Theoretical research is a type of investigation that focuses on developing new ideas, concepts, or models to explain phenomena. It often involves mathematical frameworks, simulations, or abstract reasoning rather than direct experimentation. This approach is common in fields like physics, mathematics, and philosophy, where researchers seek to understand underlying principles. Unlike applied research, which aims to solve practical problems, theoretical research prioritizes understanding and predicting outcomes. It lays the groundwork for future experiments and innovations by providing a conceptual foundation. The insights gained can lead to advancements in various disciplines, influencing both academic and practical applications.
