I have a question I've been wondering for a long time, I'm not sure if it belongs here but I assume that QM people might be able to answer it. Einstein said the following: If physical objects are not "in space", then what are they existing "in" per se? And most importantly when we consider "insideness" vs "outsideness" (an idea in our minds vs the "outside world" Is the concept of subject vs object incoherent? is an object both an object and a function at the same time? if we look at a car in the "outside world", the notion of a car in our minds is directly connected to the car in the outside world, i.e. there is no inside vs outside because reality is all connected at all times (no symmetry of existence, i.e. if existence exists, then everything that exists, must ultimately derive itself from a prior existence or the whole concept of naturalism breaks down completely). If we are derived from a prior existence (i.e. we are born from our parents, made of pre-existent matter and energy, etc), and everything in the universe is uniformly connected in ways we don't (fully)understand, and that this interconnectedness is the basis for naturalism. (i.e. naturalism becomes incoherent if we DON'T believe nature is all connected at all times). How is anything technically an "object" that is in the ultimate sense 'disconnected' from anything else in the universe? It seems to me that all objects are also functions at the same time. i.e. how is a particle of matter/energy distinct from all the rest of the energy in the universe, doesn't it all share and is made of the same ultimate energy? i.e. conceptually if we were to represent each object inside space it would look like everyone is trapped in a kind of strange gelatinous fluid in which we could move in interact.
