I think it’s kinda interesting that there’s a whole universal force that kinda goes uncommented upon in popular physics. I also don’t know anything about the strong nuclear force, but I heard someone say once that it’s actually just electromagnetism on a small scale? If there was, like, a good documentary that centers the history and experiments that lead researchers to conclude the existence of these things, that would be helpful. Being able to situate research in historical context really goes a long way to getting my head around a concept.
I’m not 100% certain but I believe that the Weak Force is why the Four Fundamental Forces of Nature are sometimes referred to instead as the Four Fundamental Interactions of Nature. I believe it involves a neutrino combining with a neutron to create a proton, electron, and antineutrino, with the overall result manifesting as nuclear decay due to the instability from the change in nuclear charge.
The Strong Force isn’t electromagnetism. EM force is what causes like-charged particles to repel each other. Protons are all positively charged, so one would expect them to repel each other, which would prevent atomic nucleii, and thus matter as we know it, from forming. But when protons are close enough to one another, the Strong Force overcomes the magnetic repulsion and the protons instead bind tightly together.
