From the Big Bang to Today: Cosmic Expansion, the CMB Afterglow, and the Birth of Galaxies

Описание: Drift through the story of our universe from the Big Bang to the sky we see today. In a calm, sleep-friendly pace, we explore cosmic expansion, the cooling of space, and the faint afterglow of the Cosmic Microwave Background (CMB). Follow how tiny early fluctuations grow into vast structures—stars, galaxies, clusters—guided by gravity and shaped by dark matter and dark energy. Along the way, we connect key observations and evidence, from redshift and CMB patterns to large-scale structure and gravitational lensing, building a coherent picture of cosmic history. This video is created for educational purposes to explore scientific ideas in a peaceful, sleep-friendly format.
