The observable universe is jammed with billions of galaxies, which in turn are packed with trillions of stars and who knows how many planets. So wouldn’t you think the chances of intelligent life, other than ourselves, exists in one of these faraway places? Or are we looking in the wrong place?

Reich explains in this edition of minutephysics.
