Do you think that there is an end to the universe? If so, why? If not, why not? Currently, it seems to be more likely that there is an end. Wouldn't there need to be an infinate amount of energy created in the bigbang to make an endless universe? If there was infinite energy, we would surely know of it (perhaps not exist because of it.) Also, why is the outward expansion of the universe slowing down. The question is, how can anything slow in an place with no friction or very low gravity(remember, as long as there is mass there is gravity). Could this mean a large mass at the center of the universe? Because objects 'sink' into space, this is entirely possible. Just sharing a little bit of deep thinking, which I do alot.
