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)
