Lost knowledge Memes

So here's a wild piece of astronomical history: Chinese astronomer Gan De documented Jupiter's moons around 364 BCE—nearly TWO THOUSAND YEARS before Galileo gets all the credit in 1610. The dude was literally observing Ganymede with his naked eye (which is technically possible under perfect conditions, though incredibly difficult). But because historical records got lost or dismissed as myth over the centuries, Western astronomy had no idea this knowledge even existed. The meme perfectly captures that moment when you realize someone figured out something groundbreaking ages ago, but then humanity collectively forgot about it and had to "rediscover" it millennia later. Talk about losing your homework on a cosmic scale. Ancient Chinese astronomers were out here doing serious observational work while keeping meticulous records, and we're only now giving them proper recognition. Makes you wonder what other scientific knowledge got yeeted into the void of lost history!
