Tag: backcasting

In Sci-Fi, the Grandfather Paradox hypothesises that if one should travel into the past and change certain key events, the future will also be changed or even become unrecognisable. But what if we turn this hypothesis on its head, defining a desirable future and then reverse engineer the requisite actions to achieve this future? Unlike the Grandfather Paradox which, as far as we know, only lives in Sci-Fi movies and novels, backcasting is completely possible.
