They must be testable and falsifiable. They should also be based on observations or facts, not random occurrences. The hypothesis that “there are no living beings in any other universe” is not correct because it cannot be tested. Another incorrect assumption would be: "The object in the box is magical and changes shape." This is neither testable nor falsifiable because of the word magic. At the end of the black box experiment, we were not allowed to open the box and see once and for all whether our assumptions about the shape or composition of the object were correct. based on the theory that we can never be one hundred percent sure of anything in science. We might even see and touch the object, but there is always the possibility that we might be wrong about what it is. Nothing is guaranteed. The black box experiment did a good job of showing us more about the steps in the scientific method regarding hypotheses. We had to formulate four hypotheses and then say whether we disproved one. This really led us to test our hypotheses to the best of our abilities with the limitations imposed on us by the box. Because of the scientific method, every scientist who performed the experiment had the same working structure. Even if it were different information, it would be easily interpreted and remade by anyone. This is what makes the scientific method so
