The realist interpretation of the Uncertainty principle posits that reality is independent of the mind of the observer, therefore all objects must objectively have a pre-existing value for any possible measurement before the measurement is made. But because of the combination state of a quantum event (Schrodinger’s cat being simultaneously dead and alive before observation) there can be no pre-existing value for a possible measurement before the measurement is made, therefore no "thing" has a predefined existence in an unobserved state, which contradicts Materialism and reduces it to absurdity, i.e.that all things are composed of material, and that all emergent phenomena are the result of material properties and interactions, reality consists entirely of physical matter that is the sole cause of every possible occurrence, *(which cannot be true, according to realism, if no "thing" has a predefined existence in an unobserved state).
So if the Realist interpretation of the Uncertainty principle reduces Materialism to absurdity, why is Materialism still central to Physics?
