Put your scientific misconceptions you had in childhood here

I just recently remembered how big of a deal cryptozoology was for me as a kid. A part of me today wishes the Loch Ness Monster was real.

I used to think that Nuclear Power Plants had something to do with some sort of an unique plant type.

I used to think it was possible to “split,” as in sounding like a group of people, one’s voice.

I used to think it was possible to talk and think at the same time (as in comic(except manga))

I used to think that if you made as many good deeds as sins in your life, you’d become a ghost haunting the world.

it is though?? are you not able to? i do that like, several times a week? sure, it takes more effort than one at a time, and a bit of planning out what you’re going to say, to speak and think at the same time, but it’s still possible.

Not sure why but I used to think that GTA was some sort of a “life simulator” like the Sims or something.

Oh, here’s one I remember which many of you may think too: while they can absorb oxygen underwater, a lot of amphibians actually do “need” to breathe air. Frogs can stay underwater a long time, but especially if they are very active, it won’t suffice to just absorb oxygen through their skin.

i thought forests provided most of the world’s oxygen, not remotely true, the ocean produces somewhere between 50% and 85%, tho i feel this one is common

Yeah, I believed in this for a long time too

I thought that animals with gills split the hydrogen and oxygen out of water molecules to breathe. You know, people say there’s oxygen in water, and people say water is made out of oxygen, probably talking about the same thing. I always wondered where the hydrogen went.

I have a hard time imagining sizes. I knew that the meteor that killed the dinosaurs was near the Yucatan peninsula. For some reason, I thought the Gulf of Mexico was the crater that it left behind[1]. Its not perfectly spherical[2], but I though the continents must have moved a bit since then.

I had heard in a documentry that the meteor was as big as Mount Everest, and I confused the Everest with the Himalayas. The Everest is too small to see on the map, whereas the Himalayan Plateau is as big as the dwarf planet Ceres[3][4].

I also imagined T-rex to be a kaiju that is as big as buildings[5]. But its height is basically the same as a giraffe[6]. If you stayed below it, its abdomen would be right above your head. It would be a very low ceiling. Only the herbivorous quadropedal dinosaurs reached extreme sizes[7]. The biggest dinosaur is 1.2 giraffes tall, but thats only the height at its shoulders, and depending on how vertical you assume they hold their necks, you can add a few more giraffes to that.

Pretty sure it was larger since Everest is mostly considered the rock of the highest peak, sitting atop the mountain chain, not in itself extending to the sea level.

They must have said “larger than”. I found the same comparison in wikipedia*. “The impactor [meteor or comet] was around 10 kilometers (6.2 miles) in diameter—large enough that, if set at sea level, it would have reached taller than Mount Everest”. Everest is 8.8 kilometers and the asteroid is 10 kilometers. Even when considering it from the sea to the top, the meteorite is a little bit longer. But I guess length doesn’t mean much for objects that aren’t big enough to become spherical.
