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.

The finding could be put to use at a new facility opening in 2020 that might create new elements—that is, nuclei with more than 118 protons—in addition to new isotopes of the known elements Scientists ...

In nuclear physics, "magic numbers" identify specific numbers of protons or neutrons that lead to especially stable nuclei. Recognizing these numbers helps scientists better understand the structure ...

The pressure inside the particles that make up every atom in the universe could be greater than the pressure inside the densest stars, according to a new measurement. Scientists at Jefferson Lab in ...

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 and neutrons that have briefly paired up in the nucleus have higher-average momentum, leaving less for non-paired nucleons. Researchers have now shown for the first time that this phenomenon ...

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 ...

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 ...
