I am able to post frequently and the subject matters of the posts vary because Poul Anderson's texts are rich, the current text addressing physics, cosmogony, alien biology, hypothetical nonchemical life, technology, society, history and religions both real and projected. Starfarers belongs both to the sub-genre of future history and to the class of works that deal with the concept and implications of time travel.
Still to come in Starfarers are:
Chapter 46, the last Kith installment;
Chapters 47-52, the immediate and ultimate outcomes of Envoy's return to Earth.
After finishing Starfarers, there will be other Poul Anderson works to return to.
