The role of a scientific theory is to provide a coherent explanation for a set of related observations or phenomena. Theories are based on extensive empirical evidence and can integrate a wide range of data from various studies. They serve as frameworks for understanding natural processes and guiding future research. A robust scientific theory can be tested and refined over time, distinguishing it from mere hypotheses. Ultimately, theories advance scientific knowledge by facilitating predictions and enabling researchers to explore new areas of inquiry in their fields.
