Time-Varying Fine-Structure Constant Requires Cosmological Constant

arXiv:astro-ph/9908356 · doi:10.1142/S021773239900198X

Abstract

Webb et al. presented preliminary evidence for a time-varying fine-structure constant. We show Teller's formula for this variation to be ruled out within the Einstein-de Sitter universe, however, it is compatible with cosmologies which require a large cosmological constant.
