Radiation Cooling
Definition
Radiation Cooling is the fate of a universe's first light: T_γ = T_γr · aᵣ / a, the light released at the Physical Nova carried with the space and stretched with it, so its temperature falls as the scale factor grows. Ours was released at about 3,000 K some 380,000 years in and has been stretched about 1,100 times since: 2.7255 K today, the microwave background (Fixsen 2009). The glow is white-hot at its release, cherry red at two and a half times that scale, about 1,200 K, and then dark to any eye: the sky goes black through the dark ages until the first stars. The game draws the whole torus glowing at the big bang and cooling by this law. It connects to Primordial Wave Stretch, Physical Nova, Matter-Era Expansion and Dark Ages.

The first light cools as the space that holds it grows
Where:
- T_γ [Θ] — the temperature of the first light now
- T_γr [Θ] — its temperature when it was released
- a [∅] — the scale factor now
- aᵣ [∅] — the scale factor at its release
