Quantum Confusion -- "Does not exist until it's observed" and age of universe Hi. I ran across this: http://physics.jamesbaugh.com/quanta.html [Broken] QUOTE: "It is a problem of assuming values of properties are "out there" independently of the acts by which the values are determined. The whole meaning of the value of a property is the value obtained by a physical, dynamic act of measurement. To say what the position of an electron is "between position measurements" is as nonsensical as to say the electron is a "Republican" or "prefers orange to peach jelly for breakfast". Science and especially physics is about what we know as that is defined by empirical actual experiments." So then I suppose, by the above, to talk about the position "in the vast ocean of time before measuring devices and humans existed" is "nonsense". But that itself doesn't, erm, make sense. It would mean that entire, vast fields of science -- cosmology, archaeology, palaeontology, geology, etc. would all be utterly meaningless since they'd be talking about conditions and things in a time when no "measuring devices" existed to make physical properties of "stuff" meaningful. If anything, it'd seem to lead us to take seriously the notion of this: http://en.wikipedia.org/wiki/Omphalos_hypothesis -- the universe's true age is limited by the time us and our measuring devices have existed for, which means the "13.7 billion years" often cited would actually be a meaningless figure, since it makes no sense to talk about a "universe" without observers in it to make things concrete. It would indicate that the universe appeared, in essentially its full form and only _seeming_ to be old, a few decades(!) or at most a few tens of thousands of years ago, when humans (for "observers") first appeared. (I suppose we could be generous, and try pushing it back a few hundred million years even, to the point of appearance of organisms with brains and what not. But billions of years? Forget it!) But that just don't seem right! What gives? What is the meaning of "the pre-human or pre-life universe" from a quantum point of view?
