This question already has an answer here:
Since the 2nd law of thermodynamics says the universe's entropy is constantly increasing, then its initial entropy must have been smaller than it is today.
However, no known physical law can reduce net entropy.
Does this mean the initial low entropy state of the universe must be the result of something that is outside the physical laws? Or does it mean there is a physical law that can reduce entropy?
The linked questions sound similar, since they also deal with the low entropy state at the beginning of the universe. But the questions are not asking whether this implies it was caused by something outside our physical laws, which seems the straightforward interpretation.
