Query: Quasar-microlensing versus star-microlensing evidence of
  small-planetary-mass objects as the dominant inner-halo galactic dark matter   We examine recent results of two kinds of microlensing experiments intended
to detect galactic dark matter objects, and we suggest that the lack of short
period star-microlensing events observed for stars near the Galaxy does not
preclude either the ``rogue planets'' identified from quasar-microlensing by
Schild 1996 as the missing-mass of a lens galaxy, or the clumps of such objects
predicted by the new Gibson 1996-2000 hydro-gravitational theory as the
inner-halo galactic dark matter. We point out that such micro-brown-dwarfs in
nonlinear accretional cascades to form stars give intermittent lognormal number
density n_p distributions. Hence, star-microlensing searches that focus on a
small fraction of the sky and assume a uniform distribution for n_p are subject
to undersampling errors. Sparse independent samples give modes smaller than
means of the highly skewed lognormal distributions expected.
Quasar-microlensing searches with higher optical depths are less affected by
intermittency. We attempt to reconcile the results of the star-microlensing and
quasar-microlensing studies. We conclude that star microlensing searches cannot
exclude and are unlikely to even detect these objects so easily observed by
quasar-microlensing and so robustly predicted by the new theory.
