Cosmology SHOWCASE

What you are seeing: the universe at large, rendered through four modes (Expansion, Fate, CMB, Inflation). The same cosmological parameters Omega_m and Omega_Lambda are shared across modes, so you build one mental model from the lattice's expansion to its inflationary origins. Drag the canvas to orbit the camera, scroll to zoom

Figure 1. Cosmology, mode-switchable laboratory. Method: shared friedmann-cpu engine (RK4 integration of a(t) from the Friedmann equation), a Canvas2D comoving galaxy lattice projected through an orbit camera with proper separations scaled by a(t), deterministic value-noise CMB temperature field, closed-form slow-roll inflaton for V(phi), n_s, r.

WHAT TO TRY

Switch between the four modes: the expanding lattice, the four fate scenarios, the last-scattering CMB sphere, and slow-roll inflation, all driven by the same Omega_m and Omega_Lambda.
Tune Omega_m against Omega_Lambda: a matter-only universe recollapses or coasts, while our Lambda-dominated one accelerates. The fate readout names the destiny you have dialled.
Open Inflation mode: the potential V(phi) sets the spectral index n_s and tensor-to-scalar ratio r, the numbers the CMB measurements pin down.
