FYI: In quantum mechanics, time may flow differently

At Eurekalert: As pointed out by Giulia Rubino, lead-author of the publication, “although time is often treated as a continuously increasing parameter, our study shows that the laws governing its flow in quantum mechanical contexts are much more complex. This may suggest that we need to rethink the way we represent this quantity in all those contexts where quantum laws play a crucial role.” Read More ›

Has a recent find brought us closer to understanding why time goes only one way?

Wolchover: The researchers have discovered simple, so-called “universal” laws governing the initial stages of change in a variety of systems consisting of many particles that are far from thermal equilibrium. Read More ›
