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.
