Action and Reaction Without Braking: Mechanical Coupling of Spacetime in Astrophysical Dynamics

This manuscript presents a mechanical framework describing the interaction between mass and spacetime. The model explains why orbiting bodies, such as planets and stars, experience no drag, while highly dynamic events, such as imploding supernovae, naturally receive an energy boost. This duality offers insight into both stable orbital motion and explosive stellar phenomena, influencing the formation of neutron stars and black holes. The approach is based on first-principles mechanical reasoning, providing a predictive and unified framework without relying on phenomenological fits or unverified assumptions.
