Why Is Quantum Tunneling Possible? The quantum tunneling effect is a quantum phenomenon which occurs when particles move through a barrier that, according to the theories of classical physics, should be impossible to move through. The barrier may be a physically impassable medium, such as an insulator or a vacuum, or a region of high

What Are The Chances Of Your Hand Going Through The Wall? In terms of whether your hand can pass through a wall, quantum theory says that it will never actually happen. The probability is technically non-zero but it is far too small to mean anything. What are the odds of quantum tunneling? … which is
