Posted 11/29/06 (behind schedule due to transmission error.)
My thanks to Stephen J. Crothers, Tim Eastman and Francesco
Sylos-Labini for sending me papers that I had overlooked and are
included here. All ACG subscribers should feel free to send in
suggestions. Please email the editor at

There are quite a few articles that study the Hubble diagram
for GRBs (gamma-ray bursters) and the questions of whether they
or QSOs may be associated with low redshift galaxies. An earlier
discussion of this topic is by Geoffrey Burbidge, Nucl. Physics
B, 132, 305 (2004.)

Two papers re-analyze well-known data sets with surprising
results
On the Absence of Cosmic Acceleration
Authors: John Middleditch

The Cosmic Background Explorer's time-ordered data is also
consistent with the absence of anisotropies in the cosmic
microwave background

On the topic of CMB, an author argues that two more free
parameters are needed to fit WMAP data
Running of Running of the Spectral Index and WMAP Three-year
data
Authors: Qing-Guo Huang

Another study that confirms that Big Bang simulations are
unable to from the large-scale structure that is observed
Formation of the Supercluster-Void Network

On light element synthesis, new data makes the contradiction
between observation and BBN predictions even sharper

Helium abundances above 35% indicate that all of He abundance
could have been produced by stars
NGC 6441: another indication for a very high helium content in
Globular Cluster stars

This paper is a good survey of the development of the black
hole concept and the theoretical reasons why such objects can
not exist.
A Brief History of Black Holes
Stephen J. Crothers
Progress in Physics B, 132, 305
http://www.geocities.com/theometria/holes.pdf
An attempt to integrate plasma physics and GR, showing how
plasma phenomena can generate high electric fields to accelerate
particles. (Contrary to the statement at the end of this paper,
work on such acceleration dates back to Alfven’s in the 1930’s)
Magnetohydrodynamics and Plasma Cosmology
Authors: K. Kleidis, A. Kuiroukidis, D. B. Papadopoulos, L.
Vlahos
