Is there any direct transformation equations from schwarzschild coordinate components of time and distance to a flat Minkowsky space time? These basis vectors seem to be capable of producing the Shwarzschild metric: et=√(1-rs/r)cosh(ct) eT +√(1-rs/r)sinh(ct) eR er=(1/√(1-rs/r))sinh(ct) eT...

So, if we don't make all four dimensions same, then it shouldn't have any effect on invariancy of products, but plz try it, calculate the inner product of 4-velocity to itself (concluding C^2 as the result is impossible).

If we don't multiply time by the speed of light C, in Lorentz transformation equatins, the invariant tensor of U.U will not be equal to c^2. So it seems the coefficient of C is an obligation for parameter t. I thought it's just for visual convenience in graphs, besides C is not dimensionless.
