I genuinely don't know more about that. All I know is Looking Glass was fucked with for years and many specialists were brought in to try to solve the problem of timelines converging. Each time they entered different inputs, it would give several different outputs which were eventually gotten down to two scenarios: something really bad or something really good. The issue with the whole thing is that "the end of the world" is an ambiguous condition. The end of who's world? That's the question. The specialist(s) seem(s) to point to it leading to a positive outcome where lots of good things happen for most people on the planet. I guess the other option was really, really bad shit. Looking like it's going to be the "end of the world scenario". The good news is it doesn't seem like a bad thing.
