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)
