lattice-intelligences. They have evolved out of self-directed necessity. To
drink more energy they have learned to dissolve.

As torrents of hard radiation lance through them, they are plasmas. This gathers
in fluxes and stores them in long-range correlations.

When the flood ebbs the phase creatures change. In the cooler spots above the
disk they can condense. Lacy filaments become gaseous discharges. The power so
generated they broadcast outward, to lesser ranks who can store it.

The phase creatures themselves use these fluxes to organize themselves into
free-floating networks. Circuits without wires. Electrons flowing only in their
own self-consistently generated magnetic fields. Voltages and switches
light-quick, gossamer thin.

Lively intelligences dance there. They enter the discussion which has been
teeming above them, in the cooler realms. With silky elegance their thoughts
merge with the hard beings who are the cruder, earlier forms of mechanicals.

But the phase creatures still know their origins. They share the thought
patterns of the metallic forms. They converse.

My reading in evolutionary theory suggested that generally, the rate of
development was faster where the contrast between energy levels was greatest.
This explains why volcanic vents at the bottom of oceans proved a rich life
site. Similarly, the tropics boast of myriad species, the poles few. The
contrast between the black hole region and the surrounding sea of stars is
similarly stark.

I worked out a crude model for setting up a current system which could link the
disk of a black hole to the surroundings. The disk traps magnetic fields as in
falling matter brings the field lines in. A rotating magnetic field can sling
particles -probably electrons and positrons -out along the gradually opening
field lines. The disk acts like an enormous rotating flywheel, driving currents
and mass flow both up and down from the disk. This should yield two jets. One
can calculate the energy yield -- actually, just an upper bound, which turns out
to be considerable.

This part of any electrodynamic model is quite iffy, because we know nothing
directly from the black hole environment. A gamma ray emission was seen several
times through the 1980s from somewhere near galactic center, which corresponds
to the annihilation of electrons and positrons. Perhaps it was from the black
hole region, but certainly it's intermittent, for it vanished years ago and has
not been seen since. Perhaps the weather there changed.

Worse, the calculated energy going into jets proved to be much higher than the
rather weak, broad jet seen (in radio maps) emerging northward from the center.
So perhaps the process is much weaker than we think. Further, there is no
visible counter-jet, casting doubt on the whole assumed geometry of the black
hole region.
