Interesting thought exercise. I read that Earth's gravity is strongest about its rotational axis, meaning that gravity is stronger at the poles than the equator. Gravity is a phenomenon solely associated with mass, and unlike electromagnetism, it seems to be unidirectional, but that doesn't explain centrifugal force. If you punched a hole through a rotating ball, in a vacuum, and allowed an object to pass through the hole, how would that object react?

Look at his equation again, distance is a factor along with mass. Gravity is a little higher at the poles than the equator because they are just a little closer to the center of the earth.

Also, gravity goes out in all directions just like magnetism.
