The cosmos contains everything we know, from planets and stars to galaxies stretching across unimaginable distances. This episode explores the structure of the universe, how our understanding of it has changed over time, and the enormous scales that shape our view of space. Along the way, you’ll hear about galaxies, cosmic distances, the observable universe, and humanity’s attempts to understand our place within it.
It’s steady and consistent, with no whispering and no sudden changes, just enough to give your mind something to follow as you wind down. Happy sleeping!
