Do you thin that, If the Sun and Earth were perfectly motionless in space, except the Earth was rotating 360° every 24 hours, would (at high noon, sans the atmosphere) the optical image of the Sun be lagged 2.1° behind its gravitational pull?

Yes, up to 2.1 degrees.

“Yes, up to 2.1 degrees.”

Would you be willing to draw up the math and geometry that supports this claim?
