An empty Kantowski-Sachs universe model with a cosmological constant is found. It emerges from a pancake singularity at t = 0. If the cosmological constant is of the same magnitude as that induced by a GUT vacuum phase transition, this universe enters an exponentially expanding era at the GUT time t/sub G/ = 1,0x10/sup -35/ sec. The universe then isotropizes rapidly, and the shear diminishes by a factor of 10/sup -56/ if this inflationary era lasts for t/sub 1/ = 1,3x10/sup -33/ sec, as is the case in Guth's inflationary universe model.
