It is shown by the author that if gravitons are super-strong interacting
particles and the low-temperature graviton background exists, the basic
cosmological conjecture about the Dopplerian nature of redshifts may be false.
In this case, a full magnitude of cosmological redshift would be caused by
interactions of photons with gravitons. A new dimensional constant which
characterizes one act of interaction is introduced and estimated. Non-forehead
collisions with gravitons will lead to a very specific additional relaxation of
any photonic flux. It gives a possibility of another interpretation of
supernovae 1a data - without any kinematics. Of course, all of these facts may
implicate a necessity to change the standard cosmological paradigm. Some
features of a new paradigm are discussed here, too.
A quantum mechanism of
classical gravity based on an existence of this sea of gravitons is described
for the Newtonian limit. This mechanism needs graviton pairing and "an atomic
structure" of matter for working it, and leads to the time asymmetry. If the
considered quantum mechanism of classical gravity is realized in the nature,
then an existence of black holes contradicts to Einstein's equivalence
principle. It is shown that in this approach the two fundamental constants -
Hubble's and Newton's ones - should be connected between themselves. The
theoretical value of the Hubble constant is computed. In this approach, every
massive body would be decelerated due to collisions with gravitons that may be
connected with the Pioneer 10 anomaly. It is shown that the predicted and
observed values of deceleration are in good agreement. Some unsolved problems
are discussed, so as possibilities to verify some conjectures in laser-based
experiments.
