A light path is coming from a star. The frequency of this light is changeable by the motion of observer (It's Doppler effect). This change of frequency means the change of the light speed (because, wave length (wave number) of this light path is unchangeable). Note : Light speed = frequency x wavelength.
Two light paths are coming from a star. When two observers move along each light path at different speed, wave length of the two light paths (lead to the star) differ (If Einstein's theory is right). Note : Light speed = frequency x wavelength
It's improved version. Any refutation may be impossible.
Three light paths (A, B and C) are coming from a star and reach three observers (A, B and C). Observer A is at a stand-still. Observer B and C are moving (one moves toward the star, another moves toward opposite direction). From view point of observer A, wave length of the light path B and C must be different (if Einstein's theory is right).
[Relative to light source] : constant c, in vacuum only, may continue for a few second (it's emission theory).
[Relative to aether] : constant, slower somewhat than c.
[Relative to medium] : constant c/n, equalized by extinction.
[Relative to observer] : variable (As formula : light speed = frequency x wavelength shows).
A mirror is reflecting a light ray. When the mirror moves relative to light source, varying (change of wavelength caused by mirror's motion) moves at the speed of c or c/n on the reflected light path. But how about on the incident light path ? None can explain, i think (Only frequency and light speed of incident light are changeable).
Common view says that Doppler effect of sound and light are different. But except for one situation, both may be the same (in the air, quite the same). Because, sound and light both propagate through medium at constant speed (in the vacuum, light propagate through the aether). Only in the vacuum, and moreover immediately after the emission from light source (may be a few second), Doppler effect of light may be unique.
There are two lines spectrum (peculiar to atom or molecule) in a star light. By measurement of the distance between the both, the motion of this star (that of eyes direction) relative to the aether may be detectable. Therefore by measurement of the frequency of the line spectrum, the motion of the earth relative to the aether may be detectable also.
They cry and cry, GPS,GPS. But how about that satellite : the moon ? Is time dilation measured actually ? Where is the starting point of reckoning ? From view point of an observer on the moon's surface, is there any difference between time dilation of Singapore (near the equator) and the North Pole (From view point of an observer on the earth, there is no difference) ??
And to two observer (at the above two points on the earth), how about the watch on the moon ? Even as an armchair theory, it seems not to stand up.
In the vaccum, there is a light source (on the left) and hollow tube (on the right). Light ray is passing through this tube (from the left to the right). Light source is at a stand-still and tube moves to the right at a speed of 150,000 km/sec (and tube's length is 150,000 km !!).
According to Galilean transformation, light speed relative to the tube is 150,000 km/sec. How does Lorentz transformation explain ?
On the moon's surface, there is a passenger car. It's roof is made of glass. From just above, light waves (plane waves) of a star are entering this roof horizontally. These plane waves reach floor horizontally also (it must be so geometrically). If Einstein's "right triangle" is right, when the passenger car moves, number of waves that stay between the roof and floor may increase. And it may be the same to an observer who is in the passenger car (it's irrational. speed of light ray in the moving car is appearance).
[P.S.] The speed of wave front (horizontal) in above passenger car (moving) may be visible to be the same to an observer who stands on the moon's surface.
In the outer space, a mirror is reflecting a light ray. The angle of incident light and reflected light may not be the same generally. Because speed of incident light is variable.
