Researchers at the Technion-Israel Institute of Technology have published the first direct measurement of optical phase singularities — dark points within light waves — moving faster than the speed of light, confirming a theoretical prediction from the 1970s. The finding, published in Nature in March 2026, does not violate Einstein's relativity because these zero-amplitude geometric features carry no energy or information; the advance is primarily one of experimental technique, using ultrafast electron microscopy to track singularity dynamics in hexagonal boron nitride at femtosecond timescales.
