Einstein’s Elevator in Cosmology
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.
