I have read that from an arbitary central point, as in the Big Bang theory, whole Galaxies ,on the very limit of our percepcion, are in fact receding at close to light speed after accellerating outwards since the universe began, as mass would become infinite,how could it be possible for any increase in velocity to occur?

Do you think people in unpopulated areas would be able to hear it? Would it cause everyone who heard it to go deaf?This is assuming that everyone is outside when they scream, and that they scream at the top of their lungs.It would have a lot of dogs howling at the very least,and that would cause even more noise!I wonder what would happen.What do you think?

Let us assume for a moment that the universe we live in is finite, it means everything we could learn about anything is found within the boundary of our universe therefore knowledege itself is finite. What do you think will happen to us if someday (it could be thousand to milliion years from now) there's no more question to ask, there's no mystery to solve and total understanding of everything is achieved. Can you picture what kind of society the mankind will have?
