Greetings, I have some questions concerning CDT: 1.Where can I find the newest updates on CDT (causal dynamical triangulation) and newest breakthroughs or aproaches to a theory of quantum gravity(as rare as they may be)? 2. What is a recommendable introduction to CDT (that is mathematical)? 3.What advantages does CDT have? I mean in comparison to say String theory or loop quantum gravity and all the other major theories. thanks for any help!
