Download or read book Causality-Violating Lorentzian Manifolds Admitting a Shear-Free Timelike Flow written by Matthias Plaue and published by Logos Verlag Berlin GmbH. This book was released on 2012 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Godel spacetime is an important cosmological solution of Einstein's field equations of gravitation. Although it does not offer a viable description of the physical universe, it illustrates the theoretical possibility of time travel. This work investigates world models similar to the Godel spacetime with particular emphasis on relations between kinematical properties (shear, vorticity, acceleration, expansion) and causality violation, i.e., the formation of closed timelike curves.
