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)
