Physical reality refers to the tangible world around us, consisting of matter and energy that can be observed and measured. It includes everything from the smallest particles, like atoms, to vast structures, such as galaxies. This reality is governed by the laws of physics, which describe how objects interact and behave in space and time. In physical reality, our senses help us perceive the environment, allowing us to experience phenomena like light, sound, and gravity. Scientific methods, including experiments and observations, are used to understand and explain these phenomena, contributing to our knowledge of the universe and its workings, including concepts like quantum mechanics and relativity.
