Something I've for a long time been curious about is whether somebody has ever attempted to do a proper attempt at alternate history backwards? Every single timeline I've come across on this forum hitherto has either begun with a What If? asked regarding a specific historical even occurring in another way, or begun by stating a particular desired outcome, followed by a progression thereto from a chosen point in history.
However, I've never come across somebody trying to do the impossible, namely beginning by stating a scenario, and then trying to work out where the point of divergence was completely backwards. Deducing, figuring out or inventing the causes continually from the effect, in each step of the way.
Clearly this is very, very difficult, but as far as what human ingenuity has demonstrated to me so far, it shouldn't be possible. So, I'm wondering, has this ever been attempted at this forum, and if it hasn't, has anyone here ever thought about this as well?
