No matter how likely your death is, there will always be a version of you that survives. At least according to one of the most bizarre interpretations of quantum mechanics, known as Quantum Immortality.
Can science prove that you are unkillable? And does this mean our reality is split into an endless number of copies?

    That proves that Duaa
    Can make u the lucky version of you.
    And our fate isn't really definite it can be changed if Allah wills.
    And there are definitely creatures who can see us, but we can't see them. Because we are in a different dimension than them but they still co_ exist with us in the same " reality".
    And most importantly what we think is " reality " isn't really "reality".
    It's only what god wants us to see.
    Remember the 2 electrons that move together and act the same when we look at them.
    It might seem crazy but they are simply ordered to move this way.
    I think. والله أعلم

    So wouldn't that mean the many worlds theory is not true because no one is immortal? If it was true, then even if you aren't immortal, someone else on this planet could be and they would be increasingly difficult to hide as time passes

    Probability doesn't really exist in physics.
    It usually just means we don't understand the reason or law well enough to predict it.

    The example with kicking an Elektron in the same way and position is unpredictable is wrong. Because we just don't have a good way to really affect, see and use it's position. Just like you can't predict a billiard ball. If the table is shaking and you don't know which way it goes in which Moment.

    I am either fully sold on Quantum immortality or I have been getting insanely lucky since less than 1 year old with many near death experiences. Some in particular beating the probable odds of survival

    A dream i saw a dream a dream that wouldn’t end over and over again i repeated and corrected every mistake but before i new it i lost count i died over 100 Million Times

    If more than one outcome was possible due to the nature of particle wave forms, very few outcomes would ensure that a 1:1 match of our conciousness would even survive a diverging timeline. Variability itself would affect not just the world around us, but also ourselves. The actionable magnitude of the impulses created by the neurons within our brain would be susceptible to the same variation. This means that all the mental processes responsible for the thoughts we conciously and subconciously perceive are vulnerable to change. The train of thought we're on and background proccesses involved will likely be different everything from a few seconds to a few minutes before whatever catastrophic event occurs that determines our fate.

    There is a very, very remote chance that there won't be enough variation in stimulus to break our then chain-of-thought; the mind, however, that experiences death will suffer it regardless. The very idea that we could even perceive that a variable-outcome event has occurred in real-life and somehow monitor the diverging concious paths afterwards is pure fantasy. Watching it go down via a simulation could be interesting, though.

    I know my question might seem underwhelming compared to other but, but i’d genuinely like to know if it absolutely has to be a nuke or could any other lethal weapon could be triggered the same way

    But how is that a definitively conclusive test? You could still just get really lucky, and survive 100 times in a row. It might be a really small chance but why would that grant you immortality, or prove anything at all?

    I mean technically the probability wave thing works to describe everything
    big stuff just has a very well defined boundary between 0% and 100% of being itself
    small stuff doesn't

    If an Electron is Everywhere at once Untill observed Can't you just run the experiment 1000 Times Then Take The PROBABILITY of where it gets stationary The most Thus giving us a "Point" to make Valid predictions at where the electron is most of the time 🤔

    🤔… it would be interesting to find out if through the randomness it still followed the rule of normal distribution or the "bell curve looking at the double split experiment it has a observable pattern that from a laments perspective makes it look like a normal distribution. Yes you get 80% in the kitchen and 20% in the livingroom but maybe that's only because you looked in the living room and not the yard on the other side of the kitchen. If you are firing electrons they can go through both slits at once therfore they are creating 'double' the potential points of… well "probability"! So your experiment may have just been accounting for half.
