Chris @cjf.bsky.social · 06/10/2026Sometimes, when I have a giant world-changing idea, I put out a partial theory that is half-right to give people time to adapt. It'd be too much of a shock to just throw the truth out there. You can't just explain how maple syrup really interacts with society so you just say it goes well on pancakes 000
Greg P Stone @gregpstone.bsky.social · 06/10/2026And Brahe's own careful observations are what proved him wrong 000
Tony Fisk @arfisk.bsky.social · 06/10/2026I'm surprised (though, looking around, maybe I shouldn't be) this was still given credence in 1660. Brahe's sidekick Kepler made his name by describing the nested celestial solids that formed planetary orbits. Both made their living writing horoscopes. Then Kepler discovered ellipses. 100
