Are you saying that by placing the bowling ball in the aether the pressure of the aether is increased and causes a pressure wave to be transmitted through the aether; and that it is that pressure wave transversing the aether that affects the feathers :shrug
The bowling ball and the superfluid are being used as analogies for particles of matter in the aether.
Let's try and stick with one or the other. Let's discuss a bowling ball and a superfluid
or particles of matter and the aether.
I'm going to discuss particles of matter and the aether.
There is a wave out ahead of the solar system. As the solar system moves through the aether the solar system displaces the aether. The wave out ahead of the solar system is an aether displacement wave.
As a galaxy cluster moves through the aether the galaxy cluster displaces the aether. That is the reason why there is an offset between the light lensing through the space neighboring galaxy clusters and the galaxy clusters themselves. The offset is caused by the light lensing through the aether displaced by the galaxy cluster.
When galaxy clusters collide the ripple they create is an aether displacement wave. What is mistaken to be a dark matter core being left behind after the collision is the aether 'sloshing' back.
A gravitational wave is an aether displacement wave.
A moving particle has an associated aether displacement wave. In a double slit experiment the particle travels through a single slit and the associated wave in the aether passes through both.
What ripples when galaxy clusters collide is what waves in a double slit experiment, the aether.
Einstein's gravitational wave is de Broglie's pilot-wave.
They are both waves in the aether.
They are both aether displacement waves.
