  1. Thanks Shelby for clarifying things. De Grasse Tyson is just parroting the official line of denial without giving proper due to science or the procession of stars and planets as mapped by the Mayans.

  2. Tyson says the earth, sun and galactic center come into perfect alignment every Dec. 21. That’s not quite true, because
    the ecliptic (plane of our solar system) precesses with respect to the galactic plane. It hsppens that we are in a period around 2012 when there is alignment. The precession cycle lasts about 26,000 years, which is also close to the great cycle of the Mayan calendar. This does not mean the world will end, that some Planet X or Niburu. For a lucid discussion of the astronomy see http://www.bibliotecapleyades.net/esp_2012_03.htm
