Detailed explanation-1: -Answer and Explanation: A scientific theory is not something that was “proven” right, it is merely a statement supported by valid experimental results and observations.
Detailed explanation-2: -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-3: -Even when a theory is accepted as fact, it remains a theory. While a scientific theory such as Isaac Newton’s theory of gravitation makes an infinite number of predictions, it can only be verified by a finite number of observations, so it can never be seen as irrefutably correct.
Detailed explanation-4: -A theory – just like a guess – may be true; equally well a theory may be false. This is not to say of course that any one theory may be both true and false. I mean simply that something’s being a theory does not preclude its being true: it may be, or then again, it may not be.
Detailed explanation-5: -A theory is a formal explanation of the relationship among a set of observations. The observations provide evidence for the theory. Pieces of evidence support a theory in the way that legs support a table or columns support the roof of a building. Scientists develop theories to explain natural phenomena.
