Abstract
Description
Discussion of the constancy, or otherwise, of the various so-called universal constants which abound in physics has continued for many years. However, relatively recent observations, which appear to indicate a variation in the value of the fine structure constant, have reignited the subject. These observations relate to quasars and that in itself raises questions. Also, since many of the arguments utilise the Bekenstein-Hawking expression for the entropy of a black hole, further controversy is introduced into the discussion immediately. In what follows these two points will be examined and some less well-known theoretical considerations introduced which, hopefully, will instigate wider examination of this topic.
