Work gives you meaning and purpose and life is empty without it.

It is said that there's no such thing as a free lunch. But the universe is the ultimate free lunch.

All that my work has shown is that you don't have to say that the way the universe began was the personal whim of God.

Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill.

What was God doing before the divine creation? Was he preparing hell for people who asked such questions?

No one can resist the idea of a crippled genius.

The large-scale homogeneity of the universe makes it very difficult to believe that the structure of the universe is determined by anything so peripheral as some complicated molecular structure on a minor planet orbiting a very average star in the outer suburbs of a fairly typical galaxy.
