A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Discovery of superluminal correlations within 2D hexagonal boron nitride could advance super-resolution electron microscopy ...

For the first time, physicists have observed that 'holes' in light can move faster than the light itself. They're known as ...

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 ...

Physicists in Leiden have recreated Thomas Young’s iconic double-slit experiment using gigahertz sound waves on gallium arsenide, revealing both parallels and differences with light. The study found ...

A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted ...

A recent discovery by materials science researchers in Drexel University’s College of Engineering might one day prevent electronic devices and components from going haywire when they’re too close to ...
