A scientific hypothesis is a statement which is based on the the direct observation of a scientific event, process or phenomena. It can be based on the assumptions. It is testified using appropriate scientific methodology.
The scientific hypothesis can be proved to be negative or false but repeated experimental trials can prove a hypothesis true and acceptable.
Hypotheses are supposed to be tested, to be proven correct. They usually start from a small thought without 100% correct, but as you do further testing, they become stronger.
