1.These three prejudices led Einstein to introduce the cosmological term to construct a static solution that was finite and yet had no boundaries—his universe curved back on itself like the surface of a balloon [see illustration on page 74].
4.Contrary to the standard big bang space-time singularity,these big bounce singularities are found to be event horizons at which the scale factors and the mass densities of the universe are finite,while the pressures undergo a sudden transition from negative to positive infinities.
