Detailed explanation-1: -In everyday use, the word “theory” often means an untested hunch, or a guess without supporting evidence. But for scientists, a theory has nearly the opposite meaning. A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
Detailed explanation-2: -Regarding the term “theoretical" As a result, theories may make predictions that have not been confirmed or proven incorrect. These predictions may be described informally as “theoretical". They can be tested later, and if they are incorrect, this may lead to revision, invalidation, or rejection of the theory.
Detailed explanation-3: -A hypothesis is usually a prediction based on some observation or evidence. Hypotheses must be testable, and once tested, they can be supported by evidence.
Detailed explanation-4: -A scientific theory is a hypothesis that has been extensively tested, evaluated by the scientific community, and is strongly supported. Theories often describe a large set of observations, and provide a cohesive explanation for those observations.
Detailed explanation-5: -In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. A theory is always backed by evidence; a hypothesis is only a suggested possible outcome, and is testable and falsifiable.
