30 “Now-False Facts” That Were Really Taught In Schools, But Did Not Stand The Test Of Time

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.

That Christopher Columbus was a great guy and all the natives rose up in celebration when he came.

Plate tectonics. When I was in the 1st grade I saw a map of the world and I told my teacher that it looks like all the continents used to fit together, but they moved apart.

My teacher laughed at me and loudly proclaimed I was an idiot with a wild imagination.

School kids laughed.

Jokes on them.

Playing with computers is a waste of time and won’t lead to a career. Said to me by a very old, and bitter teacher. 25 years in IT and counting.

I was always taught Mississippi’s secession from the union in the civil war was to preserve state’s right to be independent and nothing at all to do with slavery. That Confederate heritage was about family and not racism.

[Slavery is mentioned in the very first sentence of the first paragraph of the letter of secession as the primary reason.](https://avalon.law.yale.edu/19th_century/csa_missec.asp) They decided if they couldn’t own humans anymore it would crash the economy.

When I was a kid, the Giant Squid had never been captured or photographed, and some people talked about it like it was el chupacabra. My little brother always said he’d be the first person to get footage of one. Sadly, it has since become an ordinary animal that we know exists. RIP the Kraken

That Columbus was the first European to step foot in the new world. Once found an old textbook that stated this. This was prior to the discovery of the Viking settlement in Nfld.

So many things. The lifetime of facts is shorter than you’d think. Among them:

* You use 10% of your brain (was in a textbook)
* Model of the atom
* What composes a healthy diet
* Various histories from how dinosaurs looked to what life was like in the Middle Ages
* Causes of ulcers, poor vision, acne..

Pompeii was buried slowly by falling ash. They pointed out that remnants of people were found, right in the middle of doing things, but didn’t realise this contradicted the burying being slow. It’s now thought that it was buried very quickly by pyroclastic flows – superheated gas travelling over 200mph.

My f*****g history teacher taught us how great of a president Woodrow Wilson was.

I later learned he was a literal white supremacist who admired the KKK and an overall giant racist even for his time.

Bohrs Atomic Model

Taste buds

We only have 5 senses

Brain cells, once lost, are gone.

Dogs and cats see in black and white.

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.

Glass is actually a liquid, which is why old windows look droopy.
