But in August 2023, a new discovery called the strong force into question. By smashing an isotope of oxygen with a beam of fluorine atoms, physicists have finally created oxygen-28 — a rare form ...

Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Researchers have measured the strong force, which binds together the particles that make up protons and neutrons, to the highest degree of precision ever. Despite being the most powerful of all ...

We dive into the weird world of quantum chromodynamics and the strong force. Quantum mechanics gets weirder as you go to smaller sizes and higher energies. It’s strange enough for atoms, but ...

The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, ... You probably know that the world all around you—your phone, your house, your cat—is made ...

Now, most of the atoms in the universe are the two simplest kinds: hydrogen, which has one proton, zero neutrons and one electron; and helium, which has two protons, two neutrons and two electrons ...

A force that couples electrons and neutrons could be an addition to the Standard Model, and a new study places an upper limit ...

Two puzzles of the model are why the weak force is so much stronger than gravity (what physicists call the hierarchy problem) and why the strong force—the force that binds atomic nuclei—doesn ...

Understanding how atoms form is a fundamental and important question, since they make up everything with mass. The question of where atoms comes from requires a lot of physics to be answered ...
