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.
