Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The internal structure of a proton, with quarks, gluons, and quark spin ...

Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force -- one of the four fundamental forces in nature, along with gravity, electromagnetism, and the ...

From a research paper: “Probing Cold Dense Nuclear Matter”: The protons and neutrons in a nucleus can form strongly correlated nucleon pairs. Scattering experiments, where a proton is knocked-out of ...

A new study suggests that the positively charged particles may have an outsize influence on the properties of neutron stars and other neutron-rich objects. Neutron stars are the smallest, densest ...

Fast-moving protons are much more likely to pair up with fast-moving neutrons than with other protons in the nuclei of atoms, according to a recent experiment. The research confirms a previous ...

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

Big things come in small packages. That's the latest finding of the Department of Energy's Thomas Jefferson National Accelerator Facility, which has discovered that inside every proton in every atom ...

A few days ago I wrote about how different measurements of the Hubble parameter gave results that didn't quite agree. It's not the only example of such an experimental disagreement. In fact, one of ...

OAK RIDGE, Tenn. — Examining the smallest parts of the universe often takes the biggest kinds of equipment. At Oak Ridge National Laboratory, a unique piece of equipment the size of a building is ...

Adding a single proton to a doubly magic isotope of oxygen is enough to significantly alter its properties, an international team of physicists has discovered. Led by Tsz Leung Tang at the University ...
