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)
