I conjecture: In a quantum multiverse, one’s consciousness is a composite of the many worlds.
You’ve been warned folks: I’m-a get metaphysical on your asses. What’s worse, it’s a personal, almost solipsistic metaphysics. Hell, it’s my blog, why can’t I? I might also add that the next couple of conjectures will be the most controversial, and to some extent they might contradict each other. Consider it an appropriate quantum superposition–both simultaneously half true.
Few subjects in the sciences are as controversial as the notion of quantum consciousness, as it meets at the junction of theoretical physics and cognitive psychology, and manages to merge the two phenomena that puzzle scientists the most. Oh, we understand what quantum mechanics is in terms of what it does, but have no freakin’ idea how and why it does it. You can say pretty much the same for consciousness.
The concept of quantum consciousness is nothing all that new. Without getting too technical–because hey, then I wouldn’t understand it either–the notion of a quantum mechanical basis for human consciousness was first directly proposed by Roger Penrose, in his 1989 book, The Emperor’s New Mind. Built on his earlier work with Stuart Hammerhoff, Penrose asserted that the human mind can perform functions that are not computable and could only arise from quantum superpositions occurring within the brain. Max Tegmark, an MIT cosmologist with no shortage of his own controversial ideas, became the most vocal opponent of this concept, for reasons I won’t go into here, as this is not exactly what I am advocating. Or maybe it is.
What I am advocating, whether the mind is a quantum computer or not, is that our conscious experience represents a composite of all the universes, or potential universes suggested by quantum theory. The distinction between potential and actual alternate universes implies the distinction between the Copenhagen and Many Worlds interpretations of quantum mechanics. And the former seems to make more sense in concert with this conjecture, as it asserts that there simply is no objective reality on the sub-atomic level until we measure it; there are, effectively, only statistical probabilities. From that it would be easy enough to make the philosophical assertion that our consciousness is essentially a composite of all the possibilities.
But it might not be. As we only appear to be conscious in one reality at a time, it is certainly within the realm of feasibility to assert that consciousness is a composite in the Many Worlds scenario as well. If the Many Worlds interpretation is willing to accept that these universes can interact with each other on the sub-atomic level to produce the wave interference pattern described in Quantum Weirdness 101, why not accept that our consciousness does the same thing? Therefore, consciousness would be a composite across actual, physically real worlds. David Deutsch, in his book The Fabric of Reality, makes the case that the quantum multiverse is the enabler of free will; from this I would infer he means consciousness as well. But the Many Worlds interpretation suggests something perhaps darker and more sinister, even frightening. I’m bound to get flamed to no end for even bringing it up–it will be the subject of Conjecture #5. I call it quantum solipsism.
My bottom-line position on the composite consciousness conjecture: It’s a strong possibility. I see evidence of it in my own life; but it would take a volume, let alone a blog post, to fully recount. The best way to sum it up? The Rolling Stones quote above. It seems I rarely get exactly what I want, but often get what I need, and just in the nick of time. What? You say you don’t get what you need? Well, read the next conjecture. It seems that may not be my problem!
