Einstein's Bubble

If we wanted to understand this motivation and analogy using Einstein's bubble, how could we move this motivation to consider it's first expression, lies wihtin the bath of possibilties?

One needed to see this physics process in its whole harmonious view, to understand that even strings only tells us part of the story. If we disc the supersymmetrical reality, then how will you ever assume that this emergence had to come from some situation. That it is described by recognizing the pre-existing steps that will make this supersymmetrical reality possible for such expressions?

Afshar has done a variation of the standard two-pin-hole "welcher-Weg" optics experiment, in which he demonstrates that wave interference is present even when one is determining through which pinhole a photon passes. This result is in direct contradiction to Neils Bohr's Principle of Complementarity, which would require in the quantum world that when one is measuring particle properties [formerly read "measuring quantum properties" -KC], all wave interference phenomena must vanish. Afshar's trick is to find the location of the minimum points of wave interference, place one or more wires at these minimum points, and observe how much light is intercepted when one is determining the pinhole through which the photons passed.

I just wanted to add the following little blurb to show that the idea used here by John Cramer is one that many people like to use when we come to describing things if they contain others ways of describing?

Nathan Seiberg, a colleague of Witten's at the IAS, uses the analogy of blind men examining an elephant to explain the course of string theory until 1995. "One describes touching a leg, one describes touching a trunk, another describes the ears," he says. "They come up with different descriptions but they don't see the big picture. There is only one elephant and they describe different parts of it."The Guardian

So in this context John Cramer takes us through some information for consideration. This is also in context of the Welcher Weg experiment that is introduced on Lubos's site. Had he some search function I am sure he can take us directly to his continue discourse on this topic to help us orientate a better view of the issues. A little nudge again, like he's going to listen to what I have to say, eh?:)

The Blind Men and the Quantum: Adding Vision to the Quantum World

Question (Albert Einstein):

If a photon is detected at Detector A, how does the photon’s wave function Y at the location of Detectors B & C know that it should vanish?

Situation: A photon is emitted from an isotropic source. Its spherical wave function Y expands like an inflating bubble. It reaches a detector, and the Y bubble “pops” and disappears.
