The best way to show that it doesn't matter where alot of the weight of a planet is, as
long as it's mostly uniform (and it will be), the combined mass of all the atoms from you,
drawn straight down to the core of the planet, will, roughly, be equivalent.
So, whether the decent amount of mass is in the core, or in the mantle (impossible, the
pressure of the weight would force it to become a core, but still,) the total mass is
still the same and therefore pulling on you the same no matter where the
mass is located in the planet.
