FTA: This work is just a start. The fact that all this emerges already from the interaction of just three particles is due to the beautiful simplicity of Newton’s law of gravity and certain architectonic structures it possesses. Einstein’s general relativity has them too but is a much richer theory, so we cannot say yet whether in that case law alone will suffice to create an arrow of time without the crutch of a special initial condition. If it does, though, one of the intuitions that most people, including many scientists, find very hard to shed—that time is real and does flow—may well be an illusion.
