One could argue that as a proof-point towards the existence of a
God-entity; something whose sole raison d'etre is to be an outside
observer which permits all the waveforms of the universe to collapse to
particles. XD

One could, but one would be wrong. ;-)
Robert Sawyer has investigated that in a quite delightful novel called Starplex.

Why is that? You've heard of Heisenberg, haven't you? :)

Wrong? Qualitatively, it wouldn't be 'wrong' so much as
'unprovable'...either way. 'Wrong' is reserved for statements which are
*provably* untrue. 'Not provable'!='not right' or 'not wrong'

I would think you could prove that to be untrue, just like you can prove
there are no hidden variables.

My personal thought on the matter is that any single particle can be in
a quantum state, or you could do so in a condensate, but that, in normal
conditions, the vibrations introduced by thermal variance, and possibly
other sources of energy, introduce a situation where its no longer
possible for all particles to be in a single state. Once any one falls
out of a superposition state, its interaction with others causes *all*
of their quantum states to collapse into a specific state. After that,
since no single particle is ever, for any significant amount of time,
out of contact with other particles effects, they cannot return to an
unknown state. Now, if such state transitions where instantaneous, we
*would* have a problem. But, a recent experiment showed that they are
not. Basically, if it was instant, then you couldn't do something to a
particle, which collapsed its state, stop that state change part way,
and make it instead shift to a different one. You would never have
enough time to introduce the second change. However, the experiment
showed that, in fact, you "could" introduce such a second change, and
reverse the partial transition, which was already taking place.
So, no, an object, above absolute zero, can never reach superposition,
or any other quantum state, since its own particles will prevent such
transitions, via their constant interactions, none of which allow for
enough time to pass in which a state change could happen. In effect,
their proximity "locks" them in what ever state they are already in. To
change the state of one particle, you would have to induce a state
change in *all of them* at the same time, or at least a sufficient
number that they majority would impose their state, instead of reverting
to their prior state, via interface with the other, unchanged, particles.
It may also be a case that a large mass of particles will fall into
states that are stable, and that most quantum states, in such large
collections, are *not*.

I'm not even sure what that means, but since I can observe the effects of
quantum mechanical superpositions at the macroscopic scale (without even
having any sophisticated equipment) I find this an unlikely explanation.

You are forgiven; we'll file that as "random thermal noise" :-)
The thing that presently intrigues me most about the quantom world is
the question: Do probability waveforms really always /collapse/ when
particles interact - in the sense that the resulting effect is
/definite/ - or do they just "narrow down"?
That is, if for instance you do the double-slit experiment with single
particles, firing them at a photographic plate - will this really result
in a pattern of exposed spots on an otherwise non-exposed plate, or will
it rather result in a pattern of spots that are 99.99999% likely to be
exposd, on a plate otherwise 99.99999% likely to be non-exposed?
Or, to put it in other words: Is /fact/ something that actually
manifests whenever independent particles interact, or is it just an
illusion all throughout, and "independent" particles are merely just
"weakly entangled"?

First, you have Plank's uncertainty. Second, you have a lack of invariance
over scale, meaning your exposure of a particular "spot" on the film isn't
going to be smaller than an atom anyway.

That doesn't make sense. Either the spots are exposed, or they aren't. (Of
course, even exposed spots can spontaneously move around in the same way
that all the air in your room may spontaneously shoot up into one corner.)

I'm pretty sure that particles which have never interacted cannot be even
weakly entangled. But it takes more than a small number of particles
interacting to make something "fact" at the macroscopic level.
