If We Had a Really Big Telescope, Could We See Star Wars?
Everyone likes watching Star Wars. They're awesome movies, and I think we've all had that majorly trippy moment when we realize "A long time ago" means that everything we're watching happened in the past. But if it was so long ago, and so far away, that the light is reaching us now-- does that mean we could theoretically watch Star Wars live?Read on...
Researchers Trap Light for One Full Minute, New Super Villain Weaponry Likely on Its Way
A team of scientists at Germany's University of Darmstadt have broken a major -- and bizarre -- record, bringing light itself to a full stop inside a crystalline structure and keeping it stopped for a full minute. The groundbreaking research could have major implications for storing information in quantum memory.Read on...
New Fiber Network Clocks in at 99.7% Speed of Light, 73.7 Terabits Per Second
Fiber optic cable is responsible for some of the fastest data transfer speeds on Earth, and a new type of fiber just got even faster. University of Southampton researchers have created fibers that can transmit data at 99.7% the speed of light. That means data can be transmitted up to incredible speeds like 73.7 terabits per second, but what it doesn't mean is a faster Internet connection for us common folk.Read on...
MIT Develops Metamaterial That Slows Down The Speed of Light
There's always a lot of fuss about getting other things to go as fast or faster than the speed of light. But what about changing the speed of light? Is there anything useful we could do by slowing light down rather than speeding things up? As it turns out, there are all kinds of benefits to be had from slowing light down and making it easier to capture, which is why MIT has been working on nanotech "metamaterials" that can do just that: Slow down the speed of light.Read on...
