A new measurement finds the universe's teensiest particles weigh no more than one-millionth the mass of an electron.

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not ...

Researchers at the CMS collaboration at CERN have reported the discovery of the smallest hadron in existence, the toponium.

As if atoms weren’t already mind-blowingly small, never mind subatomic particles, CERN researchers in the CMS Collaboration ...

In just the first 259 days of data collection, KATRIN, a beta-decay-based detector in Germany, has set the smallest upper ...

Quarks are the reason protons have a positive charge. Each quark has a fraction of an electric charge. A proton has two up ...

A new estimate of the ghostly particle’s maximum possible mass brings physicists a tad closer to understanding the universe. By Katrina Miller Katrina Miller studied neutrinos in graduate school ...

Though you may be pretty certain just from looking about the place that we are living in a three-dimensional (plus time) universe ... a black hole prevents any particle or form of radiation ...

Can space and matter be infinitely divided, or is there a fundamental limit to smallness? This video tackles Zeno’s paradox, the concept of indivisible particles, and explores scales so tiny they ...

This is important because the neutrino, as the most abundant particle in the universe, "weaves a thread that connects the infinitely small and the infinitely large," Thierry Lasserre, a physicist ...

More than 13,500 scientists who have worked on experiments at the Large Hadron Collider (LHC), based in Geneva, Switzerland, have been awarded the ...
