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, ...
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 ...
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 ...
High-energy cosmic rays, 10 million times more powerful than particles accelerated in Earth's strongest atom smasher, may ...
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 ...
Does dark matter interact with itself? The answer may lie in vast clusters of colliding galaxies. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.
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 ...
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 ...
