A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

The photograph, titled “Underwater Hunting,” was a finalist for the 2025 Global Physics Photowalk. The competition, held ...

A neutrino with almost unimaginable energy slammed into Earth in early 2023, carrying roughly 220 petaelectronvolts, far beyond anything human machines can produce. The event, tagged KM3-230213A, has ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

A surprising and rare particle decay has left scientists puzzled as kaons, particles made up of quarks, are decaying in ways that defy current physics models. Could this anomaly indicate the existence ...

The model we have for understanding the universe’s fundamental particles is a bit like a gearbox: one tiny change to any one single particles’ properties throws off the mechanics of the other ...

Some of the most fundamental questions about our universe are also the most difficult to answer. Questions like what gives matter its mass, what is the invisible 96 percent of the universe made of, ...

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.

A committee-supported project or activity that has been completed and for which output dissemination has begun. Its committee has been disbanded and closeout procedures are underway. Elementary ...
