But to the bafflement of generations of physicists, the arrow of time does not seem to follow from the underlying laws of physics, which work the same going forward in time as in reverse.
Wrong - there are subtle differences on the particle level so for some things going forward in time doesn't happen in reverse if you go back in time - discovered in the 1980's.

There seems to be no connection with that microscopic event and entropy which is macroscopic or what we perceive as the "flow of time", but as more and more is learned about particle physics, who knows what they'll find.

This all awaits the impact of the delineation of gravity waves found by the south Pole telescope ( which possibly can travel faster than the speed of light) and the possibility that neutrinos can exceed the speed of light also thus being able to send us, or our view, back into time.

This is all off the top of my layman's head of course--would love to hear what if anything the entanglement physicists say about those issues.
