The Milky Way program
brief strategy

1. The goal and its hierarchy

Long-term reference point: an interstellar ship by 2201. This is not a forecast and not a promise of a launch date. The goal sets the scale of the task and lets us plan from the required result back to today's actions. Transitions between stages are set by the readiness of science, engineering, economics, and the institution, not by a single date.

The primary goal is not the ship itself, but overcoming limits: developing the knowledge, technologies, and institutions capable of working on problems that outlast a single human lifetime. If fast modes of travel prove physically impossible, the program still has meaning. Its results remain fundamental discoveries, applied technologies, a durable scientific organization, and sub-light missions.

Four independent outcomes of the program:

• Knowledge — testable science of gravity and the dark sector (dark matter and dark energy), independent of the destination.
• Benefits for Earth — closed life-support systems, new energy sources, autonomous medicine, and the production of food and materials should find applications on Earth long before launch.
• The resilience of life — developing humanity's ability to live beyond a single planet and, in time, beyond a single star system.
• Responsible AI — an interstellar mission creates a strict practical setting for autonomous systems that remain reliable, controllable, and aligned with defined values for decades.

The “Earth first” doctrine — a Charter obligation to seek terrestrial applications for dual-use technologies and to measure the benefit created. In the longer term, some resource-intensive energy and industry can be placed outside the biosphere. Space activity is not a substitute for care of Earth. It is one way to reduce the load on the planet.

2. Method: planning backward from the goal

From the ship of 2201 we build the chain backward: ship ← demonstrators ← engineering theory ← large-scale physics in space ← a scientific and industrial base ← the foundation of the institution ← today. Each link answers the question “what must be ready for the next to become possible.” That is how the seven Eras and the decision gates are obtained.

The plan is kept as a system of dependencies, not as a linear schedule. Every major piece of work has a required prior state, a measurable result, an owner, a budget, a stopping criterion, and an alternative path. Core assumptions are revisited at every gate, and the ship's architecture is not fixed until sufficient data exist.

3. Four workstreams

An interstellar ship is the result of several systems working together. From the start, the program therefore develops in four connected workstreams:

• Fundamental science: gravity, the dark sector, precision measurements, testable hypotheses, and independent replication.
• Engineering and infrastructure: propulsion, energy and power delivery, heat rejection, materials, autonomy, communications and navigation, life support, medicine, and off-world manufacturing.
• Economics: applied products, a company portfolio, an endowment, and space services that gradually lower the cost of research and reduce dependence on donors.
• Institution and society: international hubs, governance and succession, education, specialist training, ethics, law, and public understanding of the program.

No workstream replaces the others. A new principle of propulsion is useless without energy and heat rejection; an engine is useless without autonomy and life support; technologies are useless without the people, the economy, and the institution able to carry them through to a mission.

4. What is known, and what remains unknown

The strategy begins by acknowledging its limits. Today there is no engine, power system, biosystem, or autonomous AI sufficient for a crewed interstellar flight. A speed on the order of 0.1c is a target engineering range for comparing concepts, not a guaranteed result. A controllable spacetime metric and traversable wormholes remain hypotheses. They are not a required condition of the program.

Critical dependencies of the plan:

• growth in available energy and power, with heat rejection solved, predominantly outside the biosphere;
• a lower cost of access to space, and the emergence of servicing, manufacturing, and assembly beyond Earth;
• decades of safe autonomous operation of hardware, medicine, and closed biosystems;
• communications and navigation at interstellar distances, including the return of scientific data;
• international law, control of dual-use technologies, and the legitimacy of decisions that affect the crew and future generations;
• continuity of funding, knowledge, and governance across several changes of generation.

GFF cannot and should not create all of this alone. Its intended role is that of a systems integrator: to maintain a shared map of dependencies, close the missing links, bring partners together, and decide whether to continue the program on the basis of data.

5. Science: a parallel portfolio, not a single bet

We do not stake everything on one physical hypothesis. The portfolio of propulsion principles:

• Engineering branches (A) — directed energy and sails, fusion propulsion, antimatter, autonomous systems. They rest on known physics, but they require major engineering problems to be solved.
• Metric branches (B) — controlled curvature of spacetime (warp): the frontier of physics, with strict admission criteria.
• Wormholes (C) and more distant hypotheses (D) — research mode only, with admission and stopping criteria set in advance.

The discipline of honest science is the primary protocol: claim statuses FACT / MODEL / TESTABLE / HYPOTHESIS; an open Catalog of Hypotheses with preregistration (predictions and methods are fixed before work begins); null tests — experiments that deliberately seek refutation — with blind analysis of the data; a negative result is published and counted when resources are allocated. A limited protected quota for research into new physics (5% of the science budget in the early Eras, rising to 10% from Era III) keeps room to explore risky ideas without turning them into the main engineering bet. Whether gravity can be controlled is tested in stages at gate G3.

Instruments of the science workstream — an open monthly seminar with an assigned critic, a hypothesis register, and an archive of materials — from the first year; peer-reviewed publications, an external scientific council, and an annual open conference — from Era I. Key results are not announced as a breakthrough until independent verification, or a published plan for replication.

6. Decision gates G0–G6

The path is marked by seven gates. Each is fixed by a verifiable artifact, not by opinion:

A “no” at a gate means an action planned in advance: further verification, a change of priorities, a shift of the date, or closure of a direction. For new physics, a negative result strengthens the engineering branches that rest on known principles. The strategy is reviewed every 10 years and at every gate.

7. Seven Eras: 2026 → 2201

The years after G1 are scenario markers, not calendar commitments. A new Era begins only after the scientific, engineering, financial, and institutional conditions of the previous one are closed. If a critical dependency is not ready, the transition is deferred, or it proceeds in a limited mode with the gap recorded explicitly.

8. An institution that outlasts generations

Today's team will not be able to carry the program to completion, so succession is designed from the first stage.

• A horizontal federation of 6–8 equal regional hubs on different continents, with no single point of control or failure. Regional neutrality is a measurable metric (any region's share ≤50% by 2030, ≤35% by 2035).
• Each hub has three levels: scientific (level 1 — laboratories and grants), technological (level 2 — a company portfolio that earns and reinvests), and public (level 3 — education, a talent pipeline, and a media franchise). The levels feed one another: profit → science, discoveries → companies and content, the pipeline → people.
• The “Foundation” structure holds the Charter, the Codex, the archive of decisions, and the knowledge base, but it does not run the daily work of the hubs. An independent trust provides legal continuity, and a digital Archivist helps check decisions against the long-term goal. Its conclusions are advisory and pass an independent audit.
• Protection of independence: limits on any single donor's share, disclosure of conflicts of interest, a 75% supermajority of the Congregation to change shared goals, and a procedure for a hub's peaceful separation if there is a fundamental disagreement.
• Passing on the mission: each generation reaffirms the Codex, strategic decisions are documented together with their grounds, successors are prepared in advance, and education and specialist training receive at least 10% of the budget in every scenario.
• The rule of managed completion: if the institution stops producing results, or if other organizations solve the task better, the plan provides for cooperation, a transfer of knowledge, or completion of the program.

9. Economics and funding resilience

Science on a horizon of centuries cannot depend on one patron or the fashion of a decade.

• Technology portfolio: creating and supporting companies in sensors, energy, robotics, and space and education technologies. The model accounts for a high rate of failure and relies on median market figures, not on the best individual cases.
• Planning ranges, not a forecast: $1–3 million per year in Era 0 → $10–60 million per year and an endowment of $100 million by the end of Era I → a portfolio of $3–5 billion and an endowment of $1 billion by the end of Era II. The scale of programs increases only after sources of funds are confirmed. Promises and unsigned intentions are not counted as income.
• The base rule: by 2050 the institution operates without critical dependence on donors (own income ≥40%). The endowment funds a baseline mode of work — theory, the Catalog of Hypotheses, the archive, and specialist training — that is preserved if the budget is cut. Donors and portfolio companies do not gain the right to change scientific conclusions or the program's goals.
• The contraction scenario is described in advance: trigger conditions, the order in which work is closed, and protected baseline functions. Budgets and the value of the portfolio are checked against actual data on a regular schedule.

10. Scenarios and risks

Planning runs across four pace scenarios: an accelerated case, a baseline case, a delay of 20–40 years, and a case in which metric modes of travel are forbidden or impractical. Paths for AI are considered separately: broad access, concentration among a few actors, heavy regulation, or a major incident. Each scenario has observable conditions that switch it on, and predefined changes to the budget and the portfolio.

The risk register names an owner, early signals, mitigations, and residual risk. It covers scientific error and results that cannot be reproduced, the safety of dual-use technologies, dependence on donors and suppliers, conflicts of interest between science and portfolio companies, institutional drift, loss of data and competence, legal constraints, international fragmentation, and loss of public trust. The register is reviewed every year and before every gate.

11. A place in the ecosystem: together, not instead

Breakthrough Initiatives, the Limitless Space Institute, Tau Zero, i4is, and other organizations already hold knowledge, teams, and programs that should not be duplicated. We regard them as potential partners for joint research, exchange of data, and independent verification of results. GFF's intended role is long-term integration: a shared map of dependencies, the discipline of the gates, and the link from fundamental science to engineering, economics, education, and an institution of succession. Partners must confirm this role in Era 0. It is not declared by one side alone.

12. The near term: 2026–2028

Era 0 (2026–2028) is a volunteer phase of reviewing the strategy and forming the founders' circle. Until G0 is passed, no large administrative structure is created and no capital-intensive programs are launched. The results of this stage:

• Founding Summit: a working meeting of 30–50 scientists, engineers, entrepreneurs, investors, people who build institutions, and independent skeptics.
• Independent review of the strategy: examination of the physical, engineering, financial, and institutional assumptions; publication of objections, changes, and questions that remain open.
• A small science workstream: an open register of at least 10 hypotheses, a null-test protocol v0, at least six seminars with assigned critics, and two or three small grants.
• Technology Atlas v1: a single map of directions, dependencies, current readiness, stopping criteria, and potential partners.
• Institutional design: the Charter, the Codex, the architecture of an independent custodian, and the rules for hubs, succession, conflicts of interest, and scientific independence.
• By gate G0: a circle of 3–5 participants in each of at least three regions, ready to take responsibility for creating regional hubs and to adopt the Era I plan together.

The offer to partners is to take part in the review and in joint design

• Scientists — shape and critique the Catalog of Hypotheses
• Engineers — build the Technology Atlas and the system budgets
• Entrepreneurs — test applied markets
• Investors — assess the resilience of the financial model
• Institution builders — design governance and succession

What is valued at this stage is a competent contribution that makes the program more testable and more realistic, rather than agreement with the source document.
