> it’s just that typically there are a lot more possible futures for the current state than pasts, because of entropy

You've either just read "The Order of Time" or you already know a bit about this field. I'm reading it at the moment, as a non-physicist.

Your statement above isn't clear to me. Could you simplify why "the future" has a lot more states than the past, because of entropy?

Isn't this circular?
