Scientists at the Imperial College of London think that, using metamaterials and some fancy math, a real-life space-time cloak may be possible. The space-time cloak would not only make objects invisible, but also be able to hide events in time. It should be possible, the scientists believe, to conduct experiments to prove the idea with current technology.

The space-time cloak won't provide teletransportation. Travelers will have to exert physical effort to travel, but it creates the illusion of instant transportation by changing the speed at which light travels through a medium.
