This is a misunderstanding of quantum mechanics.

The idea that the universe is “not locally real” suggests that particles don’t have definite properties until they are measured, with their states potentially correlated over distances through quantum entanglement. This doesn’t mean that only observed things exist; rather, it indicates that certain properties are simply indeterminate until measurement (or “observation”)

In quantum mechanics, “observation” refers to the interaction that causes a system’s wave function to collapse from multiple potential states into one actual state. This process affects the state of the system but does not imply that reality is created solely by observation, nor does it require a sentient observer
