Michelson-Morley Experiment
It (done in air) is nonsense. In air, light is propagated at c/n. So, the result of M-M experiment (done in air) is only natural.
In a book "Theory of Relativity" by Pauli, W 1958, it's written as follows (quoted from English version ; in 1-6). "Rather should one say that for an observer moving with medium, light is propagated as usual with velocity c/n in all directions".

To 46, About latter part of your post, how about the scenario as follows ?
On the moon's surface, a passenger car is moving (in x direction). From a light source placed on the center of ceiling, light rays are emitted radially and symmetrically (in ten degrees increments). And on the floor, spots of light are reflected.
To an observer standing on the moon's surface, speed of light must not be constant.

Inertial Force and Gravity are Different Things
1) For inertial force, space is homogeneous isotropic. Gravity is not.
2) For inertial force, every position in space is the same. Gravity is not.

Inertial Force and Gravity are Different Things (rewritten)
◎ Inertia Force
1) Between inertial force and motion of a mass point in space, there will be direct connection.
2) Position in space has no meaning. Space is homogeneous isotropic.
3) Absolute space is required.
◎ Gravity
1) Between gravity and motion of a mass point in space, there will be no direct connection.
2) Position in space has meaning. As a gravitational field. Space is not homogeneous isotropic.
3) Absolute space is not required.

Inertial Force and Gravity are Different Things (additional)
It is argued that inertial force and gravity are equivalent. However, in light of the followings, the two will not be equivalent. Even if vectors as action cancel each other out, vectors as existence do not disappear. Qualitatively, quantitatively. These are composition and decomposition of forces.
◎ Inertial force corresponds to accelerated motion of a mass point in homogeneous isotropic space.
◎ Gravity corresponds to position of a mass potint in space modified by gravitational fields.

"Gavitational Acceleration"
If magnitude of vector of gravity and another force (e.g. tension) is the same, body will show the same vector of acceleration. On idiom (compound word) "gravitational acceleration", sense of incongruity cannot be wiped out.
Idiom "gravitational acceleration" seems to be meaningful only in limited situationon. Free fall, gravity at the surface of Earth, etc. Is it an idiom of physics ?
If gravity and inertial force are different things, gravity and acceleration are also different things. Will there be qualification of idiom ?

Inertial Force is not Fictitious
Gravity acts on a body as a vector. At a local area in free falling elevator, vector of gravity and vector of inertial force (vector of action, not of existence) will cancel each other. In that case, inertial force will not be fictitious.

Centrifugal Force is not Fictitious
The same four spheres, connected to the ends of two rods are rotating on a plane (no friction). Asuume the bar as a cross and the whole as a disk. At any point on the rod, magnitudes of the centrifugal force and centripetal force are equal, as shown by Newton's third law of motion. That is, centrifugal force (and centripetal also) is not fictitious to an observer in any frame.

Inertial Resistance/Inertial Force
A mass point is placed in aether frame, but when it is forced to move other than uniform linear motion (including zero speed) relative to aether frame, it shows resistance called inertial resistance. Inertial resistance is commonly said to be inertial force. Inertial force will correspond to motion of the mass in aether frame, qualitatively, quantitatively.

Centrifugal Force is not Fictitious
Allow me to alter some of previous post. Previous setting was four spheres and two rods. Now,on two spheres and one rod (in X direction only), mass is two times (without deflection). Then,at close to the center, magnitude of centrifugal force and centripetal force will be about two times. Also, magnitude of centrifugal force and centripetal force will correspond to rotational speed.

About centrifugal force, allow me to post onece more. A disk and the same ten spheres (evenly spaced around the disk) are rotating on a plane (no friction). Spheres and outer edge of the disk are connected with strings of the same length. Each string will show the same tension. Tension will be a sign that centrifugal force is not fictitious.
Note) Centrifugal force and centripetal force will work on the string (on every point) as Newton's third law of motion.

Speed of Gravity Propagation
Speed of gravity propagation is said to be the same to speed of light. But is it true ? Something can't be found in thought experiments ? How about Sun and Mercury ? Solar system is said to move in the direction called sun facing point (on the celestial sphere). So position from which gravitational force of Sun acting Mercury will be the position some back in time. If so, this effect will slightly acuumlate (like free falling).
In Encyclopaedia Britannica 1969, there is a passage as follows (in item "Gravitation" ; original text). "If the action of gravitation were not absolutely instantaneous"(omission)"All experiments and observations were, however, consistent with the law, from the short distances employed in laboratory experiments to the long ranges used in interplanetary calculations". It says, action will be instantaneous.

Perihelion Shift of Mercury (rewrittn)
In a figure, Mercury is drown as a circle. Plus, the figure shows the center of the circle and an arc extending upward and downward through the center (that is a part of orbit). Tne arc divides Mercury into left and right, and the area is left > right. This figure will show that actual magnitude of centrifugal force exceeds that calculated for Mercury as a point (see formula of centrifugal force). Perihelion shift of Mercury may be due to Mercury's size.

Decelerated Motion
Constant tension is acting on a rope extending from a passenger car to the left, and passenger car is decelerating. Even if the ground speed of passenger car becomes zero due to deceleration, tension of the rope is constant. So passenger car starts accelerating to the left. But, there will be no difference in situation in before and after of passenger car. And, there will be no point significant in the ground speed of passenger car.

Peliherion Shift of Mercury
Moon is said to be moving away from Earth by several centimeters per year. I proposed formally (in 68), size of orbiting celestial body increases its centrifugal force (compared to calculated as a point). And so, it moves forward the long axis of elliptical orbit, and also it increases the length of long axis a little ? Is Mercury moving away from Sun too ?

Perihelion Shift of Mercury
Size of Mercury will increase gravity and increase centrifugal force quolitatively also. Of the two, gravity is probably the main factor. Because, increase in gravity shift aphelion in the direction of revolution. On the other hand, increase in centrifugal force shift aphelion in the opposite direction of revolution.
The formula for gravity, F = mM/r^2, probably shows that magnitude of gravity is related to the size of Mercury (but surprisingly small).

There is one more problem. Size of Mercury receives surplus force. But where does this surplus force go ?
In figure of perihelion shift of Mercury,its destination seems not to be found. Ah, perhaps the same phenomenon as Moon's retreat (Moon's orbit is expanding) will be destination. This surplus force probably turns and expands Mercury's elliptical orbit each time.

Perihelion Shift of Mercury (rewritten, from my post, posted on Sep 16 or around)
There is a figure of Mercury and its orbit. Mercury is drawn as a single point. But actually, Mercury has a size, and this size will slightly increase magnitude of gravity and centrifugal force of Mercury. Now, limit our consideration to half of orbit from perihelion to aphelion. Increase in gravity will shift aphelion in the direction of revolution. On the other hand, increase in centrifugal force will shift aphelion in the opposite direction of revolution. In increase, gravity will exceed.

Size of Mercury will cause the difference in its gravity and in its orbit. It will rotate long axis and shift perihelion (in the direction of revolution).
But, will size of Mercury cause difference in its centrifugal force ? This difference probably correspond to the difference in motion that is caused by difference in gravity.

Size of Mercury will increase Mercury's gravity. The main result will be slight expansion of orbit, and followed by shift in perihelion. Therefore, centrifugal force also increases. Newton's third law of motion will be inviolable.
