Aether Wave Theory brings the best understanding of Aether concept so far and from it follows, negative result of Michelson-Morley experiment is a direct consequence of Aether model, instead. Such stance can be expressed in single theorem:

No (motion of) environment can be observed by its own waves.

For example, from perspective of water waves water surface would always appear like empty void space without motion JUST BECAUSE it is serving for surface wave spreading like local space-time.
