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.
