‘Time Cloak’ Makes Events Invisible

You have to imagine that if the Pentagon is behind this, they are way ahead of what is described here, by Seth Borenstein for AP via Physorg:

It’s one thing to make an object invisible, like Harry Potter’s mythical cloak. But scientists have made an entire event impossible to see. They have invented a time masker.

Temporal cloak

Think of it as an art heist that takes place before your eyes and surveillance cameras. You don’t see the thief strolling into the museum, taking the painting down or walking away, but he did. It’s not just that the thief is invisible – his whole activity is.

What scientists at Cornell University did was on a much smaller scale, both in terms of events and time. It happened so quickly that it’s not even a blink of an eye. Their time cloak lasts an incredibly tiny fraction of a fraction of a second.

Space-Time Cloak Possible, Could It Make Events Disappear Too?

4467116919_603041818fCould an entire bank heist take place at an open bank with no one seeing it? The National Geographic reports:

It’s no illusion: Science has found a way to make not just objects but entire events disappear, experts say.

According to new research by British physicists, it’s theoretically possible to create a material that can hide an entire bank heist from human eyes and surveillance cameras.

“The concepts are basically quite simple,” said Paul Kinsler, a physicist at Imperial College London, who created the idea with colleagues Martin McCall and Alberto Favaro.

Unlike invisibility cloaks — some of which have been made to work at very small scales — the event cloak would do more than bend light around an object. Instead this cloak would use special materials filled with metallic arrays designed to adjust the speed of light passing through.
