The answer is Theory.
Here is a possible comparison of a hypothesis and a theory in science: A hypothesis is basically an educated guess, where nothing has been tested yet, whereas a theory is a hypothesis that has been tested over and over, numerous times, with the same results.
The hypothesis which has been tested and verified repeatedly by tests is called theory.
A theory has been well tested using numerous experiments. A hypothesis has not been tested yet.
A scientific theory is a hypothesis that has been repeatedly tested and still seems to be valid. These theories are tested by using the scientific method.
No a theory is not the same as a hypothesis. a hypothesis is a opinion to something or your experiment. a hypothesis also has to be testable to be a hypothesis. a theory is something that has been tested several times and all the results have come out the same.
a proposition in science is usually called a hypothesis. If a hypothesis has been tested many times and shows consistent results that support the hypothesis, it can become a scientific theory.
