Distance between Moon and Earth is measured with millimeter precision. Measurement is based on the formula "distance = speed of light x round trip time / 2". What is noteworthy here is that the direction of laser beam with respect to celestial sphere does not affect the measurement results.
Assume that the space where Moon and Earth exist is also filled with aether. Measurement results will differ depending on the direction of laser beam with respect to celestial sphere (according to the explanation of MM experiment).
However, aether does not affect the propagation of electromagnetic waves at the distance between Moon and Earth. That is, aether does not affect the propagation of electromagnetic waves for a few seconds after emitted. Ritz's emission theory is revived, although in a limited extent. For now, let's take this as an assumption. There is no need to be worried about the framework of time or space.
