Discussion of the constancy, or otherwise, of the various so-called universalconstants which abound in physics has continued for many years. However,relatively recent observations, which appear to indicate a variation in thevalue of the fine structure constant, have reignited the subject. Theseobservations relate to quasars and that in itself raises questions. Also, sincemany of the arguments utilise the Bekenstein-Hawking expression for the entropyof a black hole, further controversy is introduced into the discussionimmediately. In what follows these two points will be examined and some lesswell-known theoretical considerations introduced which, hopefully, willinstigate wider examination of this topic.
