5.7 Consider a positively curved universe containing only matter (the "Big Crunch" model discussed in Section 5.4.1). At some time to > terunch 2, during the contraction phase of this universe, an astronomer named Elbbuh Niwde discovers that nearby galaxies have blueshifts (-1 < z < 0) proportional to their distance. He then measures H, and 2o, finding H, < 0 and 2, > 1. Given H, and Qo, how long a time will elapse between Dr. Niwde's observations at t = to and the final Big Crunch att terunch? What is the highest amplitude blueshift that Dr. Niwde is able to observe? What is the lookback time to an object with this blueshift? %3D
