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!
Stephen HawkingThink of our DNA. In the last million years, our DNA hasn't changed at all. It's really much the same as it was in the jungle, a million, two millions years ago. But in the last 200 years, our destructive capacities have increased many, many millions of times over. Why don't we see intelligent signals from outer space? Because in all likelihood, once the civilization reaches the point our civilization has reached, it destroys itself.
Stephen HawkingThe universe is governed by science. But science tells us that we can't solve the equations, directly in the abstract.
Stephen HawkingWhen I get to heaven I'm gonna find the guy in charge of the weather and kick his rear.
