   Nature does not care about what we need.   
      
   Nature is as nature is, whether we like it or not.

   My own approach was, that time is local and space is 'relative'.   
      
   To get such a behavior I have searched for something, which would allow   
   such behavior.   
      
   This is actually possible, if you think about a certain type of complex   
   numbers and a connection between them, which is also known as certain   
   type of geometric algebra.   
      
   So, we need a system, which allows an imaginary time 'axis' at every
