Continued from Orbital Precession topic under Space/Astronomy Questions and Answers thread Ė now closed.
Thanks to Tensor for the figures and recommendations. Now I will try to predict Earthís orbital precession rate. I have to collect some data re the famous Binary Pulsar before I venture there. Once I have completed my calculations, I will report the results.
The new model has three constants: gravitational-wave speed; momentum-field range coefficient; and dynamic gravitational constant. I will explain later the non-constancy of the classical gravitational constant; itís too detailed for the space here.
If any one of you wants to critic my model, please let me know. I donít know the Forum rules well, so I canít attach the paper here. I have become ďblindĒ to the model; someone needs to scrub it.
I used Mercuryís orbital precession rate (575 arc-secs) to estimate the speed of gravitational wave and the static gravitational constant. I agree with you that Venusí orbit is too circular.
P. S. I thought you would like to know what motivated me to finding an alternative to general relativity.
1. Many physicists quote 43 arc-secs as predicted by GR and also as the observed value. This is just incorrect. If the space-time around Mercury is warped, it is warped (period). GR should account for the total observed precession (575, 5600, or whatever arc-sec/century). Maybe GR does and I donít know about it.
2. GR predicted the gravitational deflection of light at the sun to be 1.74 arc-secs. The 1919 expedition reported its confirmation; Prof. Poor of Columbia clearly refuted it and became an outcast. Later expeditions reported figures from 2.2 to 3 arc-secs. I am not aware of any observation replicating the GR predicted figure of 1.74 arc-secs. I doubt that the non-gravitational effects of the solar atmosphere could be ascertained. The solar atmosphere is especially violent to electro-magnetic waves!
3. How come a gravitational interaction, which is 10**40 times weaker than an electromagnetic interaction, can generate gravitational waves propagating at the speed of light?
4. I doubt that gravity can be unified with the strong, the weak, an electromagnetic forces by clinging to GR. (I would be wrong if gravity were too unique to be unified. It may be not necessary to unify gravity with the three fundamental forces.)
These reasons have motivated me to find an alternative. I want to try mass (gravitational charge) and momentum (gravitational current) properties of matter and the associated mass field and momentum field respectively. Mass-momentum field is similar to start with but different further down. A noteworthy difference with electro-magnetic field: Whereas a probe moving with a charge detects the charge field but no magnetic field; a probe moving with a mass detects the momentum field but no mass field.
