For the past quarter-century, scientists using a particle collider on Long Island have been smashing the nuclei of gold atoms together at nearly the speed of light to create the hottest matter ever ...

When the universe first burst into being, all of space was a cosmic cauldron filled with a roiling, fiery liquid of fundamental particles heated to trillions of degrees. But this seething primordial ...

Before the RHIC shut down, it was the only operational particle collider in the U.S. and one of two heavy-ion colliders in the world, the other being the Large Hadron Collider at CERN in Switzerland.

Just after 9 a.m. on Friday, Feb. 6, 2026, final beams of oxygen ions—oxygen atoms stripped of their electrons—circulated through the twin 2.4-mile-circumference rings of the Relativistic Heavy Ion ...

A single subatomic particle that hit Earth in 2023 carried roughly 100,000 times more energy than anything humanity has ever produced in a particle collider. It was a neutrino, one of nature’s most ...
