I will refer to this wikipedia page: https://en.wikipedia.org/wiki/Bell%27s_spaceship_paradox and especially this diagram:
It appears clearly in frame S' that the length of the rope is longer than at rest in that referential, therefore it breaks. Nevertheless, I can't see why in the S frame the rope should break as for the S frame point of view, the length of the rope stays the same (L).
Can someone explain how in this diagram the S frame should conclude as well that rope breaks ?
The argument given in the text is that the rope moves so it experiences Lorentz contraction from a frame S point of view. But this does not seem to appear on the diagram, or does it ?
Thanks for your help.
