A plasma experiment succeeded in twisting light-like waves, and revealed a new, previously unknown rule of extreme physics.

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

New theoretical work suggests that the pattern of light emitted by atoms could be used to detect gravitational waves at ...

A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to stop thinking about. Yet the same wall that blocks the glow from your ...
