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 ...

Physicists have taken a step that sounds like science fiction: they have coaxed light into behaving as a “supersolid,” a ...

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 ...

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 ...

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 ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

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 most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...
