Dimension Split (Time Travel)
Inquiry[edit]
The dimensions split at 1010 A.D. Does this mean that if two people traveled back in time from either dimensions after 1010 A.D., there'd be two of them in a single dimension?
Answer[edit]
Probably not. It is suggested that the dimensions are now complete, separate entities. Since dimensions are self-contained universes, Home World simply has the same history as Another up to 1010 A.D., after which it diverges. The Chrono series avoids paradoxes and probably would not create a case where the dimensional split literally happens at a branch on one worldline.
Inquiry[edit]
But can someone prevent the dimensions from splitting if they traveled back in time to Another World before 1010 A.D.?
Answer[edit]
This depends on whether the split of dimensions is protected by time traveler's immunity. Since acts of time traveling are, and since the dimensions, once split, are self-contained universes that exist all on their own, it would probably be impossible to prevent the split. Home World exists parallel to Another World and apart from it; even if you prevented the action that made things split in Another World, it still happened before you traveled back in time to stop it.
