Galactic Rotation as Fossil Momentum from Primordial Dark Matter Torus

We present a new paradigm for galactic rotation curves based on the Vacuum Energy QuantaField (VEQF) theory, in which dark matter consists of inert, topologically stabilized solitonsformed in the early universe. We propose that a primordial rotating dark matter vortexunderwent fission into two stable toroidal structures: an inner torus that spun up duringcontraction, and an outer torus that expanded slightly but maintained coherence. The flat part ofrotation curves arises not from gravitational equilibrium with a dark halo, but from momentuminheritance: baryons in the disk acquire bulk velocity through shear coupling with the outertorus. Crucially, we predict that the radii of these tori are marked by dents (local minima in thederivative of the rotation curve), where dark matter density peaks and baryonic surface densityis suppressed. Additionally, we predict that stars and gas in the outer torus volume follow helicaltrajectories aligned with the toroidal energy density gradient, testable with future proper motionsurveys. Analyzing 85 galaxies from the SPARC sample with two dents, we find a statisticallyhighly significant suppression (mean ratio = 0.746, p < 0.0001) in baryonic surface density atthe outer dent radius compared to the surrounding disk. After filtering for physically resolvedtorus pairs (23 galaxies), the suppression strengthens to a mean ratio of 0.685 (p < 0.0001).We further validate the model against the Milky Way rotation curve from Gaia DR3 [Eilers et al.,2023], achieving good agreement without free parameters. While quantitative rotation curve fitsshow scatter due to galaxy-specific baryonic complexity, the Two-Torus Momentum InheritanceModel consistently reproduces the global shape of rotation curves using only dent-derivedstructural scales. This provides direct observational evidence for toroidal dark matter andvalidates our core ontology.
