... excerpt from this link that expresses the idea far better ...
This is the problem with philosophers. They extrapolate to extremes where the underlying phenomenon has no voice.
This is a gross misinterpretation and misuse of Heisenberg/Bohr and the Copenhagen Interpretation.
QM does not say that particles (or moons or suns or universes) do not exist until they are observed, but that the wide probabilities of a particle's states are its reality until specific values are observed (collapse of the wave function).
Feynman's Sum-Over-Histories is an excellent tool here. For any particle every possible state must be considered even though the probability of that possibility is vanishingly small. The probability sum of those possibilities is the reality of the particle. For single particles this probability function will be spread giving rise to Heisenberg's uncertainty in position-v-momentum or energy-v-time. As particles aggregate, however, the sums peak in sharper relief and the uncertainty becomes less to the point that the aggregated object mimics the certainty of classical mechanics (the correspondence principle of Copenhagen).
Whether there were eyes to see it or not, the moon, the sun, the universe (as an aggregate of particles) existed in a certain location at a certain time with a certain set of attributes.
This it ain't there till ya see it is bogus and any philosophy based on this is bogus.

I have to rely on what I read.

Here is a web site devoted to the theory.
Neither of these negates the bogus application of QM used as a basis for this bogus philosophy.

Double Trouble
not depending on whether someone is watching he slits
Things would be easier if this were true.
Both slits open. Detector ONLY on right slit, before right slit:
Detector off, interference pattern seen. Detector on, scatter pattern seen.
----------------------------------------
Move detector after slits but only on right slit. Same sequence, same result.
----------------------------------------
Use photons. Photons can be split into index photon (towards screen) and signal photon (90 deg. to index toward detector).
Detector off, interference pattern. Detector on, scatter pattern.
When the detector is off (not reading the signal photon) the index photon contributes to the the interference pattern.
When the signal photon is measured, the index photon results in scatter pattern.
----------------------------------------
Move the signal photon detector to 100 times the distance from slit to screen.
The index photon has reached the screen well before the signal photon has reached the detector.
Detector off, interference pattern. Detector on, scatter pattern.
How? Why?
----------------------------------------------
No time for specific references. They are on the web.
If you don't find them I'll look them up later. Work calls.

Re: Double Trouble
What needs to be determined is whether it is the detector or a conscious observer that makes the difference, To the best of my knowledge the evidence points to the detector.
So true.
That's what I get for being rushed and being unclear in my response.
What I was responding to was
Message 12
Specifically,
The "double slit" experiment shows particle-like behaviour when one slit is open and wave-like behaviour when both are open, not depending on whether someone is watching he slits.
Both slits are open and, depending on whether the detector is on/off the interference (wave) or scatter (particle) pattern are seen.
I do not know of any experiment attempting to separate detection from conscious observation.
I suspect the results will not change. IMO, it is the act of "detection" not "conscious observation" that breaks the interference pattern. A conscious mind does not appear to be necessary for the universe to exist ... or evolve.

Philosobabble.
This is the problem with philosophers, they take concepts far to the extreme and off into absurdity.
Quantum uncertainty yields a probabilistic universe. Combining millions of probability curves still mimics the certainty of Classical Mechanics in the aggregate.
By Linde's reasoning this universe could not be said to exist without a conscious observer to see it. But let me take this one logical step further, a step that Linde and others fail to take.
This universe cannot be said to exist without my personal observance. I, AZPaul3, am the center of the universe. Actually, the bridge of my nose is the center since no matter which direction I look the measure of distance as far out as it is possible to see is exactly the same. From the philosopher's own handbook, I cannot say the universe existed before I, personally, was here to observe it. Further, then, this universe will end with my end of observation upon my passing.
[aside]
For the younger members here, it is most unfortunate that life is a terminal condition to begin with and given my position on its path your existence may be cut rather short, though I endeavor to delay this ultimate end as long as possible.
[/aside]
The absurdity of this is that we have Linde's recording device where the information of others' observations of the universe's existence prior to my consciousness is preserved (all omphalism aside).
It appears, then, that my personal observation of the universe is not a necessary condition for its existence. By extension, this universe exists independent of my consciousness, or the consciousness of Linde or Wheeler or anyone else.
I submit that there is in fact a "recording device" where the information of the existence of the past universe is stored. It is in the shape, content and state of the present universe, all recorded by the physical laws from its past states. It requires a conscious intelligence to decipher and understand the record but it is there regardless of the existence of any specific, or all, consciousness.
The record exists independent of any intelligence advanced yet enough to decipher its code. The universe exists independent of any consciousness present to observe it.

Re: Philosobabble.
In a lot of ways I think that makes more sense of things considering what relativity tells us about time.
However, if you read the rest of my message, you will see where I conclude that this idea is false.

I guess the point would be that you hear the speech in your head but somebody with a stethoscope up to your head wouldn't hear it. You don't have a speaker somewhere in your head. As he says: where is the playback?
The playback is still in your head.
Your brain does not "hear" the sounds coming into your ears.
The sound enters your ears and vibrates cilia. The cilia are connected to cells that, when sensing the vibration, send an electrical impulse through the auditory nerves to the region of the brain that is wired and chemically composed to interpret those electrical signals. It is this cascade of events the we term as "hearing".
When I was in Grad School I shared an office with another Grad Assistant. His visual systems worked just fine as he could see the colors and shapes. But there was a "cross wiring" in his brain that also sent those visual signals to the auditory portion of his brain. He would "hear" colors and shapes. That was his normal reality.
These types of things neither evidence nor deny the existence of a soul. You need to look elsewhere.
