A team of scientists has replicated one of Thomas Edison's early experiments from his quest to make the lightbulb, but with ...

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 ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and Fundamental Forces from Imperial College London. Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Explains the concept of light traveling in straight lines and demonstrates this through various experiments. It shows how light can be observed through holes in cards, how it behaves in a lightproof ...

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 ...

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 ...

The ALPS (Any Light Particle Search) experiment, which stretches a total length of 250 metres, is looking for a particularly light type of new elementary particle. Using twenty-four recycled ...
