Aether, Again !!

[nakayama]

How about diurnal aberration of the moon at the pole of the earth ? If it’s 0, emission theory (in moon-earth scale) seems to be true.

And why on the moon, annual aberration is not subject ?

A web-site says “planetary aberration is combination of aberration and light-time correction”. Yes, light-time correction must be grasped as angle. Time is not main subject at all, i believe (so, naming is wrong).

[nakayama]

Why annual aberration caused by earth’s motion (30 km/sec) doesn’t occur on the moon ? In moon-earth scale, emission theory will be valid. And many facts (such as corner cube set on the moon’s surface) will support it.

[nakayama]

Value of light-time correction for the moon is 0.704 arcsec (corresponds to moon’s speed on orbit). And annual aberration (20.496 arcsec ; max) is not observable for the moon. These are different fundamentally from observational facts for all celestial bodies (except for artificial bodies ; earth’s motion 30 km/sec is not reflected).

Reason will be nothing but nearby distance (imagine an instant). The emission theory will be true (in moon-earth scale).

[nakayama]

In moon-earth scale, emission theory seems to be valid. If so, understanding as follows will be possible (if there is no mistake).

Imagine that two horizontal lines and a vertical line cross. The moon is situated at the upper intersection and the earth is at the lower. Point of this thought experiment is an instant when the moon moves horizontally. Now, value of light-time correction for the moon is 0.704 arcsec (corresponds to moon’s speed on orbit). But is it true ? It will be possible to say that the earth is moving (because there is no rest frame). If so, this value will be possible to be regard as value of aberration (on the earth).

In moon-earth scale, real aberration and real light-time correction will not exist (because aether doesn’t act at all).

[nakayama]

In the above figure, replace the moon and the earth with two space ships.

Distance between the moon and the earth is measured to meter level (with light beam). This will mean that emission theory is valid in moon earth scale (if aether acts, difference km level will be measured).

-Annual aberration for the moon ; An Apology- i forgot my view that i posted before.

A light source and an observer move in a uniform motion at the same speed (along parallel lines ; imagine an instant only). The observer doesn’t observe aberration, because aberration is offset fully by light-time correction (each is composed of v and c). About secular aberration for the sun (seen from the earth), it will be the same. But about the moon, thing is different if emission theory is valid (in moon-earth scale). Anyway, annual aberration for the moon is not observable.

[nakayama]

Imagine a figure that is shown in the above post (Nov 17). Along the lower line, two space ships are moving at different speed. One observes value 0.704 arcsec and the other 1.408 arcsec. What is this value ? This value will be recognized as not light-time correction (like) but aberration (like).
