Current progress in quantum gravity?

[Haorong Wu]

TL;DR Summary

Where can I find a review of the current progress in quantum gravity?

Hi, there. I am interested in quantum gravity. But I am not sure how to find review papers about its recent developments. I tried "quantum gravity" on google scholar. But I could not find a suitable review other than that about loop quantum gravity. I am not sure what are the other approaches to this problem and I am looking for papers covering them.

BTW, I have heard loop quantum gravity several years ago. In my memory, this theory seemed not to give any new predictions and is questionable. What is its status now in the physics community?

Thanks.

Have you already read this current thread in the BTSM forum?

Summary:: One of the leading researchers in Loop Quantum Gravity discusses existing observations that should guide future quantum gravity research in a three page paper.

Rovelli points to three pieces of existing observational evidence that should guide future quantum gravity research. Bottom line:

* abandon Lorentz invariance violating quantum gravity theories,
* abandon supergravity and string theory,
and
* stop working on the anti-deSitter/conformal field theory relationship in gravity and cosmology work (leave it to the condensed matter physicists who have legitimate uses for it).

If you want an overview, this talk from Hermann Nicolai might be a good place to start:

Thanks, guys. I will check all those information.
