If the people of Comic-Con ruled the world...then tomorrow would be invented every day.

People say, oh we just need charismatic leaders to continue on to Mars. Now we've gone to the moon, of course Mars is next. No. Mars was never, of course, next. It is next if you think we went to the moon because we're explorers, but if you know we went to the moon because we were at war then we're never going to Mars. There's no military reason to do it, to justify the expenditure.

But one of the coolest things about meteorites is that most were formed four-and-a-half-billion years ago, during the birth of our solar system, when, for reasons not yet known, a cloud of gas and dust was transformed into a sun with circling planets.

Today, scientists sound the alarm on other environmental dangers. Vested interests still hire their own scientists to confuse the issue. But in the end, nature, will not be fooled.

It would be amazing if something completely spiritual sounding happened. Oh, my gosh! We'd be all over it. Because it's something new about the physical universe.

I'm not a scientist, I was not a good science student, I felt effectively alienated from science throughout my young life, and it was only when I became an adult that I began to really appreciate from a completely different angle the power of science.

Curious that we spend more time congratulating people who have succeeded than encouraging people who have not.
