The Pauli Exclusion Principle originates from the inability of two electrons to occupy the same quantum state.
The Pauli Exclusion Principle practically makes the world “solid” by restricting atoms from occupying the same space, introducing tangibility in the universe.
The electromagnetic manifestations of the entities photon and neutrino themselves are not tangible. However, once the atom is built and the electron shells are formed and filled, the phenomenon of tangibility comes into play when atoms collide. This is the fundamental concept referred to in the Pauli Exclusion Principle.
The definition of the Pauli Exclusion Principle is with quantum numbers.

The Pauli exclusion principle is the quantum mechanical principle which states that two or more identical fermions (particles with half-integer spin) cannot occupy the same quantum state within a quantum system simultaneously. In the case of electrons in atoms, it can be stated as follows: it is impossible for two electrons of a poly-electron atom to have the same values of the four quantum numbers: n, the principal quantum number, ℓ, the angular momentum quantum number, mℓ, the magnetic quantum number, and ms, the spin quantum number. For example, if two electrons reside in the same orbital, and if their n, ℓ, and mℓ values are the same, then their ms must be different, and thus the electrons must have opposite half-integer spin projections of 1/2 and −1/2. This principle was formulated by Austrian physicist Wolfgang Pauli in 1925 for electrons, and later extended to all fermions with his spin–statistics theorem of 1940.
The key point is that two electrons in the same state of oscillation cannot interfere with each other. Based on current understanding, this means that two electrons cannot interfere, but an electron and a positron can exhibit an annihilation pattern.
In the Large Electron-Positron (LEP) machine, such collisions produced the following result:
The Dutch Paradigm clarifies that a positron is not the anti-particle of the electron but the same type of electron, but in opposite oscillation.
The Pauli Exclusion Principle implies that electron-electron interference is not possible. According to the postulates of the Dutch Paradigm, this makes sense. Such interference would breach the speed of light limit.
In the discussion of the forming of the neutron bond, it was explained that only by exerting strong forces will one of the two colliding electrons break and eject a neutrino.
