that's the beauty of quatuum mechanics - things don't always follow the logic of the world as we know it. Something can be in two places at once in the quantuum world.
So nothing can be something, and perhaps quantuum theorists will soon discover the maths that will explain how the multiverse (string theorists believe there is not just one universe but many on different dimensions) can come into existence from "nothing".
I expect things such as "zero point" energy and perpetual motion will be discovered not long after.

@masseur,what the universe is expanding into is still unknown...and neither is it's shape..but it must be remembered that the universe isn't actually the universe..there maybe SOME material or object beyond it..

I guess the point of that question is that the universe is supposed to include everything that exists in time and space and therefore any material that exists outside the universe must, by definition, actually be within the universe.
of course this question is a paradox because if the universe is expanding its logical to conclude that it is expanding into something, but if there is something to expand into then, again by definition, the universe must be including that which it is said to be expanding into
also, I guess it comes down to what the actual definition is for universe if it is not as I said earlier, everything in time and space... is there some border that encompasses it such that everything outside that, and which possibly obeys different laws of physics, is not included?
hmmm...

(yep,but mentally,logically,technically,physically and physiologically,there is a limit..but the universe is far beyond it.There's on one thing between that limit and the country borders of the universe.As the topic says,there is this time machine thing but I think that we may go to the future OR the past..but don't think we will.As the universe is expanding,the thing outside,may,according to my notebook,come inside the universe.{note..please,I'm giving this info but don't use it for any commercial purposes.Also don't copy and paste this.So it's copyrighted until the universe ends by my notebook.}Because of the fact that matter cannot reduce to it's half by pressure,it has to come inside which I think will cause another big bang.COPYRIGHTED.)

Ok..1 minute gone since you started readin this post.Wow!Great speed..not of reading..you've moved 4500miles from where you were last time! Ok..Again I don't have a

we need also define "inside" and "outside". Maybe other dimensions are contained "within" this dimension via some quantuum effect (string theory for example), which would allow for nothing to exist outside the universe, but for the universe to still not be all that exists. In this case "outside" as we understand it, because of time and space curvature, may not exist. There may be nothing "outside" the universe, and it may be expanding without anything to expand into (as the universe expands space/time expands with it). In such a case, there is literally nothing outside the universe, in such a case it would be impossible to exit this universe. If we flew through space to the end of the universe we would just end up where we started.
However if we assume there are other dimensions (besides the three dimensions of volume and the fourth dimension of time that we know of) then we may be able to find a way to leave this dimension to enter parallel dimensions. These other dimensions may be infinite in number (like there are infinite numbers of single points along a finite line).
Therefore it's possible that "all that is" (being the universe we know and all parallel dimensions we don't know about), could be both finite, and infinite both at the same time.
In such a case, to go "outside" the universe that we know, we really have to side-step into other dimensions. Another result of this scenario, is that eventually if humans survive long enough, we will have explored all the universe that we know today. Like Columbus discovered, you could not reach the end of the earth and fall off, because the earth is a ball.
We may discover the universe is like the Earth and that we can't leave it without entering a new dimension, just as the two dimensions that early sailor's travelled (north/south and east/west) were not enough for them to leave the earth altogether. To leave the earth we had to travel in 3 dimensions.
If the analogy follows, learning to travel in time (the fourth dimension) may allow us to leave this universe and to discover other worlds that we will never know exist while we attempt to expore the three dimensions of space that we have ready access to.
As for the expansion of the universe, if the universe is infact folding (in three dimensons not two), then more space could be created without the overall size of the universe increasing. Think for example if the surface of the earth expanded without the globe getting any bigger. What would happen is the surface of the earth would fold up with mountain ranges popping up everywhere. The folds increase the surface area of the planet without increasing it's over all size. This may be what is happening with the expansion of the universe, yet another possible explanation for how the universe might expand without it actually expanding into something.
Also, the inhabitants of the universe who live in three dimensions, would not be aware of the folding unless they could travel in the forth dimension. (much like we are unware of the curvature of the planet's surface unless we fly into space ie: travel in the third dimension)

can someone explain what is string theory??

Very basically, string theory is a branch of theoretical physics which attempts to explain the behavior of subatomic particles and physical processes, such as the exact mechanism behind gravity for example.
In string theories (there's more than one!) the universe is made up of "strings" which are moving through space and are under tension, rather like a guitar string. If the tension of the guitar string changes, so does the musical note that it produces.
String theory dictates that particles are like notes, so a particle can be thought of as being "caused" by a string being at a certain tension at any one time.
But that's just the beginning. String theory, unlike some other branches of particle physics, allows for strings to exist in more than the four dimensions that we are familiar with and it uses this idea to try to explain some of the stranger things we see in particle accelerators that cannot be fully explained with 'traditional' quantum mechanics.
It's not an alternative to quantum mechanics, it's more of an extension!

in short, string theory can be a great candidate in formulaing the TOE (theory of everything)...?

Yes, I guess it is really. It's certainly looking like being a step in the right direction.
