does the universe have end?

I don't think so. Does earth have an end? Nope, not in 2D. So universe may not have an end in 3D, but can be multidimensional

The above answers are interesting but, modern physicists speak extensively about 'multiverses'.  So, does one universe end at the edge of another? or, do they 'co-exist' in space and time? OR??????

According to modern physics, yes. Any infinite universe would actually contain an infinite amount of data, and thus would be aware of its own existence as well.If, however, you define universe as 'infinite' or 'everything' then no.

the universe is finite yet has no boundaries. it may be something like the two dimensional surface of a sphere.  nothing inside or outside the sphere exists for the two dimensional surface.  nothing exists outside the universe in this model.

Many  astronomers think that the Universe is infinite. See, this\nwebsite for the complete explanations.

Universe theories talk about a finite and unlimited Universe. The Universe is unlimited because it has no boundaries. There is no edge, no end where a spaceship would have to stop. See it as a tiny bug walking on the surface of a big balloon. The ballon has a finite dimension, but the bug will never find the end, so it is unlimited from the bug's point of view.\nSo, the Universe can be expanding or contracting or staying the same size. This is a very important question to answer in modern astronomy. Latest studies say that it is expanding, but it has not been totally proved.\nAnd where it is expanding? The Universe is creating more space and time where there is nothing.

I believe the universe is a 'closed' shape, meaning that there is no 'edge', however it does have a finite size.  But just to entertain your question, if we one day did reach the End of the Universe we literally would be unable to describe anything on the otherside.  Everything we know about physics, space time, the fundamental forces, the universal constants and so on only exist in this universe.  Anything 'outside' of the universe could potentially then have different laws of physics and thus would be completely beyond our comprehension.  Words would literally fail.

There is nothing called the end of the Universe. There are three possibilities of the shape of the Universe.\n\nFirst, the Universe might have what we call positive curvature like a sphere. In this case, the Universe is called "closed" and it has a finite size but without a boundary, just like a baloon. In a closed Universe, you could, in principle, fly a spaceship far enough in one direction and get back to where you started from.\n\nThe second possibility is that the Universe is flat. This kind of Universe can be imagined by cutting out a piece of a baloon material and stretching it with your hands. The surface of the material is flat and not curved. You can expand and contract it by tugging on either end. Flat Universes are infinite in extent and have no boundaries.\n\nFinally, the Universe might be "open" or have negative curvature. Such Universes are also infinite in spatial extent and have no boundaries.\n\nThus whatever be the shape of the Universe, there is nothing called a boundary and hence nothing called the edge or end of the Universe.

No one anywhere has the answer to your question, or even if there was any "thing" before the Big Bang. The religious crackpot fundamnetalists certainly don't have the answer! By definition, the universe is everything there ever was, is now, or ever will be. At the instant of the Big Bang, all space-time and energy that will ever exist was created.\n\nGod is spelled B-I-G B-A-N-G\nPBrax@netscape.com

What lies beyond the edge of the universe is matter that is receding at a speed greater than that of light relative to us. Check out the Begy atomic model, It proposes that the big bang has no beggining and no end and is an ongoing process. Belief in God is possible, comprehension of God is not.

As you yourself suggested in an earlier question, "our" universe is finite, though there may be an unlimited amount of "bubble" universes out there, which we could not begin to have any specific knowledge of...\nEinstein's theory of relativity proved that time was a property of matter, and as matter expands at the speed of light into the omni-directional void, then whatever matter overtakes, there time also exists. In the void, there is no time. The edge of the universe, is where time began, but only for "our" universe...\nOur universe is roughly 20 Billion years old, our earth 4.6 Billion years...\n[From my 7th grade Science class lesson]\nBest question asked: Does the universe have an end?\nMy answer: Who knows!

To find out whether there is an end or an edge to the universe we first need to know what is the shape of the universe.\n\nMost astronomers would like to know the shape of the universe too! There are three general possibilities. First, like your balloon, the universe might have what we call positive curvature, like a sphere. In this case, which we call a "closed" universe, the universe would be finite in size but without a boundary, just like the balloon. In a closed universe, you could, in principle, fly a spaceship far enough in one direction and get back to where you started from. Closed universes are also closed in time: they eventually stop expanding, then contract in a "Big Crunch." All the geometry that is true on a sphere is also true in a closed unvierse: parallel lines eventually converge (e.g. longitude lines are parallel at the equator, but converge at the poles), large triangles have more than 180 degrees, etc.\n\nThe second possibility is that the universe is flat. This kind of universe you can imagine by cutting out a piece of your baloon material and stretching it with your hands. The surface of the material is flat, not curved, but you can expand and contract it by tugging on either end. Flat universes are infinite in spatial extent, and have no boundaries. Parallel lines are always parallel and triangles always have 180 degrees. Flat universes expand forever, but the expansion rate approaches zero.\n\nFinally, the universe might be "open," or have negative curvature. Such universes are sort of saddle-shaped. They are also infinite and unbounded. Parellel lines eventually diverge, and triangles have less than 180 degrees. Open universes expand forever, with the expansion rate never approaching zero.\n\nWhat determines the shape of the universe is its density (and the Cosmological Constant, a sort of anti-gravity force allowed by General Relativity). It is difficult to figure out what the density of the universe actually is, but it seems that the universe is probably flat.

As I understand it, the universe is in fact finite.  However, it's expansion is continuous and progresses at such a rate that we can not, with current technology, move beyond to see the end.

Recently, scientists are creating theories that saying there are more universes beyond our own. Until we learn to harnass the power of warpholes, black holes, etc. or send things traveling at the speed of light without damaging it, we may never know where space ends.

I hate to be the philosopher but that is why the question still reamins. No one can accuratly tell what lies beyond the boundries of the universe. Is there another? Is it just white noise? I believe that space is infinite and our "universe" could well be a part of a cluster of "multiverses". i was once told that the universe is expanding in the same way that a balloon is blown up. So what lies beyond our universe? I say space, space, and more space! \n\nIf our universe began with the "big bang" then that would mean that at some point the universe had collapsed upon itself, leaving empty space.

everything has an end

You get into Quantum Theory with your intrigue and there is no evidence to support that the universe is not infinate.\n\nHOWEVER, according to the Big Bang theory there was nothing and then there was something in a centralized location millions (billions) of years ago. At the speed that the universe is spreading outwards there has to be an end to it and scientists are trying to get telescopes powerful enough to see to the beginning of time.\n\nWhat lays on the other side? Nobody knows.
