The simplest natural science is often considered to be physics, as it deals with the fundamental principles governing the behavior of matter and energy in the universe. On the other hand, the hardest natural science is subjective and can vary depending on individual strengths and interests. Some may find fields like quantum physics or theoretical astrophysics to be particularly challenging due to their complex mathematical concepts and abstract theories. Ultimately, the difficulty of a natural science discipline is relative to the individual's background knowledge and level of understanding. **
