Question;  What do you see when you look at a Spiral Galaxy.  ?    Answer;   A Galaxy with a Spiral.  Sorry, wrong answer.  The   correct answer  is :    A Galaxy with Twin Interlaced Spirals.  The reason for this answer,   is that  Galactic   Architecture,  is   an effect  of Galactic Core Jetting.   In the case of the Home Galaxy,  the Milky Way, the progenitor jetting body, is  Sagittarius  A*  ( pronounced Sagittarius a Star) and  Sagittarius A*  is jetting twin jets.  The jets of our Galactic Core,  were formed in the same instance, and they are  more or less  identical,   and the jets create  twin perfectly interlaced contrails.  However,  as the angular momentum of Sagittarius A*   acts to rotate the jets, in perfect unison, it will be apparent that  one jet will   forever    (almost)    be   destined to be  the trailing jet, and significant data  from  the metallic  content of each jet  contrail,   will, I predict be identified  as having different elements.  The  interlaced spiral architecture , is clearly observable, in many NASA    "  face on  Galaxies "  imaged by Hubble.  

Sagittarius A* does not appear to be a Radio Galaxy. otherwise  Radio Astronomers   would be aware of the radio jets  therefore,  it can be assumed  that Sagittarius A* ` s   radio jet has been disrupted. 

Jetting Black Toroidal Objects   jet exotic core material and fuzing plasma from the jet boreholes.  The bore holes  are a function of   the   "Internal Event Horizon " that created  the jet boreholes.    A   characteristic  of the   Internal Event Horizons is that     "  nothing can enter "   ie. the   bore holes  cannot collapse ( Just as nothing can leave the External Event Horizon )  .  The jets are fed via core collapse,  at the central point of Gravitational Equilibrium. The  bodies core,   is  in effect,  imploding at this  " local singularity "  .   However,   as the jet encounters, the  "transition zone,   and as it exits its   jet , it in all probability,  encounters,   the   Internal  /  External  "crossover sector"  or  "exit"  point,    of the boreholes,  where   ionised plasma   escapes , leaking,  from the jets,  and   establishes   spherical lamina  flow  zones,  around the  "external "event horizon.  The  ionised plasma,  eventually   completely envelopes    the sphere,   closing  in upon the bodies   magnetic dipoles  exit points, where the   Spherical Ionised Layer  encounters  the  North and South  polar zones, and the ionised plasma  generates  the Radio Jets.
