摘要

M-theory and loop quantum gravity (LQG) are usually accounted as the favored candidates to solve the problem of quantum gravity.Nonetheless,both the frameworks are still concerned with several technical and conceptual issues,and the lack of any direct experimental data on the string/Planck scale only allows to focus on the mathematical self-consistency of the two frameworks.It is also commonly retained that these theories cannot be compatible with one another.Reasons to prefer M-theory to LQG are usually individuated in the unification of all particles and interactions,and in the convergence-at the low-energy perturbative limit-to general relativity.On the other hand,LQG has the remarkable advantage to be background independent and to provide a fully non-perturbative theory-unification models were also proposed in LQG [1-3].
