Convergence Event

A convergence event is the designed dramatic moment at which independent teams in a blind-replication protocol see each other's results for the first time and confirm or fail to confirm agreement. Katherine Bouman's cross-correlation reveal at the July 24, 2018 Black Hole Initiative workshop, with the four EHT imaging teams seeing each other's images for the first time and confirming agreement above 95% pixel-to-pixel correlation, is the canonical example. The convergence event is what turns the embargo period into a designed arc rather than a procedural delay; its dramaturgy is what gives convergence-as-proof its epistemic and emotional power.
