Slaying the Twin Dragons: Dark Matter and Dark Energy as Time Emergence Artifacts of the Universal Cascade Law

Description Dark matter and dark energy are not separate mysteries. They are twin artifacts of a single assumption: that time is fully expressed everywhere and at every epoch. This paper presents two independent tests of the time emergence hypothesis using two public datasets. Test 1 — Dark Matter: 175 galaxy rotation curves from the SPARC database. The dual attractor architecture is confirmed at p = 10⁻⁹⁰. The Feigenbaum family constant δ(z=6) = 9.2962 appears in acceleration space at p = 3 × 10⁻¹¹. The characteristic acceleration a₀ is derived from Feigenbaum constant space to within 3.8%. The time emergence gradient shows τ < 0.5 at the edges of 117/175 galaxies. Test 2 — Dark Energy: 1,701 Type Ia supernovae from Pantheon+. A zero-free-parameter time emergence model, derived entirely from ln(δ) = 1.5410, fits the data to within 3.2% of ΛCDM — which requires two fitted parameters and 68% of the universe to be unknown energy. The transition redshift z_t = 1.449 falls within 6.4% of ln(δ). One mechanism. Two scales. Two dragons. One sword. The universe is not 95% dark. We were measuring with the wrong clock.
