expand for ever. Or get all eventually sucked into black holes. Your guess is as good as mine.

In any event, what came before the Big Bang is a question of faith. Mr. Hawking references God quite often in his book I read. Its pretty interesting.

Answer 4

I don't think anyone knows or is ever likely to know what preceded the Big-Bang.

Personally, I subscribe to an oscillating universe theory. I.E. a series of Universes without beginning or end. The Universe preceding ours finally ran down. That is to say gravity overcame the expansion and the universe collapsed into a series of Black-holes. The final act was the combining of Black-holes into a single singularity that exploded into what we refer to as the Big-bang. Our universe will eventually run out of energy, be taken over by gravity and begin that collapse ending in a single singularity and yet another explosion.

This concept has no evidence that I know of or that I can site. I became aware of it from a college astronomy professor. She didn't believe it but for some reason it makes perfect sense to me. I guess I will have to hang around for a few trillion years to find out the truth.

Answer 5

Antimatter galaxies populated with anti-stars producing anti-particles should populate half the known universe, according to the most popular interpretation of the Big Bang theory.

The Big Bang predicts that equal quantities of matter and antimatter should have been produced when the universe was created -- but nobody has ever detected signs of such huge amounts of antimatter.

Check out this article written. According to this NASA was going to test this theory and it should be done. Would be interesting to see what the results were

Answer 6

I believe that before the big bang was what there is now and time repeats in a cycle, and at the end of the universe every atom that exists will be sucked down black holes and in turn those black holes will be sucked in by bigger black holes till only one remains and when that happens it will colapse in on itself and since a black hole is a distortion in space and time it colapses and at that moment spills out all the energy and atoms and such and creates the big bang and then it all happens again.

Answer 7

Nobody knows, and we may never find out. Anything that happened before the big bang and therefore before the creation of the universe is irrelevant.

Answer 8

There was no "before". The univese also includes time as part of 4-dimensional space-time. I know this doesn't help.

Answer 9

a point infinitly small.
