When I was first diagnosed with ALS, I was given two years to live. Now 45 years later, I am doing pretty well.
Stephen HawkingThere 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.
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.
