    it gets you thinking..... is there a end to the universe? does it loop like a doughnut shap theory?, whats outside the universe if anything..... is it possible the universe cannot end?
    are their differnt dimentions? parrale worlds....
    Oh! will man ever discover the facts of the universe!


    what do you think?!

    We could reach other Universe,that is at other Dimension with the help of Artificial Blackholes Vehicles etc.I dont know whats the end of the Universe.I heard that Universe is Flat.And Flat is just a part of a Circle...so possibilities are Infinite...



    bye!

    I think that you've gotta breach our dimension somehow, because if you just fly around in a rocket ship you'll go around in circles no matter how far you fly.

    if youd go in circles, then the universe would be a bubble, so its plausable that theres something outside this "bubble"?? but what if anything?

    Yes, but it's safe to say that anything beyond four dimensions is somewhat beyond our comprehension. We're in the shape of a bubble, but only the outside skin of the bubble itself.

    Can we reach the end of the universe

    From apolo
    Reply to" A CANADIAN" My short answer is no.
    Personaly I tend to agree with Fred Hoyle, G. Burbidgr, V.Narlikar,
    Halten Arp and others, that the universe is infinite in both time and
    dimention. In other words it was never created and it will never die.
    It is infinitely large. All the things we observe including the 2.73
    degree background radiation can be explaned if we start with the asumtion of an infinite universe instead of a Big Bang.
    As a bonus we avoid those nasty question; What came before the B.B.
    and What caused it.

    I kinda always thought the universe was like one of the old ATARI games where if you went all the way to the right end of the screen you would just pop right back up on the left.

    Thats the only thing I can think of happening. Personaly i dont think the universe has an end. It doesnt have a begining so how can it have an end?

    If you think about it, this galaxy could just be an atom on some guys head!

    But thats out of the box thinkin.....

    When I think about this kind of stuff, I start screaming. Its too amazing.

    If there was no source of light, would the universe exist?

    Whatif we are just making up the universe as we go along.

    Or what if the universe is making us up as it goes along.?

    By the time we get there it will have moved.

    Let's say the "end of the universe" is 15 billion light years from here. (For the sake of argument. If any of you has the correct figure, feel free to plug it in.) Let's also say we have spacecraft that can travel close enough to the speed of light that the difference is not large enough to affect the answer to this question.

    Therefore, it will take a human spacecraft 15 billion years to reach the end of the universe -- whoops, the place where the universe ends today, which will be 15 billion years in the past for the crew of the ship.

    How much would the universe have grown during that time? The matter could not be expanding as fast as our ship can travel so we might eventually run off the edge of the mappable universe into the empty space beyond, but that space will still be full of light rays and other EM radiation traveling at the speed of light from the bodies inside the populated universe.

    No matter how far we go, the light from the universe is still ahead of us.

    First the universe can not be infinite...
    infinite # of stars=infinite amount of light=always daytime
    You have the same problem if you say "we can not reach the end because we'd go in a loop". If you go in a loop then light would too, which would cause the same problem.

    some theories predict the the universe is finely tuned so that it will expand forever...( therefore infinite space)...

    if it is closed then it will be finite ( and slowly contract to a big crunch)

    if it is open then it will still expand forever....

    Its reffereing to a universe which is full... where you can go how every far you want, and there are always stars infront and behind you.

    Its a simplification of Carl Sagan's idea... but basically:
    Stars give off light
    Light travels forever until absorbed
    Every direction you look there will be a star... because the number of stars are infinite
    Every direction will have the light of a star


    This does not say that space is finite, but that FILLED space is finite

    -hmmm. i like that.
    my bet is that the universe is some kids science experiment. we're all in a sphere on some kids lab table. wouldn't that be great

    Here is a link to some info saying the universe might be similar to a hypersphere. This object has no boundries, sounds promising.

    Thanks for the link Tallguy.

    I've also seen theories that the universe expands as mass does, so the instant you go to the end of the universe, the boundary goes out further. In essence this is the same as having an infinite universe with finite mass... because there is no way to tell the difference.

    It seems to me, as you get further toward the "edge" of the universe, there would be less and less light. Like stars, and other celestial bodies would not have had a chance to be formed. Sounds kinda creepy to me.
