another physical arrow of time


"That revelation, which has been submitted for publication to Physical Review Letters, leaves no room for doubt: B-bars turn into B-minuses far faster than B-minuses turn into B-bars. As many as five B-minuses are produced for every B-bar. The chance of this result being a fluke is a nugatory one in 1043. Going forwards is thus not the same as going backwards, and time’s arrow really does exist."

Are there implications for blockworld/presentism?
