A hypothesis is useful in science when it can be tested and when it can be proven incorrect. Hypotheses are proposed explanations for scientific phenomena or observations, and they need to be tested through experiments or observations to determine if they are accurate. If a hypothesis can be tested and proven incorrect through experimentation or observation, it helps scientists refine their understanding of the phenomenon being studied. It is important to note that a hypothesis does not need to already have an explanation or be proven correct to be useful in science. The main focus is on testing and refining our understanding of the natural world.
