Cosmology and the Big Bang

~60 min · 15 stations

Cosmology and the Big Bang is a self-paced learning path in Astronomy & Space Exploration, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the fundamental premise of the Big Bang theory; contrast static universe models with dynamic expansion theories; interpret light data to determine galactic movement patterns.
