We review properties of theories for the variation of the gravitation and fine structure 'constants'. We highlight some general features of the cosmological models that exist in these theories with reference to recent quasar data that are consistent with time-variation in the fine structure 'constant' since a redshift of 3.5. The behaviour of a simple class of varying-alpha cosmologies is outlined in the light of all the observational constraints.

SciAsto.Net is a network of amateur astronomers in love with the SCIence of ASTROnomy. Our roots go back to the mid 1990s and the astronomy newsgroup sci.astro (still in existance). A few active members decided to start an IRC chat group on the undernet server. Spearheading that effort was Chris Sheehan, Bob Hale
