From the ceiling of passenger car, light ray is emitted down somewhat to the right. One passenger car is moving to the right, another passenger car is moving to the left at the same speed. To an observer who stands on the ground, the length of two lights is not the same.
From the ceiling of a passenger car, light ray is emitted down. When the moving car is filled with water, diagonal of light ray may be more gentle to an observer who stands on the ground. And the diagonal (depends only on c/n and v) may be simple appearance. It may be the same about air or vacuum too (Galilean transformations may stand up about all).
Allow me to repeat to quote, please.Einstein's theory stands up only on vertical light ray (in a passenger car) ? Einstein's theory does not stand up on diagonal light ray (in a passenger car) ?
From the ceiling of a passenger car, a few light rays are emitted to lower right. The angle (of these) is different (one is vertical). How does Einstein's theory explain this (passenger car is moving to the left) ?Sorry, if it's invalid.
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).
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).
Light speed may be various as follows. [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).
i wrote in a forum as follows. 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.
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.
About emitted beam and reflected beam of "Orbis" or "speed gun", the formula : lightspeed = frequency x wavelength is as follows. At observer (at stand-still in the air) : Lightspeed is equal. Frequency & wavelength is not equal. At moving object : Frequency is equal. Lightspeed & wavelength is not equal.In the outer space, lightspeed is not equal at both (observer and moving object).
In a forum (in Japanese), i saw a post as such. 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 ?
In a book "The theory of relativity" by W.Pauli : 1958, there is a passage as follows. "Rather should one say that for an observer moving with the medium, light is propagated as usual with velocity c/n in all directions".It may explain that null result of Michelson-Morley experiment. And may deny Einstein's explanation on the result of Fizeau experiment with flowing water : 1851.
