Brian Greene tackles the question whether we are alone in the universe. Space is so vast it’s filled with trillions and trillions of stars. While we may get star struck when we look at the night sky and gaze in it’s seemingly endless sea of stars hosting countless Earth like planets, and think we could not possibly be alone in the galaxy, Physicist Enrico Fermi reminds us that we need evidence to infer the existence of aliens. Hence, his famous paradox.
