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: http://ajp.aapt.org/resource/1/ajpias/v76/i6/p519_s1? [Broken] http://arxiv.org/abs/gr-qc/0411060 "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!
