IntroductionWhether he's teaching class, socializing at a cocktail party or talking to visitors at the planetarium where he works, Charles Liu knows that sooner or later he's going to get asked at least one of three questions:
• Is there a God?
• Are there aliens?
• What would happen if I fell into a black hole?
"I've never been in a public environment where people know what I do where at least one of these questions was not asked," Liu said. He is an astrophysics professor at the City University of New York Staten Island and an associate at the Hayden Planetarium at the American Museum of Natural History.
Over the years, Liu has developed some pretty solid answers, based on scientific evidence and his own opinion, to those three burning questions. Here's what he told us.
