    So, if I take my understanding of science and try to reason my way to conclusions about the nature of reality, I arrive at a surprising conclusion about life after death.
    I have been an athiest all my life and only started having these ideas about a science-based / non-spiritual afterlife a few months ago.
    I am cautious about accepting my own conclusion because I am aware that wishful thinking could have biased my reasoning, so I put it to you, the good people of The Science Forum, to try and poke holes in my logic.
    I'll try to lay out my reasoning as clearly as I can, don't hesitate to ask for clarification.

    So, my conclusion about an afterlife arises from two assumptions - that there is an infinite multiverse, and that reality is fundamentally nondeterministic / random (I'll justify these two assumptions in a bit).
    If there is indeed an infinite multiverse, then there must be a infinite number of parallel worlds (for each universe there is a small probability of it matching ours so exactly as to lead to a parallel earth and parallel versions of ourselves, but with infinite universes anything, no matter how small the probability, must exist). If there are infinite parallel worlds, and if reality is fundumentally random, then everything that can possibly happen from this moment onwards will happen. This leads, firstly, to multiworld immortality (you can google that term for more information), in which every time you die there is a parallel universe in which you didn't die so that your conciousness always continues.
    But my reasoning goes further. If your physical body ever reaches a point where it is so aged and decrepit that there is zero possibility of death being evaded, your body may well die, but your consciousness will continue at another point in spacetime. (This relies on the assumption that there is no soul and your consciousness is merely the pattern of neurons and synapses in your brain). If all you are is a pattern, then with an infinite multiverse, infinite existence, infinite arrangements of various things into various patterns, any pattern (including you, me, anyone and anything) will be replicated, no matter how complex the pattern or how unlikely its replication.
    Therefore, we will all live to the oldest possible age in our physical bodies, and then our consciousnesses will be randomly replicated at some other point in spacetime.

    Now my assumptions.

    Assumption one: there is an infinite multiverse. I believe in this because of the principle of uncertainty. I have read that the principle of uncertainty is essentially what results in existence. Zero is a constant value; at no point in spacetime can energy remain at a constant zero. This leads to fluctuations in energy resulting in virtual matter-antimatter pairs, which sometimes become separated and result in physically existing matter and antimatter. Given enough time/space/opportunities for these fluctuations to occur, eventually there will be a fluctuation so large that it results in a big bang. This is of course extremely unlikely to occur at any particular point in spacetime, but given enough opportunity, unlikely things will happen.
    What will happen after our universe ends, or after entropy has continued for so long that there is no longer any change and everything is in stasis? Will that be the end of everything? No, for that would defy the principle of uncertainty. Energy fluctuations will continue, and eventually there will be another big-bang scale fluctuation. Thus infinite universes exist, separated in either space, time, or both.

    Assumption two: reality is fundamentally random.
    It isn't logical for everything to be deterministic. Such a conclusion is inconsistent within itself. If something is deterministic, it must have a cause. If that cause is deterministic, it must also have a cause. Where is the original cause? What causes a radioactive particle to decay, and what causes that cause, and what causes that, and what causes that, on and on forever. Nothing could ever really be caused in a universe that is purely cause and effect, because any cause must itself have a cause and so cannot simply happen by itself. Therefore, the cause and effect that we see around us in our everyday lives must be an emergent behavior, caused by probability. In quantum physics, seemingly impossible things can happen - take tunneling for instance. But most of the time the more likely outcome happens, and particles stick to areas in which they are likely to be. This results in the large-scale cause and effect we are accustomed to: the root cause of the seemingly deterministic rules governing our universe is the fact that some quantum states are very likely to lead to other quantum states, and we hardly ever experience an unlikely transition.

    Sorry if a lot of this doesn't make sense, I'm kind of rambling - it can be difficult to translate thought into language. PLEASE feel free to point out anywhere I've gone wrong; the reason I've made this post is to attempt to disprove my idea. Also please feel free to ask for clarification on anything.

    Except that "multiworld immortality" is, basically, a flawed idea.

    But my reasoning goes further. If your physical body ever reaches a point where it is so aged and decrepit that there is zero possibility of death being evaded, your body may well die, but your consciousness will continue at another point in spacetime. (This relies on the assumption that there is no soul and your consciousness is merely the pattern of neurons and synapses in your brain).

    Therefore, we will all live to the oldest possible age in our physical bodies, and then our consciousnesses will be randomly replicated at some other point in spacetime.
    (At least) two problems here:
    1) "everything that can possibly happen from this moment onwards will happen" what if that replication can't happen?
    2) There's a difference between your consciousness being a pattern and you (qua you) being you. (2a: what would that pattern be in?)

    Given enough time/space/opportunities for these fluctuations to occur, eventually there will be a fluctuation so large that it results in a big bang.
    Citation needed.

    No, for that would defy the principle of uncertainty.
    Would it?

    Nothing could ever really be caused in a universe that is purely cause and effect, because any cause must itself have a cause and so cannot simply happen by itself.
    Unless, perhaps, cause and effect are due to the conditions of the universe as it is now (i.e. the "rules" were different at the "start").

    If I am replicated then I must also be a replica. I would think my exact replica would not live one nanosecond longer than me. If it does then how can it be my replica? My replica who lives longer will also affect the universe he lives in differently, no? (Butterfly effect?) But i guess even that gets replicated.If I have replicas that live beyond my years, then does that not leave me without any real purpose! Not that I think we have one.

    All that belongs to human understanding, in this deep ignorance and obscurity, is to be skeptical, or at least cautious; and not to admit of any hypothesis, whatsoever; much less, of any which is supported by no appearance of probability...Hume

    If your consciousness continues on after you die, then it must have been here before you were born, too, right? So where was it?

    Sorry, our consciousness is simply the product of our brain functions. It APPEARS to be something real, but it's just waves on the water. When the water disappears so do the waves.

    If a quantum fluctuation can produce something that's infinite then it seems to me that it must continue producting forever. Is there any evidence to support that the fluctuation is still going on? Can it be observed?
