Entropy explained, with sheep (2016)
That still doesn’t answer the question how, if the laws of physics are time-symmetric, the universe as a whole can have a time-asymmetric evolution of entropy. I.e., if something forces entropy to increase in the long run, then that should hold in both directions of time. So what is it that causes entropy to only increase in the direction of the future, but not in the direction of the past, given that the laws pf physics do not distinguish between both directions?
