I liked the article too. I don’t understand the part about how the sun could be powered by electrical currents running through the galaxy instead of by fusion. Wouldn’t there have to be a side of the sun where the electricity flowed in and a side where it flowed out? Wouldn’t those areas be much brighter, and wouldn’t there be obvious magnetic fields associated with that current? There should be some polarity that could be measured by satellites or visible whenever there is a CME. I just don’t see the evidence for that.
On the other hand, I do think the sun is very electrically active and teeming with magnetic fields, which cause the corona to be so bright. I just think those magnetic fields are generated from inside rather than outside, but with some evidence, I’d be open to other ideas.
