From NewScientists 23 june 2007 "RealityCheck": [...] <<What they found(*) is that Leggett's formula is violated as well: even if you allow for instantaneous influences, quantum measurements do not fit with the idea of an objective reality. This is surprising because you might expect that, once any spooky "non-local" action is allowed, you could account for almost any relationship between two particles, and there would be no reason to ditch our concepts of reality. "This is not the case", says Aspelmeyer. Although some loopholes remain - not all non-local models have been ruled out - we now have to face the possibility that there is nothing inherently real about the properties of an object that we measure. In other words, measuring those properties is what brings them into existence. "Rather than passively observing it, we in fact create reality", says quantum researcher Vlatko Vedral of the university of Leeds, UK.>> (*) It refers to an experiment performed by Markus Aspelmeyer e Anton Zeilinger (Nature, vol 446, p 871) to test Leggett's formula (a variant of Bell's inequality, with the additional hypothesis that instantaneous inluences are allowed).
