I am not sure exactly what you explained. First off, relativity, like Newtonian mechanics, is a classical physics theory. I am not aware of any such thing as non-classical relativity. So why even say classical relativity? At the very least, it is redundant.

Second, of course the universe is probabilistic, a fact that falsifies both relativity and Newtonian physics.

Third, the universe is probabilistic precisely because time cannot change. Why? Because, since time is not a variable and is thus non-existent, the universe cannot calculate precise temporal durations. Thus, in order to properly conserve energy, it is forced to use the next best thing: probability.

Fourth, this has everything to do with article since entropy, as explained in the text books, assumes the passage of time and thus a time direction or arrow. Since time is abstract, it follows that an arrow of time is imaginary. As a result, it makes perfect sense that one cannot reverse entropy. Or anything else, for that matter.

The purpose of my comment was to get people to think and to stop accepting everything they hear on face value. If time cannot change, which is trivially shown to be true (changing time is an oxymoron because it is circular), then all the so-called time-travel conjectures by famous physicists like Kip Thorne, Stephen Hawking, David Deutsch, and many others, are pure crackpottery.
