    It’s actually an infinitesimal chance per subatomic particle, so if it does happen it’s actually more likely you’ll only be partway through the wall before your luck runs out.

    And if that weren’t existential dread enough, the same applies to walking on floors.

    Floating in space seems safe right about now.

    … except that quantum tunnelling can happen without anything in the way. Any one or more of the particles that make up a person can spontaneously resolve its wave function elsewhere in the universe.

    But the odds of any of this happening, especially in a massive object with interlinked wave functions, are so close to zero they might as well be.

      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!
