It should be possible to detect the curvature of the surface of the earth locally. How could one do that? Is it related to the locally observed gravitational acceleration g?

Curvature tensor of the surface or of spacetime though? Idk how one would measure the curvature tensor of the surface directly but I assume you could construct it from studying the curvature tensor of spacetime, as that’s much easier to observe.

It’s the exact same as GR but a different manifold
