Electrons and photons: two indivisible elementary sub-atomic particles, two bricks of which Our Virtual Reality consists; that is, light, whose smallest unit is the photon, and electricity, whose smallest unit is the electron.
When we talk about electrons and photons, we talk about both particles and electromagnetic waves.
The theory of photon and electron wave-particle duality served to unify the two schools of thought of the great scientists of the '20s: the school that embraced Einstein's thought, supported with his studies of the nature of the photon and the electron as a particle, which have mass; while the school of De Broglie argued the nature of the photon and of the electron as waves, that is, massless.
These two schools of thought were born of the results of experiments performed on electrons and photons that gave exact results in both cases, reflecting all theoretical expectations. But the working hypotheses of the two schools were based on extremely different concepts: the experiments that assumed that photon/electron had weight (a mass) were proven correct, as were the experiments that assumed no mass.
In the end, both schools embraced the idea of the dual wave-particle nature of the electron and photon, as the only way to set right all of these disagreeing experiments: in some situations, the calculations considered the electron and the photon to have mass were proven correct, while in other situations, the calculations considered them massless were proven correct too, but the absurdity of such a situation is never emphasised.
Great scientists can never be wrong, so wave-particle duality gives reason to both schools of thought.
If one pauses to think for a moment, the logical absurdity is more than obvious; it does not take a genius to see it.
Let's take a similar, trivial example: let's suppose that two groups of researchers are studying an animal that has never been seen before; one group of researchers claims to have evidence that this animal is a mammal, while the other group publishes studies that show that this animal is a reptile. Even if this new animal behaves like a mammal in some cases and a reptile in others, it obviously belongs to another class which is neither reptile nor mammal, and nobody would dare claim that this animal is a dual-mammal-reptile. It's obvious.
But for a hundred years now we have been talking about wave-particle duality, despite the fact that it is a logical absurdity; wave-particle duality has been indoctrinated as truth and anyone who has studied science is ready to defend this concept with drawn sword.
The absurdity of the wave-particle model is also evident in the anomalous manifestations of electrons and photons that are inexplicable with physical-mathematical models proposed thus far.
The theory of wave-particle duality was pulled out in order to avoid admitting the limits of official science on the true physical meaning of the electron and photon.
All the expressions and phenomena of photons and electrons that we notice in Our Virtual Reality are only part of a more complex phenomenon, which includes other dimensions that we cannot fully appreciate with our limitations. If one could consider and evaluate the phenomenon in its entirety, their non-particle and non-wave nature would be clear, and mysterious cases of quantum mechanics would be solved.
