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 ...

Albert Einstein and Niels Bohr had an ongoing rivalry about the true nature of quantum mechanics, and came up with a thought ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
