You keep trying to turn this back into a three body model. The Sun is only 2.1 degrees behind strictly in relationship to an observer on the earth, in a two body model. In the two body model there is essentially no difference between two stationary objects with one of the them spinning or having one of them orbit the other object. Adding a third body invalidates the two body model.
Let me see if I get this straight. If we set up your original light-angle and gravity angle detectors on the earth, you're saying they'll read 2.1 degrees apart. But then what - as soon as we add a gyro, wallah, suddenly the gravity angle meter and light angle meter snap into harmony, both pointing the same place?

488 "In a two body system there is no difference between one body spinning in relation to the other body or one body orbiting a stationary body"

Foucault's Pendulum."
By the way, a gyro is a great way to see whether the sun is orbiting the earth at 2.1 deg/8.5min or the earth is spinning at that rate. Now you know this being a pilot I'm sure, but in any case I've a good friend who's an FAA certified aircraft instrument repairman. He's in his 70s now and still working, and he's really good at it. Anyway, he repairs and adjusts gyro heading compasses and he tells me that a perfectly adjusted compass will drift due to the earth's rotation (Except on the equator, if I recall correctly.) And this is exactly what makes sense.
Now here's one for you! Just thought of this one. The
Ring Laser Gyro is a gyro that uses the speed and interference of light to measure its rotation
without any moving parts.
In other words, even in a 2-body situation, with laser ring gyros on each of them, one could tell which body was orbiting which!
How's that one!?
Remember this is all based on mrjesses merry go round model. I would like you to explain to me how to determine in a two body model how you can definitively determine which body is orbiting or which body is spinning?
Here's how you can definitively determine which body is orbiting and which body is spinning: Bury a Laser Ring Gyro 10 feet deep in each body, protecting of course from environmental harshness. If a body is spinning, the ring gyro will tell just how many degrees per second. Simple as that! Can't hardly say that adding a Laser Ring Gyro is adding a third body either, since it has no moving parts!
I think this is where you are confused.
ECO's not the one confused here, by the way. I'm feeling fine too, in that regards.
In the end, are you going to tell me something along the lines of "Oh, yeah, I know I was wrong. I was lying to you the whole time as a favor to you. I knew you wouldn't go look stuff up unless I challenged you and so I figured lying to you was the best way to do that. Now you're smarter." ???
I just can't figure out how somebody could be so wrong, with so much free information available, and not realize that they were wrong. But I digress.
By the way - how about the Laser Ring Gyro? Wouldn't that definitely determine who was spinning and as a result who was orbiting?
Thanks,

I just want to be clear, when you look up into the night sky and aim a telescope at Saturn, do you really believe that Saturn is exactly where you are pointing the telescope?

The Gyro, LRG and pendulum are essentially the same thing and if you add them in you are adding in a third body and unnecessarily complicating the model. Generally, the best way to understand something is to keep it as simple as possible.
