Archimedes' Cosmic Law

This speculative cosmological report proposes a generalized form of Archimedes' principle for gravitationally bound structures within the quantum field of space. The principle states that galaxies and larger formations displace quantum vacuum pressure (such as relic neutrinos), and are quantumly buoyed in proportion to the displaced mass. This concept introduces a new framework for understanding local expansion dynamics and the emergent behavior of the cosmological constant. Quantitative examples from the Milky Way to the Laniakea supercluster are provided.
