We found 6 concepts from your education that have since evolved or been debunked
What you were taught
"Left-brained people are logical, right-brained people are creative"
What we know now
Brain imaging shows both hemispheres work together for most cognitive functions, and the left/right brain divide is oversimplified.
What you were taught
"Dinosaurs died only from a volcano"
What we know now
While volcanic activity was present, the prevailing scientific consensus is that the extinction of non-avian dinosaurs was primarily caused by the impact of a large asteroid (Chicxulub impactor) about 66 million years ago, which led to widespread environmental devastation.
What you were taught
"The Great Wall of China is visible from space"
What we know now
This popular myth, often taught in schools, is false. While the Great Wall is an immense structure, it is too narrow and blends too well with its surroundings to be visible to the naked eye from Earth orbit or the Moon. Other man-made structures, like major highways or cities, are more easily discernible.
What you were taught
"Reading in dim light ruins your eyesight"
What we know now
The human eye is designed to adapt to different lighting conditions. While reading in dim light can cause temporary eye strain, it does not cause lasting damage to your vision, a fact widely accepted and publicized by the early 2000s.
