The universe is incredibly old, astoundingly vast and populated by trillions of planets — so where are all the aliens? Astronomer Stephen Webb has an explanation: we’re alone in the universe. In a mind-expanding talk, he spells out the remarkable barriers a planet would need to clear in order to host an extraterrestrial civilization — and makes a case for the beauty of our potential cosmic loneliness. ”The silence of the universe is shouting, ’We’re the creatures who got lucky,'” Webb says.

In this talk, she invites us to imagine a world where the Ada Lovelaces of tomorrow grow up to be optimistic and brave about technology and use it to create a new world that is wonderful, whimsical and a tiny bit weird.
