if you think the universe ends, what is beyond the universe?

Some astronomists believe that once you leave one boundary of the universe, you re-enter through the other side, like a giant Pacman game.

The universe ends when your mind stops searching for it, but will never end if you continue to persue it.

There's The Universe, then there's the observable universe. No one knows the size of the first one; it's probably infinite. The second one is the universe with a boundary; that boundary is how far we can see into The Universe, about 13.7-billion light years.

yups thats something even i was wondering for quite some time, but then i thought like on earth , its so big seems to be endless\n\nbut then the end you think has a wall and even a wall has another side to it, there surelyis  something on the other side\n\nso for sure we never wou;ld be able to describe it but surely the universe the galaxy is endless\n\nso keep your thinking hat on and just start this journey of imagination of what all could be there.....................a sun,,,,,,,,,,ocean,.,...........aliens with PS1001..........................or an church for an alein god.................

The universe has no discernible edge, but neither is it infinitely large.\n\nThis is because the universe has non-euclidian geometry.\nEssentially this means that parallel lines will meet at infinity. Crazy huh?\nIf you keep going in a straight line long enough you will eventually come back to your starting point.\nThink of it as if the universe is a balloon. If you walk in a straight line along the balloon's surface, you will travel all the way around the balloon and come back to your starting point. Then just imagine that the balloon is expanding.\nThe balloon (our universe) gets bigger. But with the universe, it is not expanding INTO anything.\n\nAre you an advanced physics student?\nIf so, read about Einstein's Theory of General Relativity (With loads of lovely maths :) ) to gain more insight.

if we say its size is limited . then what will be beyond the universe . and if we say its size is unlimited . then how can we explain this . the space and the time are very difficult to understand . that is why some says that the only thing real is GOD . the whole other things are only an imagined thing created by GOD . like a dream . but you must know that even the dreams have some being of some kind . if a dream is not exist . then how can we see it .

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.

Which is the end of expanding universe? If any end exists, what will be behind this end?\n\nBefore we can address that question, we must first define universe.  \n\nThe word universe denotes all space and everything (matter, energy) contained within it.  The prefix uni means one.  The root verse means word, carnate message, meaningful substance, matter.  Questions regarding our universe persist today.  Does it have a beginning and end, or does it go on forever and ever?  Is it linear or curved?  If it has limits of length or curvature, then what lies beyond the Universe?  If something lies beyond the Universe, then can’t we accurately call that the Universe?\n\nSome lay people and some scientists conceive of the universe as infinite space.  Others define the universe as finite, or limited (perhaps curved), space.  Still others incorporate the elements of matter and/or energy into their definition of the universe, as opposed to the space beyond matter and energy.\n\nGiven these concepts of our universe, some scientists conclude that the “totality of space could be infinite. Shrink an infinite space by an arbitrary amount, and it is still infinite. (Scientific American March 2005).”  \n\nAs to the notion that we live in an ever expanding universe, moving away from every other universe on the fabric of space-time, some scientists are careful to point out that “\n\nAndromeda, our nearest large galactic neighbor, is actually moving toward us, not away. Such exceptions arise because Hubble's law describes only the average behavior of galaxies (Scientific American March 2005).”\n\nIn accordance with your supposition that our universe is in another universe, “it has been hypothesized by some scientists that the universe may be part of a system of many other universes, known as the multiverse (http://en.wikipedia.org/wiki/Universe).” Modern astrophysicists talk about multiple "pocket" universes that branch off from one another.  Stephen Hawking points out that parallel pocket universes can have no effect on a real observer inside a single pocket, so, according to Hawking, they are theoretical baggage that should be eliminated from cosmology, the study of the origins of the universe.\n\nSome string theories define the universe as a three-dimensional space in an invisible space having more dimensions. This is, in essence, a universe within a universe.  Our zone, a “braneworld” could periodically bounce into another parallel braneworld.  \n\nThis may create what would appear as a Big Bang from one perspective or a Big Bounce of alternating expanding and contracting universe from another perspective.  Such a cataclysmic event is thought to occur 300 billion years from now, resulting in the rearranging and creation of a new universe.\n\nWhich is the end of expanding universe? That may be determined in 300 billion years, when it stops expanding (like a balloon).  If any end exists, what will be behind this end?  A multiverse void containing other expanding and contracting balloons, referred to as universes, may exist beyond our own.\n\nSteve\n:-D

It does not end and its growing, before you try tackling such a question, answer the micro-level questions of the same kind.  The universe encompasses all that exists, and by default then, it is largely unknown.  We don't know where the universe ends, and all evidence points to it being endless and growing, therefore we make a conclusion based on a portion of the information actually needed.

Once you leave the Milky Way you are not outside the universe. The Milky Way Galaxy is one of many known galaxies in the universe. There are probably billions we don't know about. "Goodness knows where" is inter-galactic space.\n\nInfinity means "forever". It is not necessarily a measurable distance or time. We're not sure if the whole universe is infinite. We can't even see most of what is out there. The estimated size of the observable universe is 7.4x10^26m (that's really, really, really, really big). Beyond that we're not sure yet.

Actually this will be unknown forever cause by that time the universe will reach to its "ultimate fate"\nby the way, you can go here to know...\nhttp://en.wikipedia.org/wiki/Ultimate_fate_of_the_universe

infinity and beyond . . .DUN DuN dun . . ..

Hard one to understand. but it's something like this:\nIt is said that if you go to the end of the know universe.\nAs you keep going you create space.\nThat nothing before you got there existed.\nSo as the universe expanse it creates it's self, space.

yes i do.  it begs the question...so where is the edge of the universe...and what does it look like?  is it moving further outward or just hanging out like a big wall?  very deep.

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.

Probably find a ship graveyard.\n\nNo...for real...I don't think it is possible to reach the edge of the universe.\n\nPrint this out, then if it happens, you can say, "I told you so."  :)
