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.
