#2This experiment has been posted to HN a few times in recent weeks, but I'm not sure it's had a real discussion yet.
The paper is at http://www.nature.com/nphys/journal/vaop/ncurrent/full/nphys.... We changed the URL of this submission from http://www.independent.co.uk/life-style/gadgets-and-tech/new....

#3What does it mean to exist? A thing exists specifically when it affects something else. What is measurement? It's a reciprocal affecting.
So does a thing which is not affecting anything else and not being measured exist? No! QED

#4We know that light bends near a
gravitational field with a big
gradient before it is "measured".
Sounds like that light existed and generated and responded to a gravitational field after it was emitted and before it was detected or measured.

#5This is of course extremely interesting and probably important for understanding our universe—but how is it helping anyone to say something like, "...with scientists performing a famous experiment and proving that reality does not exist until it is measured." The statement is like a distraction at a magic show, drawing the reader to the glittery 'reality' and 'exist,' which are totally undefined so the reader's imagination can rove without limit.
Maybe this is really just a fundamental challenge to our assumptions about motion of particles or information transfer in the universe. Isn't that interesting enough without these vague, human aggrandizing assertions about creating reality?

Reality is that which, when you stop measuring it, doesn’t cease to exist.

depends on what the meaning of "is" is....
