Physicists have set a new upper limit on the mass of neutrinos. And the finding could poke a big hole in the Standard Model of particle physics. When you purchase through links on our site, we may ...

What is the Stokes-Einstein Equation? The Stokes-Einstein equation is a fundamental relation in physics that describes the diffusion of spherical particles through a fluid with low Reynolds number. It ...

We explain how The Standard Model of particle physics works! The Standard Model of particle physics is arguably the most successful theory in the history of physics. It predicts the results of ...

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 ...

Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot ...
