چکیده

Webb et al. [2] experimental results on the fine strucutre “constant ” variation with the age of the Universe, is here analized. By using the experimental data on the fine-structure “constant ”’s variation with the age of the Universe, and Dirac’s LNH (Large Number Hypothesis), we find how should vary the total number of nucleons in the Universe, the speed of light, Newton’s gravitational “constant ” and the energy density, and we make an estimate on the deceleration parameter, finding that the Universe would be accelerating, just as Supernovae observations have concluded.

A Varying-α Brane World Cosmology

We study the brane world cosmology in the RS2 model where the electric charge varies with time in the manner described by the varying fine-structure constant theory of Bekenstein. We map such varying electric charge cosmology to the dual variablespeed-of-light cosmology by changing system of units. We comment on cosmological implications for such cosmological models.

Implications of a Time-varying Fine Structure Constant

Much work has been done after the possibility of a fine structure constant being time-varying. It has been taken as an indication of a time-varying speed of light. Here we prove that this is not the case. We prove that the speed of light may or may not vary with time, independently of the fine structure constant being constant or not. Time variations of the speed of light, if present, have to b...

Time-Varying Fine-Structure Constant and Quantum SuperStrings

In this note we observe that Webb and co-workers’ observation of an evolving fine structure constant has since been reconfirmed. We also confirm Kuhne’s contention that this implies a cosmological constant and exhibit a cosmological mechanism for Webb’s result. We also see how this provides a mechanism to reach elementary particle scales from the Quantum Superstring scale. Kuhne[1] suggested so...

A Model of Varying Fine Structure Constant and Varying Speed of Light

The recent evidence for a cosmological evolution of the fine structure constant α = e/h̄c found from an analysis of absorption systems in the spectra of distant quasars, is modelled by a cosmological scenario in which it is assumed that only the speed of light varies. The model fits the spectral line data and can also lead to a solution of the initial value problems in cosmology. e-mail: moffat@...

Inspired by recent claims for a varying fine structure constant, alpha, we investigate the effect of “promoting coupling constants to variables” upon various parameters of the standard model. We first consider a toy model: Proca’s theory of the massive photon. We then explore the electroweak theory with one and two dilaton fields. We find that a varying alpha unavoidably implies varying W and Z...
