What if Speed of Light comes to Crawl !!

Well, we all know, light is the fastest thing in the universe. The complete physics depends upon the speed of light. But what if, the light comes to crawl ??
This is the biggest question that arises in every ones mind. Scientist have been working over it for decades. and there years of hard work is paying them now. And the scientists at the University of Glasgow have achieved a breakthrough in this area. They've managed to slow the speed of light to a relative crawl – 741 miles per hour, or about the speed of sound. While that’s still fast relative to our own experience, remember that in a vacuum, the speed of light is 186,252 miles per second. So this is an incredible achievement.

Here’s how it works:

In research detailed in the latest edition of the journal Science, researchers Dr Sonja Franke-Arnold, Dr Graham Gibson and Prof Padgett, in collaboration with their colleague Professor Robert Boyd at the Universities of Ottowa and Rochester, took a different approach and set up an experiment: shining a primitive image made up of the elliptical profile of a green laser through a ruby rod spinning on its axis at up to 3,000 rpm.

Once the light enters the ruby, its speed is slowed down to around the speed of sound (approximately  741mph) and the spinning motion of the rod drags the light with it, resulting in the image being rotated by almost five degrees: large enough to see with the naked eye.

The rotation of the image is significant because, according to Dr. Franke-Arnold it can be used to encode information, giving the technique a possible application in computing. “Images are information and the ability to store their intensity and phase is an important step to the optical storage and processing of quantum information, potentially achieving what no classical computer can ever match.”
