This may just be the type of question that will get me slapped around, but I will ask it anyway.

Every particle with mass has some form of gravity.

If I am standing at the center of our planet...the gravity of the planet is because of its mass. If all its mass is around me...then would't I be pulled apart at the center?

I am guessing this would mean that I would be weightless at the center. And I would get lighter the closer to the center.
