Ahh, there is the point though, it lies in the concept of simultaneity, 
which really depends on whether space-time is Minkowskian or Galiliean 
doesn't it? Despite the lack of proof for or against either one, I 
prefer Galilean because a) time is absolute and b) I can understand it
without getting a headache...<G>
