But actually it's been solved many times, and in ingenious ways. Some of those solutions are incredibly useful, and some are incredibly bizarre.Hosted by Matt O'DowdWritten by Matt O'DowdGraphics by Leonardo Scholzer and Adriano LealPost Production: Yago Ballarini, Max Willians, Pedro OsinskiDirected by: Andrew KornhaberExecutive Producers: Eric Brown and Andrew KornhaberEnd Credits Music by J.R.S.

Within it were equations of motion and gravity that transformed our erratic-seeming cosmos into a perfectly tuned machine of clockwork predictability. Given the current positions and velocities of the bodies of the solar system, Newton’s equations could be used in principle be used to calculate their locations at any distant time, future or past. I say “in principle” because the reality isn’t so simple. Despite the beauty of Newton’s equations, they lead to a simple solution for planetary motion in only one case - when two and only two bodies orbit each other sans any other gravitational influence in the universe. Add just one more body and in most cases all motion becomes fundamentally chaotic - there exists no simple solution. This is the three-body problem, and we’ve been trying to solve it for over 300 years.Special Thanks to Our Patreon Supporters:Big Bang Supporters: Alexander TamasDavid BarnholdtDavid NicklasFabrice EapJohn SJuan BenetMorgan HoughQuasar Supporters:Christina OegrenMark HeisingVinnie FalcoHypernovaChuck ZegarDanton SpiveyDonal BotkinEdmund FokschanerHank SJohn HofmannJohn PollockJohn R.
