If an alien species produced memories using process involving an overall negative entropy change, would it have memories from our future? It would appear to us as though these alien memories were being destroyed with an overall positive entropy change (since in our perception every reaction increases the overall entropy of the universe) - but in the perception of the aliens the memories would be being formed with an overall negative entropy change. Memories of the future. A hypothetical example might be: imagine it were possible to form memories by substituting EDTA ligands with an arrangement of other ligands. This involves a very large negative entropy change. Is it possible given: a) Physics; b) Evolution?
