Sunlight takes eight minutes to reach your eyes. So why do physicists say no time passed for the light at all? In this lecture we follow a clock made of light, a pair of twins who stop being the same age, and particles that should be dead before they hit the ground, until one little minus sign explains everything.
0:00 The eight-minute trip that took zero time 1:14 The ball on the train that hides the whole secret 4:17 The clock made of light (and why it falls behind) 11:34 "So who's REALLY slow?" A twelve-year-old breaks physics 14:44 The photon myth almost everyone repeats 19:02 The twin who came home eight years younger 29:36 Pythagoras with a minus sign 42:54 Why there is no "now" across the universe 47:44 The light on your face, one last time
