The Future of The Expanding Cosmos is the twenty-third instalment in the Little Blue Book Series and comprises of discourse thirty-nine of the Monodoxy which is itself the first disquisition of the Omnidoxy, the founding treatise of Astronism. This single-discourse publication introduces the discipline of cosmontology known as omnology which deals with all theories, concepts, and beliefs regarding the nature, form, purpose, and eventualities of the expansion of The Cosmos. 
 
The Little Blue Book Series was created and first published by Cometan himself as a way to simplify and commercialise the immensity of the two million word length of the Omnidoxy into smaller, more bite-size publications. A successful series from its very first published entry, the Little Blue Book Series has gone on to become a symbol of Astronist commercial literature and a way for Cometan’s words to reach readers of all ages and abilities who remain daunted by the beauty and yet the sheer extensiveness of the Omnidoxy as the longest religious text in history.
