Quantum Immortality

[FoolClimax]

Probably the most scariest concept that no matter what ever you do you will always be conscious. You can't die. Your consciousness will transfer to a universe where you are still alive.
Out of infinite universes there's always one where your body is not dead maybe close to death but not fully dead.

I'd love to be conscious forever, just not in this self.

Horrifying idea

 

[eclosion]

Yeah, this reality we live in is an unknown.
There is a very real possibility that our suffering will never end, maybe the destiny of all humans is an hellish afterlife

If there were a multiverse, why my consciousness doesn't feel like living in more than one universe?

 

[Gustav Hartmann]

For me multiverses are in conflict with Ockham's Razor. But at quantum level there is supposedly a conservation of information, like the conservation of energy or momentum. As the macroscopic world is a result of the microscopic world and consciousness is basically information it could be that there is something like the conservation of consciousness.

Why don't the majority of us remember past lives then? Do you feel many millions of years old? Even if it does happen- it would seem like our memories/ consciousness resets at each incarnation. So- will future 'you' be anymore 'you' than the (possibly) millions of past 'yous' there have been?

Plus- if we really are 'us' as in- we are reborn to the same parents- how do our timelines align? The sequence is all off just in my family. My Grandad died first, then my Mum, then my Nana- 7 years after my Mum. What is my Mum and Grandad's spirits/ consciousness doing while it waits for my Nan to die and be reborn in this other world?

If we are born to different parents then- we aren't even 'us' anymore. We would have totally different genes, could be a different gender, different nationality, different species maybe. I suppose it depends on what you define as being 'you'.

My argument against quantum immortality, assuming the pop science version of many-worlds interpretation does hold, is as follows:

It's possible to observe yourself in a universe where you'll certainly die. When a person is decapitated, or a person's heart is destroyed (think: heart ripped out of your body Mortal Kombat-style), consciousness does persist for a few seconds. In those situations, you're in a position of essentially certain death while remaining some level of consciousness. Any parallel universe version of yourself that survives cannot be identical to one where you're already experienced decapitation and know you're dead, thus they can be treated as separate beings/consciousnesses. If there is a universe where you could be revived, it's not this one.

Therefore, I believe that you can die even if the pop science version of many worlds ("there is a universe for every possible action we do") is true. Once you die, your consciousness is either terminated or "goes somewhere else". The latter option might be scary, but who knows where and when? You could be revived a century later, or simulated in the future millions of years later. You could have your consciousness transferred to another person from any time/location/universe. Your brain could be reconstructed in the boundless years after the heat death of this universe. Or you could end up in any possible depiction of the afterlife, since none of this is falsifiable. For all you know, in your new body you'll find existence worth suffering for.

----

For uncertain means of death, like getting shot or dying of disease at old age, it's trickier. But A. you can die despite "needing" to witness yourself dying, and B. either it's possible for your consciousness to be terminated for good, or for consciousness to be transferred elsewhere after death (where the end result is completely unknown). So I believe it's possible to end our current existence as we know it, which is enough for me.

If you take enough lsd, you can experience different consciousness and different realities. One time on lsd, I felt like I was experiencing many different realities at the same time. I felt like I was the entire universe and could feel the interconnectedness of everything.
