Generalization of the Coleman-Mandula theorem and the ring paradigm

Abstract One of the biggest open problems in cosmology is to explain the accelerated expansion of the Universe in the last 5 billion years. There were attempts to solve it classically, but one could also use quantum gravity. We introduce a new approach to the quantization of gravity, called the ring paradigm, according to which graviton is a phonon on a dynamical grid. We obtain, after the application to cosmology, a new model of dark energy, inside which we solve the old problem of the cosmological constant. The only way how to conceptually verify the ring paradigm is to show that there exists a certain generalization of the Coleman-Mandula theorem.
