"What force could drag the Sun around the Earth? Talking about coordinate systems and general relativity and the tides doesn't answer this question, it avoids it."

The fact that you keep asking this question shows that it is impossible to discuss the issue with you. It is the wrong question. GR and coordinate systems is exactly the right answer, as Einstein, Hoyle, Born and Ellis have made clear.

You simply don't understand. I can't fix that.

A coordinante system doesn't explain what is causing the movement through the coordinates. You obviously cannot answer the question because nothing we have any experience with COULD exert force upon the Sun to move it around the Earth while leaving the Earth motionless. It must be magical forces, that idea has a long and storied past, but it isn't Science.
