B Does retrocausality only apply to subatomic particles?

  1. Mar 23, 2016 #1
    It seems that historical events are the same every day. If the future affected the past wouldn't history books change everyday by themselves? Is it possible that history does actually change but we don't realize it because our memories change too?

    What do you mean by "retrocausality"? Can you give a mainstream reference (textbook or peer-reviewed paper) that describes the concept you are referring to?

    There are a great many things that are "possible", but in the sciences, we can only make real progress on questions that can be answered experimentally. How could you tell if the world worked this way?
    If there's no way of telling, then there is no way of knowing.

    That sounds right, other than the fact that retrocausality does not explain anything which ever has been observed.
