The
black holes that we can observe directly through their radiant emission are mostly
in a configuration where gas swirls around the
black hole in the form
of an accretion disk and that accretion disk — most
of the mass is going to be
in an ionized form, and then some
of that gas gets expelled from the environment around the
black hole, while it is still outside the
black hole, it gets squirted
out in the form
of an outflow, a wind like the solar wind and then [a] much faster, collimated outflow called a jet.
Normally, these pairs rapidly annihilate and disappear again, but if a pair

black hole.
