I agree that consciousness is very difficult to define. And because it is difficult to define, it is also difficult to develop a physics around it. But that is not going to stop me from thinking about it and wondering about it. What is consciousness? Where is consciousness? Why does it exist? I am not going to stop asking these questions just because they are difficult questions and I am not going to stop seeking just because the journey is difficult. I do believe that magnetism plays a role somehow which is by I spend a lot of time focusing on that. If that is true then physics does play a role. I don't have all the answers and I never will because every time I find the answer to one thing, I discover more questions.
