So this aetheric wind, how was it 'discovered'?
Or can I do something similar?
I believe the earth is round due to the aetheric pressure that pushes equally in all directions affecting mass and determining that the most perfect and elegant shape that it can form is a sphere.
Is the 'evidence' behind aetheric wind really any different than this?
Aether is a theoretical substance, just as dark matter is, just as are gravitons. None of these have ever been directly measured, but their existence is postulated because their respective scientific models have a need for them.
I freely admit that I am in the realm of pure hypothesis in this thread, in the interest of productive thought, but some people don't seem to be able to stop beating their own "whar is teh evidence" drums long enough to enjoy a little free discourse.
Another poor analogy. Dark matter was postulated because there is observed evidence that is difficult to explain without either modification of the theory of gravity, or the existence of more matter than we can detect by current conventional means - and there is NO explanation for the observations in currently proven physics. Hence the need for new hypotheses. Aether, by contrast, is not needed, as the observable environment of the earth and its visible celestial sky rotation, CAN be explained by currently proven physics - using the round earth model. You might not agree with it, you might not think it's true, but you
cannot truthfully say the round earth model does not provide an explanation for what we observe around us. Because it does. If conventional physics could provide a hypothesis that would explain the anomalous rotation of galaxies, then nobody would have thought up dark matter in the first place. We demand independent evidence for aether because it is not the only explanation that works.
As for gravitons, these are theorised to exist simply because as we study the universe at a closer and closer level, it appears that almost all forces are controlled by representative particles. The graviton is a suggested particle that could operate in this way for gravity, but no serious scientists claim it exists without doubt, and it's not actually necessary to know if it's there or not to study the majority of the properties of gravity - any more than knowing that photons exist is essential for understanding the basic workings of light.
