> What causes wave function collapse in the quantum realm? A conscious observer. Definitely not, this is a common misconception - an "observation" that causes a wave function collapse in the quantum realm is any physical interaction with external macroscopic environment, entangling the previously temporarily isolated system with everything else again. There's no relationship whatsoever with consciousness, there's not even the concept of "an observer", only "observation" e.g. when the measurement apparatus becomes entangled with the state of the studied system.
