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.
