## Main Question or Discussion Point

From the "Intuitive content of Loop Gravity--Rovelli's program" thread:

Koch does show how others have proposed emergent quantum mechanics:

How seriously is this idea being taken within the quantum gravity community? Does anyone know of any other papers that are approaching quantum gravity in this way?

From the paper:http://arxiv.org/abs/1004.2879

Quantizing Geometry or Geometrizing the Quantum?

Bejamin Koch

(Submitted on 16 Apr 2010)

The unsatisfactory status of the search for a consistent and predictive quantization of gravity is taken as motivation to study the question whether geometrical laws could be more fundamental than quantization procedures. In such an approach the quantum mechanical laws should emerge from the geometrical theory. A toy model that incorporates the idea is presented and its necessary formulation in configuration space is emphasized.

I haven't seen any discussion of this paper here or the approach: starting with the proposition that geometry is fundamental with quantum mechanics being emergent.Given the problems in applying the laws of quantum mechanics to the geometry of space-time we want to ask the following question:

“Could it be that (classical) geometry is more fundamental than the rules of quantization?”

Koch does show how others have proposed emergent quantum mechanics:

He then goes on to list papers by many other physicists who have proposed an emergent quantum mechanics.The idea that quantum mechanics might not be fundamental but rather emerge from an underlying classical system has been proposed in various ways.

How seriously is this idea being taken within the quantum gravity community? Does anyone know of any other papers that are approaching quantum gravity in this way?
