    I dont understand were the empty space that our universe is inside of ends?
    I assume that if you were to cross the edge of our universe there would be more empty space (or) space with something in it.
    So here are my question's.
    The area (or) space that our universe is inside of, were does it end ?
    How can a space (or) area be infinite ?
    And if this space (or) area is like a worm hole or some thing, what is beyond that, and were does that end?
    It just seems strange that the area that our universe is located inside of can go on forever.

    Universe literally means everything there is.

    So give us your reasoning and thought process ...
    What makes you think there is anything outside or beyond it ??

    Maybe I am wrong, but I consider the end of our universe, to be the edges of the galaxys that are on the outside of our universe, moving into a empty space.
    I have heard scientists say that some galaxys in our universe are moving in a diferent direction. Some scientists assume these gallaxys are being pulled by gravity, from some great mass, that is outside of our universe. Maybe this great mass could be a another universe (or) a huge black hole.
    They say our universe started from a huge explosion and it is moving outward. It would seem to me that, as our universe expands, it is moving into a space that is already there. Maybe that space that our universe is expanding into has no matter in it, but I think that space is still there.
    I just assume that there is a very large area outside of our universe that the outer galaxys (of our universe are moving into as you read this.)
    Maybe I am wrong, but I consider the end of our universe, to be the edges of the galaxys that are on the outside of our universe, moving into a empty space.
    I would call the space that our expanding universe has not gotton to yet, the space outside of our universe.
    And my question would be, the space that our universe is expanding into, were does it end , how could it end, and what is beyond that ?
    It just seems strange to me that this space could go on forever. But if that space ended there would have to be something beyond that.
    Some scientists believe that if you went outside the bounds of our universe, you would end up, re-entering our universe from the opposite side, but I just dont feel this. To come out the opposite side of the universe, you would have to instantly be traveling a area (billions) of light years away.
    I see our universe as a balloon, before the big bang this balloon had no air in it , after the big bang happened this balloon started to fill up with air, and expanded and got bigger , just like our universe. And before this balloon began to expand there was space around it.
    Were does this space end ? how can something go on forever ? but still how could it end, because there would have to be something beyond that.
    I see our universe as a bunch of pool balls on a pool table, all moving away from each other, I dont see how if you passed by a pool ball on the outskirts of the table you would instantly end up on the opposite side. I see our universe as a expanding balloon, how could matter instantly be transfered to the opposite side apon exiting ???
    The space that our universe is expanding into, were does it end ?
    But still how could it end, because there would have to be something beyond that ?
    Even if (everything) was in some kind of circular wormhole there would still be something outside of that.
    I have always thought that our universe was very large, but the area that our outermost gallaxys are moving into must be really big ?
    were does it end ???????? I dont know were , or even if it does , but it must be big.

    So you are saying there is a universe 'outside' the universe ???
    Are they not the same ?? And since the whole universe is expanding, wouldn' the universe outside the universe also be expanding ??

    No. The whole universe, everything there is, is expanding. And not into something else. There is no outside althoigh there is an outside to the observable univers ( due to the finite speed of light we'll never see that part out side the observable universe, but it cannot affect us either ).

    What if the universe goes on forever, ie is infinite ??
    What if the universe curves back on itself , ie is finite but unbounded ( but still no outside ) ??

    The 'outside' of the universe could not be reached unless you travel at multiples of c. in a thought experiment you might derive the 'edge' to be total darkness.unless its a multiverse,then you may see another universe at the outside.hypothetically off course..no one knows...yet

    You are correct, this is one of the most important questions in the human experience. One's whole life can be altered by considering the ramifications. The current understanding of the history of our Universe is what is called the Big Bang theory. In short, a singularity began expanding roughly 14.7 billion years ago – give or take a couple eons.

    The singularity did not exist in space and expand into space, but space was within the singularity. In fact, we – the entire Universe – is still within the singularity. Which is to say, there is no ‘outside’ to the Universe. There wasn’t before it expanded, and there isn’t now. Not in any sense we can discern or comprehend, anyway.

    Nothing ‘exploded’. The singularity expanded and continues to expand. In fact, it’s expanding at an ever increasing rate and no one knows why. Nor did the singularity expand into something. There’s nothing without the Universe expanding. In that sense, the expansion 'generates' space.

    There is no ‘edge’ to the Universe. There is no place one can look ‘outside’. You are as close to the ‘edge’ of the Universe right where you are right now as anywhere else is.
    Under current understanding, the Universe is not infinite. Since it was a singularity and expanded from essentially no size at all, and now continues to grow, it is a finite size. Which is not to say it isn’t mind-bogglingly, knee-wobbling, baying at the moon huge.

    Under current understanding, the Universe is curved in on itself. Like the surface of a sphere (like a cue ball in pool) the surface is curved on itself. If you place a magic marker on the surface of the cue ball, you could draw a line forever, but it would end up crossing itself. Still, as long as you hold the tip of the marker on the surface of the ball, there are no edges.

    Okay, there are some other theories about the structure of the Universe. The primary alternate is the Multiverse concept. This postulates our Universe is one of an infinite number of similar Universes floating loosely in a holding container called the Megaverse. Instead of a finite beginning and a finite ending, the Multiverse has always existed and will always exist, because when any one Universe runs down, another bangs into it and charges it up again. This is superior to a single Universe existing for a finite amount of time for reasons I do not comprehend. Except without a beginning and ending, we can dispense with that problematic ‘God’ person.

    You need to do some reading on the subject if you wish to get a better grasp. Go to your local library – public or school or both – and check out their science-astronomy-cosmology-physics section. Start at one end and read to the other end. Read the older stuff first. One gets a better idea of how the perspective and general attitude changes on the subject. Especially read Einstein’s work on Space-Time. Read about the Big Bang first and then the attempts to discredit it; that’s more accurate chronologically and makes more sense in one’s head.

    And good luck.

    The universe is a real place. However, you can't see it, you have to imagine it. Like it or not, God designed, built and sustains the Universe. Deal with it.

    That is the dictionary meaning of universe yes. However, the universe had a beginning, call it E.oS or the big bang......it had a beginning, and if it had a beginning then there was a time when there was nothing at all.....does that make any sense? nope......

    Look up "Multiverse theory" - I do not think this is mainstream science but I think this is more plausible than the "something from nothing" idea.

    There has to come a point, where you do have to except the idea that all mathematicians hate - infinity. If the universe was "always here" - then great there does not need to be anything before the BB, but we know otherwise, so to find the infinity of substance, one needs to travel beyond the realms of our known universe.
    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.

    You say "there was a time when there was nothing at all" but I understood time did not exist and was created, along with space and matter, in the BB.
    I agree that the idea of something from nothing goes against all common sense notions, but I don't see how the Multiverse concept avoids that issue. There still has to be a beginning!
    Lastly, I don't understand what you mean by "the infinity of substance".

    I would suppose that the universe has no true limit or end, if everything in it is some form of matter and this matter is expanding then as anything in it moves then the whole of it grows ever more, much like having a tank of water filled to the brim then inserting into a basket ball and the water if able will just reach a new level, perhaps space with its Dark Matter and observerable matter just continuelly grows.
