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 ...
Gravitational waves are usually hunted by measuring distance—how space itself stretches and shrinks ever ...
Physicists have directly tracked tiny points of darkness in laser light racing faster than light itself, without breaking Einstein’s rules. The new measurements show that these “dark points” in a ...
A new theoretical study suggests that gravitational waves may leave subtle signatures not in giant detectors, but in the ...
Gravitational waves are ripples in spacetime produced by violent cosmic events, such as the merging of black holes. So far, ...
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 ...
