Can imagination be reduced to simple physical processes? Like neurons firing and carrying information that's collected, stored and processed. It appears that in imagination all known laws of nature/physics can be broken, down to the last one. Imagination seems to be limitless, almost like a trait of an omnipowerful entity, a human being can picture anything - even that which defies all logic and common sense. In terms of physics, the whole universe is supposed to make sense and be governed by laws. What laws would govern a limitless human imagination? And most importantly, since we have found that everything in the universe is made of something, be it zero-dimensional point particles or 1-dimensional strings, what is imagination(or an imaginary concept) made out of? If it's made of one of those listed particles, then that raises very serious philosophical questions concerning reality. And if you deny the existence of imagination/thoughts in our physical realm of existence, what kind of realm do they occupy and how do we define it in terms of physics?
