Anomalous orbital precession of binary systems
The moon/earth binary system exhibits anomalous
changes in orbital eccentricity[1]. Its orbital eccentricity and precession change
in a way that cannot by themselves be easily explained. One explanation refers
to the proposed 2 dimensional (2-D) gravitational field effect of relativistic
frame dragging by the central supermassive black hole at the center of our galaxy.
The short range usually attributed to frame dragging is not relevant to 2-D
frame dragging because the proposed condensing of the black hole 3-D gravitational
sphere of influence to a 2-D entity extends the radius of the frame dragging
effect many orders of magnitude so that it affects the stars and other
co-rotating systems as far out as earth and even farther.
An analysis of data records collected with
the Lunar Laser Ranging (LLR) technique performed with better tidal models was
unable to resolve the issue of the anomalous rate of change in eccentricity
de/dt of the orbit of the moon,
which has a magnitude of de/dt = (5±2)×10-12/yr
Cosmological
explanations fail: none of them are successful in reproducing the effect, since
their predicted rates of change in lunar eccentricity are too small by several
orders of magnitude as referenced above.
Frame dragging declines as around 1/r3 for a normal classic unperturbed black hole, it appears.
But a real supermassive black hole may have
frame dragging declining as 1/r2 or even 1/r. Relativistic analysis should
provide an exact numerical estimate.
This suggests a critical test of the 2-D gravitational field
proposal. The gist of the test is that anomalous changes in orbital
eccentricity and orbital axis of rotation should be detectable in binary stars
near Earth and perhaps even in the orbits of planetary moons such as Mars’
Phobos and Deimos. The Mars system can be considered as a simple binary system
because Mars’ moons are not massive enough to significantly affect each other
and their relative distances are generally too far. And, a three body
gravitational system may be too complex to analyze accurately, so Mars’ system
may be close to ideal.
There may be other candidates for planet/moon anomalous orbital
precession and eccentricity if the obstacle of the many body model of
gravitation could be overcome (with ultra precise measurements and
supercomputer assistance, say). But, all the other planets either have many
moons or else have no known moons (Venus and Mercury). We could put moons
(satellites) into orbit around Venus (say) and track these orbits as precisely
as with LLR.
