Incandescence novel

"**Incandescence**," a 2008 science fiction novel by Australian author Greg Egan, explores the idea that a pre-industrial civilization could discover the theory of general relativity. The book features two interwoven narratives: one follows citizens of the Amalgam, a Milky Way-spanning civilization, investigating DNA found on a meteor near the galactic core controlled by the Aloof; the other centers on the Splinter, a small world orbiting a collapsed star, where inhabitants attempt to understand their precarious environment. The stories converge in a complex twist involving first contact and role reversal.

The novel delves into orbital dynamics around massive objects, requiring knowledge of Newtonian gravitation and general relativity to fully grasp its narrative. It also introduces the Amalgam, a recurring setting in Egan's work, which is further explored in three short stories: "Riding the Crocodile," "Glory," and "Hot Rock."

Critics have varied in their reception: some found it overly technical and dry, while others noted hints of greatness but criticized its structure. British writer Adam Roberts harshly reviewed the book for awkward prose and weak characterization, prompting Egan to defend his work, accusing Roberts of bias and poor review practice.

The Splinter's directional terms are derived from Arabic and Persian words, reflecting cultural influences on its world-building. Overall, "Incandescence" combines scientific concepts with narrative complexity, though its execution has drawn mixed reviews for its technical focus and literary approach.
