A one-dimensional Minkowski diagram (\(c\,t\)-\(x\) coordinate system) with sketched simultaneous events for the coordinate system. The simultaneous events are always parallel to the spatial axis of this rest frame of reference.

  • \(\class{red}{E_0}\) and \(\class{red}{E_1}\) happen at the earlier time \( c \, \class{red}{t_1} \) in the rest frame.
  • \(\class{blue}{E_2}\), \(\class{blue}{E_3}\) and \(\class{blue}{E_4}\) happen at the later time \( c\,\class{blue}{t_2} \) in the rest frame.
