Main Question or Discussion Point
So I've been reading up on some quantum tunneling. It seems as though everything I read on it only conveys an elementary view on the matter, as if their target audience was the general public. I am here to gain a more sophisticated understanding of this concept. As I currently understand quantum tunneling is the effect of particles colliding at high speeds as to where the mechanical energy is greater than the potential energy of the barrier and in QM there is probability that the particle will appear on the other side regardless of the width of the object?! Why is there not a chance that the particle could appear inside the object? Has there been successful studies done on this? Does this constitute possibilities in teleportation/information sending?
