It is those fields and SM particles that determines the topography.
The point being space itself does not have its own unique particles, which would be required for an ether. Unless you accept the graviton neither does gravity...
Even twistor theory doesn't state space itself has its own particles. Though I had to confirm that with a PH.d that specialized in string/twistor theory.
The metric tensor is determined via SM particle distribution.
Thanks for the spelling corrections.
I'm curious though why you would post a 1922 translation. The details of that paper is outdated by later research.
