   Now is actually now!   
      
   Time is most likely a local phenomenon and the point called 'now'   
   devides the continuum of time into past and future.   
      
   There 'future' is everything happening later than 'now' and 'past' means   
   everything earlier.   
      
   But we usually don't know, what happens now in remote locations, hence   
   the so called 'hypersheet of the present' is mainly invisible.   
      
   What we can actually see belongs to our own past light cone (only!),   
   because the future is invisible and also the present.   
      
   What we can see is therefore belonging to our own past.   
      
   Now the question: what 'topology' does spacetime actually have?   
      
   Well, I personally think, that bing bang theory is mainly wrong, because   
   the universe has no beginning and no end and therefore it makes not   
   sense to ask the question, which time 'now' has.   
      
   Time as we use it is based upon an arbitrary reference point in time, at   
   which we start to count days and years, hence beginn to counting of time.   
      
   This setting of a start had been done repeatedly in the past and for   
   various staring points.   
      
   Today we mainly use the alleged birth of Christ, which is assumed to   
   have happend 2026 years, 1 month and 23 days ago.   
      
   But we could use essentially any point in time, that is well defined by   
   whatever means we have.   
      
   Something located at that staring point in space and time will evolve   
   into the enviroment and roughly twothousandtweentysix years later ends   
   up here.   
      
   But possibly somewhere in a very remote past some kind of void actually   
   split apart and started to evolve into the future, while creating what   
   we call 'universe' today.
