In space, spaceship is floating (not accelerating). From this spacecraft, multiple probes begin a uniform linear motion towards assigned star on celestial sphere. A light source set on the probes that shines at a certain frequency is visible from the spacecraft.
Is the assumption that propagation of light in two ways (written before) correct ? If correct, frequency of probe's light (reaches the spacecraft) that emitted from before and after a few light-seconds distance will be different (although in rare cases it may not be different). The two, emission theory and aether will revovebe as phoenixes.
