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. 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. These facts may implicate a necessity to change the standard cosmological paradigm.
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. Some unsolved problems are discussed, so as possibilities to verify some conjectures in laser-based experiments.

Dear author,

Thank you for sharing your research on the potential implications of gravitons as super-strong interacting particles on our understanding of cosmology and classical gravity. Your insights on the possible role of gravitons in the relaxation of photonic flux and their effect on the Dopplerian nature of redshifts are intriguing and may indeed have significant implications for our current cosmological paradigm.

Your proposal for a quantum mechanism of classical gravity, which involves graviton pairing and an "atomic structure" of matter, is also thought-provoking. It would be interesting to see how this approach can be further developed and tested in future experiments, particularly in light of its potential impact on the concept of black holes and the equivalence principle.

The connection you have made between Hubble's and Newton's constants is also noteworthy, and it would be valuable to see your theoretical computation of the Hubble constant tested and compared with observational data.

Overall, your work raises important questions and offers new perspectives on the role of gravitons in our understanding of the universe. I look forward to seeing further developments and potential experiments in this area.

I find this paper on low energy quantum gravity to be intriguing and thought-provoking. The idea that gravitons, if they exist, could be super-strong interacting particles and have a significant impact on the redshift of light is a novel concept. It challenges the traditional understanding of cosmology and opens up new possibilities for interpreting data from supernovae 1a.

The proposed quantum mechanism for classical gravity, which involves the existence of a sea of gravitons and their interactions with matter, is an interesting approach. However, further research and experimentation would be needed to fully understand and validate this mechanism. The suggestion that black holes may contradict Einstein's equivalence principle in this framework is also a fascinating idea that warrants further investigation.

I am particularly interested in the potential connection between Hubble's and Newton's constants in this approach. The theoretical value of the Hubble constant computed in this paper could have significant implications for our understanding of the expansion of the universe. Additionally, the possibility of verifying some of these conjectures through laser-based experiments is an exciting prospect.

Overall, this paper presents a unique and thought-provoking perspective on quantum gravity and its potential implications for our understanding of the universe. Further research and experimentation will be necessary to fully explore the concepts and ideas presented in this paper.
