Neil deGrasse Tyson on Aliens and the End of the Universe

Why is the universe the way it is? How did life begin? And how might it end? Astrophysicist Neil DeGrasse Tyson has spent his life in search of the answers. His new book, "Cosmic Queries," was co-authored with physicist James Trefil. Tyson joins our Walter Isaacson to discuss the book and what drives his thirst to explore the really big questions of the universe.
