Abstract
The exact general solution to the Einstein equations is a homogeneous Universe with a full causal viscous fluid source for the bulk viscosit y index m = 1/2 is found. We have investigated the asymptotic stabilit y of Friedmann and de Sitter solutions, the former is stable for m gre ater than or equal to 1/2 and the latter for m less than or equal to 1 /2. The comparison with results of the truncated theory is made. For m = 1/2, it was found that families of solutions with extrema no longer remain in the full case and they are replaced by asymptotically Minko wski evolutions. These solutions are monotonic.
