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)
