Abstract:
In the latest issue of the "Bulletin of the Astronomical Institutes of the Netherlandes (2)" Prof. De Sitter takes care of my astronomical tests (3) in favor of the applicability to light, of the speed composition rule of classical mechanics and of the general explanation of the phenomenon of the "variability of the stars" which I deduced.
While acknowledging the accuracy and novelty of my deductions, he believes that they bring no argument in favor, but that they add one again against the ballistics hypothesis.
He observes, that if the variability of the stars were due to the effect predicted by me - i.e., dependent changes in light intensity by the periodic motion of the source - should be accompanied by displacements of the spectral lines (due to the Doppler effect). enormously larger of those measured up to now, because photometric effect (as I will call that one predicted by me) and the Doppler effect would depend similarly on one same size.
