The reason why I am discussing non-baryonic dark matter is to show there is zero evidence it is gravitationally bound to matter.
Once you understand matter moves through non-baryonic dark matter you should be able to correctly understand what is postulated as non-baryonic dark matter is aether.

"The original Michelson–Morley experiment was useful for testing the Lorentz–FitzGerald contraction hypothesis only."
The Michelson-Morley experiment was looking for the 'aether wind'.
This has nothing to do with the aether of relativity.
The state of the aether of relativity at every place determined by its connections with the Earth and the state of the aether in neighboring places is the state of displacement of the aether.
Watch the following video starting at 0:45 to see the state of the aether at every place determined by its connections with the Earth and the state of the aether in neighboring places which is the state of displacement of the aether.
