physics

I thought that deep space was 100% empty of matter, except for the random star, nebula, black hole, or planetary system. Since I always heard that space was a vacuum, I also believed that except for the dust and dirt inside a vacuum bag, I believed that the rest of the "space" in a vacuum bag was totally empty, just like space. I learned otherwise about the vacuum bag pretty early on, but I finally learned that outer space is not completely empty some time in 8th grade Earth Science.

I had an idea at school to dig a tunnel through the centre of the earth and out to the other side. I would then drop things down it and since the object would be moving faster as it passed through the core, gravity should have less effect and it should shoot out of the tube and into space then other side. It could have been used to dispose of nuclear waste or defend Earth from asteroids but it never materialised.

There were train tracks just back of my grandmothers house. I was 5 or 6 and used to try to run too close. My grandmother told me that there was a vaccummm force and if I was too close when it whooshed by the force would suck me under and i would of course die. Hence I stayed away from all train tracks. In highschool science we learned of many different forces but I still beleievd this maybe was cintrifgal or the doppler effect with air ...Ok I didnt listen much in science, until the day i was visiting a friend in my twenties and ran like hell from the tracks becasue a train was coming. When I told them why they laughed themselves silly . I can't believe I still kept this idea for so long.

when i first found out the world was round i thought it would fall and smash on the floor

While in the car, I remember asking my parents : "is it our car that's moving or is it the whole scenery that's somehow moving past us while the car stands still?"

I used to believe that the world was actually flat, and that we were at the bottom of the universe, with the sun and moon, and all the stars floating up above us.

I remember making myself a pair of Icarus wings out of cardbord. I drew wing shapes and cut them out and made arm straps too. I was really convinced that I would be able to run down the street flapping my arms and take off.
Needless to say, I was heartbroken when it didn't work. :(

I use to think that if I laid real still in my bed at night I could feel the earth turn. I would do this all the time. I convinced myself I could feel the earth turn.

When I was a little girl I knew that the earth rotated on it's axis. I thought that the earth made a complete turn every day and that while it was turning everything was upside down ! Since this didn't happen during the day I would try to stay awake all night long hoping to see everything upside down. When I would wake in the morning I'd be very disappointed because I missed it !

i used to think that vacuum cleaners had little piece of space inside them because space is a vacuum

Up until about 14 years old, I never believed that a knife totally cut anything in half. I always thought there was a tiny sliver that got pushed down directly under the blade that was so small it was not visible to the human eye.

I believed when I was little that if you could hover right above the ground that the earth would spin underneath you.

When I was small I thought that when the sun is setting down, it goes right under the ground and comes out on the other side the next day.

My other belief was that in every grade, I had to pass an exam to move on to the next grade.
