Scientists Photograph Light in Motion, Revealing Terrell Rotation at Near-Light Speeds
Researchers from the University of Vienna used pulsed lasers and ultrafast cameras to photograph light moving at near-light speeds, recreating the Terrell–Penrose rotation and showing how objects would appear rotated rather than squashed; by capturing slices of light and stitching them, they slowed light to about 2 m/s to visualize the motion, with implications for relativity studies, particle physics, and astrophysics.
