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. 
 (One  Option  Could Be  Several Portals)
