Maybe one of the issues here is the definition of measurement.
Most people would put an anthropomorphic meaning to this word. But I guess the masurement doesn't have to be observed by a human being to be a measurement, right?
Most particles in the universe are not being observed by conscious beings but I guess that if such particle in a state of superposition interacts with macroscopic object then it will get a definite state. Is this the interpretation of physicist?
It's so mind bending...
