Quantum mechanic’s double slit experiment describes perception as fundamental. Measured, while under observation light particles pass through one slit, when not observed they act as a wave passing through either. Quantum says perception is key, depending on whether it’s observed particles act as either a wave or single particle.
Science now speculates on quantum consciousness. Monist theory questions matters existence suggesting it is an epiphenomenon for communication between conscious agents. We are altered consciousness of the collective, multiple personality disorder. The videos on the belief page discuss. We’ve always thought consciousness a product of the brain. We are most interested in matter but certainly the non material exists, you. Consciousness, like the atom, is stuff of the universe and must be accounted for.
