<human>:  How does Carlo Rovelli explain the arrow of time in his book ‘Spoonbenders’?
<bot>: The arrow of time is the idea that time flows forward, and that the past is gone and the future is yet to come. This is a consequence of the second law of thermodynamics, which states that entropy in a closed system always increases. This means that the universe is becoming more disordered over time, and that the past is less likely to be repeated.
