In another thread I posed basically the folowing problem: Take the case of a stationary, non-rotating thin spherical shell of uniform area mass density - outer radius rb, inner radius ra, with (rb-ra)/ra << 1. There is consensus opinion that everywhere exterior and down to rb, spacetime is that of the vacuum SM (Schwarzschild metric), whilst everywhere interior to ra, flat MM (Minkowski metric) applies. Within the shell wall itself, there is a non-zero stress-energy and spacetime is neither vacuum SM or MM, but the particulars of that transition region is of no concern here. Assume then a modest gravitational potential such that rs/r << 1 close to the shell of mass m, with rs = 2Gmc-2. To a good first approximation there is a negligible relative drop in potential in going from rb to ra. Of interest is how spacetime affects the spatial and temporal components of a small test object placed in the SM or MM regions - all referenced to a distant stationary observer in asymptotically flat MM - the coordinate reference frame. Let the test object be a small perfect sphere (notionally "perfectly rigid") of diameter D as per coordinate measure in gravity-free space. It also doubles as a clock - emitting a fixed frequency f there. Next the sphere is placed in a stationary relative position: A: Resting just outside the shell at radius rb. It is here subject to SM B: Anywhere inside the shell at radius r<ra. It is here subject to MM. Required is the mathematically correct distortion factors |Dr'/D|, |Dt'/D|, |f'/f|, now observed for cases A and B, where: Dr', Dt', are the observed radial, tangential spatial measures in the gravity effected cases, and likewise for f'. Five values altogether are required: Case A: |Dr'/D|SM, |Dt'/D|SM, |f'/f|SM, Case B: |D'/D|MM, |f'/f|MM, - given that here flat MM implies Dr'= Dt' = D'. It should go without saying that only the underlying metric properties are of interest. Assume that any mechanical distortions due to direct or tidal 'g' forces are negligible or corrected for (e.g.; suspension in a flotation tank), and likewise for optical effects (gravitational light bending). Locally, no distortions would be apparent - only as seen 'from infinity' of course. This is an attempt to sort out certain claims that all commonly used coordinate systems will yield identical predictions.
