This work presents, for the first time in history, a coherent and correct concept for stellar aberration based on the wave nature of light and classical physics. Considering the spherical propagation of the light wavefront and the motion of the observer relative to the Cosmic Microwave Background (CMB) leads to a physically meaningful formula that, unlike the classical formulas, relates to the squares of the velocities for light and the CMB. Moreover, stellar aberration is explained by the entire light path from the star to the observer, with significant consequences for the concept of a dragged ether and the reinterpretation of a large number of experiments. It is demonstrated that all relevant experiments can be consistently explained within the framework of an ether fully dragged by gravity. The anisotropy of light is presented from a new perspective, and time dilation and length contraction become obsolete.
