What is the quantum observer effect?
Content: This led to a philosophy known as the Copenhagen school (after the great Dane, Niels Bohr) which states, to put it simply, that nothing happens until someone looks. If all we have are mathematical probabilities, then until the observation is made, we can only talk about probabilities. As to reality, we must give up hope of understanding it. “This was too much for Einstein and Schrödinger to swallow. Can it be that nothing really happens — that there are only probabilities — until someone looks? As Einstein lampooned, “Is the moon only there when we look at it?” “Einstein’s bomb. To show how ridiculous this view is, Einstein proposed the following thought-experiment. Imagine that a keg of gunpowder is triggered by the quantum instability of some particle. The quantum mechanical equation for this situation, he said “describes a sort of blend of not-yet and already-exploded systems… but in reality there is just no intermediary between exploded and not-exploded” ( I2007, p. 456 ).
