Hello guys, I have few questions about the well-known quantum tunneling. I'll start off with the animation from wikipedia So question #1 why doesn't the barrier collapse the wave function, is that even possible? What's the difference between the barrier and the measurement screen in double slit experiment which collapses it when the behavior of the particle is clearly similar (moving towards the object) Question #2: the wavefunction of any object has a small component on the other side of a barrier that it classically cannot pass. So for instance, theoretically, there's a non zero chance that some object from my room instantenously appears in the other room. What would happen with some object on the other side which before the tunneling act was in a location x which the tunneling objecg would occupy during the act of tunelling, how would the "spatial overlap" of those 2 objects be avoided? Thanks in advance.
