Processes in particle physics demonstrate arrow of time
Macroscopic processes are usually not completely reversible: you can’t unmix or unbake cake, and perfume released from a bottle won’t spontaneously recollect. However, these phenomena involve huge numbers of particles. On the level of individual particles in elementary physics, the direction of time doesn’t matter to the forces involved. The exception to this is the…
