| contents | We comment on the fact that certain mathematical models that have been proposed in the quantum gravity literature, may not be subject to experimental checks, even if they turn out to be mathematically well defined. This means that they would be indistinguishable from other models, with a smaller number of quantum states. These considerations follow from very general properties of quantum measurement theory and classical gravity. |
