The vacuum is a superfluid.

Same hydrodynamic patterns in Superfluid Vacuum Theory — vortex flows and phonon waves at microscopic vs cosmological scales
Superfluid Vortex Theory (SVT) models the vacuum as a coherent quantum fluid governed by the Gross - Pitaevskii equation. Particles are topological vortices, gravity is an acoustic metric, and dark matter, dark energy, and the Higgs sector all emerge from the same low-energy hydrodynamics.
Core mathematics
Full theory page →Three equations do most of the work in SVT.
The GPE governs the vacuum order parameter. Phonons reproduce QM; vortex cores define the Planck scale.
A moving background flow v(x) induces a Lorentzian metric for phonons — analogue gravity with a natural horizon at |v|=c.
RG flow of the condensate coupling fixes G₀ today and G(z=12) ≈ 3 G₀, explaining the JWST early-galaxy excess.
From GPE to Schrödinger, vortex lattices, acoustic metric, and topological particle masses.
Which physics puzzles SVT addresses: Hubble tension, JWST early galaxies, dark energy, mass gap.
