Strange particles that have mass when moving one direction but no mass when moving in another were first theorised more than a decade ago. Now, these mass-shifting particles have been glimpsed in ...

The collapse of the core forces electrons and protons together, creating a sea of particles called neutrons. This material is so dense that a mere sugar cube's worth of neutron star matter would ...

Quantum entanglement is a fascinating, counterintuitive phenomenon where two subatomic particles remain deeply connected, even if separated by billions of light-years. A change in one particle ...

In particular, the study looks at the high-energy jet of particles being blasted across space by the supermassive black hole at the center of the galaxy Centaurus A. Jets are visible to different ...

A team at the Japan Proton Accelerator Research Complex (J-PARC) in Tokai shot a laser at a stream of muons to bring the fast-moving particles to a near-standstill. Then, the researchers applied ...

Earth is subject to a constant bombardment of subatomic particles that can reach energies far higher than the largest machines A photomicrograph shows where high-energy electrons blazed through a film ...

Accelerators were invented in the 1930s to provide energetic particles to investigate the structure of the atomic nucleus. Since then, they have been used to investigate many aspects of particle ...
