Q&A: Super facts about the Super Bowl

Super Bowl site selection

I see the Super Bowl will be at the Superdome — again. How many times has it been held there, and how do the sites get determined?

Sunday's Super Bowl XLVII (47) will be the seventh held in the Superdome in New Orleans — the most in any stadium. The others were in 1978, 1981, 1986, 1990, 1997 and 2002.

There were also three Super Bowls at Tulane Stadium in New Orleans — in 1970, 1972 and 1975.

Miami has also hosted 10 Super Bowls. Five were held in the current home of the Miami Dolphins, Sun Life Stadium — in 1989, 1995, 1999, 2007 and 2010. The other five were in the Orange Bowl — in 1968, 1969, 1971, 1976 and 1979.

Seven have been held in the Los Angeles area: at the Rose Bowl in 1977, 1980, 1983, 1987 and 1993; and at the Coliseum in 1967 and 1973.

Tampa is next on the list with four: at the old Tampa Stadium in 1984 and 1991; and at Raymond James Stadium in 2001 and 2009.

The sites are selected in a vote of the 32 NFL owners. Interested cities submit bids, and the owners vote in a secret ballot or ballots. If no city is chosen on the first ballot, the one with the lowest total is dropped and owners vote again. This continues until a city gets two-thirds of the vote, or until there are two cities left to consider. If it comes down to the final two, a simple majority vote decides the winner.

Sites for the next two Super Bowls are set. In 2014 it will be played in MetLife Stadium in East Rutherford, N.J., and in 2015 it will be played at the University of Phoenix Stadium in Glendale, Ariz.

A look at space, decomposition

What would happen to a human body in space? Would it decompose?

Scientists and researchers aren't sure, Kenneth V. Iserson, professor emeritus of emergency medicine at the University of Arizona and author, told the Atlanta Journal-Constitution in an email. Iserson wrote Death to Dust: What Happens to Dead Bodies? and shared his theories from the second edition of the book, which was published by Galen Press.

"Based on the nature of space and the factors that cause a body to decompose, however, one would suspect that a human corpse in space would decay just like any other body as long as it was sealed under an atmospheric pressure approximating that of Earth," Iserson wrote.

He added that if a body was "rapidly exposed to the near-vacuum of space, it would disintegrate or very possibly explode," but if it was slowly introduced to the vacuum, it would stay frozen while receiving amounts of radiation.

"The normal mechanisms which cause a body to decompose, autolysis, putrefaction, and exposure to insects and animals, would fail to disturb an ice-cold body in deep space," Iserson wrote. "The only change would be a gradual drying of the body — creating a freeze-dried mummy."
