This is to announce the publication of 'Curvature Cosmology'
by David F. Crawford (BrownWalkerPress: Boca Ratan, Florida.
http://www.brownwalker.com/book.php?method=ISBN&book=1599424134
It is available either as a printed book for $US19.95 (+ postage)
or as a downloadable PDF file for $US12.00.
It is also available from Amazon or Barnes & Noble.

Curvature Cosmology describes a new cosmological theory that
is an alternative to the current Big-Bang cosmology.
It rests on two hypotheses: curvature-redshift and
curvature-pressure and is fully compatible with
General Relativity and quantum mechanics.

It makes predictions for the temperature of the background
X-ray radiation and the cosmic background radiation that
agree with observations. The model shows that the Hubble
constant is a simple function of the density with good
agreement with current results.

The other major observations analysed within curvature-cosmology
are: the background microwave radiation, type 1a supernovae
(it explains the apparent time dilation of the light curves),
time dilation of quasar variability, the linear size of radio
sources, surface brightness of early type galaxies, clusters of
galaxies and the Lyman alpha forest.

Both galaxies and quasars are shown to have a simple Gaussian
density distribution with no evidence of evolution.
It also is shown that a static model for the radio-source-count
distribution provides a good fit to the observations.

Finally it is shown that the deficiency in the observed rates
of solar neutrinos can be explained with a standard solar model
and that the anomalous acceleration of Pioneer 10 arises from
curvature-redshift in the interplanetary dust.

This theory is a static stable cosmology that obeys the perfect
cosmological principle. In addition it is easily refutable and
does not need dark matter, inflation or other ad hoc premises to
have excellent agreement with observations.
