Where to search for quantum gravity

Abstract

The well known expectations to unify general relativity with quantum mechanics did not give some essential results up to now. If quantum gravity has such a poor set of tiny effects as in existing models, it may not be of great interest for physics. But there is another approach to quantum gravity, in which it seems to be a common ground of general relativity and quantum mechanics rather than their consequence. Important features of the author’s model of low-energy quantum gravity, such as the quantum mechanism of classical gravity, the quantum mechanism of redshift and the specific relaxation of any photonic flux, are described here. In the model, the Newton and Hubble constants may be computed, but the latter is not connected with any expansion. The model fits SN1a and GRB observations very well without dark energy. Some possibilities to verify the model in ground-based experiments are discussed.
