The arrow of time problem may have been solved by this Italian physicist.

One has to say that Quantum Mechanics applies to macroscopic systems. In this case correlations define information. No correlations, no information. The next step is to say that no decreasing entropy process is recorded, that is, these processes cannot be known. There are no records of them.

If entropy decreasing events are happening we wouldn't know. We only know of constant entropy (reversible), or increasing entropy (non-reversible) ones.

Information then is the keyword in this solution. Information is the set of records. No records, no information.
