How Galaxies Are Born Explained — Narrated by David Attenborough | Science Documentary 2025 ► Subscribe Now: @asdtheexplainer How does order emerge from cosmic chaos? How do vast islands of stars arise from clouds of gas and darkness? In this documentary, we explore the extraordinary story of galaxy formation — the process by which the universe transformed from a nearly uniform sea of matter into the majestic spiral and elliptical galaxies we see today. In the aftermath of the Big Bang, the universe was hot, smooth, and almost featureless. Tiny fluctuations in density, amplified by gravity and guided by dark matter, slowly grew over billions of years into the first galactic structures. What sparks the birth of a galaxy? What role does dark matter play in shaping their form? And how do galaxies evolve across cosmic time? We journey through the early universe, exploring vast halos of invisible matter, collapsing gas clouds, and the ignition of the first stars — whose light marked the end of cosmic darkness. From the first protogalaxies… To graceful spiral arms and giant ellipticals… To collisions and mergers that reshape the universe… This film reveals how galaxies are not static objects, but living systems — growing, colliding, and evolving over billions of years. Join us as we witness the universe learning to organize itself… the birth of cosmic cities of stars… how galaxies are born. 🎵 Music credits: Lost Frontier by Kevin MacLeod is licensed under a Creative Commons Attribution 4.0 license. https://creativecommons.org/licenses/...
