What If You Never Left the World's Quietest Room?

The world's quietest room is so silent you can hear your own heartbeat. Everyone's heard of the 45-minute "limit". But what if you never came out? We follow 70 years of real experiments, from 15 minutes in the dark to 520 days sealed inside a fake spaceship, to find out what silence and isolation actually do to your mind. The answer isn't what the myth says. 0:00 The world's quietest room 0:38 Minus 24.9 decibels 1:15 15 minutes in the dark 1:54 Try it: just listen 2:25 The 45-minute myth 2:47 Days: the McGill experiments 4:04 Weeks: lost in a cave with no clock 4:49 Months: 205 days, a mouse, and Mars-500 5:48 The twist 6:54 So, could you beat the room?
