Tony:

Did you read my post #33, above? Is there something there that you didn't understand?

Here's a link to some of the relevant maths. You can do the calculation yourself and tell us your result:

You're unable (or unwilling) to explain what you meant? Okay. I'm not surprised.It’s hard to imagine that this is the question James R asked. Oh my god.

Yes. We know that Newton was wrong. We have, for instance, detected gravitational waves.You should know how Newton's gravity equation is written. It is only related to the mass of objects and the distance between them. This is a force acting at a distance. Laplace did calculations and found that the gravitational speed was 7 million times the speed of light.

Is it relevant to what we have been discussing?Do you want to see what Academician Shiing-Shen Chern said about Einstein and his theories?

Why don't you tell us?To answer this question, you need to first answer the following question: In which direction is the space-time around the sun curved? I can give you some reminder: the space around the sun is 3D.

__Riemann curvature tensor__Don't tell lies, Tony!What are the facts? The theory of relativity is useless and cannot even calculate the simplest planetary orbits.

Yes. Without correcting for time dilation effects, the GPS system would not be able to locate objects on the Earth with the accuracy that it demonstrably has.If I ask you, does GPS need to use the theory of relativity? You will tell me firmly that this is necessary. But is it really necessary?
