What Happens Inside a Proton?
Season 8
Episode 23
What’s going on inside protons and neutrons? It’s a total mess - an infinite amount of quarks and antiquarks are constantly being created and destroyed. You can’t use maths to predict what will happen. You need a supercomputer! (compare to the spacetime video on cosmic simulations: that is simulations of the largest scales and this is simulations of the smallest scales!)
