How can there be an "afterlife" is conciousness is eternal? "After" what?
Again, say there's an afterlife. Say there's something beyond this realm. That still doesn't in any way point to a sentient creator.
Something had to create individual conscious entities.
You may reject this notion, but it is the only rational explanation for the existence of an external consciousness.

Citing the theory itself is not speculation. I'm not speculating about anything.

No, you do not need an observer to collapse a wave function. You need something that influences the experiment in such a way that the wave function collapses.
Your argument is along the lines of "If a tree falls in a forest and no one is around to hear it, does it make a sound?" with a difference topping.
Citing the theory itself is not speculation. I'm not speculating about anything.
I am going to make a speculative prediction as to the answer to this plb:
No but, yes but, no but, yes but and so on....:-)
In that case you are not speculating yourself, but what it is you are posting is mere speculation.

The idea that consciousness is the culmination of the interaction of simple systems into ever increasingly complex ones seems a beguiling one, and one which is scientifically testable. Alternative theories on sentience and consciousness are fine, but they need to be shaped in a way in which they can be proved or disproved, theoretically or otherwise. Not proved or disproved, just potentially so. Else it's just getting your brain's cock out and fatting everywhere.
Your earlier point on the complexity of the brain is false. If you consider than a single neuron is either switched on or off then there are more potential electrical states of the human brain than there are atoms in the universe.
If the mind were separate from the brain, why does intelligence increase, and behaviour become progressively more sophisticated as brain size increases?
It seems to me that you are terrified of the notion that we are all alone in the universe. You should be, it is! If the idea of a ubiquitous intelligence passifies you then go for it, but if you don't have anything tangible to back it up then don't expect anyone to take it seriously, and don't insult anyone who offers a contrary point of view - it makes you sound like a creationist.

I was with you, until you made the leap that somehow infinite conciousness translated into a sentient god, and managed to make this an atheists vs. theists thing.
How do you make the jump from endless conciousness to a confirmed existence of a creator?
If consciousness is infinite and eternal, then there is an afterlife. This non-local consciousness implies a creator to bring consciousness into existence in the first place in its non-local location.
I would also suggest that a Big Bang type event also implies the existence of a creator to bring that into existence as well, but physicists like to dispute this point by using QM interpretations. Obviously by refuting QM as a mechanism, I am demonstrating the need for a creator.

The probabilistic, non-unitary, non-local, discontinuous change brought about by observation and measurement.
OR
The deterministic, unitary, continuous time evolution of an isolated system that obeys Schrödinger's equation (or nowadays some relativistic, local equivalent, i.e. Dirac's equation).

So on what exactly do you base the assertion that a consciousness is required in order to make a wave function collapse?

Are you saying that this does not happen in nature at all? I would like you to support that assertion.

I don't assert anything. QM asserts consciousness is either necessary for collapse or the entire universe is purely deterministic.

I don't say anything. QM says collapse is necessary for matter to exist as it does.
I personally do not subscribe to QM's theory. What I believe is irrelevant to the discussion.

This is the many worlds interpretation which was addressed in the OP. But your attempt to dismiss the observer by equipment brings up an obvious error on your part, the fact that a conscious entity is required to build such observational equipment in the first place. Detectors did not exist prior to matter, therefore you are arguing yourself into a circle.
As was laid out by John von Neumann, there are only two processes of wave function change:

There is no speculation on my part. According to QM, consciousness either existed prior to matter or the universe is entirely deterministic and without free will. There are no other possible outcomes if one accepts QM as truth.

Well..., no, that is not what QM asserts. That is what you assert. But this conversation is going nowhere.

Nope. There are many more possible interpretations, some of them are both indeterministic AND consciousness is not necessary to cause collapse. There is a nice comparison on Wikipedia:
en.wikipedia.org...
Search for Deterministic:None and Observer role:None.
I personally prefer the de Broglie-Bohm interpretation. But of course, all are experimentally indistinguishable.
"This theory is deterministic. Most (but not all) variants of this theory that support special relativity require a preferred frame. Variants which include spin and curved spaces are known. It can be modified to include quantum field theory. Bell's theorem was inspired by Bell's discovery of the work of David Bohm and his subsequent wondering if the obvious non-locality of the theory could be eliminated.
...
In de Broglie–Bohm theory, there is always a matter of fact about the position and momentum of a particle. Each particle has a well-defined trajectory. "
The de Broglie–Bohm theory is an example of a hidden variables theory. Bohm originally hoped that hidden variables could provide a local, causal, objective description that would resolve or eliminate many of the paradoxes of quantum mechanics, such as Schrödinger's cat, the measurement problem and the collapse of the wavefunction. However, Bell's theorem complicates this hope, as it demonstrates that there can be no local hidden variable theory that is compatible with the predictions of quantum mechanics. The Bohmian interpretation is causal but not local.

Also note that only one interpretation infers consciousness and "but remains a view held by very few physicists". For good reason of course.edit on 20-1-2012 by -PLB- because: (no reason given)
According to a poll at a Quantum Mechanics workshop in 1997,[10] the Copenhagen interpretation is the most widely-accepted specific interpretation of quantum mechanics, followed by the many-worlds interpretation.[11] Although current trends show substantial competition from alternative interpretations, throughout much of the twentieth century the Copenhagen interpretation had strong acceptance among physicists. Astrophysicist and science writer John Gribbin describes it as having fallen from primacy after the 1980s.[12]
The Copenhagen interpretation is the "standard" interpretation of quantum mechanics formulated by Niels Bohr and Werner Heisenberg while collaborating in Copenhagen around 1927. Bohr and Heisenberg extended the probabilistic interpretation of the wavefunction proposed originally by Max Born. The Copenhagen interpretation rejects questions like "where was the particle before I measured its position?" as meaningless. The measurement process randomly picks out exactly one of the many possibilities allowed for by the state's wave function in a manner consistent with the well-defined probabilities that are assigned to each possible state. According to the interpretation, the interaction of an observer or apparatus that is external to the quantum system is the cause of wave function collapse, thus according to Heisenberg "reality is in the observations, not in the electron".[8]
