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)
