You know how a lot of us believe that the past can affect the present and/or future? Well, I was watching a recording of Through the Wormhole with Morgan Freeman (The episode is about Free Will) , and it was talking about physicists' perspectives and one of them believes that the future can reach back in time and affect the past (retrocausality), and not just the past affecting the present/future. So basically he believes that cause-and-effect isn't what we always thought it was, and he puts a quantum physics spin on it, which I cannot remember exactly how. Is there anyway you can justify what he means or what he could possibly mean? I don't get how the future affecting the present/past is possible. Maybe someone here can help me understand how it is.
