What Happens If You Fall Through The Center Of The Earth?

If you fall through the center of the Earth, you’d zoom back and forth like a bouncy ball going up and down on a trampoline.

Imagine jumping into a giant tunnel that goes all the way to the middle of the Earth. At first, you'd be pulled down by gravity, just like when you jump off a swing and feel your body fall toward the ground. But as you go deeper, something interesting happens: gravity starts pulling you back up.

At the center of the Earth, there’s no gravity pulling you in one direction, it's balanced all around you! So you'd keep going past the center, and then gravity would pull you back toward the surface. It’s like when you swing on a swing set: you go up high, come down fast, and then swing back again.

If nothing stopped you, you’d keep zooming through that tunnel forever, going from one end of the Earth to the other, and back again, just like a ping-pong ball bouncing in a super bouncy house.
