In other words, reality depends on a conscious observer.
This is easily demonstrated with the double slit experiment where the simple act of observation effects the outcome.
Taking this many many steps further and it is theorised that the whole of our reality is also dependent on such a conscious observer. But who or what could that be?
Sean Carroll, physicist and mathematician has theorised that the ultimate origin is a void permeated with infinite non description fields, each with the potential to collapse into a sub atomic particle. But how? By observation?
A weakness in his theory is the void, a multi dimensional, ''space,'' but any kind of space or void with dimensions holds the potential to contain something within it, and so this is not nothing. But it is a work in progress.
The fact of the importance of observation remains, combined with the mystery of consciousness, which we experience from our brain, but does not exist in any part of the brain that can be identified.
Other quantum field theorists have slightly differing approaches, but they now know they are dealing with the non physical.
I'll leave it there for now.
