A Short Survey of Time Machines

Abstract

In this paper a short survey of time machines (TM) is presented. Mathematical models such as Gödel’s spacetime, Kerr Spacetime, e.t.c., are discussed with emphasis on back in time (BIT) travel. In consummation, we give a representation of a modified source function, based on: (i ) Jauregui-Tsallis’ Conjecture and (ii) the fractional Dirac distribution contructed via Mandlebrot scaling. Notwithstanding that each representation has disparate dimensionality; i.e., d is not qual to D. Thus under cetain limiting values; q-parameter confinement and/or variance constraint, each TM is universally switched on for a given d/D. This means the original energy-momentum tensor (EMT) is recovered.
