What approaches to quantum gravity are QFT's?

What are the different approaches to solving quantum gravity that are in the framework of quantum field theory?

As I recall the original attempt to quantize gravity within QFT ran into trouble as it was shown to be non-renormalizable. Beyond that the "Quantum Gravity" wikipedia article has a pretty good survey of the basic directions of research and a bit more on the non-renormalizability issue.

Hi @Nickyv2423:
I think the discussion in the thread

https://www.physicsforums.com/threads/questions-regarding-hawking-radiation.898762/​

may be relevant to your question, particularly posts #12 through #15.

Hope this helps,
