Solving the horizon problem with a Delayed Big-Bang singularity | | Marie-Noëlle Célérier
; | | Date: |
19 Nov 1999 | | Subject: | gr-qc astro-ph | | Affiliation: | Observatoire de Paris-Meudon | | Abstract: | The hot Big-Bang standard model for the evolution of the universe, despite strong successes, lets unresolved a number of problems. One of its main drawbacks, known as the horizon problem, was until now thought to be only solvable by an inflationary scenario. Here is proposed a class of inhomogeneous models of universe, getting rid of some of the worst drawbacks of standard cosmology. The horizon problem is solved by means of an initial singularity of ``delayed’’ type and without need for any inflationary phase. The flatness and cosmological constant problems disappear. | | Source: | arXiv, gr-qc/9911072 | | Services: | Forum | Review | PDF | Favorites | |
