The question arises, whether an acceptable physical theory should have a singularity, not even a coordinate singularity. The appearance of a singularity shows the limitations of the theory. In GR this limitation is the strong gravitational force acting near and at a super-massive concentration of a central mass. First, a historical overview is given, on former attempts to extend GR (which includes Einstein himself), all with distinct motivations. It will be shown that the only possible algebraic extension is to introduce pseudo-complex (pc) coordinates, otherwise for weak gravitational fields non-physical ghost solutions appear. Thus, the need to use pc-variables. We will see, that the theory contains a minimal length, with important consequences. After that, the pc-GR is formulated and compared to the former attempts. A new variational principle is introduced, which requires in the Einstein equations an additional contribution. Alternatively, the standard variational p | | 出版日期 | Book 2016 | | 关键词 | Extended General Relativity; Singularity Physics; Variational Principle General Relativity; Pseudo Comp | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-319-25061-8 | | isbn_softcover | 978-3-319-37426-0 | | isbn_ebook | 978-3-319-25061-8Series ISSN 2522-8900 Series E-ISSN 2522-8919 | | issn_series | 2522-8900 | | copyright | Springer International Publishing Switzerland 2016 |
