When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

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 world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in Leiden has produced new insights that could be applied in 5G devices and the ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

Video of a black light experiment designed to show how fast a virus can spread in a restaurant setting is quickly going viral. The video, which was shot in Japan by the public broadcasting ...

Glow-in-the-dark coughs and sneezes? In the coronavirus era, this is what it takes for scientists to figure out which masks work best at stopping aerosol droplets from spreading after a cough or a ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

The experiment highlights one way the virus could rapidly spread on surfaces, though close contact with an infected person is the most common method of transmission A new video going viral in Japan ...

A black light experiment depicted in a viral video from Japan's NHK public broadcasting organization shows just how widely and quickly germs can spread, particularly during the COVID-19 era. The video ...
