Don't worry about the long post. I can be pretty bad myself. Quantum physics happens to be an area of interest of mine, so much so that I will recommend "The Quantum Universe: Why everything that can happen does happen" by Brian Cox who has worked at CERN. The book will expose a lot of tripe that unfairly distorts what the quantum realm is all about by a lot of pseudoscientists out there. One is better off listening to the experts that deal directly with the area of research. Quantum mechanics are weird but that doesn't mean that something supernatural is going on. It's just that, for their calculations to make sense and predict an outcome, one has to assume that on a quantum level there is no such thing as possible and impossible, only probable and improbable come into it. Science does not yet have all the answers, but, let's not forget that quantum theory helped us to come up with the transistor, one of the greatest inventions of our time. The theory works even though there are many versions of it, some more hypothetical and others with more substance. The book mentions that the reader shouldn't be surprised if something like the Higgs boson was found - and surely enough they found it.
The belief in spirits and an afterlife is a different matter. I can't imagine why a materialist view would rob children or even adults of imagination. Many fantasy films and literature have been produced by creative and artistic individuals who grew up in materialism. In fact, I think telling children that an astral plane inhabited by ghosts exists can limit their scope and can discourage them from investigating or considering other worldviews if they live in the delusion that such esoteric views are an established truth. No hypothesis should be passed off as an established truth. This is why science has theories that are tested and lead to falsifiable predictions. Please understand that falsifiable does not mean false, but rather, in this context, that something can either be proved to be correct or incorrect via experimentation. Most of the time, because scientific theories are so substantial and involve calculations, their predictions turn out to be true.
To finalise, in the history of science there is not one shred of empirical evidence for the supernatural. They can find a particle that gives all other mass to different degrees and yet not a shred of evidence for a ghost inside the human body or a spiritual plane where the deceased supposedly go as discarnate being. The only evidence we have is that damage to the brain can destroy your mental faculties. I recommend that you take a look at Cristof Koch work, which is fairly recent, and the integration theory of consciousness. It won't be long before we solve this puzzle. To my satisfation, science has already demonstrated how, when we dream or hallucinate, the brain is making up realities in the absence or distortion of sensory input.
Lucid dreaming stands apart from the waking state and ordinary dreaming as a hybrid state in its own right. It bandwidth of brain activity is Gamma and the areas of the brain associated with self awareness and self-assessment light up. Check out the Planck Institute's findings on the lucid state. Very interesting and provides insights into the nature of consciousness.[ Post made via Android ]
