I'd like - inviting aliens and have them observe what we do because so much of what we do that we take for granted will just be weird or extraordinary or just plain dumb when observed by an alien from another civilization.

While I'm a big fan of science fiction, especially as rendered in expensive Hollywood blockbusters, it's the real universe that calls to me. To fall into a black hole, that is more amazing than anything I've ever read in a science-fiction story.

To learn more about science, turn off your electronic device and go outside and look around a bit. Nature is calling you. Go on. The internet will still be here.

I knew my interest in the universe and I owned a telescope that I bought with money I earned by walking dogs. 50 cents per walk, per dog, and that accumulated quickly. I bought a camera, a telescope. I taught myself astrophotography. I did all this.

Astronauts are the only kind of celebrity I know who can have a line of people waiting for their autograph, even if the line of people does not know in advance the astronaut's name.

I always wanted to be respected for my mind.
