Put your scientific misconceptions you had in childhood here

I remember thinking that there was a literal crater somewhere in the Yucutan until maybe a few years ago, where I learned that at this point, all that remains is a layer of rock underground. I think I saw a photo online of a CGI recreation or something and 8-year-old me thought it was an actual photo.

And a ring of these water-filled caves around the rim of the crater.

a meteor kills dinosaurs and 66 million years later the mayans use the caves in the cenote ring as a fresh water source and build a civilisation. okay now why did the website moved my post to here when i was trying to edit another post and why canā€™t i delete the ping to multicraft or this post altogether without it saying this post has been deleted by user for 24 hours

This isnā€™t really a scientific misconception butā€¦

You know the joke, why did the chicken cross the road? Why of course to get to the other side. Itā€™s simple logic and not really funny, or at least thatā€™s what I thought untill embarrassingly recently I realized that ā€œthe other sideā€ has implications of a place different from the other side of the road.

I donā€™t think anyone has heard that joke and gotten it on the first time ever since it became so common. Children arenā€™t able to get it, maybe a long time ago adults could experience it for the first time, but by now, by the time an (young) adult can get the joke theyā€™ve heard it a million times.

So as if the chicken crossed the border between life and death?

Not sure if this counts as a scientific misconception but when I was younger I thought that once a tick bit you, it would not detach on itā€™s own and would stay stuck to you permanently unless you removed them manuallyā€¦In hindsight this doesnā€™t make logical sense, if a tick stuck to itā€™s host permanently than how would it reproduce?

I used to think a long time ago that if you dropped a sweet in a car, it would taste like a car (which I imagined to be an extremely bitter taste).

Depends on how much you rub it. And how wet they are.

It was more like I thought that if a sweet touched the car even for a milisecond in the cleanest place, it would still gain this ā€œcarry tasteā€.

I meant as in a ā€œcar tasteā€ not curry, albeit a curry-tasting sweet would too be a strange find.

This isnā€™t exactly a scientific fallacy.
I used to think that the flag of Brazil is the flag of Great Britain
I also used to think that fish breathe due to the fact that the water that enters their mouth through the gills goes back into the ocean, due to which the fish could breathe air in an air pocket

So you believed that fish could breathe air if the said air was in an air pocket?

I used to think that fish could breathe air, but on land they die because they dry out.

And I also thought that dinosaur bones were immune to lava because I found out somewhere that dinosaurs became extinct due to volcanoes and since I didnā€™t know then that the main cause of death from volcanoes is gases and not lava, I then thought that if dinosaur bones are immune to lava lava, after all, they have survived to this day.

And I also thought that all large and dangerous extinct animals are dinosaurs (even if they are arthropods)

I used to think that modern mammals lived back in the time of dinosaurs, but unlike dinosaurs, they did not become extinct

That is a part of the reason for their death on land in many cases, and for the air-breathing fishes, the largest cause most likely. Maybe you heard of these more resiliant fishes without knowing about their ways of acquiring oxygen?

I grew up thinking Deer were vegetarians.

Pretty much no herbivores are ā€œtrue vegetariansā€, and in pretty much every species youā€™ll find cases of consuming other creautres.

I thought that everyone knew the Earth was round and the Earth revolves around the Sun.
