The way it !SHOULD! work 'classically' is electrons and positrons, the only true fundamental particles are an in-out vibrating globular field warp in the subspace field of close-packed +ve balls bound by -ve gas. The electron has 1 quantum (1 cell's worth) of extra -ve charge left over from a cell being kicked free (that became a positron).. The -ve gas flows from the centre to the outer edge and back as a wave, with cells being pulled in and out at C.. -- There are 6 (or more?) DC Mass Spin Loops of -ve gas and cells in a torus too.. A magnetic field is the same but with cells as vibrating AC cell blips in the direction of -ve gas flow... When a particle accelerated hard its energy field can momentarily massively weakens, and the 1 quantum of extra -ve gas at the electron core travels as a tiny ball of extra -ve gas. It's field reforms at C but the electron is going so fast it doesn't have time to establish a large coherent field until it leaves the field of the barrier electron.

@ParthGChannel4 жыл бұрын
Yeah the way I think about it is that humans invented the concept of "waves" and "particles" based on what we could observe in experiments. We saw that electrons behaved like particles and light behaved like a wave, just purely coincidentally based on experiments we did in the past. However we later discovered that electrons can also behave like waves and light like a particle. So we need to come up with a new model that describes the true behaviour of all of these bits of the universe, that incorporates both wave-like properties and particle-like properties. :)

My theory is that a particle, under certain conditions, can transfer its charge to its momentum, causing it to collapse the wave function temporarily, and therefore eliminating the barrier. Because the particle expended energy in this way, it now exists in the lower energy state. Its charge is depleted. This is because the electron is made of even smaller particles that are truly fundamental and are responsible for mass, charge and spin. When they align in a specific way, some are discharged from the electron's shell, generating momentum. The electron then redistributes its remaining particles to return to equilibrium. We do not register those smaller particles because when they fly away in a straight line, they are superluminal. It is only when their path curves, generating curved spacetime, they slow to 1/5th and give their energy to momentum by the flywheel effect which in turn lightens the mass. The mass energy is the number of particles inside. The charge is the potential for that energy to be released. The spin is based on the grouping of particles into two (spin 1 in bosons) or three (spin 1/2 in fermions) groups in orbit around each other. For those not in the know, that's primarily classical, not quantum mechanics, because classical looks for causes in physical bodies, not fuzzy collections of wave functions. What proves particles real is that they are subject to the wave function only as long as the wave function is active. It is only active as long as the particle remains subject to the cosmological constant. (Which is a whole other subject in itself.)

That's how the sun is emitting light, as far as I have been taught: pressure, temperature, energy are not enough alone to cause fusion, which implies 2 things : - that's why thankfully fusion inside the sun is very ineffective, thus giving it billions of years life - wave function is not only a mathematical representation, but somehow a real matter thing. Well can we still call it matter at this stage ? That leads my mind to QFT. Am I the only one who came to this thought ? Anyone feel free to correct my reasoning and line of thoughts, I am no physicist, just passionately curious about a world richer than what it looks like.

Thank you for your great explanation. In the Schrodinger equation, is V the potential energy of the region around the electron or is it the potential energy of the electron itself? My textbook, in my understanding, says V is the potential of the electron, whereas E is its total energy (sum of potential and kinetic energies). If this is the case, how can potential energy be greater than total energy?
@schmetterling44772 ай бұрын
V is the potential of a field. That field is a classical approximation that does, in reality, not exist. If you wanted to understand the microscopic mechanism for tunneling, then you would have to quantize the field as well and then you could treat this scattering problem with perturbation theory and you would see that "the particle" does not move in a potential but it scatters in a sea of other particles. It would still be the wrong explanation, but at least you would think that you understood what is going on.

Electrons are coiled Aether fields, not particles. A straight wire, into a coiled wire. Parallel magnetic fields, into Unparallel magnetic fields. Compressing into each other, charge. J.J. Thompson, the discoverer of the Electron, said the electron wasn't a particle. Until he was offered a Nobel Prize. Tunneling dropping its magnetic transverse wave, leaving only its Dielectric energy. That doesn't create Tesla nodes, as transverse waves, no EM waves perturbations. Dielectric energy is longitudinal perturbations along the Inertial plane/Counterspace.
