o   Earth Crossing of the Galactic Equator: Update and Correction
In Chapter 1 of Fractal Time, the 2012 alignment was attributed, in part, to Earth’s orbital crossing of the galactic equator. Deeper investigation has revealed that the sources for this data appear to be inaccurate. And while this equator-crossing perspective remains the opinion of some researchers, additional data strongly indicates that the alignment is due to Earth’s precessional wobble, and not the actual position of our solar system above, or below the galactic plane.

  • It is true that during the 250 million or so years that it takes our solar system to orbit the Milky Way’s galactic core, our orbit carries us above and below the plane through a path that looks like a sine wave.
  • Recent publications suggest a strong correlation between our location in this orbit and the energetic effects of the galaxy’s magnetic fields upon life here on Earth, including a shock wave that exposes the Earth to high-energy radiation every 64 million years or so.  “Cycles in fossil diversity,” Nature 434 (10 March 2005), pp. 208-210 (abstract).
  • Data suggests that we are between 50 and 80 million light years “north” of the galactic core, and nowhere near a physical crossing of the equator itself.

For clarity, the 2012 alignment is a positioning that is the result of the precessional wobble that completes each 26,000 years and not a physical movement from one side of the equator to the next. http://www.centauri-dreams.org/?p=1378: non-technical summary of these findings
