The big bang theory of the universe holds that we exist amidst the remnants of a single huge explosion that occurred about 15 billion years ago. Absent acceleration, the recession velocity "v" between any two remnants (galaxies) is constant. At any given time, the distance "r" between fragments is proportional to v. This is Hubble's law, v=Hr, where H≈ 65 km/sec/megaparsec. For small velocities, one can use the red shift, Z≈ β. The velocity is v=β c. At larger velocities, Z >β and requires SR correction. A second problem is that the measured distances refer to different times. These problems are resolved by plotting distance vs. β/(β + 1). If there is no acceleration, this leads to a linear plot. Plotted this way, recent high-Z data by Perlmutter, Riess, and Schmidt exhibits three linear regions. Since the slope of a linear Hubble plot (1/H) measures time since the big bang, big bangs occurred at 15, 48, and 146 billion years ago. The question, whether the universe is open or closed, is moot since we observe galaxies older than 15*10^9 years. Ref. Lanl physics/0101033.
