A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most ...

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible. Tachyons are a ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

Plasma, the fourth state of matter, consists of a gas in which electrons are no longer bound to atoms, which allows ...

Black holes could be a hologram. In fact, the entire universe could be a hologram. At least, that's one part of the idea behind a recent study published in the journal PRX Quantum. The study is a ...

Measurement of W boson particle mass confirms Standard Model of physics and reignites the search for other particles.

Scientists have made a particle physics discovery that they say could mean nothing less than the upheaval of our entire model of the building blocks of the universe—if their results can be ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

Ah, dark matter. Creator of the universe, sculptor of galaxies, great brewer of coffee (probably). There seems to be nothing it can’t do, or isn’t responsible for, but there’s just one problem: Where ...

On December 6, 2016, a high-energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts (PeV) of energy. Deep inside ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science’s most successful theories, hinting at unknown forces or quantum objects. Now, an ...
