But only in the last 70 years have we known for certain they were there. In 1956, physicists Clyde Cowan and Frederick Reines ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

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 ...

Our existence rests on a razor‑thin imbalance in the early cosmos. When the universe was young, matter and antimatter should ...

The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

The universe isn’t just growing—it’s speeding up as it does. That discovery stunned scientists, upending long-held ideas about gravity and motion in space. This rapid expansion wasn’t predicted by ...

Muons are unstable subatomic particles that spontaneously and rapidly transform into other particles via a process known as ...

Anomalous radio signals detected in Antarctica by the ANITA experiment were coming upward from Earth rather than down from the sky. Researchers used digital and mathematical simulations to test ...

Physicists are putting the finishing touches on the Jiangmen Underground Neutrino Observatory, or JUNO, which will delve into the secretive ways of neutrinos, a family of extremely lightweight ...

Kysa Johnson, “blow up 322 – the long goodbye (history of gold) – subatomic decay patterns and rapidly spinning neutron star PSR – B1509 – 58” (2017), ink on high gloss on board, 48 x 96 inches (all ...

Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a superposition of multiple states, as popularized by the Schrödinger's cat analogy, ...

Dipangkar Dutta receives funding from US Dept. of Energy and NSF. A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic particles. What ...
