What is it about?
An alternative way to construct a quantum model of gravity is described, not by quantizing the classical model, but by introducing a graviton background, which has a low temperature but strongly interacts with any particle. Gravity in this case is the effect of screening the background of gravitons by bodies; several additional effects appear when photons or bodies move through the background. These small additional effects can be important for cosmology, since they allow us to describe the results of cosmological observations without dark energy.

Why is it important?
The procedure of quantization of gravity turns out to be redundant. Additional effects make the introduction of dark energy unnecessary.
Perspectives
Testing and confirming the hypothesis of the existence of a background of superstrongly interacting gravitons could lead to changes in our understanding of gravity and cosmology.
