Eric Mack has been a CNET contributor since 2011. Eric and his family live 100% energy and water independent on his off-grid compound in the New Mexico desert. Eric uses his passion for writing about ...

Asymmetry in the proton confounds physicists, but a new discovery may bring back old theories to explain it. Symmetry — displayed in areas ranging from mathematics and art, to living organisms and ...

According to theoretical predictions, within a millionth of a second after the Big Bang, nucleons had not yet formed, and matter existed as a hot, dense "soup" composed of freely moving quarks and ...

Astronomers have found two collapsed stars that they say appear to be made of free-floating quarks, an exotic form of matter whose existence has been theorized but never before seen. If confirmed, the ...

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain ...

Quarks are elemental particles, with no sub-structure. Understanding them is crucial to learning how physics works on the smallest levels. By studying collisions of incredibly small particles made up ...

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...
