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 ...

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

An artist's concept of multiple types of subatomic particles. Forget about turtles; for all practical purposes, it’s really particles all the way down. Consider the seemingly simple matter of their ...

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 ...

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 ...

When analyzing early universe data, the Standard Model of Cosmology suggests that the universe should be more “clumpy” that ...

The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions with matter.

Sensors buried deep in the Antarctic ice may help physicists figure out how gravity works in the quantum realm, the smallest scale of existence. A team of physicists says they’ve figured out how to ...
