And I think that answers my question completely, though it brings up
another one (of course): As the forces increase in strength, they
decrease in effective distance. But that's backwards with the strong and
weak nuke forces? If so, why? I understand that it's gotta be really
hard to hold protons anywhere close to other protons, but it just doesn't
seem elegant or symmetrical (I know, I know, asymmetry is out there big
time, but ...)
