Everyone experiences time differently. This is true at the level of both physics and biology. Within physics, we used to have Sir Isaac Newton’s view of time, which was universal and shared by everyone. But then Einstein came along and explained that how much time elapses for a person depends on how they travel through space (especially near the speed of light) as well as the gravitational field (especially if its near a black hole). From a biological or psychological perspective, the time measured by atomic clocks isn’t as important as the time measured by our internal rhythms and the accumulation of memories. That happens differently depending on who we are and what we are experiencing; there’s a real sense in which time moves more quickly when we’re older.

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.

“We think of time in the way that other people think of space. What other people are doing in space, we can do it in time,” said Moti Fridman, a researcher at the School of Applied and Engineering Physics at Cornell University .
