If the Local Conservation Postulate Predicts Einstein's Curvature, Why Does It Change the Cosmos?

This short comparative essay examines how the Local Conservation Postulate of Action—the principle that local conservation of energy–momentum precedes geometry—naturally reproduces Einstein’s spacetime curvature yet also predicts subtle cosmological deviations.
By comparing the geometric, informational, and conservation-based hierarchies that structure physical law, the paper argues that conservation is the truly fundamental principle, from which curvature and information follow as emergent properties.

The analysis clarifies why a postulate capable of deriving Einstein’s tensor equations cannot leave cosmology unchanged: it shifts the interpretation of dark energy, vacuum structure, and cosmic evolution from geometric assumptions to local conservation dynamics.

This essay serves as a conceptual bridge between J.P. Blankert’s trilogy on conservation-based spacetime foundations and later cosmological applications.
