**Are "flowing space" models compatible with GR?**

Recently papers have been published with new "flowing space" models for GR. In particular a "flowing river" model by Hamilton:

"In this model, space flows like a river through a flat background, while objects move through the river according to the rules of special relativity. "

I had the impression, years ago, that such models had been disproved because of giving predictions that do not match GR nor experiment; but perhaps this new one is different in a subtle way that escapes me.

In Einstein's GR, space, although of free choice, is taken as stationary reference, relative to which bodies are moving; it's a bit surprising for me if GR is equally compatible with a

**flowing**space model in which a kind of ether flows like a river or waterfall relative to space.

Before starting a test example I'd like to be sure to understand it correctly:

- although Hamilton applies the model to black holes, it should work in general (such as near the Earth) if valid

- he pictures gravitation like an ether flow towards the mass

- an object at rest in the river is entirely unaffected by the flow

Is that correct?

This topic came up in another thread:

That is for me the question![..] Hamilton's river model's are [..] just a conceptual aid. They change not a single equation or rule for computing an observable.
