Now I am become Death, the destroyer of worlds. - J. Robert Oppenheimer

There is a theory of alternate realities that posits that whenever a decision is made, two universes split off and start divergent timelines. In one universe you chose left, and in the other you chose right kind of deal. If you consider this from a singular point of view, accounting for all the decisions you make in just one day, the number of universes you are creating is astronomical. When you multiply that number by all the decisions everyone is making simultaneously, as well as their downstream consequences, the number of possible universes being created according to this theory is basically infinite.

So, what does this have to do with Oppenheimer?
