Mercury year after year always arrives in a different spot than astronomers predict from usual calculations that are always accurate for all the other planets.
We aim to provide an explanation for this anomaly.
New Gravity suggests that Newton’s gravity is a direct pull on space, not an attraction between masses. Thus streams of space head towards the origin of the gravity and any material in those streams follows the flow. Mercury is of course the closest planet to the sun. It is also the smallest planet. This means it is more vulnerable to small changes in gravity than more distant and larger planets. What variations?  The sun as we know spins.
So 1 spin is one spin isn’t it? Yes but the speed at the equator is greater for each spin than it is at the poles.  This jerk or extra twist carries on forever.  The variation is created as the slant of Mercury’s orbit changes in relation to the Sun’s equator.  Additionally ejections of mass from the sun are also more of an influence on Mercury than much more distant planets.
Now that it is known that the only source of anything is empty space a tiny proportion of which moves to provide all the energy and also make from it all material that exists all laws of science should acknowledge and incorporate this fact. The universe is not expanding and is exactly the same size as always. The redshift of light from the more distant objects is caused by extended travel against the pull of gravity, not expansion.
The spin of the Sun provides the additional momentum the additional momentum to add to the normal gravitational pull of the Sun on Mercury.  Thus we hope explaining the constant
difference from expectations every year.
