Researchers investigate how light behaves in curved space
To investigate the influence of gravity on the propagation of light, researchers usually have to examine astronomical length scales and huge masses. However, physicists have shown that there is another way. In a recent study, they find the answers to astronomical questions in the laboratory, shifting the focus to a previously underappreciated material property -- surface curvature.
