Abstract
Field equations of Wesson’s (Wesson in Mon. Not. R. Astron. Soc. 197:157, 1981) scale invariant theory are obtained, with the aid of a plane symmetric metric in the presence of perfect fluid distribution. Model corresponding to stiff fluid is constructed and discussed. It is found that the model admits a big bang like singularity at initial epoch. Moreover, the shape of the universe remains unchanged during evolution.
