How big is the proton? This study and one of the prior studies have the diameter of the proton was about 0.83 femtometers (m). A femtometer is 10^-15 meters. The discrepancy between the size of the ...

For nearly a decade, scientists have been arguing over the size of the puny subatomic particles: extra small, or extra extra small. A new measurement bolsters the case that protons are more petite ...

A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some researchers even ...

Nonconformists could take a page from the proton’s playbook: The subatomic particle is once again resisting scientists’ attempts to size it up. Everyone agrees the proton is tiny: Its radius is less ...

Researchers have recently extracted the proton mass radius from the experimental data. A research group at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) presented an ...

A precise new measurement of the size of the proton shows a decade-long problem may now have a solution. The proton is arguably the most important particle to our everyday lives, forming one of the ...

Protons, among the building blocks of atoms, are even smaller than we thought—and the unexpected discovery may alter some of the most trusted laws of physics. All atoms are made up of nuclei orbited ...

How many protons can dance on the head of a pin? The answer is nowhere near as straightforward as one may think — and it might offer new insights into one of the most well-tested theories in physics.

One of modern physics’ most cherished ideas is quantum chromodynamics, the theory that describes the strong nuclear force, how it binds quarks and gluons into protons and neutrons, how these form ...

In the article “Femtotechnology:Nuclear AB-Matter with Fantastic Properties” American Journal of Engineering and Applied Sciences. 2009, p.501-514. Bolonkin offered and considered possible super ...

Physicists at York University in Toronto have spent the last eight years meticulously conducting a sensitive experiment to measure the charge radius of the proton in hopes of resolving conflicting ...
