Universe with no big bang, no beginning, and no end

“Basically, as the universe expands, time is converted into space, and mass is converted into length. As the universe contracts, the opposite occurs”
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:
• The speed of light and the gravitational “constant” are not constant, but vary with the evolution of the universe.
• Time has no beginning and no end; i.e., there is neither a big bang nor a big crunch singularity.
• The spatial section of the universe is a 3-sphere [a higher-dimensional analogue of a sphere], ruling out the possibility of a flat or hyperboloid geometry.
• The universe experiences phases of both acceleration and deceleration.
(A most fascinating theory. When it says ‘mass converts to length’ it makes me think of 2 dimensions being expanded into 3 dimensions. And Time is the 4th dimension. The 2D flat design precedes the manifestation into 3D space. – JWD) – Full Article Source
