Space-time variation of the fine-structure constant and evolution of isotope abundances
At present several groups are analyzing astrophysical data in a search for the time variation of the finestructure constant a. Here we discuss how to exclude systematic effects caused by changes in the isotope abundances during the evolution of the universe. We suggest using particular combinations of the transition frequencies of O II, Al II, Al III, Si II, and Mn II as anchors, which are inse...
متن کاملTime Evolution of the Fine Structure Constant
We present a short review of the current quasar (QSO) absorption line constraints on possible variation of the fine structure constant, α ≡ e 2 /¯ hc. Particular attention is paid to recent optical Keck/HIRES spectra of 49 absorption systems which indicate a smaller α in the past [1, 2]. Here we present new preliminary results from 128 absorption systems: ∆α/α = (−0.57 ± 0.10) × 10 −5 over the ...
متن کاملFractal Strings as the Basis of Cantorian-fractal Spacetime and the Fine Structure Constant
Beginning with the most general fractal strings/sprays construction recently expounded in the book by Lapidus and Frankenhuysen, it is shown how the complexified extension of El Naschie’s CantorianFractal spacetime model belongs to a very special class of families of fractal strings/sprays whose scaling ratios are given by suitable pinary (pinary, p prime) powers of the Golden Mean. We then pro...
متن کاملFine Structure Anomalies and Search for Variation of the Fine Structure Constant in Laboratory Experiments
Configuration interaction in many-electron atoms may cause anomalies in the fine structure which make the intervals small and very sensitive to variation of the fine structure constant. Repeated precision measurements of these intervals over long period of time can put strong constrain on possible time variation of the fine structure constant. We consider the 5p 3P2,1,0 fine structure multiplet...
متن کاملIndications of a spatial variation of the fine structure constant.
We previously reported Keck telescope observations suggesting a smaller value of the fine structure constant α at high redshift. New Very Large Telescope (VLT) data, probing a different direction in the Universe, shows an inverse evolution; α increases at high redshift. Although the pattern could be due to as yet undetected systematic effects, with the systematics as presently understood the co...
