Abstract
The theoretical maximum time variation in the electronic charge permitted by the Generalized Second Law of Thermodynamics applied to black holes radiating and accreting in the cosmic microwave background matches the measured cosmological variation in the fine structure constant claimed by Webb et al. Such black holes cannot respond adiabatically to a varying fine structure constant. Copyright © 2012 by World Scientific Publishing Co. Pte. Ltd.
