User:Authorfieldsofcolor/sandbox/insertion to "Measurement problem"

The following (slightly modified) was inserted in 'Measurement Problem" article at the end of the "Interpretations" section. I would like to know why it was deleted.

Besides the above solutions based on Quantum Mechanics, there is a different solution offered by Quantum Field Theory in its “fields only” sense as formulated by Julian Schwinger . (It should be noted that this is not the usual interpretation of QFT.) The QFT solution is in accord with our intuitive beliefs. In fact, for those who believe that the world is made of quantized fields, this is the only possible solution to the measurement problem. The problem was created because Quantum Mechanics does not provide a consistent picture of reality. It deals with superpositions of states with various probabilities that collapse when someone looks, but it doesn’t describe what happens until then. Quantum Field Theory, on the other hand, offers a picture of reality at every moment of time, even when no one is looking. This picture consists of fields (properties of space) that are present at every point, but with field intensities that are specified by vectors in an abstract Hilbert space, not by simple numbers. These fields evolve deterministically according to the equations of QFT. However the field equations do not tell the whole story; they do not describe how energy is transferred from one quantum to another. So in addition to the evolution governed by the equations, there is another process in which a field quantum deposits its energy (or part of its energy) into another quantum and disappears from all other points in space. While this collapse is not described by the equations of QFT, it is necessary if quanta are to be indivisible units. Thus the QFT picture of a measurement consists of two phases. In the first phase an incident quantum, say a radiated photon, interacts with all quanta that it encounters, as per the field equations. This interaction is reversible and may be called the “entanglement” phase (although that word is sometimes used in other senses). Then, at some point that cannot be determined by the theory, the incident quantum collapses into another object, say an atom in a Geiger counter, and transfers its energy to it. This process is irreversible and initiates a chain of events that may lead to a macroscopic change. For example, in Schrödinger’s cat experiment, when the radiated quantum collapses into the Geiger counter, an electric current is created that trips a relay that releases the poison gas that kills the cat.
