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.”

Именно излученная частицей электроном энергия поля, то бишь фотона, остаётся постоянной и значит и скорость фотона по формуле Е = mС**2
Альфу измеряли, она неизменна, это возможно только если интенсивность взаимодействий зависит от скорости света.
То есть, уменьшается скорость света, и уменьшается скорость электрона на орбите ядра.
Разница энергий двух электронов на разных орбитах остается прежней, то есть длинна излучаемой волны прежняя.

SEOKCHEON LEE. TIME VARIATION OF FINE STRUCTURE CONSTANT AND PROTON-ELECTRON MASS RATIO WITH QUINTESSENCE написал(а):
Recent astrophysical observations of quasar absorption systems indicate that the fine structure constant and the proton-electron mass ratio may have evolved through the history of the universe. Motivated by these observations, we consider the cosmological evolution of a quintessence-like scalar field coupled to gauge fields and matter which leads to effective modifications of the coupling constants and particle masses over time. We show that a class of models where the scalar field potential V() and the couplings to matter B() admit common extremum in naturally explains constraints on variations of both the fine structure constant and the proton-electron mass ratio.

Hao Weilow, Xiao-Peng Maa and Hao-Yu Qi. f(T) Theories and varying fine structure constant написал(а):
In analogy to f(R) theory, recently a new modified gravity theory, namely the so-called f(T) theory, has been proposed to drive the current accelerated expansion without invoking dark energy. In the present work, by extending Bisabrmodifier letter apostrophes idea, we try to constrain f(T) theories with the varying fine structure “constant”, e2/planck constant over two pic. We find that the constraints on f(T) theories from the observational / data are very severe. In fact, they make f(T) theories almost indistinguishable from CDM model.

Although the origin and even the name of the fine structure constant suggest that it is independent of time, this cannot be taken for granted. One of the first suggestions that alpha was time dependent was proposed by string theorists. Many forms of string theory allow for and even require a time dependent fine structure constant. This has led to many experimental searches for this time dependence of the fine structure constant. Before 1999[9] there was no experimental evidence to vindicate the string theorists’ claims. In 1999 John K. Webb found evidence of a time dependent fine structure in the spectra of quasars (Webb et al., 1999, Phys. Rev. Lett. 82, 884).
