I first met Neil deGrasse Tyson at a bug eating event at the Museum of Natural History when he was munching on a fried tarantula. You may remember him as the host of Cosmos: A Spacetime Odyssey. That was the continuation of a television series that had originally starred Carl Sagan, another well-known astrophysicist. Tyson often appears on the media talking about his favorite subject: the universe. He’s also the Director of the Hayden Planetarium in New York and has written more than 17 books. The latest is called A Brief Welcome to the Universe. But when you’re talking to Neil deGrasse Tyson, as you’ll discover, nothing is brief.
