from the Author's Notes: Writing these four articles taught me two main lessons: First, the value of a good editor - who can take something you thought was perfect, cut 30% of it out, and produce something that is better than your original piece. And second, how the same ideas are taken more seriously as they move from hand-written notes to typescript to published article. *** Some time after the series was published, it was updated and reprinted in The Best of White Dwarf Articles. In hindsight, this was a mistake, and they should have been reprinted as originally written; so you will not see the updated versions on this website. user summary: This document is an edited and annotated collection of Andy Slack's "Expanding Universe" article series originally published in White Dwarf.
