1) The earth, like all of the planets, is a charged body.
2) The Sun has an electric field, and it interacts electrically with the planets.
3) The Sun is not powered by some mysterious, internal “nuclear furnace”, but rather externally by electric currents flowing along the arms of the Milky Way.
"Sum up to zero..." or so the astronomers claim... but they have no proof.
"Charged particles move along magnetic flux lines..." Are you absolutely certain of that? Or are the charges separated into charge separated double layers... as we see can form in all plasmas we work with on Earth and that are scalable? Perhaps the magnetic flux lines are there because there are charged particles moving?
What creates your magnetic flux lines? Are they just "there" or are they the artifacts of moving electrons... as are all magnetic fields?
"What powers the sun is still assumed to be nuclear fusion ... " A fusion powered sun does not explain how you get from a 6000º surface to a multimillion degree upper atmosphere by "convection".
"...but that does not hold up..." That's the problem.
