i dont if this should go under science or what, so i posted it here, its a bit theological, scientific, and philisophical... which accounts for my confusion. my girlfriend and i were debating whether or not the universe will expand forever, or collapse again under its own gravitational force (crunch). she said it would crunch and keep expanding and contracting for infinity. she made the argument that since life existing is such a small chance, then it may take close to a million universes to have the chances of it occur. finally, we are alive after a few trillion universes, and we are perceiving the universe we are in until it crunches again. i said the universe was linear, rather than circle-like. i believe that a divine being banged the universe out in a certain order to allow for life to occur. also, i dont think that the universe will crunch. if gravity hasnt slowed the universe down yet, it will keep expanding forever. wutcha think?
