    You're having quite a conversation with your self. I haven't bothered to read any of.

    I am actually not talking to myself, or strictly for myself, but responding to ideas that pop up here and on other sites on the subject.
    Taking a sidereal view, interesting things have to happen, when with these epicycles, cycloids, matter on planets, even moons appear to slow down, come to a halt in "fixed" space and even reverse, appear to retrograde.
    so, while you were a stellar contributor in the past, thank you, please take the sidereal, stellar view once in a while; For the last word might not have been said on this.

    Origin, good and lucid question!
    No, but from that viewpoint only the equator at noon and the Moon Europa, not the whole planet, would be near a standstill or being retrograde, because the Orbital and Rotational velocities are so closely matched but working in opposite directions.
    In these, and Saturn's data, the equation (Vo:Vr) =~ 1 ! , so: the zero velocity zone is near the planet surface. Harder to visualize is

    The Earth to Moon situation where Vo: Vr is a ratio of 64:1, but multiplying that by the Earth radius of 6370 km gets you 407 744 km4 which is near the Moon apogee of 406 700 km, different at different times of course still,
    During an eclipse like 2019, 2024, The Moon is in a zero velocity position. with respect to the Sun/stars. how? as in a cycloid,
    Considering the Earth being the hub, the Moon affixed to the rim, our satellite will be at zero velocity when making contact with the road, the Sun/orbit,ecliptic.
    The only point in the system at rest in such a way.
    again and again.
    NASA and Mr. Bezo's, Blue Horizon promise to have a woman on the Moon by 2024. ,

    Anybody suggesting an experiment to falsify this alternate theory at that occasion?
    while watching the shadow of the Moon moving across North America during that April 8 Lunar night?

    Just a note on my monologue here: have brought a NASA proof into this, (I think there is even a relevant partial Dione image moving against the Saturn background.)
    On Saturn, if the Earth Moon would be put there at it's original orbital radius, it would have a orbital velocity that closely matches the orbital velocity of the parent planet Saturn, namely ~ 10 km/sec. see "Doing the Numbers on no.1" below.

    I do not understand what you mean, by "meet" -- how? match perhaps?

    Look at the direction of both rotations. As we face the Sun, we move retrograde. the Sun prograde (in a planetary sense we always look at the nightside of the Sun)
    Sun rotation, at Equator, 2 km,/sec. Earth rotation .5 km/sec. Earth orbit around sun 30 km/ sec.
    Where it all meets is in the lunar revolution, 28 days, close to the Suns rotation, ( dealt with in the thread "Doing the Numbers on No 1. )
    You probably will not find a matching number of km/sec. until into the Kuiper belt or Ort cloud. or the outer Moons, Ours is 1 km/sec.

    When I see banded pictures like that, I wonder whether the differences in surface speed in the stellar reference frame have anything to doe with it. The shear that would result from near standstill at the mid day equator to 10 km/s velocity at the poles and double that at midnight.

    just a reminder, in the upcoming opposition observations of Jupiter, please note:
    The rotation of the cloud bands at the equator is only 8% slower than the forward movement of the planet. Nearly cancels as the OP states.
    If Europa, or it's shadow) is anywhere near transit, it has the same orbital velocity retrograde view, as Jupiter forward motion (13.7 km/sec.) . almost at standstill at noon with the clouds, the Red Spot. so:
    zero velocity zones in you field of vision.
    Zero velocity zones defining a common field, like all rolling tires in the world touch the earth at zero velocity, thus define the global surface. mostly, kind of.

    Earth being in the zero velocity zone of the Moon,
    Equator clouds of Jupiter in zero orbital velocity around the sun
    Europa at perihelion at zero velocity around the sun; as seen Friday to Sunday. great views! so,
    when apparent orbital speed drops to zero, like in the above cases, in the speed formula, what happens to the value for time?
    Does it not touch the fundamental value?
