"If one chooses to believe that the atom really did take a particular path or paths then one has to accept that a future measurement is affecting the atom's past, said Truscott."

Is that equivalent to "reality doesn't exist until it is measured"? Because I don't see the latter claim (which is the headline on HN) anywhere in the text?

Also, didn't Feynman explain in q.e.d. that it's not either a wave or a particle, it's always a particle and the probabilities for the path the particle takes behave like waves? (Something like that, I am foggy on the details).

Who or what is measuring all of the quantum building blocks that collectively sustain and comprise the total universe?

There is no reality at all, like 3D cgi, if no man see it, it will not be calculated, so no exists. It means another experiment: we living in a computer-simulation, http://www.telegraph.co.uk/news/science/science-news/1045198... http://www.huffingtonpost.co.uk/2012/10/11/physicists-may-ha... http://news.discovery.com/space/are-we-living-in-a-computer-... http://listverse.com/2013/12/02/10-reasons-life-may-be-a-com... http://io9.com/5799396/youre-living-in-a-computer-simulation... http://www.nature.com/news/simulations-back-up-theory-that-u... http://thelaymansanswerstoeverything.com/2013/01/scientific-...

For us, Reality by definition, is what we perceive. Our mind/brain/consciousness interprets the perceptions, draws conclusions makes up reality by interfacing an Electromagnetic medium. When trying to explain Popular Quantum Physics, one should avoid using the word Reality loosely.

I think most people's definition of reality would be precisely not that it "is what we perceive", in that two people can and often do perceive the same underlying reality differently. That there is an underlying reality at all may be an incorrect assumption, but it is the intuition most people have.

http://www.simulation-argument.com/simulation.html says: at least one of the following propositions is true: (1) the human species is very likely to go extinct before reaching a “posthuman” stage; (2) any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof); (3) we are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. A number of other consequences of this result are also discussed.

In the time of Empiricism, the philosophers George Berkeley and John Locke proposed something similar. I believe it was called it immaterialism, or the idea that nothing exists without being perceived. Berkeley went further saying that objects only exist in the mind, or something like that.

One of my favorite authors, Jorge Luis Borges, wrote a short story, "Tlön, Uqbar, Orbis Tertius," based on Berkeleyan philosophy. I thought again of this passage when I read the headline:

"Things duplicate themselves on Tlön; they also tend to grow vague or 'sketchy,' and to lose detail when they begin to be forgotten. The classic example is the doorway that continued to exist so long as a certain beggar frequented it, but which was lost to sight when he died. Sometimes a few birds, or a horse, have saved the ruins of an amphitheater."

In other words, reality is lazily evaluated and is written in Haskell ?

The press around this experiment uses misleading language that leads people like Deepak Chopra to think that we create reality through consciousness. It has nothing to do with consciousness. This article explains it:

Reality is just a giant whirling layer of infinite View Master-like multidimensional slides, overlaid one upon the other. Every slide locks into place to be seen as we are looking in whichever direction, at whatever time. I'd wager time travel is never discovered by humanity, but that some sort of time or dimensional goggles are created, eventually.

Essentially, we're all watching our own multi-dimensional, multilayer, composite TV channels and seeing shadows of each other across our screens. Allegory of the Cave meets 3D Ray Tracing and such.

That's nothing, though. Not compared to the realization that every face is a mirror, and we're all stuck here until we can treat each other as ourselves.

Maybe it's not true, maybe it's insane ramblings. But it does explain the crazy doods muttering to themselves on the corner and those people in your life who "just aren't watching the same channel as the rest of us."

Like me!
