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 ...

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 ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...

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 ...

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 ...

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 ...

Light can do more than illuminate a material. In some cases, it can temporarily change how electrons move through it. That ...

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 ...

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 ...

Contrary to what we all learned in elementary school science class, it turns out that heat may not be necessary to make water evaporate. Scientists at MIT have made the surprising discovery that light ...

Physicists have taken quantum strangeness to an extraordinary new level by measuring light across 37 dimensions. Their groundbreaking experiment pushes quantum mechanics beyond classical expectations, ...

The film explores the properties of light, including reflection and refraction, through various experiments. It demonstrates how light travels in straight lines, how mirrors can reflect images, and ...
