I am still not convinced of this. And although it clearly exasperates you, your exasperation is not a credible substitute for actual...

What you are really measuring, if anything, is whether a (rigid) object retains the same proper length when rotated in a gravitational...

Speed isn't a well defined measure in curved spacetime. So the answer is yes or no, depending on your coordinate choice.

If the OWSOL is anisotropic then increasing the distance does not help. It gives a longer time for a smaller error to accumulate. The...

And I think it's fair to say that Eddington's prestige precluded any real review of the results at the time. They were just accepted.

Probably. But, it gave the newspapers a great headline!

Unfortunately, in Eddington's day it was not common to report experimental errors. So you may need to look at more modern experiments...

An alternative approach is to just write the most general affine transformation between inertial frames and determine the coefficients...

In Anderson coordinates the expression of the flat spacetime metric ##ds^2## includes mixed term in ##\kappa dtdx##. For ##\kappa=0##...

Yes, so I think I need to go back and be more careful with both equations 4 and 6. I will try to do that sometime later this week

This will be true in general for any transformation between the Schwarzschild chart and a chart that doesn't have a coordinate...

Yes. Also, any four-velocity is a 4D tangent vector to a worldline. So that vector is the same vector in different frames, although its...

Which, incidentally, means that "locally flat" is a bit of a misnomer. The analogue in spherical geometry is that you can lay your...

Playing around with this a little more, it looks like this only works for ##r<R## inside the horizon. For outside the horizon with...
