I learned in October 2022’s Breakthrough that the spikes of stars in high-power photos are called diffraction spikes. Why do they appear as two crosses at 45 degrees to each other? The diffraction ...

Dark Spots Inside A Laser Beam Filmed Moving Faster Than Light In A Nutshell Scientists have filmed dark spots inside a light ...

Researchers at the Technion-Israel Institute of Technology have measured “dark points” inside light waves that appear to ...

Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...

Dark structures inside light waves can briefly move faster than light without breaking relativity or transmitting energy or information.

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 ...

A new theoretical study suggests that gravitational waves may leave subtle signatures not in giant detectors, but in the light emitted by atoms.
