An article came out recently about a proof that time travel would not lead to the butterfly effect. https://www.popularmechanics.com/science/math/amp34146674/paradox-free-time-travel-is-possible/ . This sounds great but does anybody understand it enough to explain it to a novice? Has this idea been around for a while, because Netflix's show The Umbrella Academy touches on it? The article says that the proof is backed up by research from Los Alamos and some experience with random walkers. I am pretty familiar with the latter. My experience is that some random walkers, a recursive path search, and patience can solve a lot of basic computer science problems.
