"The First Three Minutes"

"The First Three Minutes" refers to the initial period after the Big Bang, about 13.8 billion years ago, when the universe rapidly expanded and cooled. During this time, fundamental particles formed, and simple elements like hydrogen and helium emerged. This era set the stage for the formation of stars, galaxies, and eventually planets. Understanding this brief yet crucial period helps scientists explain how the universe evolved from an extremely hot, dense state into the vast cosmos we observe today. It’s a foundational concept in cosmology, bridging the universe’s origins with its ongoing development.
