Piareround had some questions about LQG. I have to go out for the next hour or so. Maybe someone will take a look and respond. Or I will when I get back.

... as I was reading your thread I realized that I assumed two things:
First, quantum loop gravity only requires 4 dimensional Minkowski Space
Second, that quantum foam actually plays a role in quantum loop gravity.
So I was hoping you could help me with the following questions:
- Are there any limits, such as a minimum or maximum, on the number of dimensions that quantum loop gravity, independent of string theory, would require?
- Is their a relationship between quantum foam and quantum loop gravity? If so, what role exactly does quantum foam play in quantum loop gravity theory? If not, does quantum loop gravity, replace quantum foam with something analogous to quantum foam purpose in solution the Klein-Gordon Equation(*)?
