| Or si, à l’échelle de la vie quotidienne, nous pouvons approximativement considérer le monde comme s’il existait une séparation entre observateur et objet, nous savons que tel n’est pas le cas au niveau atomique et subatomique. À ce niveau, la mécanique quantique nous apprend que cette division est factice : l’observateur participe de la réalité observée, l’influence et est interdépendant avec elle. Ainsi, une particule élémentaire revêt son habit d’onde et peut être partout à la fois dans l’espace quand on ne l’observe pas, mais redevient une particule sitôt qu’on l’observe. Le fait même d’observer modifie la réalité extérieure. |

| John Wheeler is impressed by the fact that according to the standard Copenhagen interpretation of quantum mechanics, a physical system cannot be said to have any definite values for quantities like position or energy or momentum until these quantities are measured by some observer’s apparatus. For Wheeler, some sort of intelligent life is required in order to give meaning to quantum mechanics, Recently Wheeler has gone further and proposed that intelligent life not only must appear but must go on to pervade every part of the universe in order that every bit of information about the physical state of the universe should eventually be observed. Wheeler’s conclusions seem to me to provide a good example of the dangers of taking too seriously the doctrine of positivism, that science should concern itself only with things that can be observed. Other physicists including myself prefer another, realist, way of looking at quantum mechanics, in terms of a wave function that can describe laboratories and observers as well as atoms and molecules, governed by laws that do not materially depend on whether there are any observers or not. |
