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.
