A team of physicists at Cornell University has created a wrinkle in time. Actually, it’s more like a teeny tiny moth hole in time. Inside it things can occur that are entirely undetectable, at least to ordinary observers. It’s as if they never happened.
This phenomenon, known as “temporal cloaking,” is the latest addition to a world that once existed only in children’s literature and science fiction — a place where objects are invisible and events are unrecorded.
A good analogy is to Imagine you are watching a train of 40 cars coming toward you head-on. You notice a man on a motorcycle stopped at a crossing. If somehow the train uncoupled between the 20th and 21st cars and the front half of the train sped up a little and the back half slowed down, a gap would open. If the gap opened at the crossing and the motorcyclist was fast enough, he could pass through the train to the other side of the track. If the cars then recoupled and the train regained its constant speed, it would appear to you that nothing had occurred — except, of course, the position of the motorcyclist changed.
This is literally so so so cool and clever and just amazing.
