Cosmic Queries

Neil deGrasse Tyson is a serious astrophysicist, but you wouldn’t necessarily know that from his witty quips and plain language explanation of the universe on his Twitter feed. Neil deGrasse Tyon's podcast called StarTalk has become so popular that he now published a book tackling the most confounding questions listeners have asked, like “How did it all begin?” and “What is the Universe Made Of?” Neil deGrasse Tyson, whose new book "Cosmic Queries" is from National Geographic, thrives on this stuff.
