OK don't believe

was that " I don't believe"?. here is an excerpt from the shell theorem.

A corollary is that inside a solid sphere of constant density, the gravitational force varies

**linearly**with distance from the centre, becoming

**zero**by symmetry at the

**centre**of mass. This can be seen as follows: take a point within such a sphere, at a distance {\displaystyle r}

gravity goes down all the way, can remain constant above extreme dense masses, but will not go up, only down gentler. Reason being that the interior denser mass, like the core, is already a contributor to the total gravity. stripping the layers above it, will not increase the central mass. Only the enclosed mass generates gravity,

gravity goes down, time goes up.

Of course pressure, energy also generates gravity, but it takes a lot of it. still, zero at the center, even in a black hole.

time wihtout formulae.
