This discussion explores the relationship between gravity and the conservation of energy, raising questions about the nature of gravitational forces, spacetime, and energy transfer. Participants delve into theoretical implications, potential models, and speculative ideas regarding gravity's role in the universe.
Participants do not reach a consensus, as multiple competing views and hypotheses are presented regarding the nature of gravity, energy conservation, and the implications for dark matter and dark energy.
The discussion highlights limitations in understanding the energy dynamics associated with gravity, the assumptions underlying gravitational theories, and the unresolved mathematical aspects of spacetime distortion.
In the Newtonian limit all gravity is encoded in ##g_{00}(x)##, which is more like "compression" (of time) than like curvature.PeterDonis said:"Compression" is not a good description. "Curvature" is better
