What I referred to is to the best of my knowledge - the standard version of the experiment.

The following is a link to an article to an article on John Wheeler's views.
Does the Universe Exist if We're Not Looking? This quote referes to Andrei Linde's views from this article.
quote: Everybody is entitled to my opinion.

If your answer is "no", the next question is: Did the universe exist before we started looking at it? Does the Universe Exist if We're Not Looking? Our observations suggest that it did. I rode off into the sunset, went all the way around the world and now I\'m back where I started.

Does the Universe Exist if We're Not Looking? Does anyone even care? Anyone so limited that they can only spell a word one way is severely handicapped!

I am not going to pretend that I am qualified to argue this point one way or another. I have read a couple of books on the subject and think they make a good point. I think that Linde among others is at least qualified to comment with some authority on this and to just call it poppycock doesn't do much to refute his point. I don't think that anyone has said that it requires a human observer. I think that my golden retreiver would qualify.

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.

I don't think that anyone has You are correct in saying no one can refute this point. Neither can one confirm it. It is purely philosophical idea and has no emperical evidence supporting it or opposing it. Thus I will qualify my statement by saying scientifically it is poppycock as there is no way to prove or disprove it. Just like you cannot prove that a chine teapot does not orbit the sun halfway between the Earth and Mars. Does that make you happy Edited by DevilsAdvocate, : No reason given.

Science is one thing. Philosophy is another. Whether the universe exists when no one is looking is Philosophy, not science.

quote: I don't agree that Lind has any special authority. Given the fact that there are no experiments that show that consciousness is required at all, it seems that all he offers is philosophical musings without real evidence. What, then, qualifies his opinion as authoritative to any significant degree ?

Linde writes: The moment you say that the universe exists without any observers, I cannot make any sense out of that. I cannot imagine a consistent theory of everything that ignores consciousness. GDR writes: I think that Linde among others is at least qualified to comment with some authority on this and to just call it poppycock doesn't do much to refute his point. Is he qualified to "comment with some authority" by his lack of imagination?

I don't know if it's Linde misunderstanding Schrdinger or Schrdinger misunderstanding CSI but the fact is that we can determine an approximate time of death from present-day observations. I'll just repeat what Linde said in the quote I used above.
quote: It's one thing to say that an observer effects the observation - e.g. inserting a thermometer changes the temperature of both the thermometer and the sample. It's another thing entirely to say that the quantities don't exist until measured. I rode off into the sunset, went all the way around the world and now I\'m back where I started.

It's one thing to say that an observer effects the observation - e.g. inserting a thermometer changes the temperature of both the thermometer and the sample. It's another thing entirely to say that the quantities don't exist until measured. Well, this is the heart of understanding quantum mechanics. Position and momentum as such don't exist until measured - they simply aren't "things" that "exist" - they are answers to questions that are asked. This is the basics. Extrapolating that to life and death is another thing, I agree... possibly. Oh, and great to see you back Edited by cavediver, : No reason given.
