David said that most important is to put the right questions. So, I try one question:

How is it possible that scientists can accept dark matter and dark energy and still deny the dark ether?

Many prolific scientist have supported the idea of a medium or ether including James Clerk Maxwell and Einstein (& Einstein was after the Michelson–Morley experiment). I like the idea that the ‘ether wind’ is hiding in plain sight as gravity. This idea was first discussed between Newton and Boyle as described in this video:
