A "timeline of transparency"—showing the transition from a glowing orange wall of plasma to the first streaks of clear light, eventually fading into the "Dark Ages" before the first stars turned on.
How 380,000 years of chaos became the blueprint for the cosmos. The Core Narrative Precision cosmology : the first half million years
Contrast the "guesswork" of 20th-century astronomy with modern missions like Planck . We’ve moved from "the universe is roughly 10–20 billion years old" to "it is exactly 13.787 ± 0.020 billion years old." Key "Stats" to Highlight A "timeline of transparency"—showing the transition from a
Explain Baryon Acoustic Oscillations . Early matter didn't just sit there; it rippled like sound waves in a pond. The "size" of these ripples today tells us exactly how fast the universe is expanding. Precision cosmology : the first half million years
