lol!
Oh, you're serious?
This thread is titled 'Aether Displacement'.
What is presently postulated as non-baryonic dark matter is aether. Aether has mass. Aether physically occupies three dimensional space unoccupied by matter. Aether is physically displaced by matter.
Force exerted toward matter by aether displaced by matter is gravity.
A moving particle has an associated aether displacement wave. In a double slit experiment the particle enters and exits a single slit. It is the associated aether displacement wave which enters and exits both. The associated aether displacement wave creates wave interference upon exiting the slits. As the particle exits a single slit the direction it travels is altered by the wave interference. Detecting the particle causes there to be a loss of coherence of the associated aether, there is no wave interference, and the direction the particle travels is altered.
Curved spacetime physically exists in nature as displaced aether.
