Consistency between string/M-theory and LQG
Is there a reason that LQG and other QG theories cannot be consistent with string/M-theories? My naive understanding is that the former theories approach the problems of QG and unification from the perspective of quantising GR, while the latter start from QFT. If both are rigorously defined purely from well-tested aspects of GR and QFT respectively then presumably they may both provide complementary descriptions of the same physics. On the other hand if either or both is built on unproven postulates then one, or both of them may be incorrect. I'd be interested to hear the views of some QG and string theory experts...
