Studies show that changes in earth’s orientation relative to objects “inside” the SS (i.e. Sun, Moon, Venus, etc.) are negligible (less than an arc second or two p/y), whereas changes in earth orientation relative to objects “outside” the moving frame of the SS (fixed stars, quasars, etc.) are over 50´´p/y. In fact, rotation time equivalence studies and lunar studies show the earth hardly “precesses” at all relative to objects within the SS.

Most astronomers acknowledge this in practice by using a non-precessing tropical frame to locate objects “inside” the SS, whereas they require a precessing sidereal frame (or T[J2000]+PxY) to find objects “outside” the moving SS.

Rotation-Time Equivalence


“Journal of Theoretics” Time Equivalence of the Tropical Year and the Sidereal Year, Uwe Homann

Our Lunar Calculations effectively show the same thing. The earth may experience nutation and minor short term effects but it does not appear to precess 50”p/y relative to objects within the frame of the moving solar system. This means that the change in earth orientation measured relative to VLBI reference points must be principally the result of frame change or solar system motion.

Precession Riddle

If there are 50 arc seconds of earth wobble in 365.2563 spins of the earth then how much wobble (precession) is there in 365.2422 spins of the earth? Please take a moment to calculate your answer before reading on.

Logically, if the earth wobbles 50 arc seconds in 365 days, 6 hours, 9 minutes and 9 seconds (a time period equivalent to a sidereal year) then it should wobble 99.99% of this amount in 365 days, 5 hours, 48 minutes and 46 seconds (a tropical year time period). But because the cause of precession has been misdiagnosed – the lunisolar theory has no way to logically answer the question – so the question becomes a riddle. Precession is the value of the delta between the two years.

The best answer under current lunisolar precession theory has to be: there is no wobble in a tropical year but for the next 20 minutes after that - the earth wobbles a full 50 arc seconds! The answer under the binary model is simple and logical: The earth does not wobble but it does change orientation to objects outside the solar system as the solar system curves through space. In the time period known as a tropical year it has curved through space 99.99% of the 50 arc seconds (of precession) found in a sidereal year. Therefore the phenomenon known as precession can only be due to the changing orientation of the solar system as it curves through space – it has almost nothing to do with a local wobbling of the earth.

Footnote 1: In a paper found in the Astrophysical Journal the authors claim to have measured the motion of the solar system concluding that it probably only curves about .005 arc seconds per year, allowing it to move once around the galaxy in about 240 million years. In spite of all the fancy words, the unstated assumption is that the delta between a sidereal and tropical year is due to a local wobbling of the earth (a.k.a. lunisolar precession theory). If the authors understood that there is very little local wobbling, they would then find 50 arc seconds of motion per year that needs to be accounted for.

Footnote 2: Remember precession is the delta between the tropical and sidereal years – the tropical year doesn’t have it – whereas the 50 arc second longer sidereal year has it.
