In this study, I argue that the future is not open if quantum mechanics is complete. An open future means that the value observed when measuring a physical quantity in the future is not determined. At first glance, quantum mechanics seems to support the open future thesis, because it cannot always predict measurement value with certainty. However, many interpretations regard quantum mechanics as deterministic. These interpretations only suggest that the quantum mechanical world can be deterministic. I argue that, although quantum mechanics cannot predict the future with certainty, the quantum mechanical world must bedeterministic, and the value observed by the observer is determined. I examine the following two cases: (1) the wave-function completely describes the physical state and (2) the wave-function does not describe the physical state. Then, I argue that the future cannot be open in either case when quantum mechanics is complete.References
