  • Quantum Tunnelling has nothing to do with passing through physical barriers, it refers to a spontaneous change in energy state which a particle should not be able to do due to insufficient energy.

    Think of it like a ball spontaneously borrowing energy to roll up a hill. When it gets over the hill, it will roll down far enough to repay the energy cost of it getting up the hill. But it still shouldn’t be possible!
