A bunch of nonsense thought from someone who reads too much sci-fi: > https://news.ycombinator.com/item?id=29569437 https://news.ycombinator.com/item?id=29569437 In other words, it's perfectly ok to change the past and the universe doesn't so much self-censor as timelines always ultimately loop in some kind of meta-time back into each other. Another way to think of it is that it self-censors in the way that a delayed choice quantum eraser experiment does. The timelines which do not ultimately form part of a stable meta-loop structure destructively interfere with each other. Feel free to point out all the ways in which this is nonsense by the way. I love this sort of education through correction of ignorant armchair supposition.
