Scenario D — Kardashev II Without a Black Hole . OCSFour chained tools compare the stellar Dyson path to Kardashev II against the IMBH Blandford, Znajek alternative in ω Cen: swarm power budget, compute substrate, IMBH evidence weight, and ergosphere output.
Scenario X — LISA's Shot . OCSThe gravitational-wave and multi-messenger detection roadmap for ω Cen's IMBH: LISA EMRI detectability, astrometric microlensing, synthetic stellar kinematics, and multi-messenger coincidence.
Scenario R — The Matrioshka Option . OCSWhat would a civilization do with a spinning intermediate-mass black hole in a dense stellar cluster? Four chained tools from BZ power extraction to reversible computing show the full stack.
Scenario - Migrate or StayThree chained tools walk Paper D's migration-economics argument: the closed-form patience threshold that decides migrate-versus-densify, the gamma-discounting correction for uncertainty about one's own discount rate, and the concrete engine comparison that decides whether a lineage should act.
Scenario — What the Silence Means · OCSFour chained tools read sixty years of SETI null results as data: the VLA survey power limits, Civiletti's geometrical detection framework, the Drake Monte Carlo prior on N, and the Great Filter interpretation.
Why ωCen and Not the Galactic Centre? — OCSFour tools compare OC's IMBH candidate against the Galactic Centre's Sgr A*, showing why the ergosphere engineering case favours OC. FAQ E.3.
Scenario - Paper E FeasibilityFour chained tools walk Paper E's argument in order: a Monte Carlo envelope sweep against stellar flybys, a single-point drill-down at a chosen radius, the Bondi-vs-waste-heat fuel ordering, and the Bayes-factor adjudication that closes Paper E's argument against real data.
Scenario - From Proposals to NumbersFive chained tools walk through each active OCS observational proposal, showing detection threshold, parameter sensitivity, and timeline for LISA, MeerKAT, JWST, LIGO O4/O5, and the constraint stacker.
Scenario - Reconnection vs. BZ: Which Channel Wins?Three chained tools trace the two parallel energy extraction channels from OC's Kerr IMBH and show when plasmoid reconnection overtakes the Blandford-Znajek jet.
Scenario S — Could We Send a Message? . OCSIf there were a technological civilization in ωCen, could we communicate with it? Five chained tools from Drake equation to neutrino SETI explore every plausible communication channel across 17,900 light-years.
Scenario - Spin-Up Economics: Is Phase 1 Viable?Four chained tools tracing the Phase 1 MTH engineering timeline from stellar capture rate to BZ power output, quantifying the spin-up bottleneck.
Scenario U — Spin Up and Tap . OCSThe complete energy-extraction chain from a Kerr black hole: Penrose process efficiency, superradiance instability, Blandford-Znajek power output, and Kerr ergosphere geometry.
Scenario C — What Happens When a Star Falls In . OCSSix chained tools follow a star falling into ω Cen's IMBH: cluster context, inbound orbit, tidal disruption threshold, Kerr geometry, time dilation, and Bekenstein information limits.
Scenario G — Wait, Compute, Win? . OCSDoes aestivation explain the Fermi silence? Drake Monte Carlo sets the prior on N; the Aestivation Calculator shows the thermodynamic gain from waiting; Bekenstein-Landauer-Lloyd maps the ops budget; Hawking Evaporation confirms the waiting timescale is otherwise irrelevant.
