✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

DECIGO aims at the detection of primordial gravitational waves, which could be produced during the inflationary period right after the birth of the universe.

C2weakest assumption

The assumption that the required laser interferometry, spacecraft formation flying, and noise reduction technologies can be successfully demonstrated by the B-DECIGO pathfinder in time to enable the full DECIGO mission.

C3one line summary

DECIGO plans four clusters of three spacecraft each forming 1000 km arm Fabry-Perot Michelson interferometers in heliocentric orbit to detect primordial gravitational waves and other signals, with B-DECIGO as a technology pathfinder to launch in the 2030s.
