This is conceptually similar to a Resurrection, changing from one physical status to another contrary to traditional laws of physics.
'''Quantum tunneling''' is ability of a particle to overcome a potential barrier, even though it does not have sufficient [[energy]] to do so. An example is an [[electron]] being fired at one side of a barrier and reappearing on the other side. The most common example is when the barrier is an insulator, and an electron on one side of the insulator moves to the other side. The term "tunneling" is a bit of a misnomer because the electron does not actually travel through the insulator (insulators do not conduct electricity). It reappears with the same energy it started with.

Quantum tunneling is important in [[radioactivity|radioactive decay]], when an unstable nucleus emits a particle, it utilizes quantum tunneling to do so.
