Equilibrium and Ham examinations
I know books say a lot of things but do they explain WHY current
cannot flow thru the center?

If you do the differential equations, it doesn't say why the center
can't so much as why the skin does. Similar to gravitation and water
flowing downhill vs uphill.
My understanding was about molecular alignment and that the flow of
electrons would be there first. Notice that stranded wire is often
preferred for it's current handling ability even though solid is easier to
terminate to and doesn't have the problem of discontinuities due to
corrosion on many surfaces that rub together.
This doesn't mean that eddy currents aren't there in hollow elements. Solid
or stranded or hollow tubing, the eddy currents contribute to loss but don't
contribute to radiation.
Ejection of particles should lead to deterioration of the metal but if you
were to coat the elements (with non-conductive and non-reactive coating)
there would be no deterioration. It would also prevent rain static.
I don't burden myself with paradigms to explain electromagnetic wave
propagation in free space. It and Gravity do very well without my
explanation. We know that the AC current in the antenna induces an
electromagnetic wave is sufficient for my purpose. Unless I can find
funding for renewed efforts... (wink nudge)
