On the moon's surface, there is a passenger car. To the roof of the passenger car, waves of the sun-light are coming horizontally. On the roof of the passenger car, there is a hole. When the passenger car moves to the right (or the left), whether projection of the hole (on the floor) moves or not ?

There is a wind tunnel made of glass. It's set horizontally (Air is moving horizontally). Plane waves of light are coming from just above. These waves may transmit the roof of the wind tunnel horizontally and may reach the floor of the wind tunnel horizontally also. But how about the light ray ? Light ray may not be 90 degrees (with light waves) to an observer who is at a standstill relative to the wind tunnel. From this angle (not 90 degrees), the speed of the air may be determined. In the aether (outer space), it may be the same.

Attention

[About the post dated on 7 Sep]
In a forum, there is a reply as follows. The speed of passenger car is too small. But if it (The spot-light on the floor moves qualitatively. Because of aberration) is actual, moon's motion may has an effect (on the spot-light) also. The angle of light ray (in the passenger car) may not be 90 degrees.

Moreover, the motion of the solar system may has an effect also. On the other hand, in the air, light ray is 90 degrees with light waves always. Because, reference frame (air) is at a standstill relative to observer.

To make a flat plate level (horizontal) with plane waves may be possible theoretically.

Sorry, i made mistake. Allow me to withdraw this post. In this situation, the angle of light ray (with light waves) is 90 degrees (According to the emission theory).

A prism is pointed at a star just above. When this prism moves to the right (or the left) in the aether (in the outer space), what phenomenon does occur in the prism ? Frequency of the incident lights (enter both faces of the prism) is the same. However, light speed (relative to the faces) is not the same. Therefore, wave length of the incident lights (in the prism) may not be the same.

Very sorry. Now, i feel that conclusion of above post (9 Dec) is not certain. Please allow me to compensate with following.

On the moon's surface, there is a pillar made of glass that lies horizontally. From the upper right and the upper left, plane waves of star light are coming. Wave length/wave number (it's invariant) of two waves is supposed to be the same. Now this pillar moves to the right or the left. Frequency and light speed of the incident light (seen from view point of the inertial frame of the pillar : Before incidence) may change. And in the glass, frequency and wave length/wave number (refraction angle also) may change. These changes show the motion of the glass relative to the aether.

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.

Because of the motion (in the eye direction) of light source, wave length of light is changed (shifted). But if an observer moves in the same motion as light source, how about to the observer ? Frequency became the same to the light source, but wave length may not be changed (by this observer's motion). This may show the motion of the both relative to the medium (when the light source is heavenly body, it's aether).

In the outer space, two mirrors are set at a 45 degree angle (like letter V), and are reflecting star lights down (on the right and on the left, there are two stars).

Above two mirrors move together to the right or the left. By this motion, it's able to equalize the frequency of two reflected lights. And frequency of two incident lights is the same also. Therefore, by the wave length of two incident lights, light speed relative to the aether may be found.

[P.S.] The sum of the speed of above two incident lights may be below 2c.

Light rays (shower) of a star are coming. Along a straight line (crosses light rays), two observers are moving at different uniform speed. Angle of light rays to observers is different (different inertial frame, different phenomenon).

[Momentum and Rest Frame]

Momentum of a point mass is changed by motion (excepting uniform linear motion) of this point mass. It will show the existence of rest frame.

[Newton’s Bucket and Rest Frame]

Two disks are rotating (in outer space ; in non-gravitational field ; horizontally). Rotating speed of one disk is 10 rotations per second and that of the other disk is 20. A body is detached from the edge of disk and is receding along a tangent line (and every tangent line does not rotate relative to space). It will be the same about a photon (emitted from a rotating source).

Why is a pulsar visible as a point (not short line)? It will be caused by aether.

On the moon's surface, there is a passenger car. To the roof, waves of sun-light (plane waves) are coming horizontally. In the roof, there is a small hole. When the passenger car moves to the right (or the left), whether projection (spot-light on the floor) moves or not ?

Moon's motion will have an effect (on the spot-light) also. The angle of light ray (in the passenger car) will not be 90 degrees.

On a space ship, the above is measured about a star light (at the same time, measurement is done about star light that comes from the opposite direction). By this way, motion of the space ship relative to aether will be clarified.

In a web-site (in Japanese), i found value 13.4 seconds of arc (it's value of secular aberration). Surprising !! Above is shown in a report carried in a journal "Report of the national astronomical observatory of Japan ; Feb 1993".

This will mean that velocity of aether&#65288;relative to the solar system&#65289;is about 20km/sec.

-Pending questions-

How does light ray propagate (in vaccum) that is emitted in the side direction from moving source ?One scenario is that it follows aether frame (different from path of body). When speed of the source (relative to aether) is supposed to be 30km/sec, difference (between emission theory) of light speed (per second) will be meter level. It will be difficult to distinguish.

A web-site says that light-time correction occurs on the moon also.

- Apology & Withdrawal -

Above post (Sep 30) was wrong (sorry, i forgot MM experiment done in vacuum entirely). Even in aether, in every direction, light will propagate at the same speed.

Emission theory is true and it’s valid within limited extent only, i believe. Perhaps, this extent differs in the front and the rear (and in the side direction) of moving source.

&#65309;Reconsideration on previous posts (Oct 4 & Sep 30)=

If light-time correction of the moon is true (and if light speed is constant in moon-earth direction), a question arises.

How is emission theory valid in moon-earth scale ? Propagation of light wave will deviate from a concentric circle (true sphere) slightly.

Does light-time correction occur in earthly scale (in vacuum)? Common precision of MM experiment seems not to solve the question (precondition of propagation in aether flow direction differs).
-Note- The value of secular aberration is measured. So, we know aether flow thoroughly.

-Note ; On light-time correction-

This phenomenon is caused by aether. So, common explanation is beside the point (and complicated). The web-site that i saw seems to grasp it as a sort of parallax (i do so also). If the emission theory is valid perfectly, this parallax doesn’t occur.

-Light-Time Correction for the Moon-

If laser beam is returned always by corner cube set on the moon’s surface, the emission theory seems to be true. And light-time correction will not occur. Or in moon- earth scale, two theories (emission theory & theory that propagation of light follows aether frame) are valid partly ?

Information is lacking and common view (on light-time correction) is beside the point.
