1. The sun has a (weak) magnetic field that affects how its gas moves, which we don't fully understand. 2. There is a Coriolis force all the way down to the center of the sun, which makes the gas move in weird ways. 3. As a sphere of fluid, the sun supports vibrational modes that we are only just beginning to understand. (See work by e.g., Conny Aerts) 4. We can't really see into the sun’s interior, although understanding the vibrational modes will help.
