I have had many people claim that QM has never made a prediction that has been contradicted by experiment. Yet as i understand it Qm predicts the vacuum energy density is 10^122 erg per cubic cm whereas the measured energy density of 10^-8 erg per cubic cm. So how is that not an example of an experiment contradicting QM? of course Im aware that most people think there will be some modification to QM to correct this but who does one say theres no experimental evidence to contradict QM? It seems to me there clearly is, where have I gone wrong?
