While the Higgs mechanism was confirmed by the Large Hadron Collider—leading to the 2013 Nobel Prize—it fails to account for ...

Researchers using the JUQUEEN supercomputer have computed the small mass difference between protons and neutrons. The fact that the neutron is slightly more massive than the proton is the reason why ...

Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, ...

In this video, we explore the existence of neutrons and their transformation into protons. We discuss why free neutrons are ...

The fact that the neutron is slightly more massive than the proton is the reason why atomic nuclei have exactly those properties that make our world and ultimately our existence possible. Eighty years ...

Dr Karl: What is the Universe made from? Well, 95% of it is made up of the mysterious Dark Energy and Dark Matter. But focusing on the stuff we can see, practically all of that is made from atoms. But ...

When it comes to weighty matters, quarks and gluons rule the universe, a new study confirms. One of the largest computational efforts to calculate the masses of protons and neutrons shows that the ...

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.

If you were to divide the particles that made up your body into smaller and smaller bits, you'd find that at every step along the way -- at least in terms of mass -- the whole was equal to the sum of ...
