Physics puzzle - say you had a ball 10 cm in diameter. Is there a certain density at which point the ball would plummet through the Earth until it reached the center?

Would the ball be falling, or would it just absorb the earth into itself at that density?
-
That’s the tedious calculation part

But would a 10 cm ball of neutron star material be stable?

I think so? It’s larger ones that collapse into singularities not smaller. There’s probably an evaporation rate or something. Cosmic scale weirdness is far more than we’re used to.
