Aside from communications satellites, space is devoid of industry.

In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection.

A truly open mind means forcing our imaginations to conform to the evidence of reality, and not vice versa.

When a person's religious beliefs cause him to deny the evidence of science, or for whom public policy morphs into a battle with the devil, shouldn't that be a subject for discussion and debate?

What people believe impacts on what they do. And it's not as if religion is universally bad. Of course it's responsible for many peoples doing good actions.

We should provide the meaning of the universe in the meaning of our own lives. So I think science doesn't necessarily have to get in the way of kind of spiritual fulfillment.

Forget Jesus. The stars died so that you could be here today.
