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)
