Scientists slow down light particles
Glasgow, Scotland (UPI) Jan 23, 2015
The speed of light is a limit, not a constant - that's what researchers in Glasgow, Scotland, say. A group of them just proved that light can be slowed down, permanently. Scientists already knew light could be slowed temporarily. Photons change speeds as they pass through glass or water, but when they exit the other side and return to a vacuum (like outer space) they speed back up. In a new experiment at the University of Glasgow, however, scientists were able to permanently manipulate ... read more
