  Small values of lithium observed in a small, primitive, Galaxy-Halo star SDSS
J102915 + 172927 cannot be explained using the standard cold dark matter CDM
theory of star formation, but are easily understood using the Gibson/Schild
1996 hydrogravitationaldynamics (HGD) theory. From HGD, primordial H-4He gas
fragments into Earth-mass planets in trillion-planet
proto-globular-star-cluster (PGC) clumps at the 300 Kyr time of transition from
the plasma epoch, soon after the big bang. The first HGD stars formed from
pristine, frictionally-merging, gas-planets within the gently stressed clumps
of the early universe, burning most available lithium in brown-dwarfs and
hot-stars before creating metals that permit cooler burning. The Caffau halo
star is a present day example. CDM first stars (Population III) were massive
and promptly exploded, reionizing the gas of the universe and seeding it with
metals, thus making the observed star unexplainable. From HGD, CDM and its
massive first stars, and re-ionization by Pop III supernovae, never happened.
All stars are formed from planets in primordial clumps. HGD first stars (Pop
III) were small and long-lived, and the largest ones were hot. We suggest such
small HGD (Pop III) stars still form in the gently stressed Galaxy halo.
