Quantum physics says goodbye to reality

Quantum physics says goodbye to reality

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 old models and concepts will have to go as we develop new and more accurate models of reality. Just because we don't understand how it all works right now doesn't give any more credibility to new-age hucksters' claims that nothing is real or can be known. Watch them try, though!
