Take space for example. It is vast, but it contains absolutly nothing.

It is an incorrect concept that space is full of nothing.  There are dust particles and gas molecules in space.  The solar wind from our sun is always blowing particles into space.  There is also a galactic wind that is blowing particles out into space as well.\n\nSpace is as close as we can get to natural vacuum, or nothingness but it still has a density of one atom per cubic meter.

In spite of what some yo-yo answered, the universe IS expanding, but whether or not it's expanding inside something else is absolutely and totally unknown. In the far distant future our science might have progressed to a point where we'll have the means to answer that question. Instead of driving yourself goofy over wondering what our universe is inside of, best to just try and imagine an absolute and infinite void totally without space, time, energy, mass, or anything else.

There are no such things like nothing. Nothing is a human defentition of emptyness. Existence of nothing is already existence of something. The smallest part we know something like proton and photon but that what we know. I am sure there are even smaller parts that in time will discover.

there are stars out there that haven't been discovered yet.  There is a finite amount of atoms in a grain of sand.  The period at the end of this sentence can hold about 250,000 atoms across.  So a grain of sand would have less atoms than there are stars in the universe.

It has width, depth and length. However it does not have time. because it has no mass. Empty space is certainly something but it has and probably will be a paradox for a long long time. At one time the "fabric" of space was reffered to as the "ether" as in ethereal, but even this ascribes to much "material" to empty space.

Aint enuff space here! Tons of reasons! If you are having trouble add details.

there is no dimension to the universe, its infinite. the horizon never ends either it keeps moving with you. its around 25 miles away depending on where you are. Its as far as you can see because of the curvature of the earth.

do u mean universe in universe we have space where it is absent in the egg

In all actuality, your question makes no sense.  If you were to take out all the "space" in matter, there would be no matter.  Matter is basically made out of energy and forces interacting with each other.  If you compressed the universe into the size of a refrigerator, you wouldn't have matter anymore.

As far as I know, there are only 2 real-life examples of such a process: the Big Bang and a black hole.\n\nThe Big Bang caused 'everything' to expand into 'nothing'. That in itself is an infinitely large expansion; it's like dividing infinity by 1.\n\nA black hole is, in essence, where matter collapses to zero size, thus reaching infinite density and creating a hole in space-time. Little is known about the interior of such black holes, or, indeed, if there is such a concept.

The concept (that's what this really is) of nothing - or "no thing" is easy to understand and explain its existence. Lets examine a few things to get a grasp of this.\n\nFor example, when there is a lack of water, we say that its state of being is dry, arid, etc. Simply because there is a lack of something doesn't mean it does not exist.\n\nMy second example is that of your self. If you are not in a specific location at a specific time, and I am a witness to that event - or lack thereof - does that mean you do not exist? Surely not.\n\nFinally, the concept of "no thing" goes one step further than the examples above, however it is important to remember that the state of being no thing is exactly that - a state of being. Can something that does not even exist have a state of being (or a state of not being in this case)? It must exist to have these attributes. Simply because some thing does not have tangibility in our physical realm does not mean it does not exist. In fact, I would argue that due to all of the things I've stated here, it is more likely that the things we can not see or grasp are more likely to be real in a truer sense than the things we see, hear, touch, smell, and taste everyday. Simply because it is a concept does not mean it can not exist.

space is not a fluid that planets need to float in it is just plain emptiness.

If the universe is infinite, it doesn't mean that everywhere is the center, it means that it has no center. Or, if you mean relative to the existing matter...well, that isn't infinite, and has a defined center.

I think you are confusing homogenous with constant. The fact that the universe consists of packs of matter separated by tremendous amounts of empty space makes it exactly inhomogeneous! However, because of conservation of energy, there is a constant interrelationship to the universe.

Hi there,\n\nTry looking for "Klein space" (without the 's). You get for instance this page : http://www.mccallie.org/myates/The%20Shape%20of%20Space/Student%20Projects/group10.htm

Outer space is not nothing. Even without the presence of matter, it is teeming with quantum foam, particle-antiparticle pairs, space, and time. For all we know, spacetime may not exist outside our universe."\nAlso, the universe may not be bounded. The only way to "exit" may be to find a "fourth direction". Ie., think of a point in an unbounded plane. The only way for the point to exit its universe is to somehow find the "third direction".

Remember the fact that what they say( that outside our universe is the void, which is absolutely nothing, NO SPACE OR AREA) is only a strongly held VIEW, or CONCEPTION. As far is science is concerned, there is no evidence that there is " no matter beyond the area within which the universe is existing ".\n             Suppose you have balloon. Imagine it to be the universe, then, people living inside the balloon, cannot acually guess about the fact there is no matter beyond the balloon, unless and until they are being confronted with the FATE of the ballon. Remember that the universe is like a balloon, continously expanding, so, there is a high possiblity that it might all actually begin to compress after some billion years or something. \n            What I meant to say is that, there is no solid method to find out about the matter beyong the universe, as the FATE of universe alone will answer these questions. OR, there is a lot of matter beyond the universe, just as air beyond the balloon, may be the expansion of the UNIVERSE would NOT allow us to determine whether or not, ther is matter beyond the universe, as for now, we cannot say anything.\n          Hence, what I have said above is also a conception, a theory, a prediction, which MAY be TRUE.\n\nDa Vinci.
