The usual quantum nonsense from physicists pretending that light, when sent through a double slit, is sometimes observed to be a photon and other times as a wave. Fact is; Light isn’t ever actually observed to be a photon. That is a false assumption. Seeing as no one can actually see an imaginary photon as it hits the photodetector plane. All we see is a readout on a pc screen of wave light incident on the photodetector. And as a classical wave only model correctly models, that incident wave radiation is quantised into pulses by the detector atoms and delivered, as an the ‘electron cascade’, to the circuit. To be then sent to the computer screen as dots. Dots that theorists incorrectly assume to be imaginary photons. Any interference pattern created by these dots is simply a readout of the intensity of wave only incident radiation on the detector screen and at that corresponding point on the pc screen. Where there is more light due to an interference pattern at the detector plane, there will be a greater intensity of incident wave radiation at that point. And more of these quantised dots will  appear at that corresponding point in the interference pattern on the computer screen. 

And where there is less incident wave only radiation at other points in the interference pattern there will be fewer quantised pulses from the photodetector and thus at that same corresponding point on the pc screen, fewer dots will be observed. 

No quantum wave particle duality is needed to explain both the dots and any of those dots creating the interference pattern. 

That is unless one is a QT theorist who, when looking at these dots on his pc screen pretended they were photons hitting the detector plane. And then erroneously assumed this collection of these imaginary photons arranged themselves magically into a wave like interference pattern when the source atoms were constrained into a coherent lattice. In fact, all they actually saw was an amplified second generation image of wave only light being quantised at and by the photodetector atoms. Then amplified electronically and delivered via software to the pc screen as an interference pattern.

But to deal specifically with this papers claims of quantum photon/wave duality magic is the following scientific classical wave only theoretical explanation:

What is creating the coherent light in the experiment described in above cited paper? 

If the array of atoms is held in a lattice and reflecting/re-emitting the incident laser light then the atom lattice is essentially a collection of coherent light sources. As we know only coherent light when split into two or more same coherent sources at a “slit” can create interference patterns when incident on any detector plane. First described in Thomas Youngs famous slit screen experiment.

And further to this, what is creating the incoherent light in the experiment when no interference patterns from the source atoms are observed? 

If the atoms are not in a lattice and moving randomly, and reflecting or re-emitting this incoherent light onto the detector screen, then at this point we know that no interference patterns can be created or observed from two or more incoherent sources. This is indeed observed in the above cited paper.

Because, as any one with a basic grasp of physics knows, two or more incoherent light sources cannot produce an interference pattern. And thus in the experiment only the atoms held together in a lattice and reflecting or re-emitting the light are considered multiple coherent light sources. And as mentioned above, two or more coherent sources can create interference patterns at any detector screen. As is observed and confirmed in the paper.

In their attempts to pretend they have supplied further proof of the quantum nature of light, the authors of the paper have forgotten basic physics. In that a classical model can fully explain their experimental results. In that in a wave only classical model of light, any incoherent classical wave light sources will not produce any interference at a detector plane. And will only do so only if the multi atom incoherent light source is artificially constrained into a lattice of multiple coherent light sources that can then produce interference. As is observed in the paper.

Quantum Magic: How Scientists Are Untangling the Universe’s Weirdest Mystery. Carl Kocher

I’m glad Carl admits QT is just magic. As he explains further at the end of his article with the following question, quoted below:

“Take another look at predictions #1 and #3 above. If we draw on our experience of life in a non-quantum world, we may notice something very strange when the polarizers are “crossed” at 90 degrees. If each photon has a 50% chance of transmission through its polarizer, why don’t we get coincidences 25% of the time? Instead, we observe none at all. At first consideration, this does seem to qualify as a paradox. One possible explanation could involve a missing component of quantum theory – perhaps a causal mechanism that could allow one photon, or one measurement, to communicate with the other. However, despite extensive research, no evidence has been found for such a mechanism.” Carl Kocher

https://scitechdaily.com/quantum-magic-how-scientists-are-untangling-the-universes-weirdest-mystery/

It may be a magical mystery for Carl Kocher. But the reason behind Carl’s mystery is that he believes in Einsteins fantasy photons and QT’s magical mystery tour. Because a traditional Young Huygens wave only classical model of light and an understanding of polarisation can fully explain the ‘no coincidences’ recorded when the polarisers at the two detectors are crossed in Carl’s experiment. Without having to resort to magic or mystery.

First of all one must understand how the source light is polarised. Carl confirms that the source beams of 551 and 423 nm from the excited calcium source are unpolarised. However he also admits that both beam paths will always have the same polarisation state when they arrive at the detectors at any one point in time. As long as both path lengths are equal. (“More generally, if one of the photons passes through a linear polarizer at any orientation, the remaining photon will then be in the same polarization state, pending future measurements.” Kocher)

And so when the two beams (423 &551nm) arrive at the two detectors, both detectors will receive light at any one point in time that will always be in the same polarised state. As long as both path lengths are identical. (This incidentally is the purpose of the coincidence counter. It records all counts over the time span of the experiment, but collates counts from both detectors to match them both to the same time of emission to check for coincidences. Which is also defined as the same path length)

And therefore, as Carl says in his article, if he crosses the polarising filters by placing a horizontally polarised filter in front of detector A, and a vertically polarised filter in front of detector B then only one of the two detectors can detect any incident wave light that left the source at same time. Unfortunately for Carl, real physics doesn’t use QT magic. And light is wave only. So instead of 2 imaginary magically entangled photons arriving at the detectors, it is just 2 same polarised points in the wave-only light beams (423 &551nm). With the proviso, as Kocher admits above, that both these beams when emitted will always be emitted with the same state of polarisation. And therefore they both arrive at the detectors with the same polarised state. Provided the two path lengths are identical.

For example if both detectors are receiving the same vertically polarised part of the lightbeams simultaneously, but only one detector can receive vertically polarised light due to the crossed filters, then obviously only one detector will detect any light at any one time.

Hence no coincidences will or can be recorded. Exactly as observed. 

Not only is this a physical mechanism that can explain the experimental results, no QT magic is needed either. Just a plain old classical theory of wave only light as described by Young and Huygens

Physicists measured Earth’s rotation using quantum entanglement

Physicists measured Earth’s rotation using quantum entanglement! Since when has classical wave interference become “Quantum interference”?

https://www.sciencenews.org/article/earth-rotation-quantum-entanglement

The experimental setup as described in the original Silverstein et al 2024 experiment is fairly complex compared to the original Sagnac version. However complexity here does not mean it is no longer a basic time of flight Sagnac interferometer with observations consistent with a classical wave only model of light.

I’ve seen similar flights of fantasies of supposed ‘proof of QT’ from other very well known “Quantum” experiments. For instance the Kim et al 1999 Delayed Choice quantum eraser experiment. Where on analysis they had only confirmed the classical model of light. Where light is a wave only and not a photon. 

The technique is also used here. QT ‘researchers’ also have made the experiment as complex as possible so as to disguise the fact that the experiment can still be explained classically without referring to relativity or QT. I have comprehensively dissected Kim et al’s Delayed choice experiment setup and shown how adding complexity is also used to prove Quantum fantasies, at this following link http://physicsexplained.blogspot.com/2015/11/the-main-illustrationbelow-is-schematic.html

The same applies to this current 2024 experiment. They manage to pull off this Quantum trick by pretending that somehow ...classical polarised states of wave only light and wave interference are signs of the light being a particle and subject to quantum nuttiness!! 

The fact is that in this experiment there is still only just a path difference detected. And it is detected, as usual for any Sagnac interferometer, via interference patterns. Nothing more. They even admit this is all thats observed. The sleight of hand here is QT dogma at its greatest. They pretended that classical wave interference, observed and documented for centuries by Young and others... is somehow now called “Quantum Interference”

Laughable nonsense as usual from establishment physicists.

Quantum interference in atom-exchange reactions

As usual the quantum theorists just can’t bring themselves to admit QT is nonsense. The Bohr model was a failure and QT should never have been let loose in theoretical physics. All atoms and EMR are wave only. They are not made of particles like photons, electrons neutrons etc. Essentially the atom is a wave only superposition of EMR interfering at a single central nodal point. As the wave only classical theoretical model at these links explain:

Hydrogen Spectral Series as Harmonic Overtones of a Single Fundamental Wavelength

Photoelectric effect described by a classical model

Wave only atom

CERN ‘particle paths’ modelled as overlapping waves

This wave only atom model, by virtue of the atom being a nodal point in space and made up only of standing waves of EMR, will have a dipole N-S magnetic field associated with this nodal point. As described in the above link ‘Wave only atom’. And when this wave only atom moves relative to any other reference frame it will itself also produce wave only magnetic radiation. A circular model described in the above link ‘CERN Particle paths modelled as overlapping waves’.

In a wave only classical model, oscillating magnetic fields of EMR will interfere with each other to create the atom as a nodal point with an associated dipole magnetic field. Which then itself generates new EMR when it moves relative to any other atom in any other reference frame.

This classical model is continually confirmed by so called Quantum “research” . It seems that every time QT theorists look ever closer at the atomic scale with ever more sophisticated technology ...they always find that the atom ( and EMR) has only wave like properties. With those  properties well described by a wave only classical atomic model. As my quote below from an article on the latest Quantum research shows :

(Notice in the article on the paper, quote cited below, that the quantum researchers were surprised to find the atoms in their experiment were acting classically. As if the atoms resonant frequencies were being synchronised. They just ‘discovered’ a well documented classical effect which has been known for centuries. And called it a quantum effect!!)

 “If you zoom in on a chemical reaction to the quantum level, you'll notice that particles behave like waves that can ripple and collide. Scientists have long sought to understand quantum coherence, the ability of particles to maintain phase relationships and exist in multiple states simultaneously; this is akin to all parts of a wave being synchronized”

https://phys.org/news/2024-05-scientists-survival-quantum-coherence-chemical.html

This synchronisation phenomena does not need to resort to a quantum magic explanation. A simple wave only classical model using sympathetic resonance between two wave only resonant systems will suffice.

When will these QT theorists admit that the standard model and Quantum physics should be scrapped? And replaced with a wave only model of the universe where there is no Big Bang. No QT. No Relativity. And No standard model Particles.

When? Who knows. It’s amazing they haven’t realised this yet. It must because they studied too much maths. And not enough classical physics.

Quantum ultra cold atomic magnetic spins refute Bohr model

 It’s amazing how the Bohr model continues to fail to model what actually happens at the atomic level of atoms their spectral lines and their associated magnetic fields. This paper in particular  explains the failings of the Bohr model with respect to spectral lines: 

https://vixra.org/pdf/2302.0102v1.pdf

However, as technology advances this also allows us to look closer at how the atoms magnetic field itself behaves. And as we look closer we find out that atoms magnetic fields , incorrectly assumed to be “spinning” electrons, are actually just small magnets interacting with each other. Confirming the theoretical modelling outlined in my article and video on how atoms, their magnetic fields and flow of electricity actually are modelled mechanically.

It’s surprising how close the illustration of what is happening to atomic magnetic fields in this paper 

https://news.mit.edu/2020/ultracold-quantum-magnetic-atom-spins-1216

reproduces earlier theoretical modelling of mine made in this video linked below. When will quantum theorists admit their electron spin model is outdated and needs to be replaced with a much simpler model as outlined in my research linked below.
