The orbital eccentricity is 0.0167 (look it up).
Earth's semi-major axis is about 149,500,000 km (look it up).
Earth's semi-minor axis is therefore 147,003,350 km
Perihelion (of the Earth-Moon barycentre) lies on the semi-major
axis at zero degrees. Any other point in the orbit is further from the Sun.

The difference between semi-major and semi-minor axes is 2,496,650 km,
and by dividing that by 90 degrees, about 27,740 km per degree (not linear,
I know, and the 90 degree point is not on the minor axis because the sun is
at the focus, not the centre of the ellipse, but close enough).

Thus at 1 degree either side of zero degrees on the major axis, the
barycentre
is about 27,740 km closer to the centre of the ellipse but further from the
sun.
This places the Earth's centre (at one degree with the Moon at full) closer
to
the Sun by 4,600 km or at about 23,000 km further away from the centre of
the ellipse than at perihelion.

So when pompous shitheads like Schlyter, who talks about "idiots that
don't listen" and Dave W. who "doesn't have time to teach me celestial
mechanics" (none needed, this simple trig) are asked to prove their claim,
they wave their hands and it exposes them for the fucking frauds they are,
relying as they do in their blind faith in a table someone produced and got
his sums wrong, and all I've done is asked them to prove it.

Now, having said that... it is possible that I've made an error since I've
approximated, but there is NO WAY that those dickheads are capable
showing it.

Why did Einstein say
the speed of light from A to B is c-v,
the speed of light from B to A is c+v,
the "time" each way is the same?
