hi guys, i just have a quick question concerning the Copenhagen interpretation of things. say there is a star, very far away (perhaps 1 billion light-years from Earth) that for the sake of this idea, has never been observed, by any intelligent being, anywhere. we happen to turn our telescope or observational instrument in the direction of this star and observe it for the very first time. The light that we are observing took one billion years to travel to us from the star and the act of observing this star collapses its wave function into one reality (the reality that the star exists, at this location, at this time 1 billion years before observing it). Now because this light is essentially 1 billion years old, and by observing it, we collapsed its wave function and 'crystallized' its place in reality, are we changing the past of the star itself? (since the star is 1 billion years ahead of time of when we observed it) i don't think that came out as coherent as i would have wished but if you need me to explain more please ask. thanks in advance, Michael.
