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.
