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)
