So, I gave a pop quiz to my class today because I asked them if they had any questions about any of the material we’ve been recently going over (logic) and no one had any questions. Because of their confidence I gave them a quiz, which resulted in very interesting answers. One of the questions was to describe some possible world. Simple enough, right? If they knew what a possible world was they could write something simple down like “there are pink elephants” or “my shirt is red instead of blue.” However, I got this very interesting one that made me think. Think about it and let me know how you would respond to this scenario. It assumes a lot about knowledge, minds, God, etc.
In a possible world there is no predictability. Nothing that happens once happens again a second time. There is no way to know what is going to happen but there is also no such thing as knowing because there is nobody to know anything since a being would require repeated processes to function and remain functioning.

The Word of the Week is: Modal Realism
Definition: Modal realism is the idea that all modal possibilities are actual.
More about the term: Anything that is possible actually happens. However, modal realism is, in a sense, modally limited. The state of affairs of the non-existence of anything cannot be true if something does exist so by definition modal realism must entail ~∃!W with W being the non-existence of anything—nothing, lest it suffer the consequence of being intrinsically incoherent (~∃!W = There does not exist just one W). In order to avoid an inherent incoherence perhaps there are logically antecedent reasons to affirm ~∃!W (i.e. actuality is logically prior to possibility, which makes possibility somewhat superfluous). Under certain multiverse scenarios different regions of space will exhibit different effective laws of physics (i.e. difference constants, dimensionality, particle content, relation of information, information propagation, etc.) corresponding to different local minima in a landscape of possibilities.
