In comoving coordinates, the metrics of gravitational and cosmological models are brought into canonical form. From this, the FWR curvature parameter is calculated, and it is demonstrated that k = 0 does not correspond to a flat model, but to a spatially positively curved geometry with free-falling reference systems. This is also in line with Einstein's elevator theory. Furthermore, we demonstrate that our subluminal universe is linked to the R = ct Melia's approach is based on the assumption that k = 0 is concerned with a free-falling system in the sense that it has been defined above.
