time reversal symmetry and entropy

Time reversal symmetry is a fundamental principle in physics stating that the laws of physics hold true even if time is reversed. It means that a physical process can proceed equally in both the forward and backward directions of time, implying that the future and past are indistinguishable. Entropy, on the other hand, measures the degree of disorder or randomness in a system. It is a concept from thermodynamics that characterizes the dispersal of energy or the availability of useful energy. The more disordered a system is, the higher its entropy. Entropy tends to increase over time, indicating a natural tendency towards a more chaotic state.
