>>13637803>Gravity increases while nearer on center.Somewhat true but there's a caveat.
The gravitational force decreases like 1/r^2, meaning that as r decreases (the distance between an observer and the center-of-mass of a large body, e.g., the Earth), the force of gravity gets stronger.
However, once the observer's location r is less than the physical radius of the large body (call it R), there's some mass above you that's pulling you in the opposite direction.
In other words, for r>R, the force of gravity F~1/r^2. It turns out that for r<R, the force of gravity goes like r - i.e., it *increases* linearly with distance (you can go through the calculation yourself to convince yourself of this). Thus, when r=0, F=0.
The exception to this is in something like a black hole, in which 100% of the mass is concentrated at r=0. In such a scenario, F->infinity as r->0
