Rules:

  • The messages can go as far back as the beginning of the 7 day period (the moment you found out about your assassin is after you)
  • You can only send the messages if you have cell signal (maybe don’t hide in the woods, you assassin might be there, and you don’t get a do-over 🙃)
  • Your phone is immune to damage and malware (although spyware and keyloggers can still be on there, but they can’t affect the system, just on “read only” mode). Auto-updates are now disabled by default
  • If assassin got your phone, they could send false messages to trick your past self. (Don’t lose your phone!)
  • At the end of 7 days, the Assassin will just drop dead due to time travel limitations, time travelers cannot survive longer than 7 days in the past (yes, the assassin is a time traveler 😉)

    I’ll try to send text to the very beginning of the seven-day period, sending each message on two-hour intervals sent to the point in time one second after the last message.

    Let’s assume that the seven-day period starts on 2025-05-12 08:00:00.

    • The first message will be sent two hours after the seven day period starts, and every two hours thereafter. This first message will be sent on 2025-05-12 10:00:00 and will include:

      1. the timespace-stamp of when and where the message is sent. the time part of this would be written in way that only I can encode and decipher.
      2. all the rules as I understand it so far
      3. what I’ve done from the the start of the seven-day period.
      4. something only I know that will convince myself that I indeed sent the message from the future
    • The messages will be sent to the time one second after the previous message was sent. Hence, continuing the example, the next message would be sent on 2025-05-12 12:00:00 to 2025-05-12 08:00:02, and so on.

    • The messages will follow the same format as the first one:

      1. timespace-stamp (when and where I sent the message from), the time portion written in the same code as the first one.
      2. any updates to my knowledge of the rules
      3. where I’ve been and what I did since the last message
      4. something only I know, and will reassure myself that the message is indeed from me
    • If for some reason I am unable to send any messages (for example, I have been asleep, or out of network coverage area) when I should (two hours have passed since the last message), I will send a message immediately when I’m able. This message will be sent to the time one second after the last sent message. So continuing the example, if the last message was sent on 2025-05-12 22:00:00, to 2025-05-12 08:00:07, and I’m asleep until 2025-05-13 09:00:00, I will immediately send a message to 2025-05-12 08:00:08.

    With this, assuming I survive for seven days (exactly) and stay awake the entire time, I will receive the last message before 2025-05-12 08:01:24. The timestamps of the last message will also give me a good indication if I survived the seven days, or how long I survived. If I continue receiving messages past that, maybe my future self messed up, or there’s something more going on, or my future self just decided it’s a good idea to just continue. Nevertheless, I have advance notice of what happens to me.

    Of course I will try not to lose my phone. With advance notice, I will try to stay as safe as possible without deviating much from the timeline. Also, I will try to figure out what’s going on, but only up to the point that I can keep myself safe.

    Every hour send a message back to the start of the 7 day period + 1 second for each elapsed hour “still alive at <current time>” At the first one hour mark send a message to three minutes after the start of the period. 168 hours in a week, texts with survival status will be done a bit before the three minute mark of constant messages. This message describes the situation. Now I have insight into when the assassin will get me, to an hour. Don’t change my behavior until the hour span leading up to the last still alive message, go nuts traveling randomly during that time until the number of still alive text messages changes After surviving for a week send a final message back in time to the very start “your phone is trying to kill you”

    But how does that help? If I send past me a message, can past me change anything? What happens to the me that sent the message if past me receives it and changes stuff? Seems like you’re creating a classic time travel paradox.

    “Oh, a text from future me? Let’s see what it says…”

    “FM: Ninja assassins are after you. You know what you must do.”

    shuts off phone nods solemnly “Set myself on fire.”

    What time travel rules? See: https://tvtropes.org/pmwiki/pmwiki.php/Main/TemporalMutability

    Going with “overwriting the timeline,”

    • buy yourself an hour to live on the first day, should be easy enough

    • make fat cash with options trading in minutes

    • buy hella security

    • repeat until the seven days have passed

    I would also rig a “dead man’s switch” on my phone in case the assassin ever does get me, to reset things (by telling my past self of my current situation, so they can avoid it).

    I wouldn’t warn myself because I don’t want to get caught in a groundhog day, butter fly effect scenario.

      I mean, you could just give your self a limit.

      Add a “Iteration 1” to the first message, and the 2nd iteration of you should append the message with “Iteration 2” and so on…

      If you still get warned of death in Iteration 500, then maybe then you can give up.

      At least try to survive for a few timelines.

        I would’ve created 500 alternative timelines by then, and in all of them my peers would have to live through my death. It sounds selfish to put that burden on them for the chance of creating one timeline where we maybe live happy, instead of just accepting my fate and leave only one family behind.

        I might tell myself that it’s really important to live the next seven days if they were my last.

        Playing with time doesnt sound wise to me.
