The CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed an unforeseen feature in the behaviour of top ...

The NSF-DOE Vera C. Rubin Observatory, a major new scientific facility jointly funded by the US National Science Foundation ...

The Standard Model of particle physics is both fantastically successful and glaringly incomplete. Its predictions have pieced together many of the known features of the universe and guided physicists ...

The hidden neutrino As we experimentally observe them now, neutrinos cannot interact with the Higgs field because they’re are missing something vital: They are not right-handed. Particles can be ...

Yesterday, at the annual Rencontres de Moriond conference taking place in La Thuile, Italy, the LHCb collaboration at CERN reported a new milestone in our understanding of the subtle yet profound ...

Gamma rays are the most energetic type of light, packing a punch strong enough to pierce through metal or concrete barriers. More energetic than X-rays, they are born in the chaos of exploding stars, ...

Symmetry writer Mike Perricone is back again with a round-up of this year’s popular writing related to particle physics and astrophysics. Several notable titles include explorations of what it’s like ...

2. Gravity and weight are not the same thing. Astronauts on the space station float, and sometimes we lazily say they are in zero gravity. But that’s not true. The force of gravity on an astronaut is ...

Round 1: The Proton Pay heed to this smashing subatomic celebrity, used in medicine and to produce neutrinos, antiprotons and, of course, the God particle. Step aside, lightweights. The proton has ...

The particles we meet The radioactivity born inside your body is only a fraction of the radiation you naturally (and harmlessly) come in contact with on an everyday basis. The average American ...

1. Antimatter should have annihilated all of the matter in the universe after the big bang. According to theory, the big bang should have created matter and antimatter in equal amounts. When matter ...

The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and accurate in its predictions. It mathematically lays out the 17 building blocks of ...
