Query: Is there a Gravitational Thomas Precession ?   Gravitational Thomas Precession (GTP) is the name given to Thomas Precession
when the acceleration is caused by a gravitational force field. The contributio
n of the GTP to the the anomalous perihelion advance of the orbit of Mercury is
here estimated at $\dot{\tilde{\bf\omega}}_{GTP} = 21\cdot49 [ 1 + \frac{(\vec
L \cdot \vec S)}{L^{2}} ] {arcsec/century} $,where $ \vec L $ and $ \vec S $
respectively represents the orbital angular momentum and the spin angular
momentum of Mercury .This effect seems to be of some serious concern for the
General Relativity.
