Back to simplicity theory..
What motivates us to seek complexity? Is it an egocentric human failing? String theory is a perfect example of seeking explanations of reality on a level so complex that the mathematics cannot be fully developed to justify the theory, not that it should or would in any event. And yet the proponents of this theory are given immeasurable respect as leaders among the community. This theory cannot be tested, let alone proved, as it represents a sub-quantum scale, and we barely understand QM, only observe it.
The theory that the sun is a
colossal nuclear furnace within a mantle of iron surrounded by a sea of plasma is a simple theory, but the evidence for it is compelling. At least I think it is a simpler theory than the one which had been historically accepted, that it is just a super-dense giant gas ball. Simpler because it just makes more sense. The sun has a magnetic field around it, giant gas balls do not. The degree of simplicity of a theory is subjective to the observer, and is dependent on the degree of comfort which one feels with it (I agee with you, tinytree). That comfort is directly proportional to the related knowledge of which the observer is aware to the theory in question.
