A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, creating a single particle of light that behaves as if it occupies 37 distinct ...

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 ...

Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu ...

New measurements from an experiment near the top of an extinct Mexican volcano have placed a stringent new limit on whether light can exceed the universe’s well-known top speed. Physicists have ...

The latest dark matter experiment kicks off this week, as physicists aim to identify the universe's most enigmatic particles. Reading time 2 minutes Long tubes, strong magnets, and bright lasers. Is ...

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 ...

Physicists want to ramp up their efforts to weigh neutrinos, which are perhaps the most mysterious of all elementary particles. Currently, only one experiment in the world has a shot at making such a ...
