Full Idea
All our physical laws are time-symmetric, ...so things can run forwards or backwards. But entropy is an exception, saying that disorder increases over time. Many physicists therefore suspect that the flow of time is linked to entropy.
Gist of Idea
Entropy is the only time-asymmetric law, so time may be linked to entropy
