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 ...

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

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 ...

They're tiny, invisible, and travel across the universe. And trillions of them just flew through your body. What are they? Neutrinos ‒ and scientists Wednesday announced the discovery of the most ...

China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...

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

As the name suggests, particle accelerators involve accelerating subatomic particles to incredibly high speeds and smashing them into tiny targets. When you purchase through links on our site, we may ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

The Nobel-Prize-winning physicist Peter Higgs has died at age 94. He was celebrated for his work on the mass of subatomic particles. Today the University of Edinburgh announced the death of the Nobel ...
