I don't really know what your saying. When Quantum field theory says that an electron is a excitation in the electron field, what does that mean? Does that mean that it is a quanta of the field or a particle of the field... what does excitation of the field mean?
In string theory/M theory, there are two types of strings, open and closed strings. What kind of strings are fermions(electrons, quarks) made out of? Closed or open strings?
In QFM, what does it mean to say that an electron is just an excitation of the electron field? Does this apply to all particles? Does it mean to say that an electron is the quanta of the electron field?
Ok, but does the delay choice experiment play any part against the belief that the wave like nature of the electron in double slit collapses do to the instrument physically interacting with the electron, and that it is really just the act of observing that causes the wave like behavior to...
I think my question before is a little unclear but let me edit it...
When the electrons go through the double slit they create a wave like pattern. However, when there is a tracker to measure the electrons, they create a double band particle pattern. Could it be that the instrument used to...
Is the collapse of the wave function of the electron in the double slit experiment based purely on the act of observation? Or could it be that the way the instrument used to measure the electron caused it to collapse by how it physically interacted with the electron? Keep in mind the delayed...
Ok,what I mean is, in realist interpretations of QM, does an electron have a location before it is measured? In copenhagen interpretation (anti realist) it doesn't have location until it is measured. But what about realist interpretations?
Sorry if I might be asking repetitive questions. But in all Ψ ontic interpretations of qm where the wave function is real( MWI, de brig lie, penrose, etc), they physically do not extend to infinity?
