"Where you're closer to the center of the earth the gravity is less."

Nope. You weigh less as you are further from the center of the Earth. Think: scuba divers, mountain climbers, pilots, astronauts, etc.

Sorry, Southack, you are wrong. You have succumbed to the oversimplification model (assuming gravitational attraction as a point source at the center of the earth).

At the center of the earth, your weight would be zero. Here is why: The mass of the earth would all be "above" you in all directions and therefore the vector sum of all the gravitational attractions would be zero. It is the gravitational attraction that causes weight.

If you assume only two bodies in the equation (the earth and you), your weight would be zero at the center of the earth. It would increase as you approached the surface of the earth. And then it would decrease as you moved away from the earth.

You also weigh less the closer you are to the Equator. By at least 1-2%. (Factual study and result.)
