(See pictures of the world's most polluted places.) It would provide an inexhaustible supply of energy, without pollution or global warming. I would like nuclear fusion to become a practical power source. Which scientific discovery or advance would you like to see in your lifetime? Einstein was aware of this but somehow managed to convince himself that something like an explosion would always occur to throw off mass and prevent the formation of a black hole. The field equations of his theory of relativity imply that a large star or cloud of gas would collapse in on itself and form a black hole. I would ask him why he didn't believe in black holes. If you could talk to Albert Einstein, what would you say? To ensure our long-term survival, we need to reach the stars. However, there is nowhere else in the solar system as suitable as the Earth, so it is not clear if we would survive if the Earth was made unfit for habitation. I think we have a good chance of surviving long enough to colonize the solar system. One might ask what is before that, but the answer is that there is nowhere before the Big Bang, just as there is nowhere south of the South Pole.ĭo you think our civilization will survive long enough to make the leap to deeper space? Although the universe doesn't have an end, it had a beginning in the Big Bang. It will expand forever, getting emptier and darker. Observations indicate that the universe is expanding at an ever increasing rate. An impersonal God.ĭoes the universe end? If so, what is beyond it? But I think that reason is the laws of physics rather than someone with whom one can have a personal relationship.

God is the name people give to the reason we are here. God doesn't exist, why did the concept of his existence become almost universal?
