SINGULARITAS RUANG-WAKTU BERMETRIK KERR, KERR-NEWMAN, DAN DE-SITTER DALAM TEORI RELATIVITAS UMUM; SPACETIME SINGULARITY ON KERR, KERR-NEWMAN, AND DE-SITTER METRIC IN GENERAL THEORY OF RELATIVITY

Spacetime singularity in general theory of relativity has been considered. The definition of singularity was used based on the Kretchmann scalar criteria. The character of spacetime geometry in the region around singularity for the three spacetime metric has been identified according to calculation. The three spacetime metric are Kerr metric, Kerr-Newman metric, and de Sitter metric. The dynamics of test particle in the region around singularity has also been considered (there is no outside force acted on the test particle). The discussion was concerned with the geodesic equation for all the three metric.
