what is the Copenhagen interpretation that also lead to Albert Einstein suggesting an idea that became Schroedinger's cat thought experiment later on in 1935?
According to the Copenhagen interpretation, physical systems generally do not have definite properties prior to being measured, and quantum mechanics can only predict the probability distribution of a given measurement's possible results. The act of measurement affects the system, causing the set of probabilities to reduce to only one of the possible values immediately after the measurement. This feature is known as wave function collapse
