That's Cool: Frozen Light!‽

"Any sufficiently advanced technology is indistinguishable from magic."Arthur C. Clark
According to this article from the New York Times, Harvard scientists have figured out how to freeze light in its tracks. And, just to make things more interesting, they have been able to make the light pulse reappear somewhere other than where it was first frozen.

The very thing Einstein himself believed could never happen.

That ability to catch, store, move and release light could be used in future computers to process information encoded in the light pulses.

Upon further research I find that this is actually old news, having been accomplished in 2001.

But what I find even cooler is another Harvard Physics Professor might be on the verge of proving that our visible world of four dimensions could be embedded in a higher-dimensional universe.

Harvard Prof Lisa Randall presents her theory on the geometry of space, extra dimensions, and gravity in her book, Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions.

Here's the link to the article, your can check her out yourself.
