What It Actually Takes to Escape the Solar System... And Why We'll Never Make It

Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/3enq56n... Everyone knows the number that gets you off the Earth: eleven point two kilometres per second. Almost nobody knows it is the smallest of at least six bills, and the only one anyone has ever paid. Past it lies a wall made of wind, and a shell of ice half a light-year thick. So what would getting out actually cost? Tonight we climb the whole ladder in order — the pad, the Sun's grip, the heliopause, the Oort Cloud, the empty light-years, and every engine anyone has ever seriously proposed. Get comfortable and let this long climb out of the solar system keep you company tonight. Subscribe to Sleep in Orbit if you like falling asleep somewhere far from Earth.
