Stationary analogs of de Sitter and anti-de Sitter spacetimes: Evidence in favor of $\Lambda$ as a dark fluid

M. Nouri-Zonoz, A. Nouri-Zonoz

We introduce novel Einstein spaces which are the {\it stationary analogs of de Sitter and ani-de Sitter} spacetimes. Having $\Lambda$ as their only parameter, the inherent anisotropy in…
