Answer
In science, a theory is much stronger than a theory in daily life. There are similarities. Both are educated guesses, in a sense. But in science, the educated guess has been tested over and over and over again. A scientific theory has many experiments and observations that have confirmed that it works to predict things and has stood the test of time. So in science, a theory is a well tested hypothesis where as in daily life, a theory is much closer to what we would call a hypothesis.
