While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.

The chances that your tombstone will read 'Killed by Asteroid' are about the same as they'd be for 'Killed in Airplane Crash.'

In the movie, the stars above the ship bear no correspondence to any constellations in a real sky. Worse yet, while the heroine bobs... we are treated to her view of this Hollywood sky-one where the stars on the right half of the scene trace the mirror image of the stars in the left half. How lazy can you get?

We are not figuratively, but literally stardust.

I think that intelligence is such a narrow branch of the tree of life - this branch of primates we call humans. No other animal, by our definition, can be considered intelligent. So intelligence can't be all that important for survival, because there are so many animals that don't have what we call intelligence, and they're surviving just fine.

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