Vatican prepares secretive conclave to elect new pope, cutting off outside communication.

The Vatican is preparing for a secretive conclave to elect Pope Francis' successor, with 133 cardinals gathering in the Sistine Chapel. To ensure privacy, the Vatican will cut off mobile signals, install jammers, and enforce a lockdown. The conclave, starting on May 7, will follow centuries-old traditions, with cardinals isolated and voting in secret until a new pope is elected by a two-thirds majority. The process is steeped in ritual, with ballots burned to signal the outcome, and the movie "Conclave" has provided some guidance for cardinals unfamiliar with the procedures.
