Subj: UFT 375, section 3, part 1This is the first part of section 3 investigating the S2 star system. It
is a system of “weak relativity” as pointed out by other researchers
too. The fluid spacetime model for retrograde precession is new and
origninal. I think its physicals basis has already been founded by note
376(1). There is a rotation period of about 20 000 years of the “central
spacetime disk” which perhaps is related to the oscillation of the solar
system with 26 000 years. I did not mention this in the article but at
least the numbers give a consistent picture, if retrograde precession is
true.The section about the HulseTaylor pulsar is still missing, but this
preliminary version is certainly worth an immediate publication.Horst
partial X double dot / partial X = (partial X double dot / partial t) (partial t / partial X double dot)
and similarly for Y. That introduces a time dependence. The solutions of Eqs. (30) and (31) must also obey Eq. (32). To obtain the simplistic approach is another very good result.

Subj: Re: 376(1): General Theory of Orbital Precession in Fluid GravitationI cannot read the second line of eq. (12), there is a manuscript problem.
Eqs.(3031) are selfcontained (2 eqs. for 2 variables), one cannot add a third equation to these. However one can solve the space dependence of (32), obtaining two space fields X dotdot (X,Y) and Y dotdot (X,Y). If these are inserted into (30,31), we get two algebraic equations for X and Y but no time dependence. Perhaps one has to go back to the field equations directly.Horst
PS: my simplistic approach of my last email seems to come out when setting R_X = X, R_Y = Y.

This note introduces the richly structured field equations of ECE2. In general, precession is governed by simultaneous solution of Eqs. (18), (19), (21), (22) and (29) to give the orbit. In the limit defined by Eqs. (33) and (34), simultaneous solution of Eqs. (30), (31) and (33) may be enough to give precession by adjusting the parameters a sub X and a sub Y, defined by Eqs. (27) and (28) in terms of Cartesian components of the tetrad and spin connection vectors. These are of course missing from special relativity (flat Minkowski spacetime with no curvature or torsion) and its Newtonian limit, but exist in ECE2 relativity (spacetime with finite curvature and torsion). In my opinion the discovery of retrograde precession in S2 is very important because it signals the end of EGR. Leading astronomers dealing with S2 have abandoned EGR (see paper posted on this blog from the Bogoliubov laboratory and co workers). This type of general ECE2 theory can be applied to any problem considered by Einstein. This task has been has been initiatyed in UFT313 to UFT375 to date. The computer may be able to solve all four field equations (8) to (11) simultaneously for gravitation and also electrodynamics, using Cartesian coordinates, or any coordinates.

Subj: Re: Plans for UFT376Concerning fluid dynamics models, my simple approach for the orbital velocity was
r dot –> r dot – v_f bold.
In preceding papers I had used v bold with a plus sign, but then we have the strange situation that retrograde precession goes into direction of negative v_f. With the above change it becomes clear that v_f impacts the precession in direction of v_f. In particular, if the body is at rest in the surrounding medium:
r dot – v_f bold = 0,
we have the usual Newtonian case of a body at rest. Therefore the above approach seems to be the right one.
My use of a rotating vector field v_f is a model for a rotating rigid “spacetime disk” around the central mass. This is a nonrelativistic approach, but I checked the disk tangential velocity at the apastron of the S2 star, it is some thousands of kilometers/s, far below light velocity. A correct description would require something like the LenseThirring effect, perhaps worth a thought in later papers. I will describe now the detailed numbers in section 3 of UFT 375.Horst

In UFT375, Horst has already succeeded in describing retrograde precession using ECE2 fluid gravitation, which refutes EGR. I think that UFT376 should build on this breakthrough by introducing the field equations and spin connection. I should also continue with a literature search to see if I can find some more retrograde precessions. There is also a need to investigate exactly what is meant by strong field and weak file gravitation. However for S2 like stars, weak gravitation is perfectly adequate.
