WebThe stereographic projectionprovides a coordinate system for the sphere in which conformal flatness is explicit, as the metric is proportional to the flat one. In general relativityconformally flat manifolds can often be used, for example to describe Friedmann–Lemaître–Robertson–Walker metric.[5] WebMar 30, 2024 · The flat-Earth distance d will be expressed in the same units as the coordinates. If the locations are not already in Cartesian coordinates, the computational cost of converting from spherical coordinates and then using the flat-Earth model may exceed that of using the more accurate spherical model.

WebIn relativity, a flat spacetime is Minkowskian--there has to be some difference in signs between that of the time coordinate and those of the spatial coordinates. Whether the local tangent space is Euclidean or Minkowskian depends largely on context.
