In the beginning there were only probabilities. The universe could only come into existence if someone observed it. It does not matter that the observers turned up several billion years later. The universe exists because we are aware of it. — Martin Rees Professor of Cosmology and Astrophysics and Master of Trinity College at the University of Cambridge. As far as I understand, In Schrödiger's cat experiment, The Copenhagen Interpretation claims that at the moment that you open the box after one hour, it is in that moment that the past of the cat (either whether it is death or alive) is decided. basically as I understand it the past is being created in the act of opening the box by a conscious observer. If this is true what are the implications for macroscopic objects? For instance if im with a geiger counter and if a particle decays, is it the fact of me watching and being aware that a particle decayed what makes it come into existens? If this is true , what would happen if my geiger counter registers a particle decaying and keep the record of it but I don check the geiger counter until one year later? would I be making that particle to come into existens one year after the geiger counter detected it? Extending this to the early universe, and to the remanecesce of particles in the early unvierse perhaps from the Cosmic microwave background radiation or some other remanecesce of particles in the early universe, could they have been created in some way by the fact that conscious observers exists in the universe. Finally could the big bang have been created because of consciouss observers inhabiting the universe? is this the logic the one that Martin Rees used when he said the above mentioned quote?
