Scientists stop light for 60 seconds

A team of researchers has succeeded in finding a way to stop light in its tracks for a full minute.

Experiments aimed at stopping light, which travels at the fastest known speed of 300 million meters per second, have been in the works for years. In 1999, physicists managed to slow it down to just 17 meters per second and two years later succeeded in halting it completely for a fraction of a second. To stop it for a full minute however is a feat that has, until now, remained impossible.

To achieve it, George Heinze and his team at the University of Darmstadt in Germany fired a laser at an opaque crystal and used a combination of magnetism and optics to slow the light down. Their success could pave the way towards secure quantum communications over long distances.

"To break the minute barrier, George Heinze and colleagues at the University of Darmstadt, Germany, fired a control laser at an opaque crystal, sending its atoms into a quantum superposition of two states."

Soon, I can turn the light off and beat it to bed.

The old quantum superposition trick eh. Why didn't I think of that?

Or aiming a flashlight at walls.

Too many videos already; we have learned to disregard them as they are too easy to fake.

A proper light saber would be of little use beyond that of a flashlight. A gun is more effective if you want to take them out.

Are you serious? You can weld, cut, etc. metal, deflect laser beams of death, heat things up, light a cigarette. Just think, when you get into a divorce and the wife wants half of everything...

There is nothing there. I can do all those things in a machine shop now at a lot less cost. I don't think that is what the technology is about anyway. Uses for stopped light have to do with storage of information or encoding things maybe but ot creaiting a focused beam.

It depends on how they slowed the light. What is actually happening. an opaque crystal? It really just sounds like the energy is being absorbed then re emitted. Many internal process could be the culprit. It could be said that one 'slowed' light if there was a complex set of perfect zig zaggy mirrors that increased the distance light had to travel to make it somewhere. If I set the mirrors (probably using fractal geometry) to equal roughly 186,000 miles in 30 feet. Light would 'travel' 30 feet per second relative to me. Im skeptical until I understand what's really happenin... [More]
