How did the universe begin? It's a question that plagued scientists for centuries, and one that astrophysicist Neil deGrasse Tyson explores in his recent book Origins: Fourteen Billion Years of Cosmic Evolution. He joins us on Focus today to discuss the formation of the universe, as well as its galaxies, planets... and inhabitants.
