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 ...

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 ...

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 ...

HEISENBERG has discussed the hypothesis that the nucleus of an atom is composed of neutrons and protons only, the neutron being regarded as a fundamental entity and not as a combination of an electron ...

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 ...

Adding a single proton to a doubly magic isotope of oxygen is enough to significantly alter its properties, an international team of physicists has discovered. Led by Tsz Leung Tang at the University ...

OAK RIDGE, Tenn. — Examining the smallest parts of the universe often takes the biggest kinds of equipment. At Oak Ridge National Laboratory, a unique piece of equipment the size of a building is ...

Neutron stars are the remnants of violent supernovae, all that’s left behind when a star tens of times the mass of our Sun ends its nuclear fuel-burning life. These extreme objects pack more mass than ...
