I think, the issue is not whether time travel exist or not. When one is emotionally invested in some tree( conspiratoral time travel), they tend to forget about the forest and all the tree's in the forest are looked with the same lens. Cognitive science addresses this bias. That is what we are trying to say.It seems to be accepted on this forum that 4th Density STS can alter reality. OK, if reality is being changed, then the question moves on to how/why some people can notice the changes and others can't.
