twin universe cosmology
PREAMBLE TO THE ARTICLE PUBLISHED IN 1995 IN THE JOURNAL
ASTROPHYSICS AND SPACE SCIENCE, TITLED:
TWIN UNIVERSE COSMOLOGY
...This article is a draft of the "variable constants model", which will be taken up in article 6, titled: Matter ghost-matter astrophysics.3: The radiative era: The problem of the "origin" of the universe. The problem of the homogeneity of the early universe. The geometric scheme of paper 1 is continued in the following article (section 1). Numerical simulations performed by F. Landsheat provide an initial interpretation (2d) of the Very Large Structure. The theme of the negative gravitational lensing effect is present (section 4), as well as that of the justification of the homogeneity of the early universe (section 10). In section 11 it is shown that the evolution of such a universe is non-isentropic, the entropy per baryon being then proposed as a new chronological marker (section 12), which leads to the disappearance of the initial singularity (figure 19) and the fact that the metric then becomes "conformally flat" (equation 93).
