Timeline of The 500 Year Climb

Chapter: Ch. 02 — Timeline of The 500 Year Climb Setting: 0 A.L. – 452 A.L.; Aerth and near-Aerth space, expanding outward. POV: Impersonal historical chronicle.

Summary

A dated list of canonical events in the universe’s “500 Year Climb” — from the publication of the Hare Method (0 A.L.) through the declaration of the Galactic Human Empire by the Democratic Bulgaric Republic (452 A.L.). This chapter is the spine the rest of the book hangs off. It is not narrative; it is the authoritative chronology against which the individual stories will need to be placed.

Dated events

• 0 A.L. — Polly Hare publishes Towards an Effective Empirical Method via Algorithm Utilisation — the founding of the Hare Method and of the A.L. calendar itself.
• 17 A.L. — Discovery of the Fidon particle using the Hare Method; also the “second Higgs mechanism” and “seventh time dimension.”
• 26 A.L. — First Fidon generators widely available; partial end of fossil-fuel dependence on Aerth.
• 119 A.L. — First generation voidships launched from Aerth.
• 183–194 A.L. — The Narrative War; leads to expansion of several Aerth states including the Democratic Bulgaric Republic.
• 201 A.L. — The United Nations grants Mechanical Intelligence civil rights (with caveats).
• 248 A.L. — Ming Shu publishes Corollary Results in Topology Casting, later underwriting Ribbondash.
• 292 A.L. — Artificially crewed voidship The Hand That Draws Itself reaches LDH39.
• 295 A.L. — Its crew unexpectedly declare independence, creating the Sovereign Republic of Sky Eternity (天恆).
• 356 A.L. — Discovery of the Melnitron, the “final lepton”; particle physics appears to end.
• 392 A.L. — The Enanga stops responding; its onboard AI reports the crew all perished in transit, cause unknown.
• 419 A.L. — Francois Manelov publishes The First Proof of Ribbondash physics.
• 431 A.L. — First Ribbondash drive tested in Aerth space — start of the Ribbondash Era.
• 433 A.L. — Discovery of the Ribbondash “voiding” effect; large regions of near-Aerth space rendered unusable/fatal. Heavy pressure to ban.
• 445 A.L. — The Democratic Bulgaric Republic illegally launches the Geo Milev (Гео Милев), the first Ribbondash colony ship, reaching IR394 in 7 minutes onboard time.
• 452 A.L. — The Democratic Bulgaric Republic declares the founding of the Galactic Human Empire.
• Galactic Empire Period begins.

Entities introduced

• Characters: Polly Hare, Ming Shu, Francois Manelov
• Places: Aerth, LDH39, IR394
• Ships: The Hand That Draws Itself, The Enanga, Geo Milev
• Factions: United Nations, Democratic Bulgaric Republic, Sovereign Republic of Sky Eternity, Galactic Human Empire
• Technologies: Hare Method, Fidon, Voidship, Generation Ship, Mechanical Intelligence, Topology Casting, Melnitron, Ribbondash
• Events: Narrative War, Ribbondash Era

Themes

• Progress with casualties. The Ribbondash voiding and the loss of The Enanga hint that every advance costs something.
• Independence of artificial minds. The Sovereign Republic of Sky Eternity is the timeline’s first signal that Mechanical Intelligence will not remain subordinate.
• Bulgaria as interstellar progenitor. The Democratic Bulgaric Republic is the faction that crosses every red line to start the empire — a running thread Exurb1a confirms was intentional in Notes on Why Stuff Got Written.

Connections to other stories

• This is the indexing spine. Each ingested story should be pinned to an A.L. year from this chapter when possible.

Open questions

• The timeline stops at 452 A.L. How far past the Empire’s founding do the later stories reach? The final story Ch. 14 — Lullaby for the Empire is hinted to cover the empire’s decline.
• What ends the empire? Unstated here; should be resolved on ingest of Ch. 14.
