"Cosmos" host and astrophysicist Neil deGrasse Tyson recently shot down the ideas of anyone who still thinks the Earth is flat. In a new YouTube video on the scientist's StarTalk channel, he used examples ranging from space observations to ancient Greek experiments in a conversation with stand-up comedian Chuck Nice. "So, tell me, Neil, is the Earth flat?" Nice said to open the conversation. "We have video from space of the rotating, spherical Earth. The Earth is round," was Tyson's laconic response.
