What If We Dug a Hole All the Way Through Earth?

Imagine you dig a big, empty hole straight down to the other side of Earth. If you jumped in, gravity would pull you toward the center, and then push you out on the far side, like a fun ride! But it wouldn’t stop there; you’d keep going back and forth like a swing, unless something stopped you or you went through the air instead of empty space.

Gravity pulls things toward Earth’s center. So when you jump into the hole, it would pull you all the way to the middle, then push you out on the other side, just like a bungee cord! You’d go up and down forever unless something stopped you.
