3 days ago me and my friend thought up of the exact same theory. i was watching a show on tv that had to do with the universe and they were explaining the great distances between the nucleus of an atom and the electrons that move around it. then i started to think that matter as we know it, its just the building blocks for a larger universe(we are their atoms) if you were to look at our universe from far enough away, it would just look like a clump of light. well u can put that same theory to use when talking about ur computer screen, looks like a clump of light to me. dosent mean our universe is a computer screen in some other universe tho.
anywho, i was also thinking of the big bang thoery. apparently they think that a ball of matter, smaller than a golf ball, with all the matter in this universe, just blew up one day. well, in a larger universe, that little ball might have been an atom(or quark, ill get to that) of the larger universe. for all we know those "people" in the larger universe might have been splitting "atoms", hence, "the big bang". did u knno electrons arnt the smallest thing in the universe? if u take electrons, protons or nutrons and smash them togther at almost the speed of light, the E,P, or N will split up into 3 parts(for a fraction of a millisecond). these 3 parts are each called "quarks". in a smaller universe, the quark could be the recipe for a universe (ball of matter that explodes, "big bang") u might say that if we blew up a quark that we'd, in turn, destroy ourselves? not entirly tru cause the size of this new created universe would be much smaller than a golf ball in our universe.

this whole larger/smaller universe thing can go on forever both ways and eventually maybe both ends meet up somewhere but who knows...im only guessing and im prolly wrong, but its nice to think about :P


EDIT:ermitonto...i swear to "god" that i didnt read ur post b4 i posted mine...lol...kinda creepy how similar they were
