Reason for time's arrow discovered?

Reason for time's arrow discovered?  One of the strangest unknowns in physics (and cosmology) has been the reason why time always progresses “forward”.  It seems obvious and self-evident to our senses, but it's not at all obvious and self-evident from the mathematics that underlies our understanding of physics.  Now scientists have some evidence that quantum entanglement is the cause of the one-way nature of time.  If so, it would make time's arrow the most obvious macro-scale manifestation of quantum physics...
