Spacetime-curvature navigation

Estimated year~2092

12% by 2097 · including earlier years

The year is an editorial timing estimate. The percentage applies to occurrence by the stated deadline. These estimates are not calibrated odds.

Craft navigate by sensing the curvature of spacetime with ultra-precise clock pairs, needing no outside beacons at all.
