When Will It All End”?: A Carnegie Mellon Astrophysicists Answer To The Ultimate Fate Of The Universe February 12, 1998 PITTSBURGH–“When will it all end”?
A Carnegie Mellon University astrophysics professor is weighing in on the ultimate fate of the universe, with a new analysis that shows the universe may eventually stop expanding. “Our work does favor a high value for Omega. This has interesting consequences for cosmology, meaning the universe may eventually stop expanding and may even re-collapse. However, people shouldn’t be worried, it will take an infinitely long time to happen,” cosmologist Robert Nichol said. His work puts scientists one step closer to answering the question of how the universe will end. Using new samples of X-ray emitting clusters of galaxies, Nichol and Daniel Reichart, a Ph.D. candidate at the University of Chicago, said they have been able to obtain a measurement that leads them to believe the value of Omega may be one. Omega, one of the two main parameters that explain the evolution of the whole universe – the other is Hubble’s Constant – is the ratio of the observed average density of the universe compared
