The Large Hadron Collider (LHC) has begun its first-ever collisions of oxygen ions, in the latest attempt to understand the early universe. The LHC is largely famous for its proton-proton collisions, ...

An innovative algorithm for detecting collisions of high-speed particles within nuclear fusion reactors has been developed, inspired by technologies used to determine whether bullets hit targets in ...

A pair of astrophysicists with Princeton University and the SLAC National Accelerator Laboratory found possible evidence of dark matter particles colliding. In their study, published in Physical ...

Particles known as tensor mesons are created when high-energy photons interact. These mesons have now been proposed to have a larger effect on photon behavior than previously thought, and provide a ...

But thunderclouds present a more perplexing puzzle. Here, both colliding particles are fundamentally the same material: frozen water. A delicate ice crystal hitting rough graupel should be like ...

A suborbital experiment indicates that centimetre-sized clusters of tribocharged submillimetre grains resist erosion by individual grains with collision speeds up to around 0.5 m s –1. The stability ...

The original version of this story appeared in Quanta Magazine. In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She ...

A new analysis of data from the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) reveals fresh evidence that collisions of even very small nuclei with large ones might create tiny ...
