"The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of star stuff."—Carl Sagan Almost ...

Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

DEEP in the heart of every atom lurk protons, tiny particles from which the chemical elements were forged, first in the searing heat of the big bang and then in the nuclear furnaces of stars. The ...

A new super-heavy element, temporarily called 117, may soon be making its way into the periodic table after being successfully created in a laboratory setting. Made up of 117 protons, the element ...

Protons can hold an elementary particle heavier than themselves. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Protons may have more "charm" ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 201, No. 1066 (Apr. 26, 1950), pp. 348-365 (18 pages) The energy spectrum of 4· 5 MeV protons scattered ...

The methods previously described have been applied to a study of the elastic scattering of 4· 2 MeV protons by deuterium, helium, nitrogen, oxygen, neon, argon, chlorine and bromine. The results ...

"With evidence that quarks and gluons are entangled, this picture has changed. We have a much more complicated, dynamic system." 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' ...
