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.

Shu, an associate professor at National Tsing Hua University in Taiwan, explains in a study posted at arXiv.org that the new models emerge from a new perspective of some of the most basic entities: time, space, mass, and length. In his proposal, time and space can be converted into one another, with a varying speed of light as the conversion factor. Mass and length are also interchangeable, with the conversion factor depending on both a varying gravitational “constant” and a varying speed of light (G/c2). Basically, as the universe expands, time is converted into space, and mass is converted into length. As the universe contracts, the opposite occurs.

“We view the speed of light as simply a conversion factor between time and space in spacetime,” Shu writes. “It is simply one of the properties of the spacetime geometry. Since the universe is expanding, we speculate that the conversion factor somehow varies in accordance with the evolution of the universe, hence the speed of light varies with cosmic time.”

As Shu writes in his paper, the newly proposed models have four distinguishing features:

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

I believe that any true explanation can be reduced to a provable simple logic . Or a simple mathematical formula like E=MC² . I think the ,gravity , black matter ,space/time etc.. will eventually be shown to be a fairly simple logical equation . A lot of these theories will eventually be forgotten and replaced by something more logical and provable .Everything seems to keep coming back to Time/Space as the key to everything . Somehow the unifier of everything . Matter , gravity etc. being just a distortion of Time/Space . Therefore energy is also just a distortion of Time/Space .Seems there’s a simple unification formula lurking there ;-)At least that’s my theory and I’m sticking to it ;-)
