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.
