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 ...

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 ...

PROVIDENCE, R.I. [Brown University] — Amid the many mysteries of quantum physics, subatomic particles don’t always follow the rules of the physical world. They can exist in two places at once, pass ...

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 ...

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 ...

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

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 ...

In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

The universe is a strange place on very small scales. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. What makes up the matter we perceive in the ...

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 ...

Neutrinos are some of the most elusive particles that are well-known to science. These tiny subatomic particles have no electric charge and an extremely small mass, making them incredibly difficult to ...
