The following is a transcript of the video. Stand on the equator and you'll be moving at 1,670 kilometers per hour — faster than the speed of sound! That's how quickly Earth rotates on its axis, from ...

Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system's arrow of time and ...
