~~~~ we've come up with a _very tiny handful_ of ways to do time travel.
one of the ways to _simulate reality in a reversibly deterministic manner, fully predict the future, and run it backwards_.
is this sufficient for telling a friend goodbye after they left?
only if your friend is within the simulation, and you can control the simulation.
ohhhh and if the friend is also outside the simulation, it only works inside the simulation. outside the simulation it is more a complex and extremely obsessive expression of regret.
but some of the ways do work in reality! uhhhhhhhh _seem like they might_ work in reality if things that don't happen did happen (like mapping and generating life).
one of--
prerequisites for natural time travel: - understand time as nonlinear and bidirectional in a deep and thorough manner - encrypt a complete descrip--
no it is cool! this is cool: if we look closely at the uni--- oops. oops! anyway so, forgot to say goodbye to friend? you need to figure out the space of _potential life_ that exists in the _present moment_ that expanded from the bits of the past where you _basically did say goodbye_. think of this like a living spirit, or a robot, or a patch of sand or whatever. you map this thing in the future, and relate with it in such a way that the livingness of having said goodbye when you meant to expands as if you did. this is the same thing as teleporting the meaning into the past and having it happen, but it bypasses the creepy situation of changing the past or pretending that you did. people get confused when that happens. _extremely confused_. this means that you run after you friend and apologize for not saying goodbye earlier.
