“One theory suggests a galactic alignment which would create chaos on Earth because of the gravitational effect between the Sun and the Black hole called Sagittarius A, which is located at the center of our galaxy.
Another theory involves a ‘polar shift’, which means a reversal of the north and south magnetic poles. Scientists believe that the Earth is overdue for a geomagnetic reversal. However this can take up to 5,000 years to complete and does not start on any particular date.”
At least, the History Channel has lots of programs on this topic.
