Mapping the Expanding Universe: Redshift, Standard Candles, and the Distance Ladder

Tonight, drift with a calm guide through how the universe expands—from redshift and the stretching of light, to Hubble’s Law and the steady slope that links distance to cosmic recession. We’ll move gently through the tools astronomers use to measure the deep sky: standard candles like Cepheids and Type Ia supernovae, and the careful chain of methods known as the distance ladder. Along the way, we’ll keep everything slow, clear, and grounded in real physics—an immersive 2–3 hour science sleep documentary designed to soften the mind while exploring the scale of the cosmos. This video is created for educational purposes to explore scientific ideas in a peaceful, sleep-friendly format.
