I'm not sure what you are saying here. Are you invoking something like
Zeno's Paradox, which purports to show that motion is impossible? If you
believe in observers and in moments (even if they are the "block universe"
kind of moments), then you believe in observer moments. The main utility of
the idea, as I see it, is to eliminate ambiguity when the issue of personal
identity arises. If two or more related observers are separated in time,
space, parallel universes, substrate of implementation or any combination of
these, are they the same person or are they different people? It seems that
there are as many different answers to this question as there are posters on
this list, but at least if we specify our answers in terms of the smallest
possible unit of observerhood - the OM - we are able to communicate with a
minimum of ambiguity.
Adopting the term OM does not necessarily commit you to a particular
philosophical view, and it certainly doesn't mean that our brains generate
neat little self-contained parcels of conscious experience. Where and when
one OM starts and ends need not be specified, and probably can't be reliably
specified. I would say, very loosely, that if I become aware of any
subjective change in any parameter, then that is a new OM. I would guess
this would take between 0.1 and 0.5 seconds.

I do not understand what is meant by "Observer Moment" [OM].
I went back and found the very first post that contains such a reference.
It was by Nick Bostrom and is at:
The language in this post indicates that various processes take place
during an OM.
Quoting a small part of the post:
that your present observer-moment is at time 0 gives you reason
(because of Bayes' theorem) to prefer a hypothesis according to which
a larger fraction of all observer-moments are at time 0 to a
hypothesis according to which a smaller fraction of all
observer-moments are at that time. In the present example, that means
that finding yourself at t=0, you should conclude that the chance
that both coins will land heads is less than 1/4. This also means
that the chance of the first coin landing heads is less than 1/2.
Here we see processes such as discovery, preferring, and concluding taking
place within a moment.
This remains common in the language surrounding the idea of OM in the
current threads. See for example Stephen Paul King 's composite post
raising similar questions at:
Where various authors use processes within an OM such as reference to a
memory and thinking.
All this is confusing. How can a process take place within a single
In my view [compressed] is that all possible states of universes preexist
[perhaps compressed as interpretable numbers]. The system imbedding these
states has a dynamic arising out of the incompleteness of some of its
components which randomly provides these states with an instantation of
"reality" [being] of indeterminate dimensions. This will give rise to very
long strings of states given such being such that the succession of states
within the string can be compressed into a few simple rules [such as this
string?]. There is no "observation" in this dynamic, but rather just a
"flow" [not necessarily steady] of being.
