I will get excited when they can teleport something that actually has mass.

We still need a tricorder and overall better medical stuff. Cancer cures or better treatments, stasis etc and laser (or were they called phaser) guns!edit on 14/5/12 by shadowland8 because: (no reason given)
First Observation of Hawking Radiation
Hawking predicted it in 1974. Now physicists say they've seen it for the first time.
Today, Franco Belgiorno at the University of Milan and a few buddies say they've produced Hawking radiation by firing an intense laser pulse through a so-called nonlinear material, that is one in which the light itself changes the refractive index of the medium. As the pulse moves through the material, so too does the change in refractive index, creating a kind of bow wave in which the refractive index is much higher than the surrounding material. This increase in refractive index causes any light heading into it to slow down. "By choosing appropriate conditions, it is possible to bring the light waves to a standstill," say Belgiono and co. This creates a horizon beyond which light cannot penetrate, what physicists call a white hole event horizon, the inverse of a black hole. White holes aren't so different to black holes (in fact Hawking argues that they are formally equivalent). And it's not hard to imagine what happens to particle pairs that form at this type of horizon. If one of the pair crosses the horizon, it can make no headway and so becomes trapped. The other is free to go. So the horizon ought to look as if it is generating quantum particles.
