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

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 ...

A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic particles. What happens to these particles within atoms would stay unexplained ...

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

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 ...

The subatomic particles are incredibly numerous. About 1,000 neutrinos from stars other than the sun pass through a thumbnail ...

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

You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.

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 ...

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 ...

Physicist Richard Feynman invented them to describe the interactions between real particles. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. This ...
