Physicists have demonstrated accelerating light beams on flat surfaces, where acceleration has caused the beams to follow curved trajectories. However, a new experiment has pushed the boundaries of what’s possible to demonstrate in a lab. For the first time in an expeirment, physicists have demonstrated an accelerating light beam in curved space. Instead of traveling along a geodesic trajectory (the shortest path on a curved surface) it bends away from this trajectory due to the acceleration theory of relativity.
Introducing a better way to study gravitational lensing.
