Philosophers question whether these paradoxes prove time travel impossible. Some philosophers answer these paradoxes by arguing that it might be the case that backward time travel could be possible but that it would be impossible to actually change the past in any way, [93] an idea similar to the proposed Novikov self-consistency principle in ...
Even without knowing whether time travel to the past is physically possible, it is possible to show using modal logic that changing the past results in a logical contradiction. 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.
Time travel in modern fiction is sometimes achieved by space and time warps, stemming from the scientific theory of general relativity. [9] Stories from antiquity often featured time travel into the future through a time slip brought on by traveling or sleeping, in other cases, time travel into the past through supernatural means, for example brought on by angels or spirits.
It certainly will imply that intelligent beings cannot change the past. Such change is incompatible with the principle of self-consistency. Consequently, any being who went through a wormhole and tried to change the past would be prevented by physical law from making the change; i.e., the "free will" of the being would be constrained.
The theoretical study of time travel generally follows the laws of general relativity. Quantum mechanics requires physicists to solve equations describing how probabilities behave along closed timelike curves (CTCs), which are theoretical loops in spacetime that might make it possible to travel through time.
But that change is difficult and it requires tremendous alignment with boards and with organizations’ workforces and tremendous vigilance on the part of the leaders that are driving that change.
Eternal return (or eternal recurrence) is a philosophical concept which states that time repeats itself in an infinite loop, and that exactly the same events will continue to occur in exactly the same way, over and over again, for eternity.
