Abstract
This paper discusses the role of dissipative processes in the early Universe, in accordance with the ‘chaotic cosmology programme ’ outlined by Misner. The conclusions drawn are that (i) for arbitrary initial conditions the shear anisotropy could be arbitrarily large now, (ii) the Universe need not have been in thermal equilibrium during the early stages, and (iii) matter effects are unimportant in most, but not all, of the cosmological models considered (a new exact solution being given as a counterexample of the general behaviour). These results are valid for a moderately large class of non-rotating spatially-homogeneous cosmologies, and so considerably extend the earlier work of Stewart.
