I just finished watching a Nova episode on PBS about how the earth's magnetic field can reverse direction. Compasses that pointed north before suddenly point south, instead. These flips begin when pockets of reverse polarity appear in the opposite hemisphere, and weaken the magnetic field until it flips upside down. These flips usually happen every 250,000 years, but we haven't had one in over 700,000 years. We're quite overdue for a reversal, and there is mounting scientific evidence that such a flip may have begun.

And to add to that evidence, today there's this: Indians 22, Yankees 0.

The momentum between the opposite poles of the Red Sox and Yankees looks like it's reversing. The Yankees, who were cruising for most of the season, look terribly vulnerable now, while Boston looks like a steamroller. Just 3 1/2 games separates the two. Is a flip imminent?

Magnetic North has ruled the compass for an exceptionally long time. Unless you believe in some kind of supernatural intervention, some kind of blessing or curse, Magnetic South must eventually have its day. The flip will come. But whether it comes this year, or next, or another 700,000 years from now, only time will tell.
