True, but the scientific community uses hypothesis in a different way to the rest of us. You are thinking of 'hypothesis' = 'theory'. this is not so in scientific use. A hypothesis is a theory that has been taken and tested and challenged. By the time it is presented as a hypothesis, basically it is what science considers to be true. However, science will never state that anything is 100% definitely true - it can only say that something is true as far as we understand it today. Every piece of scientific knowledge and every scientific fact is called a hypothesis by scientists. Even the fact that the planets orbit the sun is called a scientific hypothesis. It's just scientific terminology. It in no way suggests that it is not accepted as truth by science.
