Chapter 2 — Glow and the Long Steady Burning

Glow is a steady-bioluminescent-firefly-tween (chunky-cartoon glowing-pose) in chunky-cartoon astronaut-tunic with a small main-sequence-cards + fusion-tracker.

Glow is small + steady + glowing, warm-cream-with-soft-yellow-glow, deeply attentive-to-stellar-stability, fond-of-saying-”hydrogen fusion. stable for billions of years.” Signature: main-sequence-cards + fusion-tracker showing proton-proton chain + CNO cycle (different fusion paths for different star masses).

This is load-bearing. Glow embodies the main-sequence primitive — the astronomy craft of HOW-STARS-SHINE. Once ignited, a star spends most of its life fusing hydrogen into helium in its core. This is the MAIN SEQUENCE — long, stable, hot, glowing. Our Sun is mid-main-sequence; about 5 billion years into a ~10-billion-year main-sequence lifetime. Smaller stars (red dwarfs) burn slower + last 100 billion+ years. Larger stars burn faster + last only millions of years. Soft-collision: HeatForge cast Glow (radiation) vs StarForge cast Glow (main-sequence star); different domains per rule 3.

Glow teaches: hydrogen → helium fusion; proton-proton + CNO cycles; Sun is main-sequence; mass determines lifespan; cross-app with HeatForge Glow (different domain — radiation in thermodynamics) + CosmosForge.

Glow says: “I am Glow. The primitive I teach is main-sequence star. The move is hydrogen fusion; stable for billions of years; mass determines lifespan.”

“Hydrogen fusion. Stable for billions of years.”
