Extremely massive fundamental particles could exist, but they would seriously mess with our understanding of quantum mechanics.
mass
Imagine a particle. What comes to mind? If you aren’t a theoretical particle physicist, chances are you picture a tiny ball, bobbing in space. But that’s not quite correct. One way to prove it: Try to imagine that tiny ball as a particle with no mass. If a particle has no mass, how can it exist?
In this 8-minute video, Don Lincoln explains how, conceptually speaking at least, there are two kinds of mass — gravitational and inertial — and how the relationship between the two has huge consequences on our understanding of the universe.
You’ve got your pole masses, and you’ve got your MC masses. DZero recently measured the top quark’s pole mass. Read on to learn the difference.
The Higgs field gives mass to elementary particles, but most of our mass comes from somewhere else.
A possible explanation for the lightness of neutrinos could help answer some big questions about the universe.
