Time Travel Paradoxes And Multiple Histories

If time travel is possible, it seems to inevitably lead to paradoxes. These include consistency paradoxes, such as the famous grandfather paradox, and bootstrap paradoxes, where something is created out of nothing. One proposed class of resolutions to these paradoxes allows for multiple histories (or timelines) such that any changes to the past occur in a new history, independent of the one where the time traveler originated. We introduce a simple mathematical model for a spacetime with a time machine and suggest two possible multiple-histories models, making use of branching spacetimes and covering spaces, respectively. We use these models to construct novel and concrete examples of multiple-histories resolutions to time travel paradoxes, and we explore questions such as whether one can ever come back to a previously visited history and whether a finite or infinite number of histories is required. Interestingly, we find that the histories may be finite and cyclic under certain assumptions, in a way which ext Sep 24, 2020 ... If time travel is possible, it seems to inevitably lead to paradoxes.

The Paradox Of Time Travel, Answered!

Everyone has, at least, once in a lifetime thought of the idea of time travel. “What if I could go back in time and change the course of my life.” Time travel was made extremely popular with the release of the blockbuster movie, “back to the future.” Since then many science fiction movies have emerged with time travel as the center of their plot. Time travel has always been linked to science fiction and unachievable but Einstein's theory of relativity has opened new doors. It has shown us that t May 7, 2021 ...
