Spudboy,
There is no observer in the usual sense of a human observer needed for quantum events.
But in effect every participant in a quantum event acts as an observer of that event.
In fact you don't even need any participants, not even instrumental ones:

P.S. Edgar, I notice that when you post a reply it includes your prior post, as though
you're replying to yourself (see below). But it doesn't include anyone else's comments,
which are actually what you're replying to. If you know how, it would be good to change
that so we could see what exactly you're replying to.
The theory of decoherence has rightfully superseded the old mistaken notion of an
observer 'causing' a wavefunction collapse, if that's what you are referring to.

To answer some of Jason's questions. Block time is wrong. Only the common
present
moment exists. All the comments Jason makes refer only to differences in
clock times
which are well known, but the important point is that all those differences
in clock
time occur in the SAME common present moment.. I find it difficult to
understand why
so many people can't get their minds around the difference which proves
there are
two distinct kinds of time.
The past exists only as inferences from the present as to what states would
have
resulted in the present according to the currently known laws of physics.
Therefore
the past is actually determined by the present state of reality from the
perspective
of the present which is the only valid perspective. Therefore the logical
network of
past and present is absolute 100% exact and could not have been different
in even
the slightest detail. The actual currently state of the universe falsifies
the very
possibility of other pasts. This is another difficult concept for many.
Only the future is probabilistic because it does not yet exist and has
never been
computed. But the past - present logical state has been actually computed
and thus
is completely deterministic now that it exists and it could not have been
different
in any minute detail at all.
This solves the problem of the original fine tuning. Given the current
state of
reality which is all that exists, all other conceivable fine tunings are
impossible.
This is what I call the 'Super Anthropic Principle', and it negates the
necessity
and probably the actuality of postulating any multiverses and strongly
implies our
observable universe is most probably the only one that exists.
