Abstract
The Time Anchor Project began as an independent thought experiment in 2013. Anchor 001 is its proposed physical realization: a permanent place designed to become a known point in spacetime.
1. Purpose
Make a moment findable. Preserve enough information about who, where and when that future readers can reconstruct its context.
2. Definition of a Time Anchor
A Time Anchor joins a durable physical reference point with human-readable records, time and location data, redundant archives and long-term stewardship.
3. Scientific Context
Archival conservation, materials testing, geodesy and digital preservation supply practical methods for designing and evaluating records.
4. Scientific Limitations
No demonstrated mechanism exists for sending controlled information backward through time. The Time Anchor asks what we would wish we had left behind if a future discovery made it possible.
5. The Time Anchor Hypothesis
An exceptionally well-documented place or event might give a future technology something in the past to aim for. The preservation work explores what such a record could contain and how it could survive.
6. Anchor 001
PROPOSED REGION: EAST TEXAS. TARGET: 2030. STATUS: PLANNING. Proposed region. Final location has not been selected. Site selection, design, resources and stewardship will shape the final schedule.
7. Choosing the Site
Compare geology, drainage, climate, accessibility, archaeological context, land tenure and long-term maintenance. Site documentation should make the reasoning and survey methods understandable to future custodians.
8. Temporal Reference Protocol
Record the clocks, time standards, coordinate systems, instruments and uncertainty of each measurement. Include terrestrial and celestial references and describe how they can be reconstructed.
9. Extreme Preservation
Test archival media and enclosures under heat, moisture, corrosion and physical stress. Document material degradation and failure modes. Published DNA preservation research can inform separate studies with appropriate scientific, ethical and privacy review.
10. Information Record
Preserve identity records, language and cultural context alongside the message. Layer ordinary text, diagrams, mathematics, units and examples so interpretation does not depend on a single machine or convention.
11. Physical, Digital, and Cryptographic Archives
Maintain independent copies on media with different failure modes. Use integrity checks and documented custody; preserve the formats and instructions needed to interpret both the record and its checks.
12. Distributed Observation and Public Witnesses
A proposed public Anchor event could bring independent instruments and witnesses together to document a shared moment. Distributed records could preserve multiple views of the same event.
13. Talk to Tomorrow
Talk to Tomorrow is an online public time-capsule message stream. Display names are optional, messages are limited to 500 characters, and no email is required. Future physical archival inclusion requires separate explicit consent.
14. Detection Criteria and Falsifiability
Define measurement procedures, calibration, ordinary sources of error and independent review before interpreting unusual observations. Preservation experiments should publish test conditions and outcomes.
15. Replication and Future Anchors
Compatible reference records and open formats could let future Anchors share methods and distributed copies while adapting to different sites and environments.
16. Long-Term Stewardship
Document maintenance, custody, media replacement and succession. Stewardship is part of the archive, not an assumption that the original makers will always be available.
17. Museum and Public Education
The longer-term vision includes a science, preservation and science-fiction museum and event space: a place to explore what survives and what people choose to leave behind.
18. Governance and Ethics
A Pushplay project. Contact hello@timeanchors.org. Any work involving human biological material requires a separate review and consent process.
19. Funding and Transparency
Resources for future physical work should be tied to defined designs, experiments and stewardship responsibilities. The website does not accept payments.
Conclusion
We may never learn how to send a message through time. We can learn how to preserve one.
