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.
