[Verse 1] There's a wall that stands before you, solid brick and ten feet tall Classical physics says you're stuck there, can't get through it at all But in the quantum realm of tiny, particles don't play by rules They can slip right through the barrier like phantom dancing fools [Chorus] Tunnel through, tunnel through, when the wave don't fade away Probability finds a pathway where the classical can't stay At the Planck scale, Planck scale, where the quantum world takes hold Ten to minus thirty-five meters, that's where strange new stories unfold [Verse 2] Imagine throwing balls at concrete, bounce right back is what you'd see But shrink down to electrons dancing, they ghost through mysteriously The wave function doesn't vanish at the barrier's solid face It decays exponentially but continues through that space [Chorus] Tunnel through, tunnel through, when the wave don't fade away Probability finds a pathway where the classical can't stay At the Planck scale, Planck scale, where the quantum world takes hold Ten to minus thirty-five meters, that's where strange new stories unfold [Bridge] Alpha particles escape the nucleus though they shouldn't have the energy Scanning tunneling microscopes work by using this strange synergy When we reach the Planck length limit, space and time break down Gravity meets quantum mechanics in this smallest scale around [Verse 3] Every barrier has transparency if you're small enough to see The thicker walls mean less tunneling but never down to zero free At dimensions past describing, where our physics start to bend The Planck scale sets the boundary where known equations end [Chorus] Tunnel through, tunnel through, when the wave don't fade away Probability finds a pathway where the classical can't stay At the Planck scale, Planck scale, where the quantum world takes hold Ten to minus thirty-five meters, that's where strange new stories unfold [Outro] From the tunneling of particles to the smallest scale we know Quantum mechanics shows us worlds where only wavelike functions flow
