>>39364532As per Alternate Branch Conduits, all you need is something that exists and doesn't exist at the same time, or something that is guaranteed to exist, but doesn't. I mean yeah, that sort of thing is kind of wonky because you are literally changing and merging timelines, but shit son, there are literally quadrillion googleplex timelines that run alternate to this one that are nearly fucking identical so it can't all be bad.
Now if you are pulling/merging from potentialities where "Oh shit, shit goes fuck because of a random variable" because you don't know what the fuck your putting your theoretical quantum dick into, then yeah its bad, but that chances of that can be easily fucked around with to make sure that your timeline doesn't end up to be that timeline where shit goes to fuck.
Fucking Black Mesa retards didn't do their preventative calculations.
