Weightlessness at Earth’s Center

If you fell into a hole that goes all the way through the Earth center, accelerating you quickly,

until you reached the exact center of Earth. There, you would experience

a moment of weightlessness as if you were floating in space. You see, on the surface,

earth's mass is entirely below you, which pulls you down. But at the center,

Earth's mass is actually all around you, pulling you in every direction and making

you levitate.
