Upsides To Making A Portal To Heaven  
   To   Build   The  Factory   There    
  
                                          
 First  Of All,  Real Estate:  The Highly 
 Fractalized  Geometry  (Not  Proven  But 
 Likely  To Be  The Case) Implies  Almost 
 Unlimited Room; Even If The Portal  Tech 
 Would  Be  Stolen,  Chances  Of  Running 
 Into  A Competitor  Is  Close  To  None, 
                                          
 Secondly,  The  Resources:  Heavens  Own 
 Alchemical  Properties   (Proof  Exist!) 
 Makes  Most  Base  Materials Easily  And 
 Readily  Available.  Once  The Molecular 
 Movement  Patterns  Are Mapped  Out, Any 
 Compound   Can  Be   Created   Virtually 
 Without                            Cost. 
                                          
                                          
  
   Downsides To  Making  A  Portal  To  
  Heaven To  Build The  Factory  There  
  
                                          
 Current  Portal Tech Takes  Some  Energy 
 To Hold Open,  Which Isn'T  A Problem In 
 Itself. Test Results  However Has  Shown 
 That  Without An Active Tether, Heaven'S 
 Time Flow  Breaks Down Completely.  Even 
 A Momentary  Fluctuation  Of The  Portal 
 Would   Render   All    Remote    Assets 
 Practically  Lost.  Much  Care  Must  Be 
 Taken  To  Maintain  Portal   Stability. 
 (One Option  Could  Be Several  Portals)
