Fig. 2: Possible world models according to the big vang theory ( q = delay parameter)

Surprisingly, the GTR leaves open, which time parameter must be applied [11], p. 225:
„The laws of the GTR are independent on the parameterisation of the time.“
This degree of variance must be put to use for additional solving variations of the field equations, even when non-foreseeable risks are connected to this [12], p. 10:
„The possibility of an arbitrary definition ( of the time measure) could be used  to give the theory an especially simple, expedient and lucid shape. It could also be that definitions at such a fundamental term as the time has hard to foresee consequences for the total structure of physics, and that the range of the observable and explainable phenomena depends essentially on these definitions.”
