Abstract

We present a cyclic symmetry type II vacuum spacetime admitting closed timelike curves (CTCs) which appear after a certain instant of time, i.e., a time-machine spacetime. The various authors in past have considered the 2D and 4D flat generalization of Misner space, but in the present work, we have considered the curved spacetime generalzations of 4D Misner space, and is asymptotically flat radially

Subject Areas

closed timelike curves; Misner space; vacuum spacetime

Comment: Dear Editor,
An Appendix "A' is added in this version. The original paper (without appendix) was appeared in "RESEARCH JOURNAL OF CONTEMPORARY CONCERNS" Volume 10 & 11 (B), pp. 171-175 (2016) published by COTTON COLLEGE RESEARCH COUNCIL. A duplicate of this work was recently published in IJMPA (Int. J. Mod. Phys. A 36 (03), 2150017 (2021) ; DOI: 10.1142/S0217751X21500172) by other author. For clarification I have attached a supplement file herewith.
