'Spacetime cloak' could conceal history

.The "spacetime cloak" would speed up and slow down light to give the illusion that events have not happened.

A "cloaked" individual could, for instance, travel from one place to another while appearing to vanish and rematerialise instantaneously in a new location. Such a device would also make a mockery of CCTV, disproving the adage that the camera never lies.

A scientifically-savvy thief with access to the technology could open a safe, empty its contents, and make his escape right under the watchful eye of a surveillance camera.

The video footage would show that the safe door was closed all the time. In effect, events in history could be "edited out" so that they never appear to have happened.

It sounds like the stuff of fantasy, but scientists at Imperial College London have proved it could work in theory by adapting standard fibreoptic technology.

As well as being a safe-cracker's dream, they believe the idea has a wealth of more practical applications in the realms of data processing and computing.

Lead scientist Professor Martin McCall said: "We have shown that by manipulating the way the light illuminating an event reaches the viewer, it is possible to hide the passage of time.

"If you had someone moving along the corridor, it would appear to a distant observer as if they had relocated instantaneously, creating the illusion of a Star Trek transporter. So, theoretically, this person might be able to do something and you wouldn't notice."

In previous experiments scientists have shown that light can be curled around objects to make them seem invisible.

The "invisibility cloak" technology employs so-called "metamaterials" whose structure allows light rays to be bent or even reversed.

The new research goes a step further by devising a way to conceal events

  • Wow is all I can say....gotta do some more research into this science....it is incredible and would change everything, not sure it is a good thing though. There will always be those who use technology not for the betterment of mankind. It seems I have some reading to do.....starting now, bye bye.
  • Tele-transportation is something that was once done but the knowledge has been lost. It could be because of the thief. I hope that when we again have such technilogy that we have risen above thiefery and discuised events. Now, if I can take myself to the grocery store and return with my packages and not add a drop of pollution to the air then that is good. Such a divise was in use during the time of the Garden of Eden accorting ot the Urantia book. Also it is spoken of in a book about Thiabouha which is about the people from Easter Island long long ago. It is a scary sinerio for a mass deception from something that looks so real and causes real reactions. I hope that by the time we utilize such technology on a regular basis we have progressed for the better of all people.
