Graviton-graviton interactions are theorized to potentially enhance the gravitational binding of matter, particularly in weak gravitational fields, where these interactions may become significant. While light beams do interact gravitationally, the effects of graviton interactions are considered negligible far from compact objects. Deur's approach to graviton interactions has been proposed as a mechanism to explain galaxy rotation curves and cluster dynamics, suggesting it could offer insights into dark matter and dark energy phenomena. Despite its promise, Deur's work has not gained widespread attention in the scientific community, primarily due to its author's background in quantum chromodynamics rather than astrophysics. Overall, the discussion highlights the ongoing exploration of graviton interactions and their implications for understanding gravitational dynamics in the universe.
