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)
