Michelson-Morley experiment (done in air) is nonsense (クリ)
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".
The defined value of speed of light is based on measurements (with wavelength and frequency) done by Evenson et al. in 1973. Error is 1.1 m / s in pramai. Now measuring instrument is separated into a measuring part and a light source part. When one of them is moved at a constant speed higher than above error (in the direction of light path), different value will be obtained.
Light is propagated in two ways (as follows).
1. In outer space, a star light is reflected by a mirror. Speed of incident light is constant relative to aether.
2. In outer space, a star light is reflected by a mirror. Speed of reflected light is constant relative to the mirror (the emission theory).
In two pictures sbove each, speed of light to a moving observer follows Galilean transformation.
Plane waves of starlight (wavelength is constant) is arriving from upper left 45 degrees. Two spacecrafts are sailing in the right and left directions. Number of waves hitting the front and rear ends (A and B) of each spacecraft is the same. Therefore, number of waves existing between A and B is invariant (for both spacecrafts, regardless of lateral motion). Lorentz contractions will be impossible.
Relativity of simultaneity will be impossible also.
All kinds of aberration are caused by motion of Earth. Qualitatively, quantitatively. For example, cycle of annual aberration is 365 days. It is reflection of motion of Earth. On the other hand, any motion of star’s side has no influence. Only position on the celestial sphere is valid. These facts will be explainable only by aether.
For an observer stationary with respect to the aether frame, there will be no aberration.
Aberration is caused by various motions of Earth relative to stationary aether (uniform isotropic). Light that enters upper air of Earth (from aether) is bent in the direction of motion of Earth. As a phenomenon, aberration is completed in the upper air. The same as refraction.
Therefore, illustration of raindrops and an umbrella is NG. Result of Airy’s experiment with a water-filled telescope is only natural. It is said that apparent displacement of stars is displaced in the direction of Earth’s motion, but in fact, it will be the opposite. You can check this by drawing light bending (in upper air) on a paper.
For gravity and inertial force in free-falling elevator, acceptable explanation will be Newton’s law of action and reaction. Equivalence principle should be forgotten.
The same five bodies (mass m) are lined up sideways on a horizontal plane. Five bodies are tied with four strings. Assume that horizontal plane is zero friction, and mass of strings is zero. On right most body, force of 5ma is acting to the right and five bodies start a uniform linear accelerating motion toward the right. Tension acting on four strings are, from right to left, 4ma, 3ma, 2ma, and 1ma.
Tension in the string above will be the same to an observer of any frame of motion. Inertial force (accelerated motion) is not fictitious.

◎ Light Clock
A light clock is working in a moving passenger car. In books or in other illustrations, light travels back and forth vertically, but this light clock slightly leans to the right or left. So, the zigzag (sawtooth) of light path seen by an observer on the ground warps. Two kinds of dilations ? And how about if two light clocks with different lean work ?
◎ Time Dilation
In outer space, a spaceship is sailing horizontally. Plane wave of light (wavelength is constant) of the first-magnitude star Sirius is coming from directly above. Phenomenon of time dilation can not be valid.
◎ Relativity of Simultaneity
On the Moon's surface, a passenger car is moving to the right. From the center of the ceiling of the car, light rays are emitted to directly below and diagonally downward to left and right at 45 degrees. And three points of light are reflected on the floor. Three points are symmetrical to observer on the Moon's surface also. Relativity of simultaneity will be invalid.
◎ Perihelion Shift of Mercury
The perihelion shift moves in one direction and its speed seems to be almost constant. Like the hands of a clock. Main cause of the shift seems not to be gravity of other planets. Main cause will be two-body problem of Mercury and Sun. Not as points, but as spheres.
In outer space, a starlight is reflected by a mirror. There is a formula c = f λ. Now, the mirror is stationary. In comparing of incident light and reflected light, f is the same. And usually, c & λ are different.
Now, the mirror moves in the direction of the light path of incident light. In the formula on incident light, λ is constant. And c & f will be variables. And in the formula on reflected light, c is constant. And f & λ will be variables.
◎ Speed of Light
For speed of light, the constant speed, and the formula c = fλ seem to be all. But is it really that simple?
A beam of light is propagating through aether. An observer is in uniform linear motion at various angles relative to this beam. The speed of the observer relative to aether also varies. Observer's motion can be accelerated motion, jerk motion, or curvilinear motion. Also, speed of light wave and light ray (photon) will generally be different.
No, to light, special treatment must not be given. Then, all must be simple.
◎ Aether
In outer space, frequency and wavelength of two stars light are being measured. Two stars are in opposite directions (antipodal point) on the celestial sphere, and the measurements are done simultaneously. The sum of the two values will be 2c or a constant close to 2c.
The above will show the motion of the observer relative to aether.

◎ Accelerated Motion and Aether
Accelerated motion will be absolute motion against aether. Accelerated motion and inertial force are two sides of the same coin. Gravity is not involved and is irrelevant.
That is, we are surrounded by aether.
◎ Acceleration and Non-Acceleration
The passenger car is accelerating uniformly to the right. In this car, a ray of light (frequency is constant) is emitted from the rear to the front. The number of light waves existing inside the car will be higher than when the car is stationary. That is, there will be apparent difference between non-acceleration and acceleration.
Ray of light is emitted from the ceiling of the passenger car downward. If the passenger car is accelerating, the ray draw a parabola. That is, there will be apparent difference between non-acceleration and acceleration.
◎ Local Inertial Frame
An elevator-like but homogeneous rectangular body is in free falling. Suppose this body consists of many local area of mass m. So, inertial force acting on each local area is mg. That is, local inertial frame will be impossible.
Gravity and inertial force are cancelled out partially or sometimes totally. But, it is action that cancelled out, not existence.
There are two figures A and B that draw Sun and Mercury. A shows Mercury on the line of action of gravity of Sun extending from the left. Distance between two stars is 50. In B, Mercury is divided into two hemispheres, left and right. The distance between center of sphere (of A) and the center of gravity of two hemispheres each is 1. In B, denominators of formula for magnitude of gravity are 49 and 51. And squared are 2401 and 2601.
Magnitude of gravity is 2500 in A and 2501 in B. Size of sphere seems to be related to magnitude of gravity. Spherical shell theorem will not be valid. Main reason for perihelion shift of Mercury will be its size.
Note) In this post, only gravity of Sun is under consideration.
◎ Perihelion Shift of Mercury
There is a figure of Mercury. Mercury is drawn as a circle. Plus, the center of it and an arc are drawn. This arc passes through the center and is extending symmetrically upward and downward. This arc is part of circle centered at the center of Sun that is located on the right of this figure. Therefore, the area of Mercury divided by the arc is left > right. Thus, actual magnitude of centrifugal force of Mercury due to its orbital motion will exceed the magnitude calculated as a point. Probably, this will be the main reason for perihelion shift of Mercury.
Note : For planets with satellites, perihelion shif seems to be larger. This will be due to centrifugal force.
Note : There must be more unknowns in perihelion shift.
◎ Doppler Effect of Light
Frequency of incoming light varies with the motion of an observer. In the formula c = fλ, it is clear that the speed of light (for the observer) cannot be constant.
Four the same 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, the 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) is not fictitious to an observer in any frame.
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.
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 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.
In my previous post (14), Mercury is divided into two spheres. But this thought experiment doesn’t seem to explain perihelion shift of Mercury. Because, a/49^2 + a/51^2 = 2a/50^2. Surprising ! And also, it does not disprove Newton’s spherical shell theorem ! So, my hope is shifted in another thought experiment on centrifugal force (2023-03-15).

In a figure, Mercury is shown as a circle. Plus, the center and an arc that through the center and is extending upward and downward (that is a part of orbit) are shown. This 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.

Moon is said to be moving away from Earth by several centimeters per year. As proposed formally, size of Moon will increase its centrifugal force (compared to calculated as a point). This additional amount will be divided in rotation of long axis and in extension of long axis of orbit of Moon. Is Mercury moving away from Sun too ?
[Size of Mercury increases gravity during orbital motion]
Mm/r^2 is formula for gravity. There are models for Mercury and Sun. When, 2Mm is 100 and r is 50, gravity is 0.04. Next, two half spheres of Mercury are lined up on the line of action of Sun's gravity. Mm is 50, r is 49 and 51. Then, gravity is 0.0400479.

Perihelion Shift of Mercury (rewritten, from my post, posted on Sep 16 or around) （クリ)
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.
