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)
