  Nonlinear gravitational condensation theory and quasar-microlensing
observations lead to the conclusion that the baryonic mass of most galaxies is
dominated by dense clumps of hydrogenous planetoids. Star microlensing
collaborations fail to detect planetoids as the dominant dark matter component
of the Galaxy halo by an unjustified uniform-number-density assumption that
underestimates the average value. From (Jeans's 1902) linear gravitational
condensation theory, and from nonlinear theory for different reasons,
proto-globular-cluster (PGC) mass gas blobs should form soon after the plasma
epoch ends and neutral gas appears, about 300,000 years after the Big Bang.
Such PGC blobs should then fragment into planetary-mass objects at viscous and
turbulent Schwarz scales of the weakly turbulent primordial gas, from Gibson's
1996 nonlinear theory. Schild's 1996 interpretation, from measured twinkling
frequencies of the lensed quasar Q0957+561 A,B (after subtraction of the phased
images), was that the mass of the lens galaxy is dominated by "rogue planets
>... likely to be the missing mass". Schild's findings of a 1.1 year image time
delay, with dominant planetoid image-twinkling-period, are confirmed herein by
three observatories.
