Look... i have theories how the universe works. At one time we were a solid ball of condensed matter. This matter some how exploded creating the universe. The universe as we know is still expanding but in time it will stop. Suns will burn out and become black holes sucking everything back into the center. As the unvierse shrinks IN THEORY time is suppose to go backwards. We will condense into a solid ball of mass and explode once again. What i don't understnad is the lost matter that occurs in a nuclear explosion. Where does it go?
