00:00If you start turning this machine right now, you could keep turning it for the rest of your life.
00:04And it still wouldn't finish moving, not in your lifetime, not in a thousand lifetimes.
00:08It has a hundred gears. Each gear turns ten times slower than the one before it.
00:12The first gear spins in 3.5 seconds. The fifth gear takes ten hours.
00:16The seventh, a month. By the eleventh, you have to wait a thousand years for just one turn.
00:21After 4.6 billion years, the entire age of Earth, the 18th gear would have moved only halfway.
00:26Could you force the last gear to turn? Only if you could spin the first one faster than light.
00:31Meaning, even with all the energy of the Big Bang, this machine would still refuse to move.
