Deep within the atoms that make up our bodies and even within the protons and neutrons that make up atomic nuclei, are tiny particles called quarks. When you purchase through links on our site, we may ...

For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic particles. Symmetry in physics basically means that some rules of nature ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

A view inside a proton moving at nearly the speed of light toward the viewer with its spin pointing horizontally shows differences in the spatial distributions of the momentum of up (left) and down ...

The discovery of two entangled quarks at the large Hadron Collider is the highest-energy observation of entanglement ever made. When you purchase through links on our site, we may earn an affiliate ...

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' ...
