Hollow out the earth? Preposterous! No cavity can persist
in the core of an object big enough to be drawn into the
shape of a sphere under its own gravity.
Tiny black holes that would drill microscopic tunnels
through matter wouldn't go unnoticed. I think they don't
exist. For that matter, I think black holes, in the sense
of gravitational singularities, don't exist either, for
the simple reason that their mass energy, even though huge,
is not infinite.
If a theory predicts a singularity, this merely tells us
the theory is incomplete.
