EVERYDAY SCIENCE

Detailed explanation-1: -Theory and principle are two inter-related concepts. The key difference between theory and principle is that theory is a scientifically credible general principle that explains a phenomenon whereas principle is a basic truth, rule, or law.

Detailed explanation-2: -A theory does not turn into a scientific law with the accumulation of new or better evidence. Remember, theories are explanations and laws are patterns that we see in large amounts of data that are often written as an equation. A theory will always remain a theory; A law will always remain a law.

Detailed explanation-3: -Principle theories serve as guides, or constraints, in theory development by setting parameters in the form of universal laws. For this purpose, principle theories are ideal, offering a firm foundation due to their generality and security of logical foundations.

Detailed explanation-4: -Although it may be entirely correct, the scientific community must agree with the hypothesis and back it up. Once the overwhelming majority of scientists agree with a hypothesis, meaning it has withstood the test of time and science, it becomes a theory.
