Abstract

Indication from the Supernovae Ia Data of a Stationary Background Universe

With redshift parameters independent of time and a constant universal speed of light the simplest cosmological solution of General Relativity stands out from all others. It requires a 'dark' pressure of -1/3 the critical density. This stationary model (anything but static, though) may describe the background universe on ultra-large scales, embedding our evolutionary cosmos therein. Yet it turns out to represent the SNe-Ia data of Riess et al. (2004/2007) surprisingly well. Only in the low redshift range 0.01 < z < 0.1 its luminosity predictions differ from those of today's Concordance Model significantly. - This talk will show how, instead of acceleration, a local Hubble contrast of about 7 ± 2 % within z < 0.025 as reported by Jha, Riess, Kirshner (2007) would result in reasonable agreement with the low redshift data, too.

Relativistic Deduction of a Stationary Tohu-va-Bohu Background Cosmology

Given there has been something where the big-bang origin of our evolutionary 'local' cosmos took place: What is the relativistic line element describing the energy density and pressure of such a pre-existing universal background ('tohu va bohu')? - Two simple postulates are used to deduce the one and only stationary solution of general relativity implying a constant universal speed of light as well as redshift parameters independent of time. It is shown that its gravitational 'dark' pressure, corresponding to a stationarily changing cosmological constant, must be negative. There is a struggle of local SRT (representing quantum mechanics) and universal GRT (representing gravitation). In particular, intrinsic limitations of proper length and time are derived, which would cause a stationary background universe to be chaotic.
