Dark spots break speed-of-light limit. Kind of. Researchers from Technion in Israel have filmed the motion of tiny dark spots that move faster than light. These dark spots are places where the light wave’s intensity drops to zero due to interference. They had the light propagate on a material (boron nitride) where it couples to the vibrations of the material. Then they measured the speed with ultrafast electron microscopy to confirm that it broke the speed of light limit. Concretely, they measured that the dark spots moved at 1.04 times the speed of light in vacuum. This is possible because the dark spots themselves are patterns, and not physical objects. They can move faster than light just like the image of a laser pointer, swept across a distant surface, can move faster than light: Because the image is not a physical object, it is just a pattern formed from physical objects which themselves obey the speed of light limit. So this is a very neat demonstration, but it does not violate any known physical principle and no, it does not allow us to send information faster than light.
