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".
In outer space, frequency and wavelength of incoming lights from two stars (from opposite directions on the celestial sphere) are measured. To the measurer, speed of two incoming lights will be different. And it will mean the motion (in the direction of light path) of the measurer with respect to aether.
Note) If the measurer moves in the direction of light path, frequency and speed of two incoming lights will vary. Because, wavelength of two incoming light does not vary.
Rods of length 4r and 2r are rotating horizontally in the shape of a cross. Assume that four tip of the rod each has mass point of mass m, and the mass of the rod is zero. Tension (centrifugal force) acting on the rod is a true force.
The formula for centrifugal force is F = m v^2/r. And as Newton's third law of motion shows, centrifugal force is an action and centripetal force is a reaction. The magnitude of the force is the same. The two are true forces.
Tension is centrifugal force, an effect of Newton's third law of motion, and centripetal force is a reaction. The two are true forces. Rotational motion can be boiled down to accelerated motion and non-accelerated motion (including absolute rest). Frame will be the celestial sphere and the aether.
Accelerated motion and inertial force correspond qualitatively (also, in the direction of celestial sphere and of aether) quantitatively. This will lead to zero inertial force in non-accelerated motion. Without exception. In addition, let us assume that non-accelerating motion includes absolute rest.
In outer space, frequency and wavelength of incoming lights from two stars (from opposite directions on the celestial sphere) are measured. To the measurer, speed of two incoming lights will be different. And sum of speed of two lights will be 2c (or close to 2c : constant). In post 55, it is forgotten to note. Sorry.
Accelerated Motion and Non-Accelerated Motion (again) (クリ)
Difference between the two motions above will be the difference of motion with respect to aether frame. A mass point moving in accelerated motion is accompanied by inertial force, that corresponds qualitatively and quantitatively. A mass point moving in non-accelerated motion (uniform linear motion) is not accompanied by inertial force.
A saying are trying about inertial force and gravity. What can we say by comparing the two words ? Inertial force is inertial force, gravity is gravity and both are true forces ! That seems to be all that can be said. This is a short report.
On the ground, a passenger car is moving with uniform acceleration to the right. In the car, a body hanging from the ceiling with a string is swinging to the left. The angle can be explained qualitatively and quantitatively using equations based on Newton's laws of motion. What about equivalence principle ? Is there anyone who can ?
Allow me to repeat the previous question,regarding two situations ◎ below. Two situations ◎ can be explainend qualitatively and quantitatively using formulas based on Newton’s laws of motion. The question is, can equivalence principle explain these also ? Is there anyone who can ? .
◎ Forces of the same magnitude are acting on a mass point from the left and right directions. Types of forces are tension, gravity, and inertial force. Since there are no combinations of inertial forces and inertial forces, there are five combinations of forces (ignoring the difference between left and right).
◎ A body is sliding down inclined surface (no friction).
Formula for the law of universal gravitation is F=GMm/r^2. Value r is the distance between centers of gravity of the two bodies (let's call them spheres L and R). If r is 50, the squared is 2500. It is the first diagram.
Now, this is the second diagram. On horizontal straight line, spheres L, R1, and R2 are lined up. If distance between L and R1 is 49, and distance between L and R2 is 51, the squared are 2401 and 2601. If these two are added and divided by 2, value 2501 is gotten, which is slightly larger than 2500. In other words, the formula of universal gravitation doesn't care about the size of the two sources of gravity, but in reality, there will be a difference, even if it's a little ? Is Newton's spherical shell theorem not perfect ? Is this the main cause of apsidal precession ?
Note) 2500 and 2501 are coefficients in numerator of the formula.
Note) Masses of R1 and R2 are each 1/2 of the mass of R in the second diagram.
Note: Assume that R1 and R2 are hemispheres of R (distance of center of gravity is 2).
