Decelerated expansion or Future time comes to a halt

Abstract: A new speculative model for the expansion of our universe has been under development by the author for the last two decades, which correctly predicts astronomical measurements with no dark matter or dark energy. This new closed model (no free parameters) correctly predicts that time increases without limit into the future. By contrast, a seldom mentioned future-problem in relativity theory is shown in this paper. Any acceleration of the expansion rate of our universe destroys the proper behavior of time into the future. The goal of this paper is to present this problem of relativity theory and remind the reader of the success of the new model Key words: cosmology: theory; cosmology: cosmological parameters; time: general relativity:
