By applying the Page and Wootters mechanism to two entangled but noninteracting theoretical quantum states — one a vibrating harmonic oscillator and the other a set of tiny magnets acting as a clock — the physicists found that their system could be perfectly described by the Schrödinger equation, which predicts the behavior of quantum objects. Yet, in place of time, their version of the famous equation ran according to the states of the tiny magnets acting as a clock.
