Kinematic Genesis: A Six-Dimensional Kinematic Framework Connecting Quantum and Cosmological Scales

We present Kinematic Genesis (KG), a framework in which the phenomenology commonly attributed to dark matter and dark energy arises from higher-dimensional kinematics and a projection mechanism, without introducing new particle species and without modifying Einstein gravity at the fundamental level. The framework operates in a six-dimensional kinematic space with complex coordinates Z=x+iτZ = x + i\tauZ=x+iτ, where τ\tauτ represents hidden temporal degrees of freedom. The same geometric structure yields effective laws for rotationally supported systems, dispersion-supported systems, and the radial acceleration relation (RAR). At the effective level, a quantum sector illustrates how Schrödinger-type dynamics can emerge from diffusion in the extended space. A kinematic consistency relation, m⋅D⋅a0=ℏcH0/(4π)m \cdot D \cdot a_0 = \hbar c H_0 / (4\pi)m⋅D⋅a0=ℏcH0/(4π), links microphysical, galactic, and cosmological scales as a closure condition. We confront KG with SPARC rotation curves and Planck cosmological data, and we provide explicitly falsifiable predictions, including a redshift-dependent RAR, a0(z)=cH(z)/(2π)a_0(z) = c H(z) / (2\pi)a0(z)=cH(z)/(2π).
