Story summary

Researchers at the University of Surrey have made a groundbreaking discovery: quantum systems maintain time-reversal symmetry, functioning seamlessly in both directions. This revelation challenges the long-held belief that the Markov approximation disrupts this symmetry, hinting that the illusion of time's unidirectional flow may stem from how particles collectively behave, rather than from the laws of physics themselves.
