Physics and Biology have long been treated as separate domains governed by contradictory logic: Physics by randomprobability (Quantum Mechanics) and Biology by randommutation (Darwinism). Hydrodynamic Quantum Cosmology (HQC) unifies these fields under a single structural axiom: The Universe is a Superfluid Plenum. By replacing the “Point Particle” with the “Vortex Filament,” we resolve Wave-Particle Duality via Screw Dynamics and Gravity via Tether Tension. Furthermore, we extend this hydrodynamic logic to biology, demonstrating via the principle of Natural Induction that life is not a random accident, but the viscoelastic relaxation of matter into the pre-existing geometric attractors of the vacuum.
