One of the reasons we're here, that we exist at all, is that Earth, cosmically speaking, is in a relatively peaceful place: orbiting our Sun in a near perfect circle.

If cosmological theory were dominated by women, who are no strangers to cycles, how can we know for sure that we wouldn't then be told that the oscillating universe is the more aesthetically fulfilling alternative?

I'm a fan of the planets in any combination. When I was born, Mercury, Venus, Jupiter, Saturn, Uranus, Neptune, Pluto, the Sun, and the Moon were all in the sky.

The dinosaurs never saw that asteroid coming. What's our excuse?

NASA was invented as a response to Cold War steps. There are those who presumed that we went to the moon because we're explorers. We went to the moon because we were at war with the Soviet Union. And so when it became clear that they (Soviet Union) were not going to the moon, we're done with the moon.

I wonder if, in fact, we have been observed by aliens and upon close examination of human conduct and human behavior they have concluded that there is no sign of intelligent life on Earth.

I've accomplished enough in life so that I do not fear death.
