Quantum tunneling is a shimmering example of the microscopic world’s ability to surprise—particles which, in classical terms, should need sufficient energy to climb over a barrier instead have a real chance, by purely quantum laws, of appearing on the other side without ever going “over.” Their wave-like nature allows for some probability of being found beyond an obstacle even without enough energy for the task. Rather than absolute walls, reality sometimes offers doors made of pure chance.
