Model describes universe with no big bang, no beginning, and no end...

How's about the big bang or the lack thereof for a start!

Lisa Zyga @ PhysOrg.com points out an interesting idea,

By suggesting that mass, time, and length can be converted into one another as the universe evolves, Wun-Yi Shu has proposed a new class of cosmological models that may fit observations of the universe better than the current big bang model. What this means specifically is that the new models might explain the increasing acceleration of the universe without relying on a cosmological constant such as dark energy, as well as solve or eliminate other cosmological dilemmas such as the flatness problem and the horizon problem.
