## The apparent change of angle in a force-free ether

When you are interested in physics you must read “Unbelievable“!

The reader may wonder how an apparent change in angle and impulse of a photon, the stellar aberration, is possible when there is free-force ether (vacuum). The stellar aberration is observed from the earth, but actually there is no real change of the path during the passage of the photon from the star y-Draconis to Earth. The photon only appears to come from a different direction. The on Earth observed stellar aberration is not for real.

To comprehend this the reader must be aware of the relative movement of both ethers in figure 2.

In figure 5 we consider the photon from the star y-Draconis arriving and observed on the earth. The stellar aberration takes place at the surface where the two ethers have a relative speed to each other.

Figure 5.  The imaginary change of direction/impulse of the photon from y-Draconis.

At t=0 the photon from y-Draconis is entering the ether under influence of the earth at point A. The Earth is then at the position Earth A. The moment the photon enters ether II the change of angle β, the stellar aberration, and Doppler-effect occurs. The photon is now traveling with the speed c in ether II. After the penetration of the photon in ether II it takes the photon t seconds to arrive on the surface of the earth to be observed. During the seconds the Earth moves 30km/sec.t meter to the right (Earth B), just like ether II, which is under influence of the earth. So ether II also moves during t seconds to the right.

When the photon reaches the observer on Earth, one observes the stellar aberration ß, but yet the photon has kept the original direction it had, when it was emitted from the star y-Draconis. The photon for the observer on Earth seems to come from B, but that is only appearance.

The direction of the photon in ether II has changed (ß) compared to the direction in ether I, but because ether II moves relatively to ether I, the original direction of the photon is maintained. The stellar aberration in ether II compensates exactly for the relative movement of ether II compared to ether I. The photon keeps the same direction and impulse before or after penetrating ether II for any observer in rest with the Earth or y-Draconis.

It is of no influence at what distance from the Earth the stellar aberration occurs. The observed stellar aberration ß does not imply a real change in direction of the photon. Although it appears that the photon has changed direction, and therefore the impulse seems to be altered, this is actually not the case. The assumed force-free ether (vacuum) does not change the impulse or direction of photons.

The stellar aberration predicted by the theoretical formulas derived in this chapter matches the actual, empirically measured, aberration of any star at any time during the year. The empirical aberration evidence supporting the dragged ether theory is overwhelming. The same cannot be said for the poor explanation of stellar aberration given by SRT.

The explanation given by SRT for stellar aberration is very paled. Actually the only “explanation” SRT gives is the Lorentz-factor. The stellar aberration of a star that stands vertical on the periphery of the Earth around the Sun can correctly be calculated with the mysterious explanations of SRT. For all other stars the explanation of SRT is inadequate. It is hard to believe that only the assumption of an absolute empty space and the derivation of the Lorentz-factor with SRT is enough  to accept a speculative theory like SRT! The explanation of stellar aberration given by ether theory is much better, and should be preferred by Science.

The measured stellar aberration is for any star with the same inclination (θ) exactly the same (except for the phase shift caused by the position of the earth in the orbit around the sun).
