Space time cloak could hide events in the folds 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,” says McCall. “So, theoretically, this person might be able to do something and you wouldn’t notice.”

This article is from November of last year, but it was never on IHC and for some reason never really made a splash across the internet, so here it is, because it’s fucking amazing:

New materials with the ability to manipulate the speed of light could enable the creation of a “space-time cloak” capable of masking events or even creating an illusion of “Star Trek”-style transportation, according to scientists in London.

The cloak, while currently only existing in mathematical theory, takes advantage of the potential properties of “metamaterials” — artificial materials designed and manipulated at a molecular level to interact with and control electromagnetic waves. Scientists have previously demonstrated that one possible use of metamaterials could be to render objects invisible by bending light around them. But Professor Martin McCall of Imperial College London says he has now extended the concept of invisibility to a cloak also capable of hiding events both in time and space.
