If it were true that the actual position of the moon is 2.1 degrees away from the apparent position of the Sun during a solar eclipse, you would think that someone would have mentioned it somewhere.
How this relates to the addlepated observer hypothesis, I haven't a clue.In view of this, we expect that a two-body system such as the Sun and the Earth, which produces almost no gravitational radiation (according to general relativity) should have numerator dynamic effects in the gravitational field that give nearly perfect phase-lag cancellation, and therefore the Earth's gravitational acceleration should always point directly toward the Sun's position at the present instant, rather than (say) the Sun's position eight minutes ago. Of course, if something outside this two-body system (such as a passing star) were to upset the Sun's pattern of motion, the effect of such a disturbance would propagate at the speed of light. The important point to realize is that the fact that the Earth's gravitational acceleration always points directly at the Sun's present position does not imply that the "force of gravity" is transmitted instantaneously. It merely implies that there are velocity and acceleration terms in the transfer function (i.e., numerator dynamics) that effectively cancel out the phase lag in a simple periodic pattern of motion.[excerpt]
