A proton’s valence quarks (blue, red, and green), quark-antiquark pairs, and gluons (springs). Scalar gluon activity (pink) extends beyond the electric charge radius (orange) that surrounds the ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the ...

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 ...

Discover how the yoctogram scale utilizes carbon nanotubes for unprecedented mass measurement accuracy, including the mass of a proton. : carbon nanotubes. Carbon nanotubes are tiny---though not quite ...

A heavy, strange cousin of the proton has been seen a second time, but it seems to have lost a little weight. The omega-b-minus, also called the omega-sub-b baryon, is a three-quark particle related ...

Are the fundamental constants really constant? Recent investigations have shown that one essential fundamental constant -- namely the mass ratio of protons to electrons -- can have changed only by a ...

July 21 (UPI) --A team of scientists from Germany and Japan have recorded the most precise measurement of a proton's mass. Researchers accomplished the feat by trapping a proton in a super sensitive ...
