1.11.24 Quantum Immortality and Suicide

quantum immortality has been one of my favorite quantum theories for a long time. i haven't found a lot of easy to understand explanations for idiots like me, so here i will try to explain! below is a little picture i made to help..

what happens in quantum immortality is: when your in a near-death experience, your conciousness swaps to another universe.. actually, i'm having trouble explaining it correctly while easy to get for dummies like me and you. so when you almost die, you DID die, but in the universe you did the act that killed you did. and this cycle keeps going and going, till your conciousness is ready to die/move on. so picture this: someone you know died here in this universe..but they're actually still living in another, thus quantum *immortality*.

a lot of people don't like to hear this theory because it's not very fun to think that people are mourning your loss in another universe..but remember, it's just a theory! it's only real if you believe it is. you're the main character to yourself so if you don't believe it..it's nothing! and for if you do believe it's real, like i said last paragraph (or mentioned) if someone you love dies, they're still alive and (hopefully) thriving..just in a new universe, which is fun to think about for me.

now, the quantum suicide thought experiment has a 50/50 chance of survival..so it's a pretty risky gamble! so, your the experimenter in this point of view! you sit before a gun facing your head..a gun that is rigged to a machine that measures the spin of a quantum particle! or..quark which is a funny name. when the trigger is pulled, the spin of the quark is measured. trust me, i don't get these long words either. depending on the measurement, the gun will shoot you in the head or it wont. spinning clockwise: it will fire - counterclockwise: lucky you..it wont.

so..you pull the trigger! but nothing happens..so feeling high and might, you pull it again. feeling like a god at russian roulette, wishing you were playing a match right now..you keep shooting and shooting and you dont die! you think your immortal dont you? your noooooot! because going back to the very beginning..you shoot yourself again and...your dead!..just in that last universe. your both alive and dead, the universes just split into 2. 1 outcome has you dead, another has you alive. so great job, your seen as a guy who thought he was immortal in like 10 universes...and only seen as the guy whos really immortal and feared by the bulletin in this one! so dont feel powerful and go grab that gun in the real world..there's still people who wouldnt wanna see that in any universe!

this (quantum suicide) can be related to Schrodingers cat. schrodingers cat is a thought experiment where (in easy words) put a cat under a box, give it some poison and..you don't know if it's dead of alive because it's not observed! ok, i don't like thinking of it like that only because it's a cat. how about a cockroach? schrodingers roach from now on! alright..in longer words, a cat, flask of posion, and something radioactive are all put under a box. if a radiation moniter detects radioactivity, the flask was broken and the roach is killed. The Copenhagen interpretation implies that the roach is simultaneously alive and dead. when you look inside the box, you see *either* a dead or alive roach, instead of a *both* dead or alive roach.

the schrodingers cat (or for you and me, roach) experiment asks how long quantum superpositions last and when or if they collapse.
