Hypergravity and Categorical Feynmanology
  We propose a new line of attack to create a finite quantum theory which includes general relativity and (perhaps) the standard model in its low energy limit. The theory would emerge from the categorical approach. A structure is observed on the category of unitary representations of the lorentz group which we call hypergravity. This, combined with a study of the relationship between Feynman diagrams and words in tensor categories, leads to the proposal.
