If two ships flow through space at near light speed next to each other
light will be left behind as it has to travel accross space to the
next ship. Each will see the other ship slightly behind because light
gets left behind in space.

We need to distinguish between momentum, and acceleration and gravity.
A body moving with constant momentum with respect to the aether has
the aether pressure applied equally to each and every nuclei which is
the matter which is the body.

When a body is accelerating or the body is under the influence of
gravity the pressure associated with the aether is not applied equally
to each and every part of the nuclei which is the matter which is the
body.

The reason all objects fall at 32ft/sec^2 in a vacuum near the surface
of the Earth is the pressure associated with the aether displaced by
the Earth is greater 'on top' of each and every nuclei which is the
matter which is the body pushing the body towards the Earth. As the
body is being pushed by the aether pressure towards the Earth more
aether is continually 'on top' of the body pushing the body towards
the Earth and so on. This is why objects accelerate as the 'fall'
towards the Earth.

The aether is not at rest when displaced. We know this because light
reaches us from where Jupiter was in its orbit (i.e. Jupiter does not
leave a void in its wake). Aether pressure abides by the inverse
square law.

I stay away from describing the aether as 'speeding up'. I prefer to
discuss the state of the aether as its state of displacement and its
state of at rest with respect to the matter which displaces the
aether.

Light travels at 'c' with respect to the aether. It might be more
informative to discuss the light from lightning strikes on the train
at A' and B' and on the embankment at A and B. Let's assume the train
is full of flat bed cars and the lightning strikes occur above the
flat bed cars on the train at A' and B'. Let's also assume the
lightning strike occur above A and B on the embankment.

"the state of the [ether] is at every place determined by connections
with the matter and the state of the ether in neighbouring places"-
Albert Einstein

This means the aether is more at rest with respect to the embankment
than the aether is at rest with respect to the train. The light
travels from A and B to M and the light travels from A and B to where
M' is when the light reaches M'. The light travels from where A' and
B' were with respect to the Earth at the time of the lighting strikes
to M'. Measuring to A' and B' on the train in order to determine how
far the light travels to M' does not accurately reflect how far the
light traveled in nature from the lightning strikes at A' and B' to
M'. A' and B' have moved with respect to the aether between the time
of the lightning strikes and the time the light reaches M'.

This means the aether is more at rest with respect to the embankment

travels from A and B to M and the light travels from A and B to where
M' is when the light reaches M'. The light travels from where A' and

Light flows through space pushed by time. Space has its own aether
that is the main "push" to matter behind all of physics. The strength
of gravity does not require this aether to push. Since space flow push
is what God is doing in physics. The rest of the pushes are from
space's aether.
