Mozina argues that the gas model, started by Galileo and which persists to this day, really only holds true for the first 4800 km into the Sun. Below that is a solid "surface" made of iron.¹ He calls our attention to the first images produced by the SDO satellite, where there is a definite darkening at 4800 km below the limb. The filters have since been adjusted to eliminate this, but Mozina believes that the engineers had the instrument calibrated correctly to start, and that when they found a distinct density gradient that wasn't supposed to be there, they challenged the wrong assumption — it wasn't the instrument calibration that was wrong — it was the gas model.
