What If You Could See 10 Seconds Into the Past?

You'd never lose your keys again. Magic tricks would be ruined. Nobody could lie to you. So why would you end up hiding behind sunglasses? You already see the past: sunlight is about eight minutes old when it reaches you, and your brain needs around a tenth of a second to build every picture, so it quietly guesses the present and throws the rest away. In this episode it stops throwing it away. The last 10 seconds glow on top of everything you look at, and you can rewind, pause and play the world like a video. We test it on the famous invisible gorilla experiment, on a 100 mph fastball and on a police lineup. Then we look at the price of living in two times at once, and at a real 1983 patient who had the exact opposite problem. And then, one summer, your family drags you to a very crowded beach. 0:00 The ghost with its hand in the jar 0:47 Your brain is already living in the past 1:47 Never lose anything again 2:30 You'd never miss the gorilla 3:31 Two cars, one of them real 4:57 Thousands of people, thousands of ghosts 7:34 Worth watching twice Would you want to see 10 seconds into the past, or is the present already enough work for your brain?
