    you can easily return to the past

    but a tree used to be there where you are and now you’ve impaled it

      Well, if we follow that logic, then where you end up is the emptiness of space, even if you go back exactly one year.

      People tend to forget that the Earth not only goes around the sun, but the whole system is moving, so Earth is not in the same place as it was a year ago, even if it is relative to the sun.

        I think that brings up the question of how do we go about establishing an absolute position? If everything is moving, what isn’t?

        Everything being relative is a hell of a thing.
