Is consciousness a hologram? I think so.
Why? I think it has something to do with the shape of the human brain. It makes sense to me that the morphology of the brain (any brain) has some impact on the way that brain works. After all, each body part, every organ, has a shape for a functional reason. So why does the brain--especially the human brain--look the way it does?
It isn't just about size, but also about shape. To begin with, what shape does a thought have? It is tempting to think of (a single) thought as some sort of electro-chemical process in the brain, like electricity traveling through a circuit, because this is how we have imitated the process of thinking in electro-mechanical devices. But the electric current that certainly underlies thought is not carried linearly as it is in wires, nor is it processed sequentially as a series of yeses and nos (even in parallel) the way that a computer circuit functions.
Thoughts are waves, and consciousness is an intersection of those waves, a hologram. Consciousness has something to do with the shape of thought and the human brain.
But what? Brains in general are not developed to the point of consciousness. In fact, only the human brain has managed the trick. Morphologically, a human brain is not so different from all brains, even very simple ones, but something is clearly different about the shape of the human brain. Something about this shape has allowed consciousness to emerge.
Time and Distance are the key variables in defining the shape of any space. The brain occupies a finite amount of space and has a defined shape. I propose that the effect of the constant intersecting and reflecting electromagnetic waves (thoughts) within the brain space is perceived as sensation, a basic function of all brains, but in humans, it comes with a holographic interpretation of that sensation. In a word, consciousness.
