For the first time, physicists have discovered that ‘holes’ of light can travel faster than light itself. They are known as phase singularities or optical vortices, and since the 1970s, scientists have predicted that, just as the eddies in the river can move faster than the water flowing around them, so can the waves of … Read more

Dark spots in light waves may appear to disrupt the speed of light, according to new research from scientists at the Technion-Israel Institute of Technology, confirming the predictions of a half-century-old theory. What the team calls “dark points” are actually vortices – tiny holes in the wave structure of light – as revealed in a … Read more
