Coming for Christmas: 3D TV?
The mathematicians who first created the invisibility cloak now think that the same technology could be used to create 3D TV.
The secret is a mathematical construct known as “wormholes.” Mathematician Allan Greenleaf says, “You could pass an object into one end [of their wormhole tube], watch it disappear as it traveled the length of the tunnel, and then see it reappear out the other end.” The wormholes themselves would be invisible, but their ends could transmit light carried up from below. It would be as if thousands of pixels were simply floating in the air.
But Greenleaf admits that, even though the mathematics show that it’s possible, a TV set that broadcasts in 3D is a very long way off (so it won’t be available THIS Christmas!)
