Neil deGrasse Tyson: Sex in space requires ‘straps and things’


Neil deGrasse Tyson, the director of the Hayden Planetarium at the American Museum of Natural History, talks to Matt Lauer about the second season of his National Geographic channel late-night show “Star Talk,” explaining: “Everybody’s got a little bit of geek in them, and I’m there to find it.” He also says it’s likely we are not alone in the universe, and talks about the problems of zero-gravity sex in space.
