Back in 2000, a team of physicists led by Lijun Wang at the NEC Research Institute in Princeton, USA, pulled off a mind-bending experiment. They fired a precisely shaped laser pulse through a special ...

Scientists captured the first images of the Terrell-Penrose effect, showing objects near light speed appear rotated rather than compressed in photos.

If there is an absolute law in the universe, it’s that nothing can travel faster than the speed of light. For science-fiction enthusiasts, that’s a bit depressing. Space is big, and while the speed of ...

The method involves stitching together many thin “slices” of light reflecting off an object.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...
