Qualms concerning the inflationary scenario

  • B. H. Lavenda

It is shown that the release of the condition of adiabaticity is incompatible with the Einstein equations that are derived from the Robertson-Walker metric. Once dissipative processes are considered, the vanishing of the divergence of the mass-energy tensor is a combination of the first and second laws rather than being the relativistic analogue of the first law. Dissipative processes destroy isotropy and hence cannot be described by any standard model based on Robertson-Walker models.
