How to break the speed of light
You can break the speed of light in your back yard! (but don't worry, Einstein is still right) Tweet it - http://bit.ly/rOv00A Facebook it - http://on.fb.me/tOzkUm minutephysics is...

You may have heard that Einstein's theory of special relativity imposes a cosmic speedlimit: nothing can travel faster than the speed of light. Well, that's wrong. All thatEinstein said was that light moves at the same speed in every reference frame - andwhile this implies that nothing with real mass can move faster than light, it doesn'timpose a cosmic speed limit.Because you can break the speed of light in your backyard. All you have to do is pointa laser beam at the moon and flick your wrist. The spot of light from the laser beam willtravel across the moon's face in about half a millisecond, which means it's travelingat twenty times the speed of light!How is this possible? Well, think about a computer screen – what's the speed...
