The Origin of Life: All It Took Was Hydrogen
Where did everything around you actually come from, and how do we know stars built it all from almost nothing?
You are made of atoms forged inside dying stars, and the path from a universe of nothing but hydrogen and helium to a planet full of carbon, iron, oxygen, and life is one of the most thoroughly documented stories in science. This video walks you through how the first stars ignited out of collapsing gas clouds, how nuclear fusion stitched light elements into heavier ones, how a supernova scatters those elements across space, and how spectroscopy, redshift, and the work of people like Edwin Hubble, Cecilia Payne-Gaposchkin, and Hans Bethe let us read all of it directly off starlight.
Every step of this process is observable, testable, and unavoidable given enough matter, gravity, and time.
Massive thank you to Leonard Tramiel PhD for reviewing and fact checking this video.
