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)
