when i first found out the world was round i thought it would fall and smash on the floor
I used to think that the "speed of light" was the speed of the light going from the switch to the lamp when you turned it on. I was with my parents in a lousy hotel once, and the light in the bathroom would take four or five seconds to turn on since I had pressed the button, so I thought "hey, the speed of light is really low here".
I thought that hot water couldn't put out fires.
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.
When I was little I had a fluorescent bulb in my bedroom. It would often take 1-2 seconds to fully turn on. This was grand because I thought that when people were referring to the speed of light, they mean how long it took a light bulb to turn on starting when the flip was switched. This made me very happy, because I could run to the center of my room before the light came on, and was therefore faster than the speed of light!
When I was younger I asked my dad:
"If I let go of a balloon, would it float up to heaven or space?"
He replied "It'd pop eventually."
I was hugely disappointed, as I'd already let go of a helium balloon that day with my name and address attached to it, hoping that an angel or astronaut would receive it and I'd get some sort of penpal (I wasn't picky).
Incidentally, it ended up a few streets away.
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 really little, probably about 4 or 5 years old, I knew what gravity did (keeps you planted to the ground), but I used to think that the source of gravity was someone named Mr. Gravity, who lived under my parents' bed! I had a mental image of what he looked like and everything... I would also look underneath my parents' bed, trying to search for "Mr. Gravity". My parents never corrected me, probably because they thought it was "cute" or something.
I even thought that under this same bed was a planet of its own... I was a very, umm, imaginitive child!
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
When I was young, I used to occasionally get paranoid that gravity would suddenly start working in reverse. When I thought about this I would always try and make sure that there was a roof over me, just in case, cos I didnt want to fall into space forever.
I used to believe that when i cut my sandwich, i had a slight chance of splitting an atom in the bread, so every time i made a PB&J sandwich i expected to die within a millisecond and everyone within a half of a mile to get they're face melted off. that lasted until i stopped thinking about it, then i learned that the edge of the knife wasn't precise enough to split an atom, so i stopped worrying about it.
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.
i used to belive that the world was spinning because a basketball player was spinning it on his finger and if someone stole it from him the world would forever be in a night or day
When I was in grade school I was convinced by another student that you could make a laser by placing a flashlight inside a drinking glass and angling it just the right way. I tried this at home and was delighted when I saw some light rays come out of the glass at weird angles. I thought for sure I had made my own homemade laser beam!
My older brother told me when I was 3 or 4 that the reason ships float is because they are so light. In fact, they are so light I could lift an ocean liner with my little finger. I figured out the truth by the time I became an adult.
