"But of course, the theory also raises a lot of disturbing questions. To name just a few,
1 What is this Y thing anyway? What does it mean to say that "probability waves" are flying through space, interfering with each other, and suddenly "collapsing" into definitenesses?
2 What does it mean to "measure" it? Presumably the photon is bumping into, and interacting with, all kinds of things on the way to the cardboard, but they apparently don't count as "measurements." At the same time, a measurement doesn't need to involve a person; you can stick a measuring device at one of the slits and never have a human being look at it, and the interference pattern on the back wall still disappears. So what is good enough to count as a "measurement"?
3 When you put a measuring device on one slit, how does the wave going through the other slit "know" that it's supposed to collapse?

Isn't there some possible explanation that corresponds equally well to all the data, but makes more sense than this nonsense?
The first three questions are really unanswered, although some work has been done on the second one.
The fourth seems to be "no." There are actually a number of explanations which are very different from the Copenhagen interpretation, but all of them are just as bizarre and unintuitive, in their own ways.
There seems to be no way to square these results with our intuition, or "make sense of them."
Y este probabilitatea ca un foton sa se afle intr-un anumit loc.
