Pardon the interruption, but I need some quick clarification.(adsbygoogle = window.adsbygoogle || []).push({});

I was reading about decoherence, and QM, and trying to understand exactly what's going on, but I need to know if I have a grasp on the basic concept. In the double slit experiment, QM defines the probability that a particle will be found at a given location on the detector. But it is a misinterpretation of QM to say that the particle actually takes every path from emitter to detector. The wave function is a purely mathematical construct and not at all suggesting that the particle actually takes every path. Is this correct?

There is nothing that can be said about what is actually occurring during the period when the particle is between the emitter and the detector. Is this correct?

But there's another thing that I'm curious about. I assume then that String theory concerns the nature of the particle subsequent to the wave function collapse, and tells us nothing about the nature of any underlying structure. Is this correct?

If I have misinterpreted something is there a simple way to illustrate the connection between QM and M-theory?

Thanks
