Also worth noting with that definition of time travel, logically it would seem, time travel would be self eliminating.
IE, I go back in time, stop whatever I would consider the worse event in history… thus putting the world on a trajectory where myself or whoever invented the time machine no longer happens, leading to someone else inventing it, going back for a different reason, also changing the trajectory of history also eliminating the events leading to his time machine’s creation. Effectively the dice keep re-rolling until we get a world where the time machine is either not invented or not used, most probably early human extinction.
