Everything that starts must end somehere.We know that universe started with a big bang.Then what existed before BigBang.
Everything needw a volume for expansion.Since, universe is expanding..it means its occupying a part of volume in a bigger volume.So what does that bigger volume contains?Where does it all ends?

Hey , this is where a layman is wrong , the universe is not expanding inside space , but the big bang implies an expansion of space itself.
The universe is not expanding inside space , rather space is a property within the universe not outside it.
hmmm , reading Hawkings' book , "A brief history of time" might help you to form new ideas on the way one can perceive the notion of space and time.
As to the question , what is beyond the universe ; that is a tough question indeed.
However , if you would accept a theory that space is "folded" upon itself and hence is curved in 3 dimensions then there is no edge of the universe implied .

I am really surprised by the fact how many people here on yahoo ask for the "beyond" the universe ....
First of all, we do NOT know that the universe started from a big bang. This is just the most comprehensible theory, but we do not know it. There is no evidence.
And, now assuming there is really and end to the universe as we know it, then we wouldn't know what is beyond, for4 we don't have a definition for what would be behind a borderline we don't know.
Besides, you're talking of "volume". Our volume is defined by 3 dimensions: length, width, and height. What if the "bigger thing" around the universe was made of 11 dimensions? Or less or more? Then your (our) definition of volume isn't valid any more, so you cannot say, the universe is expanding into a volume of something else. That way you are creating an error, a syntax error.

"Everything that starts must end somewhere." You are only assuming that this is true, it does not have to be and you cannot prove it one way or the other.
There is no reason to believe that the universe started with the big bang, the big bang may just be one event with things happening both before and after.
The expansion of the universe is not an expansion as we might usually think of it, it is just that the distance between things is getting greater. The usual way to explain it is to think of a balloon. The thing is though, that we need to think of just the surface of the balloon and a 2D world, and think from the point of view of a 2D creature living on the surface of the balloon. Here we see the distance between points getting larger but the 2D world is not expanding into anything.

Think of the universe as the two-dimensional surface of a balloon. On that balloon, if you were a flat creature, there would be no end. It would be a "closed universe". Now, mathematically it is possible to describe this balloon situation without there being even any third dimension in which the balloon is sitting. This is kind of like the way physicists understand the universe. ...except that the universe is is a three-dimensional closed universe, not two-dimensional.

I imagine that the universe is "expanding" like a balloon that will never bust. But I beleive that if you travel to the end of the universe and continue on (assuming you are travelling faster than the rate of the universes expansion) that you will end up at the other end of the universe. Imagine that the universe is a cube and if you travelled through the right of the cube you continue on through the left side of the cube. Make sense?

According to the Big Bang Theory, it is not expanding into space. As it expands, the universe IS expanding.

Round. seems to be the main shape in the universe..( kind off ) Planets , moons , solar systems .
I think that the end of this universe brings us back to where we were...I don't think its a flat expanse that goes on forever.. And I don't think there is only one.. From out side our sphere universe there are other universe .. its the space between them that gets me.. Whats there.. ! Dead space. !

apparently, our universe is on a membrane. we see 4 dimensions which appear infinite. There are 11 dimensions, 7 we cant see, and there are other membranes with other universes on them beside us - think of a loaf of bread, and we are on one slice.
reference Ed Witten, CERN LHC, M theory, Stringy Universe, and
you will find that all old theories are out the door...

If you could get outside of the Universe the area there wouldn't have to behave the laws of physics, so it is beyond our comprehension at this point.

Hi. I think the universe would look the same if you got to the "edge" and looked further.
