For a long time people have been searching for a "theory of everything" bringing together the macro and the micro worlds. On the one hand people are searching for ever smaller particles. On the other hand people are talking about multiverses. Our own universe looks to be at least 40 billion light years across.
As far as I know there has not been a proper bringing together of the quantum world and our "everyday" world. According to quantum entanglement particles on opposite sides of the universe instantly know about each other. Clearly, there is so little we know.
Monism may be on the right track, if not the whole way. It views that reality is one organic whole with no independent parts.
