The entire event is entirely make believe, there's not a shred of truth to the whole idea. How's that for an answer? By the way, the only meaningful number in the whole shebang is the 26,000 years, which is the time it takes the direction of the Earth's rotational axis to precess around in a circle. But this is a very gradual process and does not produce any effects like earthquakes, etc. Maybe there is a serious question here the Mayans might have known about the 26,000 year cycle, like the ancient Greeks did, but that's the only sensible question that might be residing there and I don't know the answer.
