After the Intake, every resident of New Tripoli wakes inside a deep catalogue of sims — worlds to live in, at whatever speed they choose. This is that catalogue, made browsable, paired with instruments that let you operate the real ideas underneath: how much life a dilation rate actually buys you, why the Universal Sabbath matters, what the world would cost to build.
Each instrument is a single self-contained page — adjust the inputs, watch the canon numbers move, share the URL with your settings baked in.
Pick a dilation rate — from the 50× New Tripoli ceiling to New Andromeda's billion-fold — and see the subjective life you live per real second, the gap between Universal Sabbaths, and how fast you blow past every human limit on the people you can know.
Open instrument →Could you actually run 8 billion preserved brains off the Sahara? The 90/10 substrate split, the power budget, and the surprise: energy is the easy part — biology is the real ceiling.
Open instrument →Click down through the nested reality of New Tripoli — Earth Prime → the cavern → the holodeck residence → the dedicated Sim Room — and see exactly how many layers deep from the physical world a resident is sitting.
Open instrument →An explorable node map of the portal chain — California → Azure Janus → Rust-Mars → Novo Alexandria — with the traversal rules, the hangar mystery, and the black-hole-powered library at the end of the line.
Open instrument →Could the residential ring actually hold 8.1 billion? Slide its width and watch — the famous skyline houses almost nobody; the mid-rise ring does all the work.
Open instrument →Toggle the skeleton material and watch the consequences: an osmium build hits ~450 lb — you can't swim, can't ride a bicycle, and can't be repaired in the field.
Open instrument →Love measured in the enclave's hardest currency. When a faster friend slows down to stay with you, see exactly how many subjective years they give up — the 1,500-year number.
Open instrument →How the Intake arrives: a mass-driver fling across light-years. Set the launch, watch the travel time and impact energy, choose which worlds survive, and pick the ETI's branch.
Open instrument →From garage tools to a femtoscale assembler — a buildable 31-node dependency graph of the post-Wake reindustrialization. You can't skip a rung.
Open instrument →Drexler's dream of a machine that builds matter — and itself — atom by atom. The vision, Smalley's objections, the real 2025 state of the art, and an honest "how far?". Companion to the Tech-Tree's endpoint.
Open instrument →Put two residents on different speed tiers and watch a conversation degrade from real-time chat to letters — and why the Universal Sabbath is the only time it closes.
Open instrument →If the ETI could only keep some of humanity, who makes the cut? Pick a criterion, watch who's deleted — and notice it always, conveniently, spares you.
Open instrument →The real machine in the Libyan desert: an 800-million fridge core inside a 7.2-billion laptop ring. The 90/10 split isn't a statistic — it's physical geography you can never perceive.
Open instrument →The planet eight billion synthetic humans wake to: continent-sized solar arrays, 200+ waystations, sealed fabs, rewilded cities, CO₂ back to 1990. Preserved despite us, not for us.
Open instrument →Zoom out from your apartment to a cube the size of a continent and watch home shrink to a rounding error — residential space is 0.000042% of the volume.
Open instrument →A well-equipped lab, an anomaly to explain, no instructions. Four instances — three solvable, one TAC would rather not discuss; the last hides six absorption features whose spacing converges on φ.
Open instrument →Build the instruments, work the data, argue what it means. 42 objects in the field; one produced a finding the ETI called "unexpectedly sophisticated" — and no one was told which.
Open instrument →The real science behind the "fridge-container": why cryonics works in principle, why no one has ever been revived, and how Alcor's dewars compare to the HSS.
Open instrument →How fast can a preserved mind subjectively run? Not as fast as the datacenter — the brain brings its own rate limits. See the ceiling by augmentation stage, the alpha, thermal, and synaptic floors that set it, and the subjective time it buys.
Open instrument →Today's best implants sample about a thousand channels; the brain has about 86 billion neurons. Slide the channel count and watch the gap, the doublings it would take to close, and why writing to cortex is the harder half of the problem.
Open instrument →Every instrument here is deterministic. This tool anchors that with a real SHA-256 execution hash over a sim's inputs and the canon it cites — same inputs, same hash; change one and it changes. The OpenChainGraph model in miniature.
Open instrument →Each walkthrough sequences the instruments above into a single argument — every step deep-links into a live tool with its inputs preset. Not cutscenes; reasoning you operate.
Energy → biology → augmentation → time → the question. San Junipero is on humanity's own tech tree — so what exactly are we waiting for?
Start the walkthrough →Four checks — energy, housing, the body, the supply chain. Run each one and watch the scenario turn from science fiction into an unbuilt program.
Start the walkthrough →From a thrown probe to a black-hole library: the case that a mature intelligence doesn't conquer — it samples cognitive diversity and keeps it.
Start the walkthrough →Dilation is sold as freedom — but you don't live alone. How running fast turns conversation into letters and closeness into sacrifice.
Start the walkthrough →The headline entries from the resident catalogue the novels tour (§17). These are narrative descriptions of in-world experiences — the texture of the place, not playable builds.
All four canonical islands connected by the films' own transport. The tone is deliberately wrong-footed: no catastrophe, just small mysteries and interpersonal drama inside a functioning park. So popular the ETI later added the real islands to the airport map.
The "007 Floating Lair" — a conical-frustum seasteading megastructure, 26 inches of Yamato-plating, torpedo tubes loaded with robotic sharks. Every floor wider than the one above. Drops you in Fortnite-style and dares you to find a way inside.
A volcanic island surfaces off Ecuador; a family builds a sovereign nation from 5,000 tonnes of reclaimed ocean garbage and a half-installed molecular assembler. Nation-building, pirate repulsion, or Bond-villain aesthetic — your pick of mod.
Learn to ride, read terrain, and hold a town against bandits in a period-accurate frontier — or the Pride, Prejudice & Zombies-styled undead variant. Quietly the first deposit in the series-spanning tech-tree arc: metallurgy you don't yet know you'll need.
Marooned alone with a wrecked ship and a planet's raw materials — the isolated-individual counterpart to The Last City's collective rebuild. Same tech-tree logic, entirely different solitude: every tool you need, you make from what you can find.
The most philosophically weighted sim in the catalogue: a portal chain that ends not at a battle but at a black-hole-powered library with no closing time, extending a standing open enrollment. Late in the series, characters argue it was the ETI's honest advertisement all along.
Interactive scenario pages outside the New Tripoli canon — alt-history divergences and companion CH-catalogue mechanics. Client-side only, no execution hash, adjustable-assumptions panels throughout.
Where the 1918 prisoners of the Central Powers actually went: captor fan-out, the repatriation drain curve, and the labor-vs-parole mortality gap.
Open explainer →A confidence-fading fork tree from a single 1850s point of divergence — four toggles, a speculation horizon, and a 20M–75M real-toll band at hop zero.
Open explainer →Four crisis-standards-of-care policies, one seeded 1,000-patient lottery: lives, life-years, and the equity gap each policy actually produces.
Open explainer →Live Euler-solved SIR curve — slide R₀ and intervention strength, watch the R_eff threshold flip and the herd-immunity marker move.
Open explainer →A 12-task critical-path rebuild grid — check off what's in inventory, toggle the salvage shortcut, watch the gold critical path recompute live.
Open explainer →The prose the instruments draw on — world bibles, canon, and the in-world scenarios. This section is generated from the corpus manifest, so it stays in sync as the writing grows.
