“LOL True it doesn't directly measure the gravitational pull of the Sun, I never said it does. Do you have a nice simple experiment that does? I would be very interested in seeing it. I might even pay you money for it.And just how do you know where the Sun is to illustrate its actual position?
The experiment does illustrate the difference between the actual and apparent position of the Sun and that's all that that matters : )”
I will confess that I am making certain basic assumptions. I am assuming the speed of light is correct, that the distance to the Sun is correct, that Light travels in a straight line, that geometric models and math actually apply to the real world, etc, etc.
All of my experience has shown me that the above assumptions are relatively accurate, at least way beyond any accuracy that I need : ) Do you have a problem with any of those assumptions?
