    ive heard a lot of theories about the universe such as

    the universe is purely infinite
    the universe is expanding and is one day gonna be regressing

    but i tough about it
    matter when expanded too much just loose its ''shape'' it crumbles, like a sheet of paper you woudl wrip appart

    so if the universe as a mass and expand even if it is ''infinitly'' (more like uncalculable by human) dense will one day wrip apart

    what ya think ?

    I think it is the space between matter that is expanding, not the matter itself. So I don't think there is any danger that the universe will eventually rip apart.

    well thats what i meant the space between mollecules stretche's so much that it will eventually rip apart because there is not enough energy between them to keep them bound together, because as the universe expand this energy gets balanced between them so it can stay like it is, but eventually they will be too far away from one another.

    thats about it

    I guess it's theoretically possible for the expansion rate to accelerate to the point where it overpowers first gravity, then the other 3 forces until matter is literally ripped apart.

    However, I haven't heard anything about this. By comparison, I've heard a great deal about the heat death of the universe. Which is when all the energy is "spread out" and no useful work can be done. Which leads me to believe that this form of universal death will happen first.

    Assuming that the universal expansion's acceleration will continue, that is. The "why" of the acceleration is still something of an unknown (calling it "dark energy" doesn't mean it's any less unknown).

    It is called the Big Rip, in reminiscence to the Big Bang.

    Always assuming that the universe is expanding. A number of serious problems need answering to back up that idea.

    Assuming that expansion has increased according to dogma, it could mean that galaxies and clusters that we now see as stable under the present higher level of expansion could have been collapsing under the previous lower level of expansion.

    Hi
    That could be the point were the universe starts to regress.
    but i suppose if the molocules are being pulled apart then that might actualy creat more energy.
