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 ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

A new study identifies a transition in the strong nuclear force that illuminates the structure of a neutron star's core. Most ordinary matter is held together by an invisible subatomic glue known as ...

Physicists are drawing closer to answering a long-standing mystery of the Universe: how long a neutron lives. Neutrons are electrically neutral particles that usually combine with protons to make up ...

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 ...

An ancient crocodile’s last meal might never have come to light were it not for researchers deciding to scan the rock-embedded fossil with a beam of neutrons. The scientists had set out to see if ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Physicists have long-suspected that the building blocks of protons experienced quantum entanglement. Now, researchers have the first direct evidence — after using a trick to infer subatomic particles' ...

Protons can hold an elementary particle heavier than themselves. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Protons may have more "charm" ...

"Electrons will collide with protons or larger atomic nuclei at the Electron-Ion Collider to produce dynamic 3-D snapshots of the building blocks of all visible matter," according to the U.S.
