The sun is doing the twist

The controversial of why the sun is so hot gets a revisit.

The issue is that the outer layers of the sun are hotter than the surface. There have been many theories to explain this and even quite a few papers claiming to have solved it. But the issue has never been cleared up satisfactorily. Now along comes a new piece of work. Solar tornadoes have the potential as conduits for transferring heat. These twisting bundles of magnetic field appear all over the sun and are big and frequent enough to possibly solve the issue. As to whether this clears or muddies the water, let’s wait and see.
