But since you were defending Carroll, I'd still appreciate your own answers to my questions.-My point was that Carroll is using the concept of entropy correctly. I found this contradictory article which says entropy should not be used to define time. Time cannot be defined by physics and its formulas which can go it either direction with time and be correct. The concept of open and closed systems is what is correct for the 2nd Law. It was established over 100 years ago re' steam engines. Carroll is Delete repeated word correct Delete repeated word the universe is running down Delete repeated word its own destruction. If you wish read both articles to see the differences.
