Abstract

It is argued that the initial state of the universe is neither a high-entropy equilibrium state nor a special low-entropy state, but a quantum superposition of high-entropy states and low-entropy states, and the sum of the squared amplitudes of the low-entropy states is most likely close to zero. In this case, the thermodynamic arrow of time in our universe can still be accounted for by the many-worlds interpretation of quantum mechanics. This provides a new solution to the puzzle of the arrow of time.
