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)
