Your comment is wrong. In the 3rd of the 3 interpretations of QM (Debroglie Bohm) this is exactly the case. The world is at all times in a well defined state. We just don't know it until we measure so we use probabilities to desceibe. All 3 QM interpretations are mathematically indistinguishable.
- akvadrako 9y agoThe point is a bit more subtle that than. Both WMI and Bohm's theory are deterministic, so the world is in a well-defined state. But any property we can measure is not well-defined, in the sense that before we have actually measured it, it doesn't exist.
