Particle accelerators smash tiny particles together to reveal the universe's building blocks. These machines have grown dramatically in size and power over time, leading to major discoveries. The ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

Neutrinos are ghostly, mysterious shape-shifters. New evidence bolsters the existence of an even ghostlier, “sterile” version of this strange particle. There are three types of neutrinos in the ...

In the microscopic world of the quantum particle, there are certain rules that are wholly unfamiliar to us on a macroscopic scale. If you measure a particle's position and ask "where are you," the ...

The Large Hadron Collider (LHC), the world's largest atom smasher, just discovered at least two previously unknown particles. The 17-mile (27 kilometers) underground ring near Geneva recently ...
