It's a bit like symmetry breaking. You have an ensemble of all possible
observer moment, but each observer moment can only experience its own state.
So, the OM samples itself.
There exists an observer moment representing you at N seconds, at N + 4
seconds and at all possible other states. They all ''just exist'' in the
plenitude, as Stathis wrote. The OM representing you at N + 4 has the
memory of being the OM at N. Subjectively the OMs experience time evolution,
even though the plenitude itself doesn't have a time evolution at the
Although it is a bit strange to think about time evolution in this way, it
is necessary to resolve paradoxes you get when contemplating doubling and
suicide experiments. It is precisely in these cases that our naive notion of
time evolution breaks down.
