Why NO infinities in LQG ?? what is the reason for LQG in 4-dimension to have NO infinities when doing calculations ?? , is it due to the fact that the VOlume and Area operators are Quantizied ? then if VOlume and Area are Quantizied, there should be a MINIMUM or quantum of area or volume we can detect and hence there would be a natural UV Cut-off , is this correct ?? by the way , a GOOD book to learn LQG ??, i have notions of SR , GR and Quantum mechanics... thanks.
