Varying Fine-Structure Constant and the Cosmological Constant Problem1
We start with a brief account of the latest analysis of the Oklo phenomenon providing the still most stringent constraint on time-variability of the fine-structure constant α. Comparing this with the recent result from the measurement of distant QSO’s appears to indicate a non-uniform time-dependence, which we argue to be related to another recent finding of the accelerating universe. This view...
متن کاملPossible Cosmological Implications of a Time Varying Fine Structure Constant
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 “cons...
متن کاملImplications 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...
متن کاملTime-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...
متن کاملSimple Model with Time-varying Fine Structure “constant”-part Ii
The extension of Dirac’s LNH to cover cosmological and fine-structure timevarying “constants”, and the rotation of the universe, is here analysed, including a “derivation” of the angular speed of the present universe, and of the inflationary phase. Controversial points in the present calculation are clarified.
