The book looks at how loop quantum gravity has emerged by following the work of two of its leading proponents, Carlo Rovelli and Lee Smolin, and assesses where the theory is now, and where it might be going.<\/p>\n<p>Although the concepts are \u2014 not surprisingly \u2014 mind-boggling, Baggott asks deep questions about the nature of the universe, what space is actually composed of, and the existence of time itself.
