text: Dr. Paul LaViolette suggests that the galactic center has phases of activity with outbursts of matter and energy he calls “galactic superwaves” which spread out from the center of our galaxy every 12-13,000 years and may have caused the Earth’s cycle of precession – the almost 26,000 year cycle of the precession of axial rotation – to fall in line with the galactic cycle.
