Do you know the person who discovered gravity?
The person who found out about gravity was Sir Isaac Newton. He found out when he saw a apple fall from a tree and he was confused because he didn't know what made it fall. He done a experience on gravity which made him curious about it.
Then he notices that gravity pulls you down. Did you know why asteroids fall to earth? I'm gonna tell you why because if a asteroid comes close to earth gravity takes over the force and steals the asteroid from the other dimension which is very weird because who knew that gravity? was that strong maybe thats how the rocket ships fall back down and explode. Have experienced sky diving because gravity pulls you down at the same time your diving down.
