| Summary: | The mathematical transformations used in a previous paper by the author enable one to recast the Kerr-Newman metric for the gravitational field of a charged and rotating mass in two new forms which satisfy physically judicious requirements necessary for a relevant system of reference to be realizable with the aid of real bodies throughout all space as distinct from the initial Kerr-Newman metric. The new metrics are physically admissible for any angular momentum of the rotating central mass provided the charge of the mass is not too large. Properties of the metrics are studied. One of the metric is preferable from the physical point of view because all coefficients in the metric are non-singular except for the points where the rotating disk creating the gravitational field is located. The results of the present paper show that there are no black holes around rotating masses, be they charged or noncharged. Keywords: General relativity, Metrics for vacuum, Kerr-Newman metric |
