So, if gravity is an effect, why are we not able to shield ourselves from it ?
Say by standing on 10 feet thick lead floor. ? Gravity seems to work not in a direct linear manner. It's influence seems to be relative to the density of the earth beneath (Solid granite vs sand.) or the distance from it.
Are we pushed down, or are we pulled down.
Still does not answer the earth's liquid core being a magnet.
Perhaps I should heed the advice given to Albert !

Gravity (whatever it is) is a affectation of mass. To balance a frce vector one must introduce a force (magnitude and direction) proportionate to the displacement one seeks.
Magnetism is a result of charged alignments of atoms within a volume and is also a function of the direction and magnitude of current (atomic factors which can be ignored, depending on scale). Gravity is a function of mass, regardless of charge.
One could shield a volume of space by exactly replication (and opposite sign) the space-time distortion plus the magnetic force in a sign-opposite direction.
