What's up with the sun?
Here's another *FASCINATING FACT*: If you've got 2 objects a distance apart, it's possible to increase the distance between them without moving them because space-time and gravity are all tied up together. If something massive enough moves enough, it sends ripples in space-time through the universe, which in turn changes the distance between your objects.

OK, well how about this.
Every now and then the earth's magnetic fields reverse, so the north pole becomes magnetic south and vice versa. It may be in the process of happening now, though it takes a few thousand years to complete.
On the other hand it may just be having a think about it before changing it's mind and deciding it doesn't want to flip. This is, wonderfully, called an "excursion".
Its been 800,000 years or so since the last reversal though they aren't periodic and at other times may have happened 4 or 5 times per million years.
While in the process of reversal, there can be more than one north or south pole at a time. Which must confuse iron filings no end.
EDIT: The bits above come from the British Geological Survey but other sites claim there may have been a reversal 12,400 years ago, which is somewhat more recent than 800,000. So it's somewhere between 12,000 and 800,000.

Science. Blah. Didn't God create everything anyway?
