ABSTRACT: A possible alternative to the accelerating
universe is proposed, which shows that the diminished brightness of the high
red shift Type Ia supernovae can be explained by assuming light travels with
reduced speed through the dark energy of intergalactic space. It is also shown that support for themodel from baryon
acoustic oscillations (BAO) studies can also be accommodated by the model. Two
tables are given that compare the model with apparent magnitude differences and
length differences between theuniverse and the
Einstein-de Sitter universe, and they show that the model yields these
differences quite accurately. A third table comparing the apparent magnitude difference
betweenand a universe with is also given. It
exhibits poor agreement with the model, and hence the model favors the need for
dark energy, albeit without negative pressure. As a new approach to the “why
now?” problem, and its apparent challenge to the Copernican principle, it is
proposed that dark energy is a condensed form of dark matter caused by
expansion cooling, rather than a different substance. A motivation for an
alternative tois presented based on
a principle that rules out the cosmological term.
