Non-standard cosmology - History
Since the discovery of the cosmic microwave background by Penzias and Robert Wilson in 1965, most cosmologists have concluded that observations are best explained by the big bang model. However, there have been two periods in which interest in non-standard cosmology has increased due to observational data which posed difficulties for the big bang. The first occurred was the late 1970s when there were a number of unsolved problems such as the horizon problem, the flatness problem, and the lack of magnetic monopoles challenged the big bang model. These issues were eventually resolved by cosmic inflation in the 1980s. This idea subsequently became part of the understanding of the big bang, although alternatives have been proposed from time to time. The second occurred in the mid-1990s when observations of the ages of globular clusters and the primordial helium abundance apparently disagreed with the big bang. However, by the late 1990s, most astronomers had concluded that these observations did not challenge the big bang and additional data from COBE and WMAP provided detailed quantitative measures which were consistent with standard cosmology.
In an Open Letter to the Scientific Community,[1] signed by thirty-three non-standard cosmology supporters, including astronomer Hermann Bondi, and published in the May 22nd 2004 issue of the New Scientist periodical, they protest that the Big Bang theory has not been able to provide a basis for quantitative predictions. They also decry the lack of funding for the support of non-standard research.
In contrast to this, the overwhelming majority of cosmologists, astrophysicists and astronomers consider the Big Bang theory, exemplified by the concordance Lambda-CDM model, hugely successful. Also the 1990s gave a massive improvement to the precision of observational data, which continues to agree with the standard cosmology.

Sneak-Peek of Global Oneness Community
Hi friend! The Global Oneness Community, the place for information and sharing about Oneness is not really launched yet (you will see there is still some clean up to do) ...but it is now open for a sneak-peek! And if you wish - please register and become one of the very first members to do so! Jonas
