I want to know why the universe exists, why there is something greater than nothing.

So Einstein was wrong when he said, "God does not play dice." Consideration of black holes suggests, not only that God does play dice, but that he sometimes confuses us by throwing them where they can't be seen.

Many people do not like the idea that time has a beginning, probably because it smacks of divine intervention.

Just like a computer, we must remember things in the order in which entropy increases. This makes the second law of thermodynamics almost trivial. Disorder increases with time because we measure time in the direction in which disorder increases. You can't have a safer bet than that!

The boundary condition of the universe is that it has no boundary.

There is a real danger that computers will develop intelligence and take over. We urgently need to develop direct connections to the brain so that computers can add to human intelligence rather than be in opposition.

There is a fundamental difference between religion, which is based on authority, [and] science, which is based on observation and reason. Science will win because it works.
