Simulation of Venus
and the orbit of Venus
am going to use the orbit of Venus to explain how the orbit-gravity-sim-12.exe
(OGS12) algorithm calculates the effect of gravity travelling at
the velocity of light from General
Relativity. Programming General Relativity is all
about determining the direction of the gravity-origin. This gravity-origin
will be different from the position of the bodies in an orbital
structure due to the velocity of those bodies and the alleged velocity
Binary systems have a large difference between the position and
gravity-origin due to both objects having significant velocity.
But even the comparatively small gravity of Venus has an impact
on the position of the Sun, oscillating it between 6 or 7 km per
orbit at a pedestrian pace of about 86mm per second (which is about
the speed of a tortoise in a hurry).
Now it takes 6 minutes to travel at the velocity of light from Venus
to the Sun. So if gravity travels at the velocity of light, Venus
will be pulled to a point about 30m away from the centre of the
Sun. (0.086 m/s x 360s = 31m). Of course, the impact that the small
gravity of Venus has on the Sun is also delayed. So how do those
tiny amounts change the orbit of Venus?
Scenario  calculates
that according to Newtonian gravity, if Venus is at a distance of
108 940 965.221028km after 1 orbit – then
108 940 965.221242km after 10 orbits – which
is an error-margin of:
214mm over 9 orbits (23 mm per orbit).
 calculates that
with General Relativity Venus is:
108 940 972.276101km at the 10th orbit– which
outward drift, or 784 metres
per orbit after 9 orbits -
due to gravity moving at the velocity of light.
As regards the alteration that Special
Relativity would have on Venus, it is very small,
because Venus has an orbit that is more than 98% circular. The result
is an inward drift of about 40m per orbit, so that in no way cancels
out the outward drift of 780m per orbit from General Relativity
like so many people believe it should.
