If u really could dig a hole to China, and u did, and u fell in, would u stop in the middle because of gravity?

Assuming that u did dig through the center of the Earth, yes.

You'd melt, and probably evaporate, and heat rises, so.... :S

Plus the magma in the mantle would rise, cool down to a solid, expand, and you'd just land on very hot lava.

There's a center of the Earth?
I thought it was an alien spaceship.

Yeah, u would. I read this awesome book called "Tunnels" in one of the later, they are at of near the center of the Earth and they are weightless. i asked my Dad about it, and he zei that yeah, u really would be weightless because the mass of the Earth is pulling u in every direction.
