Default Dynamical 3-space resolves the primordial lithium problem


The primordial lithium problem is discribed he

A Bitter Pill: The Primordial Lithium Problem Worsens

Start extract

The lithium problem arises from the significant discrepancy between
the primordial 7Li abundance as predicted by BBN theory and the WMAP
baryon density, and the pre-Galactic lithium abundance inferred from
observations of metal-poor (Population II) stars. This problem has
loomed for the past decade, with a persistent discrepancy of a factor
of 2--3 in 7Li/H. Recent developments have sharpened all aspects of
the Li problem.

The possibility that lithium points to new physics at work in the
early universe thus remains not only viable, but if anything more
likely.

The dynamical 3-space resolution is described he

Dynamical 3-Space Predicts Hotter Early Universe: Resolves CMB-BBN Li7
and He4 Abundance Anomalies

Start extract

The 7 Li problem has been most difficult to understand as its
primordial abundance should be the most reliable, because of the
higher observational statistics and an easier extrapolation to
primordial values.

Various possible resolutions were discussed in [2], with the
conclusion that the lithium problem most likely points
to new physics.

It is shown herein that the new physics of a dynamical 3-space results
in a 20% hotter universe during the radiation dominated epoch, and in
a parameter-free analysis the BBN abundances are brought into close
agreement with the WMAP value for the baryonic density
Omega_Bh^2 = 0.0224 +/-0.0009. The dynamical 3-space
also gives a parameter free account of the supernova redshift data,
and fitting the LambdaCDM to the dynamical 3-space model requires
Omega_Lambda = 0.73 and Omega_m = 0.27, independently of the
supernova data.
