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)
