Grandfather paradox says the riders on the ship won’t experience most of the time of the ride

  >Grandfather paradox says the riders on the ship won’t experience most of the time of the ride No. The Grandfather Paradox[0] says nothing of the kind: The consistency paradox, commonly known as the grandfather paradox, occurs when the past is changed in any way.[5] The paradox of changing the past stems from modal logic: if it is necessarily true that the past happened in a certain way, then it is false and impossible for the past to have occurred in any other way, so any change to the past would be a paradox.[13] Consistency paradoxes occur whenever any change to the past is possible.[6] A common example given is a time traveler killing their grandfather before their parents' conception, thus preventing the conception of themselves. If the traveler were not born, they could not kill their grandfather; therefore, the grandfather proceeds to beget the traveler's ancestor who begets the traveler. This scenario is self-contradictory.[5] One proposed resolution for this paradox is that a time traveller can do anything that did happen, but cannot do anything that did not happen.[5] Another proposed resolution is simply that time travel is impossible.[14] [0] https://en.wikipedia.org/wiki/Temporal_paradox https://en.wikipedia.org/wiki/Temporal_paradox

    Sorry I spoke quickly. I meant the twin paradox and reached for the wrong label
