Inhomogeneous nucleosynthesis in linearly coasting cosmology

Inhomogeneous nucleosynthesis in linearly coasting cosmology

Abstract We investigate primordial nucleosynthesis in a universe in which the scale factor evolves linearly with cosmic time and which has an inhomogeneous baryon density. We report that in principle one can close the bounds on dynamic estimates of matter by baryons alone – with no need of any exoti...

Zusammenfassung:Abstract We investigate primordial nucleosynthesis in a universe in which the scale factor evolves linearly with cosmic time and which has an inhomogeneous baryon density. We report that in principle one can close the bounds on dynamic estimates of matter by baryons alone – with no need of any exotic dark matter. We address to some concerns on the overall viability of such an evolution.
