Bernie do not appeal to heliocentric science for support.. as I show below
Why assume an extra rotation, when the full translation cycle
explains what we see - the same face of the Moon.
The full translation cycle has the same effect as one rotation,
but it's not called a rotation ( I looked in up in Jewiepedia ).
It is not an assumption.. and you should look from above and outside
of the earth, not from the earth. Rotation is a geometric action
which need not involve any material object. Then your pedia is wrong.
But Wiki is not wrong Bernie .. Here is Wiki's specifications for the moon..
You will read it has a synchronous rotation .. equal to its orbit
heliocentrically speaking of course. I highlighted it in brown ...
Sidereal rotation
period 27.321 582 d (synchronous)
Also from Wiki I find this line.. which should convince you.. The axis of
rotation of the moon is not the same as the axis of its orbit... see below.
The mean inclination of the lunar orbit to the ecliptic plane is 5.145°. The
rotation axis of the Moon is also not perpendicular to its orbital plane, so
the lunar equator is not in the plane of its orbit, but is inclined to it by a
constant value of 6.688° (this is the obliquity). One might be tempted to think
that as a result of the precession of the Moon's orbit plane, the angle between
the lunar equator and the ecliptic would vary between the sum (11.833°) and
difference (1.543°) of these two angles. However, as was discovered by Jacques
Cassini in 1721, the rotation axis of the Moon precesses with the same rate as
its orbit plane, but is 180° out of phase (see Cassini's Laws). Thus, although
the rotation axis of the Moon is not fixed with respect to the stars, the angle
between the ecliptic and the lunar equator is always 1.543°.

Why does everything have to rotate? Who said it does..
Plus it sure would be quite a coincidence for the moon's rotation to be such
that
we always only see one side of the moon, Well coincidence has nothing to do
with mechanics,,,,,especially
when the Earth would be rotating also.. and the earth, being stationary or
spinning like a top, would make no difference to the moons facing the earth at
all times.. Not a spit of difference. Phil

It actually also works against heliocentrists because
who could believe their synchronized Moon rotation explanation?
The odds are way against that type of order in an exploding universe.

So the movement of the Moon is a translation, but there
is no rotation. The Moon is fixed within the rotating firmament.

Bernie, look again at Pauls moon and see it orbit.. you will see it
rotate/ Phil

Paul,
Yes, that looks like a fair representation.
"All rigid body movements are rotations, translations, or
combinations of the two."
So the movement of the Moon is a translation, but there
is no rotation. The Moon is fixed within the rotating
firmament.

You said to Philip -- From Bernie Brauer Sat Nov 22

If you go dwon to your local day-care centre ( where
toddlers get dropped off so mummie can go to work to help daddy pay 66%
ALL-TOTAL taxation ) you will see a toy where you can slide a wooden sphere
along a circular thin metal rod. So the sphere is fixed upon the circular rod
and the same point always shows inward.
I have attached an illustration of what I think you have
described but with the small addition of a straight, thin, light, paper tube
attached to the wooden ball so as to indicate visually that it always points to
the centre. The ball -- with the indicator -- is shown travelling around the
circular rod in a clock-wise direction.
Is this a fair representation? Please indicate any
reservations or arguments you may have.
