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.
