B What’s the necessity of the strong force?

Click For Summary
The strong force is essential for holding protons and neutrons together in atomic nuclei, counteracting the electromagnetic repulsion between positively charged protons. It stabilizes atoms, allowing for the formation of matter as we know it. The discussion raises questions about the role of fundamental forces in energy states and stability, particularly why the strong force exists despite the electromagnetic force's opposing effects. The necessity of the strong force highlights the complexity of atomic interactions and the balance of forces in nature. Understanding these dynamics is crucial for comprehending the structure of matter.

TL;DR
Why does the universe care to have the strong force.
To put it simply: Why do we have the strong force?

If the goal of the fundamental forces (in a heavily generalized sense) is to bring particles to a lower state of energy, how is the strong force participating to this?

Could it be due to atoms being a very stable configuration?
If this is the case why is the electromagnetic force trying to work against a stable configuration?

This question is not a physics question, and cannot be answered here.

Why do you think this is the case?

You have a bunch of protons jammed together in an atomic nucleus, with their positive electric charges repelling each other. What holds the nucleus together?

Thread 'The Power of QM and QFT'

We often see discussions about what QM and QFT mean, but hardly anything on just how fundamental they are to much of physics. To rectify that, see the following; https://www.cambridge.org/engage/api-gateway/coe/assets/orp/resource/item/66a6a6005101a2ffa86cdd48/original/a-derivation-of-maxwell-s-equations-from-first-principles.pdf 'Somewhat magically, if one then applies local gauge invariance to the Dirac Lagrangian, a field appears, and from this field it is possible to derive Maxwell’s...
