The black holes in the paper are rather speculative entities, remnants
from the big bang. During the initial fireball some regions might have
been compressed into lots of very small black holes which remain to
this day. This paper assumes there is a lower mass for black holes due
to quantization and explores what charged quantum black holes could
do.

Electromagnetism. The electrons or protons are bound by the charge of
the hole. They are not "eaten" (or rather, the rate of falling into
the hole is very low according to the paper).

It is the local, swedish-speaking transhumanist list.
