    Brian-
     
    
     Unless geology has changed theories again...I was taught that the magnetic 
    field HAS and will in fact go to zero and reverse, that there is physical 
    evidence in the rocks all over the planet that this is in fact the normal 
    cycle for our dear planet. I don't know about the dates and timeline, just 
    that over the ages the field does weaken and reverse on a regular basis.
