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)
