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".
That's correct, but we assume usually "classical" quantum
mechanics. Then, even if GR digitalizes the access to futures, it
seems to me that QM will still provide the rooms for immortality
(not necessarily a good news). Then, in such reasoning, QM uses
comp, and comp by itself leads to many forms of immortalities, if I
can say.
But does comp lead to immortality from *every* state? Are there no
cul-de-sac worlds?
For the ideally correct machine, there is no cul-de-sac world *from
the first person point of view". The cul-de-sac world concerns the
finite things which evolves, in the 3p digital possibilities, it is
the world of the rational believer who needs to publish or perish, and
meets dead line. A paper is dead, when he get the last point, and is
published.
The "you" in the view of []p & p (first person, soul) and in the view
([]p & <>t, observable) and ([]p & p & <>t) are "immortal" in the
sense that they obey
[]p -> <>p.
Intuitively, death is not a first person experience, a subjective life
is an open set, and []p & p, that is the S4Grz modal logic, provides
an arithmetical interpretation of intuitionist logic.
Despite the antisymmetry, we recover symmetry of the atomic sigma_1
sentences, for the three "1p" hypostases: (Bp & p, Bp & Dt, Bp & p &
Dt). The comp "bottom" (the sigma_1 truth) admits an arithmetical
quantization.
