RESEARCH METHODOLOGY

Detailed explanation-1: -As additional scientific evidence is gathered, a scientific theory may be modified and ultimately rejected if it cannot be made to fit the new findings; in such circumstances, a more accurate theory is then required.

Detailed explanation-2: -Theories can, indeed, be facts. Theories can change, but it is a long and difficult process. In order for a theory to change, there must be many observations or pieces of evidence that the theory cannot explain. Theories are not guesses.

Detailed explanation-3: -Scientific theories can be changed when new experimental evidence disproves aspects of a theory. All theories are built based on current knowledge and new information can overturn aspects of a theory.

Detailed explanation-4: -Theories may change, or the way that they are interpreted may change, but the facts themselves don’t change. Tanner likens theories to a basket in which scientists keep facts and observations that they find. The shape of that basket may change as the scientists learn more and include more facts.

Detailed explanation-5: -Answer and Explanation: A scientific law can absolutely be changed. A great example is Newton’s laws of motion.
