Here is a somewhat related concept and extremely interesting called The Object Loop:
An object from the future is sent into the past, takes The Slow Path back to the future, and then gets sent back into the past again, in the same way, for the same purpose. For example, you travel to the past and sell a pair of antique glasses you got from a friend, who inherited them from his grandfather, who bought them from you, the time traveler. This time loop results in several important physics problems, such as:
Where did the glasses come from in the first place? The glasses have literally sprung into existence from nothing, appearing to violate the law of conservation of energy/mass. This is sometimes called a “closed timelike curve” in hard SF.
How does the object escape erosion or other forms of damage? Since its origin point is also its end point, the object cannot (relative to itself) loop endlessly as it would experience infinite decay (relative to itself) and therefore would not exist to be sent to the past, preventing the loop from occurring at all. Thus, to exist the object must (improbably) escape all forms of damage/erosion/entropy between its arrival and departure; technically, this isn’t impossible, but its improbability makes object loops very weird from a quantum mechanics perspective.
We hope you like the video and that we can all come closer to understanding this phenomenon that has intrigued the world for millenia!
