The premise of time travel is already magical thinking.. They're generally pretty vague about how exactly plotting coordinates works in the stories.. .
There's no calculations in that above article… if our physics are at all accurate, it suggest something else about black holes and "space-time" curvature.. even where the theory of relativity comes into play, time is still an abstract measurement and a relationship of motion.. and it reaches extremes in points of singularity, extremes being relatively infinite motion, and relatively 0 motion.. and in equations this also gives you relatively undefined motion.. and so there's reaching ideas about a cup showing up in the spaceship of the people approaching a black hole who will later drop a cup into it.. but this hasn't been observed and really none of the above has been observed.. its not understood. But nothing strongly supports the fantasy that energy and matter are sustained in every instance it ever was, and could theoretically be navigated via "time travel"
It's amazing that its difficult for people to imagine that everything is just moving.. there is no official time.. we just set ours to the sun because its useful… it's just all moving… and we remember where it was before, but its not still there just because we remember it.. it moved. it doesn't go back. Maybe it eventually cycles forward to the same or a similar position, but it doesn't go back and its not still there to find again and rearrange all trajectory.. time is a measurement, its an idea.. the shit moving is real…
If anyone is a "time traveler" they're more likely… somehow inspired by a previous cycle… in which case.. there'd be plenty of time, if preserved by some undefined motion during a massive cycle of the universe, to drift back to the necessary position.. but you wouldn't have traveled thru time.. you would have just moved, actually very slowly..
