This was a new paper which was in pre-print that I had discussed with Bill S

Original paper: http://xxx.tau.ac.il/pdf/1402.3872v1.pdf

No media write up yet but it goes into the discussion of an older paper (Nature review of an older experiment : http://www.nature.com/nature/journal/v474/n7352/full/nature10119.html)

This has caused a bit of a stir because of the problem it perhaps says something about the concept of a multiverse depending on where you sit with QM. Anton Zeilinger's original work opened a question which many have now taken up.

Quote:
Here we report an experiment with single photonic qutrits, which provides evidence that no joint probability distribution describing the outcomes of all possible measurements—and, therefore, no non-contextual theory—can exist.


Quote:
Our results illustrate a deep incompatibility between quantum mechanics and classical physics that cannot in any way result from entanglement.


Probably for the layman look at Sean Carroll's simple 36 slideshow (http://www.slideshare.net/seanmcarroll/the-many-worlds-of-quantum-mechanics) in particular think about slide 34.

Expect a lot more to be said on this subject because as you would well imagine it upsets many a QM researcher, I am sitting on the fence on the issue as I think the traditional view still holds sway ... more data please ... but I do like controversial post titles smile

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
