It is said that a flaw in string theory is that it is background dependent, whilst loop quantum gravity isn't background dependent. I don't see why this would actually be a flaw, because from what I understand is that background dependence means that the theory relies on a background of spacetime, so why should it necessiraly be 'bad' that it depends on this background? If string theory would be proven to be correct, being background dependent, would it be a sort of incomplete theory? Would it somehow be better if it was background independent? I would appreciate any answers.
