The discovery of quantum phenomena has given rise to an enormous number of interpretational difficulties. This assumption at least has the advantage of not being anthropocentric with respect to the scientist. Wigner resolves this difficulty by postulating that it is not merely the observing scientist which is responsible for the reduction of the wave packet, but any perceiving consciousness. Entities such as events, particles or waves are postulated to exist, and to have properties which are compatible with the existing rules of quantum mechanics. In the face of the above (seemingly astonishing) proposals for the reduction of the wave packet, there have been proposals, Online Casinos for USA Players - No Deposit Bonus The Worlds Heisenberg on, that the reduction occurs as a natural physical process, and is not dependent on the attention of any observing scientist. Thus the reduction of the wave Online Casinos for USA Players - No Deposit Bonus Casino Mac could occur in part of the observing apparatus, and need not have anything to do with observers and/or their consciousness. An alternative approach starts not from existing physical theories, but from some general considerations about what could possibly exist. A corresponding range of rather slide proposals for quantum ontologies have been proposed, in the attempt to try to understand quantum mechanics realistically. That intepretation becomes much less clear as a quantum ontology. Any observers (whether conscious, living or computer-based) will be automatically replicated into slide several branches, and in each branch will record the appropriate observations for that branch! Again, this theory never allows a splitting between the alternatives in the wave function to become apparent to any observer, because the very act of any observer looking is responsible for the splitting of the wave function among the various alternatives. This means that in the many-worlds interpretation, we never really have many worlds, but really one world set which contains all the different slide worlds. We find this even more difficult to believe.
