A nun follows a Mass taking place inside St.Peter's Basilica for the election of a new pope, broadcast on a giant screen, not pictured, in St. Peter's Square, at the Vatican, Tuesday, March 12, 2013. Cardinals enter the Sistine Chapel on Tuesday to elect the next pope amid more upheaval and uncertainty than the Catholic Church has seen in decades: There's no front-runner, no indication how long voting will last and no sense that a single man has what it takes to fix the many problems.
