if the universe is infinite what do you think is beyond the visable universe we see today?

More universe.\n\nWhat's the greatest number you can count to plus one?

Who can honestly tell you here? Our finite minds cannot begin to fathom the infinite workings of the universe. There could have been a countless number before us; 42; 3; or we could be it.\n\nWho knows?

how do you understand anything?  We can't understand everything there are things beyond our comprehension.  Try to think about this, does space end?  Is it infinte?  what is infinite?  You kno?

As far as we know, the only "wall" is the event horizon of the observable universe, the events beyond it from our point of observation are too far away to have their light reach us given the age of the universe. This "wall" of observation is approximately spherical (mod the local curvature) and is continually expanding at the speed of light. Every observation point in the universe has its own event horizon/observable universe.\nOtherwise, there is no evidence to think that the universe is anything but infinite. Recent observations of the cosmic microwave background give us information that the cosmology of the universe is flat, ie. planar. This does not tell us whether the universe is compact or not. The only other types of cosmologies that agreed with Einstein's equations were spherical and hyperbolic.\nFor more information, see the source.

Well, its been theorised that what is beyond the universe is a fourth dimensional bowl. Basically our universe is a 3d soup encased in a four dimensional bowl. How was that made? I would think the same way that our universe was created. I mean, we have only just begun to comprehend the world around us, many of the theories that are coming out are exactly that theories because we really dont know. Untill we can explore more of our universe, we arent really going to know, and if its in a 4th dimension, we really wont know. But, what you could do, is look at some of the sources, and hopefully those will help.

Nope, not what my theory says. My theory is as follows:\n\n"...the Universe as many see it, is expanding. Anything expanding must have boundaries. THus, boundaries can be anything holding something, in the Universe, the boundary is space, which is matter. Thus, anything inside something (or something finite) must be rotating."\n\nThe Universe my friend is not infinite, but finite with endless boundaries. It's like a ballon. As you blow air in the ballon, it expands, but there is no boundaries (pretend there is no plastic boundarys). But there is boundaries, because as you blow in the ballon, it is also expanding the boundary, (the air on the outside). The outside air is the boundary.\n\nThe Universe is much mroe complicated, unfortuanetly, but still with the same concept. It is also expanding, and as it expands, it also pushs it's boundary outward (the space outside of it). Space is matter! ANd therefore, the space, or the matter, is the boundary.

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.

possibly its infinite\nbut its an argument you will find quite interesting to discuss with REAL people. im no astronomer but a thirteen year old student.i can tell you that there is the M-theory which states of parallel universes.the string theory says that there is a 12th dimension which is outside the boundary of this universe. Now we ask what is beyond that? its hard to answer. But we should never let our Heads be larger than our Hats!

Universe in not infinite. It is finite and constantly expanding. Yes there are more galaxies than no. of grains of sands in all beaches of the world. This universe is unimaginably huge!

My opinion through many meditative thoughts:\n\nI believe our universe exists as a point in what you call 'the void'. A point having the geometric meaning of no volume, dimensionless.\n\nI believe what you are considering the void is what I call space. Our universe is what we can view, touch and explain through science we have developed. Space on the other hand is an infinitely dimensional medium, in which our universe was born. \n\nOur universe is nothing more than a 'disturbance' in space, and in space our universe exists as a point. This point is a fraction of infinity, yet everything is a fraction of infinity. So in the humble realization that we are nothing (a fraction of infinity), we realize we are equal to everything we can fathom, as it too is a fraction of infinity no matter how large.\n\nSo, through the realization that we are nothing comes the discovery that we can be equal to as much as we can fathom. \n\nI believe this means everything that makes up the universe and space has its own existence or presence known to space and must exist.  This existence holds true for our universe and what we would consider other universes. The disappearance, or non-existance of any defined object and its position in space no matter how small, down to a point, would truly have mind boggling consequences. \n\nIf time travel is possible than there must be alternate universes, as we know it.  It is a deadening thought to ponder.  Almost pointless until we figure out gravity, which I believe will open the door to all other understandings.

Size & volume of the current universe have little bearing on how "big" or "small" the singularity was at the moment this universe came into being, since the structures of the various sub-atomic particles that make up atoms and unltimately the "stuff" you have difficulty in "compacting" were not yet defined sufficiently for your question to have meaning.  Not that it's a bad question.  It's just in the same family as "well i know the Universe is infinite, but what's outside it?"\n\nStephen W.Hawking might be a good place to start.

The universe is an indefinite entity.It is bounded by 'nothing' even in the strict sense of modern physics.

The universe cannot have an end, it has to be infinite and completely symetrical. This leads to three possible scenarios for its shape a saddle shape, a spheroid, and a flat plane. Different experiments have led scientists to believe that space is an infintie flat plane. The main reason why we know that if there were edges to space then we would have to me moving towards some objects and away from others. This is not the case as all observed entities are moving away from us. This leads to the assumption of a infinite expanding universe. \n\nAs far as our perception is concerned we are not inside of anything since the universe occupies all of the space that we can observe so the universe is everything. But if somehow you could step out of our universe into a higher dimension you dont know what you would see. There are some theorists who believe our universe is one of many universe. But since there is no way to see out of the universe we may never be able to answer this question. I agree that if you start thinking in this manner it can get quite perplexing\n\nTo the person who said space must have an edge to expand think of a baloon. If we go down a dimension imagine that our galaxy is a penny glued on the surface of a baloon. To us the baloon has no edges at all since we cannot see out into the third dimension, yet the baloon is expanding. So from our vantage point we live on an infinite surface that is expanding and causing nearby pennies to all travel away from us.

Yes this is a hard topic to understand the only way I can explain it is to imagine that space "curves" onto itself. Thus is finite.\n\nThe reality is an actual infinity can not exist, its something conceptual, impossible lack understanding of what an actual infinity is, it can exist mathematically as an Ideal, but not in reality as that is physically impossible.\n\nLook at the attributes of infinity:\n\n(1) You can not add to infinity\n(2) Any part of infinity is the same as the entire "set"\n\nWhen we trace our Universe back to the big bang we end up with a singularity, this is where "Science and physics break down" it can not be really explained and we have to go to a higher source of knowledge i.e. theology.\n\nWhat I will end on is saying that one of the Attributes of the Creator is that he is infinite.\n\nI hope that helps\n\nAnhar Hussain Miah

What we consider the physical universe is limited by physical laws. The universe that we can comprehend beyond those laws has limits that we can not comprehend. One such limit is the speed of light if matter in the universe exceeds the speed of light relative to our observation point it will pass out of existence as far as we can detect. A black hole is another such limit to our universe, infinite time, distance etc. The Begy concept of gravity(a substatement in the atomic model) describes a big bang which has no beginning and no end, infinite energy. which we can only detect as the force of gravity. Hey theres another limit!

Sorry, as Braxton points out, the size to the edge of the observable universe is 78 billion light years due to the expansion of the universe (same source as the other guy used, Wikipedia) There is much debate as to whether or not the universe is infinite, but many scientists believe that the universe is indeed finite in size.\n\nBY THE WAY: I find it comically amusing how two people can cite the same source, yet somehow I'm the wrong one.  Oh well ;)

My Astronomy teacher at college of the redwoods believes it not to be the like a big ball though, it may be in some way like that.  He believes it is more like a blob of water in zero gravity.  It isnt a circle but it has i would say lumps in the ball type figure.  All of this but on a much larger scale.\n\nBy the way the universe is not infinite but it is expanding.  It may be huge but we believe to have found areas that just return no data.  It is about 560 billion light years away from us.  It is illogical to even believe anything physical to be infinate.
