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.
