The "material world" refers to the physical universe that we can see, touch, and interact with. It includes everything made of matter, such as rocks, plants, animals, and human-made objects. This world is governed by the laws of physics and chemistry, which explain how these materials behave and interact with one another. In contrast to the material world, there is also a non-material realm that includes thoughts, emotions, and ideas. While the material world is tangible and measurable, the non-material aspects are more abstract and subjective. Understanding both realms helps us grasp the full scope of human experience and existence.
