One of the things that fascinates me most is when people are so charmed by the universe that it becomes part of their artistic output.

Perhaps these ancient observatories like Stonehenge perennially impress modern people because modern people have no idea how the Sun, Moon, or stars move. We are too busy watching evening television to care what's going on in the sky.

Eventually, the Sun will swell to occupy the entire sky as its expansion subsumes the orbit of earth. Earth's surface temperature will rise until it matches the 3,000-degree rarified outer layers of the expanded Sun.... But not to worry. We will surely go extinct for some other reason long before this scenario unfolds.

The people talking on their cell phone and following GPS instructions to where grandma's house is saying I don't need space - excuse me, that's how you know where grandma lives, and when to make the left turn.

For your own safety, do not ever tell an astrophysicist, I hope all your stars are twinkling.

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