The main issue with the 'Mainstream Scientific Establishment' is not
understanding aether has mass. What is presently postulated as non-
baryonic dark matter is aether. Aether physically occupies three
dimensional space and is physically displaced by matter.

A moving particle has an associated aether displacement wave.

Force exerted toward matter by aether displaced by matter is gravity.

Understanding aether has mass unifies GR and QM.

Aether displacement is the theory of everything.
