Understanding the Context

This article explores the definition of theory, its various types, and practical examples to demonstrate its significance across disciplines. The meaning of THEORY is a scientifically acceptable or plausible general principle or body of principles based on data and offered to explain phenomena. How to use theory in a sentence. A theory explains why or how something works, while a law describes what happens without explaining it.

Key Insights

Often, you see laws written in the form of equations or formulas. In everyday language, “theory” often means a guess. In research, it means nearly the opposite. A scientific theory is a self-consistent framework of laws, principles, concepts, and facts that has been verified experimentally and can accurately describe a system or field of study. In science, an explanation or model that covers a substantial group of occurrences in nature and has been confirmed by a substantial number of experiments and observations.

Final Thoughts

A theory is more general and better verified than a hypothesis. (See Big Bang theory, evolution, and relativity.)
