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 ...

The whole is equal to the sum of its constituent parts. That's how everything works, from galaxies to planets to cities to molecules to atoms. If you take all the components of any system and look at ...

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 ...

What is the weight of a proton? Scientists from Germany and Japan have made an important step toward better understanding this fundamental constant. By means of precision measurements on a single ...

Only 1% of the mass of the proton comes from the Higgs field. ALICE scientists examine a process that could help explain the rest. When protons and nuclei inside the Large Hadron Collider smash ...

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 ...

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 ...

The smallest named unit in the metric system is the yoctogram, equal to 0.000000000000000000000001 grams. (Yes, that's 24 zeros.) For a scale that can measure differences in mass as small as a ...

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 ...
