SPACE/EVOLUTION: Physicists fold their hand

Those of you interested in these areas, may be interested in
the following paper: "Death of Stellar Baryonic Dark Matter"
by Katherine Freese, et. al.:

Katherine is one of the leading theoretical physicists
in this area. To quote her conclusions:

1) Nonbaryonic dark matter in our Galaxy seems to be required, and

(I freely grant this point, but suspect if my perspective on
the activities of intelligent technological civilizations turns out
to be true, then this point may need to be reexamined.)

2) The nature of the Machos seen in microlensing experiments and
   interpreted as the dark matter in the Halo of our Galaxy
   *remains a mystery*. Are we driven to primordial black
   holes [25] [26], nonbaryonic Machos (Machismos?), mirror
   matter Machos ([27]) or perhaps a no-Macho Halo?

No, no, it couldn't be, it would be terrible if it were....
(drum role in the background please...): "astroengineering".

It is amazing how some people will accept things that require
huge amounts of imagination in one area, but will not grant
similar flexibility in other areas.

Ah well, such is life.
