Foundations of space and time [electronic resource] : reflections on quantum gravity / edited by Jeff Murugan, Amanda Weltman & George F.R. Ellis.

"After almost a century, the field of quantum gravity remains as difficult and inspiring as ever. Today, it finds itself a field divided, with two major contenders dominating: string theory, the leading exemplification of the covariant quantization program; and loop quantum gravity, the canonical sc...
