The Vatican - One hundred and fifteen cardinals gathered at Vatican City on Tuesday morning to begin the process of electing a new Pope, beginning a process that remains one of the most secretive in the world.
Seventy-seven votes are required to elect a new Pope, and with only one vote on Wednesday and four each day thereafter, many Papal observers do not expect a new Pope to be elected until Thursday or later.
Among the many secrets involved in the process is how the Vatican keeps the voting process from leaking.
What is known about the process is the Vatican is using cell jammers to prevent electronic messages from getting out about the voting process, and some Cardinals disguise their handwriting to keep their identities a secret.
Smoke Signals (CBS News):
To an observer of the papal conclave, there is one part of the process that is the most visible and exciting. On Tuesday, all 115 cardinals will isolate themselves from the rest of the world and their only contact with the outside world will be in the form of smoke signals.
What the fumes indicate is simple; black smoke means that there has been no decision on a new pontiff. But if the "fumata bianca," or white smoke, flows out of the chimney than the world knows there is a new Bishop of Rome. The color has to be just right, or millions of onlookers will be fooled.
But, just how does the smoke get its color?
"Most smoke is due to things not burning completely, producing tiny particles that float in the air. The color of that smoke depends on what those particles are made of," Robert Krampf, a science educator who calls himself the Happy Scientist told CBS News via email. "Black smoke is usually made up of tiny bits of carbon. White smoke is usually more complex, made up of fuel vapor, water vapor or mineral ash."
Originally, the Roman Catholic Church burned wet straw with the paper ballots to give the smoke its dark color, which worked for awhile.
"The idea behind the wet straw is to keep the fuel from burning completely. The incomplete burning produces the particles of carbon needed for dark colored smoke," said Krampf. "Unfortunately, wet straw gives you grey smoke, not black smoke. This has sometimes led to quite a bit of confusion, with people thinking that a new Pope had been selected if the dark smoke was not dark enough."
To eliminate the confusion, they've now moved on to using a chemical compounds to give the smoke the proper color. Along with white smoke, there will also be the ringing of the bells of St. Peter's Basilica to signal a new pontiff.
As CBS News' Bob Schieffer discussed on "Face the Nation," it is important that the smoke is the right color, because it's not just the locals that get confused, but the world as well.
"All eyes will soon be on that chimney again, and even in the age of Twitter, we'll all be doing what people have been doing for thousands of years, trying to read the smoke signal."
