A theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence. The process of creating a theory typically involves observation, hypothesis formulation, testing through experimentation, and revision based on results until a reliable and comprehensive explanation is developed. Theories can be refined or replaced as new evidence is collected, leading to a better understanding of the phenomenon being studied.
