I love these videos! I really regret never taking physics in school, and I'm now just studying it by myself.

Thank you so much.
Now I understood why the atomic nucleus doesn't explode.
There's a very powerfull force that keep the protons together.
The gluons are stronger than magnetic repulsion between the protons.

They have to hold them stronger than electromagnetism, otherwise the positive charged protons would repel one another
