And no, we don't have to trust that anybody knows better then anyone else without evidence. And there is no timetravel in the story.
You missed my point by a lot. I never said that my problem was with quantum mechanics or timetravel or loops.
Just you missed my points. IMO Asking forscientific detail will lead to an endless Q&A about "fictional" mechanics. The writer of Star Trek and Star Wars also don't explain every thing in detail, because it's hardly relevant. As long as the writer does not flip the universe and disregard it's laws (like the Lightspeed suicide despite the enemies shield and deflector fully operational in Star Wars 8, that totally broke the Star Wars Universe) it's fine.
So i end with requoting Grizz:
I feel like you're looking for answers to questions that go beyond what's reasonable for a story
