Question

Why doesn't gravity pull us down to the center of the earth?

Answer 1

Every object attract each other and this is a natural phenomena.

This phenomenon is called gravity.

When two large objects are near in space, they
will attract and possibly collide, and may form a larger object.

There are forces which repulsive in nature like repulsion of similar charges or intermolecular forces .

So in a planet or any big celestial body, these forces maintain the shape of the object and does not allow the mass to collapse in a singularity.

So we are attracted to the centre of mass of earth
