It’s been a rough couple billion years. I don’t know why, I just haven’t been feeling the same way as I did in the billions of years after the Big Bang. Back then, being a quark meant something – it had weight you know? Muons and leptons took you seriously, electrons wanted to get together […]

A little while ago, I was talking casually to an old arms-controller. “What have you been up to?” I said. “Talking to the Russians,” he said. The Russians he would have been talking to were probably nuclear policy experts or nuclear weapons scientists and they probably would have been talking about ways of controlling international […]
David Grinspoon is a comparative planetologist and an astrobiologist. He’s also a big book nerd, and his love for both fiction and nonfiction are proudly on display in his own book, Earth In Human Hands: Shaping Our Planet’s Future. The book was recently featured in an ongoing series on “Resistance Reading” selected by authors and published […]

Bennu is important for at least four reasons: Local space history may recorded in its rocks, which are about as old as the formation of the solar system. It is carbon-rich and scientists think […]
I usually avoid talking to people at the gym. But a few weeks ago, the man next to me had his shoes untied, and I couldn’t help myself. The laces were bright red, and extremely long. He was doing side steps that looked like they had high trip potential. And I was extra-sensitive to falls […]
UPDATE, 10/27/2020: This post is about, among other things, Peter Ganz, a German philologist with an unlikely personal history. One of his sons, David, just wrote telling me about a centenary at Oxford University that celebrates Peter’s accomplishments. I thought you might like to know. I mean, the man left Buchenwald, then helped spy on […]
Years ago, talking about the persistent rumor that the Hubble Space Telescope was an off-the-shelf spy satellite retrofitted for astronomy*, I told a NASA employee that I was pretty sure academic astronomers were culturally anti-military and they wouldn’t be crossing lines and dealing with spies or the defense department. The NASA employee looked at me […]
