Slow-proofed and worth the wait. Worth its weight in flour.
Summary
The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory has concluded its 25-year run with final collisions on February 6, 2026. The facility, which collided heavy ions at nearly light speed to recreate conditions of the early universe, produced groundbreaking discoveries about quark-gluon plasma and nuclear physics. The final run generated the largest-ever dataset, which will continue to yield scientific insights. RHIC's legacy includes technological advances in accelerators, detectors, and computing, with its infrastructure supporting future scientific endeavors.

· 5 pulledJust 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 Collider (RHIC) and crashed into one another at nearly the speed of light.
Milestone caps a quarter century of groundbreaking discoveries — with more to come from final run's largest-ever dataset — plus technological advances in accelerators, detectors, and computing.
RHIC's collisions of heavy ions at nearly light speed recreated conditions of the early universe, allowing scientists to study quark-gluon plasma — the state of matter that existed microseconds after the Big Bang.
The facility's 25-year run produced fundamental discoveries about the strong nuclear force, the structure of protons and neutrons, and the properties of quark-gluon plasma.
While the collider operations have ended, the scientific work continues as researchers analyze the massive dataset from the final run, which is expected to yield discoveries for years to come.
