Light typically travels in a straight line, but physicists have found several ways to make light beams curve. A new experiment adds an extra twist by combining two separate light-bending phenomena: one involving the curved space known from general relativity, the other based on shape-preserving accelerating wave packets developed in optics. Mordechai Segev and his colleagues from the Technion – Israel Institute of Technology are the first to experimentally observe an accelerating beam in curved space.
