How much do we really know about the quantum nature of space and time, the origins of the universe itself, and its most mysterious phenomena - black holes? In this program, Clifford Johnson, professor of physics at UC Santa Barbara, explains why understanding the laws of physics helps explain how the world around us works, and can fuel our imaginations to dream, invent, and create. Johnson works to engage the general public with scientific ideas, through many media outlets, including the entertainment industry. He has been a science advisor for many movies and TV shows.
