image I have heard the following criticism of loop quantum gravity: ``Loop quantum gravity is certainly physically wrong, because: (1) It is not supersymmetric, and (2) it is formulated in four dimensions''. But experimentally, the world still insists on looking four-dimensional and not supersymmetric. In my opinion, people should be careful to not be blinded by their own speculation and inadvertently mistake interesting hypotheses (such as supersymmetry and high-dimensions) for established truths.
