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

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 ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. One of the biggest questions in particle physics is whether the ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

A subatomic particle called the W boson may be heavier than expected, a surprising finding that might lead to a shake-up of physics' grand model of how the world works on the microscale. When you ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

The grand explanation physicists use to describe how the universe works may have some major new flaws to patch after a fundamental particle was found to have more mass than scientists thought. “It’s ...

The W boson is heftier than anyone expected. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. An ultraprecise measurement of the mass of a ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...
