But I think this is a very interesting subject. Is the problem with the Sun related to the physics of bubble formation? Or nonlinear turbulence in plasma? Would be an interesting maths exercise to speculate.
The big mystery is why does the sun cool millions of Kelvin as it approaches the Photosphere to as low as 3800K and then reheat in the Corona back up to millions K again?
IT seems that the heat of the suns nuclear core plays out and the vast majority of the heat of the sun comes from some kind of magnetic/electrical energy of some kind in the Corona itself. Whatever the Corona heat is, without it I wonder what our Sun would look like.
