Universal Precession Law (UPL) Applied to Mercury

For Mercury, as for all solar system planets, two experimental precessions are recorded in the literature: 1) the observed total precession of 27.88 microradians per earth orbit and 2) the precession of 2.090 microradians per earth orbit which is usually attributed to non Newtonian effects. The mean Newtonian orbital velocity of Mercury is 4.74 ten power four metres per second,and the mean orbital radius is 5.79 ten power ten metres. using the universal law of precession, the actually observed experimental precession of Mercury is explained by an angular velocity of frame rotation of 6.20 microradians per second due to the underlying spacetime torsion. The non Newtonian part needs an angular velocity of frame rotation of 1.59 microradians per second. For comparison, the experimentally observed precession of the Hulse Taylor binary pulsar is 0.0738 radians per earth orbit and as in the preceding note needs a angular velocity of frame rotation of 5.65 milliradians per second due to the underlying spacetime torsion. The binary pulsar needs an angular velocity about a thousand times greater than Mercury. I will write this up in the next note and will give enough data to calculate the angular velocities for all the planets. This can be done by computer algebra. The universal law of precession is:

delta phi = (2 pi / c squared) ( v sub N squared + 3 omega squared r squared)

where v sub N is the Newtonian orbital velocity of the object at a given point r in its orbit, and omega is the angular velocity of frame rotation.
