The myth that glass is a very thick liquid. It's actually much weirder than that. https://gizmodo.com/the-glass-is-a-liquid-myth-has-finally-been-destroyed-496190894

I have one that was proven false, and then later re-proven true: the existence of the brontosaurus.

When I was in elementary school, we were taught that they existed, they were big, etc. Then, at some point while I was in college, I discovered that actually what we thought was a brontosaur was a brachiosaur or an apatosaur. And then, when my kids went to school and learned about the brontosaur, I discovered that actually, they did exist!

Some children are taught in school that God created the earth. Some of us were allowed to learn that humans cannot effect climate change, allowed to discuss it openly, and allowed to graduate with that idea without ever being corrected. Children are being taught today that slavery and colonialism were good things for some people.

"This is the best time of your life, it will never be as easy."
I wasted more time at school than at work and I didn't have Fridays off, so that was a lie.

In my college Econ 101 class I was taught that "economic liberalism" would lead to political liberalism. I knew that was a myth back then, but my professors insisted. Twenty years later we've got economic nationalism and political fascism taking over everywhere.

Racism used to be a problem until Lincoln and MLK fixed it.

Gravity Waves didn't exist according to my highschool science teacher

I was taught that the moon landing was fake.

That fluoride and vaccines are bad for you… tbh, I only believed it for 2-3 weeks until I did my own research, but it was a frightening clarification. Didn’t believe that teacher a single word after that.

There are 10 Commandments.

No - there's 14.

And most of them also have sub-commandments, just to confuse it further.

Junk DNA.

By the time I was in school the Bohr model was already proven inaccurate, but was taught anyway because the orbital model is too esoteric for teenagers 🙄.

I learned that it’s not ok to be intelligent but completely incapable of remembering to do things or remembering the things that the teachers thought it was important for me to remember.

That adults are mature and know what they are doing.

Allergies are entirely genetic. Apparently they ain't or so I hear but it's a bit above my paygrade biology wise

The moon was spun out of the same stuff as the earth. That was fact in the early years of my education. A few years later there were multiple theories: co development, captured a wandering planetoid, the Thea impact, and a fourth one I can’t remember but I think it was something dumb like planetary mitosis. By the time I graduated the Thea impact was considered the only viable theory.
