“Darkness faster than light”: Researchers were able to confirm a prediction from the 1970s that the speed of “dark points” within light waves exceeds the speed of light. They do not carry energy or information, meaning they do not violate Einstein’s principle.

Researchers from the Technion–Israel Institute of Technology have achieved the first direct measurement of “dark points” within light waves, experimentally confirming a theoretical prediction from the 1970s that these features can move faster than the speed of light. The study, published in Nature, was led by Prof. Ido Kaminer and an international team of collaborators. The “dark points,” also known as optical vortices, are locations within a l…
