The fact that different sign conventions are used for the same quantities in the physics literature can make the comparison of results difficult. In this appendix, we discuss these conventions. In particular we will define 10 distinct sign choices si. In this book, we take si = +1 for all cases.

A.1   Spacetime and gravity

The first set of conventions is related to the spacetime metric and curvature tensor. On the inside cover of the classic text of Misner, Thorne, and Wheeler [361], three signs are defined to discuss these basic conventions for general relativity. We need additional signs for quantities defined in local Lorentz frames and for ...
