If you subscribe to the theories of MWI/UDA, then the idea of quantum immortality/suicide follows (an observer only perceives universes where it continues to exist, so from its perspective it exists forever). From this, it follows that an observer can "program" the universe into any possible state with the following process: - Choose a condition for the universe (e.g. "It will start raining at my location within 10 seconds.") - Evaluate whether you are in a universe where the condition is true ("10 seconds have passed. Has it started raining?") - If the condition is false, stop existing (in a human context, suicide :/). - If the process was followed correctly (the condition was evaluated accurately) the observer should only exist in universes with the chosen state This relies on the assumption that there is a possible universe where the condition is true, and that the condition can be effectively evaluated. I'm not yet sure about what to think about conditions about past events. What happens if the chosen condition was "It started raining less than an hour ago."? This would possibly work as expected if you don't evaluate the condition until after you chose it (you were in a soundproof, windowless room for the last hour, so you didn't know it started raining until after you decided on the condition). Any thoughts? Or relevant material I should know about? Also, let me know if there's some huge flaw in my thinking. A possible flaw is that, if the holographic principle is true, that there are not nearly so many possible future states as you may suppose. What is "possible" in QM is not the same as "logically conceivable".I tend to suppose the HP shows we live in a multiverse, so the possibilities within a given volume are proportional to the volume of the volume, but the ones realised in our branch of the MV are proportional to the surface area of the volume. (But there is probably a flaw in my reasoning too...)
But it's only the ones that are continuations of one's current state that are possibilities, so they are bounded by the hubble sphere surface area - at most, there may be other tighter bounds too.
