New mind-bending model successfully describes the universe with no “Big Bang”, no beginning, and no end
// July 17th, 2013 // Astronomy and Space News
The Big Bang is generally accepted despite its many holes. What scientists cannot account for in the model, they swap in “dark matter” and theorize that this “unknown” constitutes 75% of our universe. Bit hard to swallow for some. Now, a professor at National Tsing Hua University in Taiwan, Wun-Yi Shu, has proposed a new model built from some of the most basic entities: time, space, mass, and length. In this new mind-bending model, time and space can be converted into each other (with the novel varying speed of light as the conversion factor). Mass and length also convert in the same manner (with a varying speed of light and a varying gravitational constant as the factors). Basically, as the universe expands, time is converted into space, and mass is converted into length. As the universe contracts, the opposite occurs.
According to Shu:
“Essentially, this work is a novel theory about how the magnitudes of the three basic physical dimensions, mass, time, and length, are converted into each other, or equivalently, a novel theory about how the geometry of spacetime and the distribution of mass-energy interact. The theory resolves problems in cosmology, such as those of the big bang, dark energy, and flatness, in one fell stroke.”
The new big bang-less theory proposes that the speed of light and the gravitational “constant” are not constant but rather vary as the universe expands and contracts. It also proposes that time has no beginning – and no end – and the universe cycles through phases of acceleration and deceleration. In addition, Shu’s model shows a spatial section of the universe as a “3-sphere” (consisting of a set of points equidistant from a fixed central point in 4-dimensional Euclidean space). And yeah, it’s not flat as the Big Bang theory postulates.
According to phys.org, these new models overcome some of the deficiencies of the Big Bang theory.
“Shu’s models may also account for other problems faced by the standard big bang model. For instance, the flatness problem arises in the big bang model from the observation that a seemingly flat universe such as ours requires finely tuned initial conditions. But because the universe is a 3-sphere in Shu’s models, the flatness problem “disappears automatically.” Similarly, the horizon problem occurs in standard cosmology because it should not be possible for distant places in the universe to share the same physical properties (as they do), since it should require communication faster than the speed of light due to their great distances. However, Shu’s models solve this problem due to their lack of big bang origin and intrinsic acceleration.”
