An interactive Lorentzian diagram in Minkowski space ℝ^(1,1), visualizing the intersection between the hyperboloid
ℍ¹ = {(r,t) : t² − r² = 1, t > 0}
and the embedded curve x ↦ (√x, x).
The condition (√x, x) ∈ ℍ¹ is equivalent to x² − x = 1, whose unique positive solution is x = φ = (1+√5)/2. The simulator identifies (√φ, φ) as the unique intersection of the curve with ℍ¹.
At this point, the Lorentz factor equals φ itself: cosh(η) = φ and sinh(η) = √φ, where η = artanh(1/√φ) ≈ 1.0613 is the rapidity. The golden ratio appears as the γ-factor of a canonical boost on ℍ¹.
The visualization includes the hyperbolic (ℍ¹), null (t = ±r), and spacelike (dS¹) regions, along with real-time evaluation of the quadratic form Q = t² − r², rapidity η, and the ratio r/t.
A 1+1 dimensional case of the dual level set structure in Theory #18. Part of the Captain Cookie Face Universe (CCFU) framework.
