Physicists Discover Optical Vortices Moving Faster Than Light
Physicists have observed optical vortices, or phase singularities, moving faster than light itself. These vortices, akin to whirlpools in a wave of light, do not violate relativity as they carry no mass, energy, or information. The discovery was made using high-speed electron microscopy, which captured the dynamics of these vortices in real time. The experiment involved a two-dimensional material, hexagonal boron nitride, which supports phonon polaritons—hybrids of light and atomic vibrations. This breakthrough provides a technological tool to map nanoscale phenomena in materials, enhancing image sharpness through electron interferometry.
