All good and true in general, but if you ignore red flags and get suckered by a sociopath, you can end up having a life-changing bad time. Trust, but use your discernment!

Thank you for that clear description - best one I've read yet.

How well do we understand why the constraints that govern this are in place?

For instance, what determines the behavior of the forces? Why must color charge be conserved?

(It seems to me there are two levels of knowledge - the first is, what happens, the second, deeper - what makes it happen the way it does. I'm curious how deep into the latter physics has been able to reach).
