Hi mpc755, and welcome.

But your ideas about aether, is now thought of in terms of the Higgs Field, if you want to search that or Higgs Boson. Some of your thoughts may still apply, as the general charactorists are the same, but the mechanism more clearly defined. May be Marshall will comment.
You can label it aether, ether, Higg's field, quitessence, quantum foam or quantum vacuum. It doesn't matter. What all the labels are discussing are the physical properties associated with three dimensional space unoccupied by particles of matter.
What I have figured out is aether has mass. There is no such thing as non-baryonic dark matter traveling with matter. Matter moves through and displaces the aether.
Aether and matter are different states of the same material.
Particles of matter are condensations of aether.
What I have also figured out is what occurs physically in nature to cause gravity.
Particles of matter displace the aether.
When you get to something as large as the Earth, the aether displaced by the particles of matter the Earth consist of which pushes back and exerts inward pressure toward the Earth is gravity.
I have also figured out what occurs physically in nature to cause the observed behaviors in a double slit experiment.
A moving particle has an associated aether displacement wave. In a double slit experiment the particle travels a well defined path which takes it through one slit while the associated aether wave passes through both.
Aether displacement unifies relativity with quantum physics.
What ripples when galaxy clusters collide is what waves in a double slit experiment; the aether.
The ripple is a gravitational wave.
Einstein's gravitational wave is de Broglie's pilot-wave.
They are both aether displacement waves.
