“What causes the collapse of the wave function? It is the entry of stimuli into the sensory apparatus of a conscious observer, such as photons of the right wave length hitting the human eye and entering the eye through a lens which focuses the light on to the retina. The retina then sends a signal to the brain via the optic nerve and the brain turns the information into the images we see. Those images and information from the other senses constitute the human sensory world. Clearly the images and other information could not exist without observation. Nothing else in the human sensory world exists without an observation being made, so why should the results of experiments, indicating the presence of quantum entities, which show in macro level experimental apparatus be any different?”
