🌌 Supernova Hubble Diagram: Dark Energy, Equation of State and Age (2D)

Plot of how far away standard-candle supernovae appear at each redshift in a universe made of matter, curvature and dark energy, drawn with simulated measurements and your model against the matter-only case. Set the Hubble constant, the matter density, the dark-energy equation of state, the curvature, the number of supernovae and their scatter, and see the luminosity distance, the deceleration parameter, the age of the universe, the redshift at which the expansion turns to acceleration and how well the model fits. The matter-only distance, the de Sitter distance, the age formula and the low-redshift expansion are checked numerically, with four in-page numerical checks.
