   This is wrong, because what we call 'stars' are actually points within   
   our own home galaxy.   
      
   Such points are not even stable with respect to our own galaxy, be our   
   galaxy moves, too.

   I would regard the so called 'big-bang' as a 'white hole'.   
      
   A 'white hole' is kind of 'back-side' of a black hole.   
      
   Since the white side follows the black-hole-side in time, we could say:   
      
   the 'big-bang' is the temporal future of the 'big crunch'.   
      
      
   Now: this 'temporal order' is not THE order, but only one possible   
   (temporal) order (out of many).   
      
   This means, that 'big bang' is actually 'relative' and dependent on our   
   own axis of time.   
      
    From this would follow, that we cannot even regard 'big bang' as an   
   absolute anchor in time, because every possible universe would have an   
   own 'big bang' which all are different.

   Sure, but we cann't, because we can only see into our own past-light-cone.   
      
   The 'real space' is mainly invisible.
