Physics and chemistry indicate various irreversible processes, while physics also proposes the theory of time reversible symmetry (T-symmetry). I suppose that evidence of irreversible processes indicates that T-symmetry is a limited phenomenon instead of a universal law, but I also suppose that proponents of T-symmetry have considered the facts of irreversible processes. I answer yes to my question, but I want to learn more about this.

Thermodynamic irreversibility is a different concept to T-symmetry. Thermodynamic irreversibility is in fact time reversible. – John Rennie Jun 23 '19 at 04:15

@John Rennie Could you please elaborate on this? I would be grateful if I could understand how thermodynamic irreversibility is in fact time reversible. I guess I am getting hung up on the semantics. For example, I read that microscopic reversibility is permitted by T-symmetry while all types are reactions are not reversible. – James Goetz Jun 23 '19 at 04:20

I think this has been discussed already. I'm just searching the site to see it there is a duplicate question. – John Rennie Jun 23 '19 at 04:25

Alternatively we could discuss it in the chat room. – John Rennie Jun 23 '19 at 04:27
