To believe in a universe as young as 6 or 7,000 years old is to extinguish the light from most of the galaxy.

I like seeing how people have succeeded when others would have presumed they would have failed, and others just go along with whatever everyone else does.

If humans one day become extinct from a catastrophic collision, there would be no greater tragedy in the history of life in the universe. Not because we lacked the brain power to protect ourselves but because we lacked the foresight. The dominant species that replaces us in post-apocalyptic Earth just might wonder, as they gaze upon our mounted skeletons in their natural history museums, why large headed Homo sapiens fared no better than the proverbially peabrained dinosaurs.

I can't tell you how many people say they were turned off from science because of a science teacher that completely sucked out all the inspiration and enthusiasm they had for the course.

One of the most significant events in our distant past is still perhaps the greatest mystery: the origins of life itself.

It's progress I think, that science has joined philosophy, metaphysics & religion as subjects drunk people argue about in bars.

'Boldly going where hundreds have gone before' does not make headlines.
