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)
