Hi all
Halc can I please just clarify your points in regards to;

All clocks are affected by these things. Atomic clocks are in no way special in this way. Paint peels slower relative to a frame in which it moves faster.

In regards to your first point does direction of relative away/towards have any bearing

"Direction of relative" does not parse. If you mean direction of motion, the answer is no, it matters not. In SR, time dilation relative to inertial frame F is a function of your speed relative to F, and speed, being a scalar, doesn't have a direction.

The coordinate rate of clocks can indeed be negative given a non-inertial coordinate system.

are you stating rate of atomic clocks as negative as going in reverse or just slowing down ?.
Because if negative = reverse

I meant reverse. We're talking about a coordinate effect, and one can create a non-inertial coordinate system where some clocks run backwards. Look up the Andromeda 'paradox' as an illustration of this.

are we not setting the scenario of the paint analogy going from peeling/flaking into the wind to.  returning to the painted surface becoming shiny and new then liquid in the brush/sprayer to been back in the paint tin ?

If my coordinate system orders the paint events that way, then yes. It's just a coordinate system.

So is it not just an energy wave detector, detecting an effect from a cause ?

It is an energy wave detector. The gravitational waves are a cause by which changes in the mirror distance can be detected. That is a cause producing a detectable effect. We can know when they are caused by gravitational waves and not local disturbances because (1) gravitational waves produce predictable, regular and opposite changes between the two different arms of the detectors, and (2) LIGO has two stations very, very far apart: one in Louisiana and one in Washington state. If both detectors pick up the trademark pattern of a gravitational wave at roughly the same time, then that rules out local vibrations as the cause. VIRGO, a similar gravitational wave detector in Italy, can provide further confirmation of the detection.
