Quantum physics says goodbye to reality

20 April 2007

Some physicists are uncomfortable with the idea that all individual quantum 
events are innately random. This is why many have proposed more complete 
theories, which suggest that events are at least partially governed by 
extra "hidden variables". Now physicists from Austria claim to have 
performed an experiment that rules out a broad class of hidden-variables 
theories that focus on realism -- giving the uneasy consequence that 
reality does not exist when we are not observing it (Nature 446 871).

Some 40 years ago the physicist John Bell predicted that many
