Of all the subatomic particles that have any mass at all, the neutrino is the lightest by far. In comparison, the electron, itself a quantum featherweight, has a mass that is at least 500,000 times ...

The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

Scientists are only beginning to understand the laws that govern the atomic world. Before the 1950s the electrons, neutrons, and protons comprising atoms were the smallest confirmed units of matter.

COLLEGE STATION, -The sun not only radiates light all over the place, but it also emits millions of tiny invisible particles called neutrinos. A team of Texas A&M University physicists has reported in ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

A wild theory suggests that consciousness may explain quantum mechanics, by forcing the subatomic particles to choose one concrete outcome. When you purchase through links on our site, we may earn an ...

The latest news on a newfound particle that turned up last year at the world's largest particle accelerator will be announced at a conference beginning Saturday in Italy. The big question on ...
