Is there a casual relationship between some physical thing or event being possible and a possibility actually happening?
What i mean by this, could it be that the universe is constructed in such a way that a thing could happen due to a relational-probability and not strictly according to traditional causal-relationships (a domino hitting another domino).
To choose an extreme example, a house might randomly appear, that is to say that atoms might arrange themselves that way simply because it’s a possible outcome or because of a tendency towards that possibility given a particular situation. (It’s just an example, i am not saying that a house could just appear, but maybe things on a smaller scale could occur that way.)
This is to say that the universe isn’t just a bunch of cog-wheels producing a definite determined effect, but rather all manner of effects may be a result due to a selection of relational-possibilities, the mechanism of which we do not understand.
