When I was in elementary school, teachers told me that Columbus discovered America. When I was in high school - that there are nine planets in the Solar system, including Pluto. After algebra lessons in high school, I knew for sure that Fermat's Last Theorem had no proof...
Do you know what those all have in common? Yes, that's right - some time passed, literally several years, and everything that the teacher said turned out to be untrue. More precisely, not even a lie - just science convincingly refuted everything that was considered an indisputable truth earlier. And I'm not alone here - in this thread in the AskReddit community, many netizens share similar stories from their own school years.

Wolf packs have alphas. Turns out wolves are a lot like humans and the 'alphas' are simply the sire and b***h of the wolf pack (their parents) and they follow them and respect them because they're the ones who taught them how to hunt and survive.

When my mom graduated high school in 1944, the nuns were teaching that the atom could not be split. I think the Manhattan Project was already extant at the time. Correct me if I'm wrong, I did see Oppenheimer twice.
