    It all collapses to: 1) What do you define the meaning of "electron size"? 2) What actually is an electron? 3) Electrons are NOT Newtonian objects, but we are asking a Newtonian question about size?

    No one mentions that in classical terms the radius of the electron reduces as its speed and relativistic mass increase. The effective wavelength (a classical indicator of size) also reduces with relativistic velocity.
    Also classically other models other than a simple sphere were considered for the shape of an electron.

    Based upon the experimental results, it appears that an appropriate answer might be, as small as you want to make it, which I find a bit strange. For example, what if we localized an electron to a region smaller than its Schwarzschild radius? Of course, I have no idea how one might accomplish that. Exercise for the reader: calculate the energy required by a photon to localize an electron to within its Schwarzschild radius by Compton scattering. Still, it does present a theoretical conundrum.

    本篇的討論只在於原子中的電子現象,而不從原子的生成邏輯來討論,這就像研究樹木只看地表上的枝幹卻不看吸收養分的根一樣,永遠在虛空幻想。
    原子是中心為質子,而繞質子運行的是眾多不同能階的基本粒子,這些基本粒子的總能量稱之為電子,而這些基本粒子的能階與光粒子接近,所以只要你加能量就會將其激發出光波離開表面,等這能階被激發完,就無光釋出,但只要加高能量就會有另一能階的基本粒子接續發光,由這個觀點往前推展就是質子與中子的形成也必需符合相關的演化邏輯。
    大霹靂是使本宇宙有能量,這是確定了的事實,但是是從奇點看啓,這是我無法認同的,也就是說大霹靂前的天體必然要有一個生成的空間,而這空間的能量是遠小於本宇宙的,這個宇宙零度(地球溫度下10^22°C)的母宇宙是讓10^-27焦耳的能量凝結成一顆光粒子質量的能質粒子(無中生有),能質粒子間以能階差結合成無動能、無距離與密度無限大的粒子個體,這就是黑洞最小單位,而這粒子個體間以能階差形成了相對運動,這就是引力的起源。
    粒子個體間的相對運動最終以踫撞融合長大結束,在融合時動能轉化為熱能提升合體後的能階,所以黑洞越大其體內的能階越高,當黑洞體內的能階高過內聚力就會自爆,所以黑洞的體積是有極限的(估計有銀河系的大小,引力達50億光年)。
    大霹靂發生前宇宙最大黑洞其周圍有最密集的黑洞系統,當黑洞自爆時失去了引力源的黑洞系統就會以切線方向離心速度飛離中心點,此時大質量黑洞就率其可影響的黑洞系統以同一個方向飛行,從側面看就是扁平狀運行的天體,這就是星系團的雛型。
    大霹靂的高溫與能質粒子以質能轉換產生了電磁輻射(宇宙背景輻射)、光粒子、原始粒子(基本粒子與量子)與暗物質(能質粒子提升能階而得,所以佔總質量90%是合理的)。
    赤熱的原始粒子以球狀向外擴張,最外圍的原始粒子與能質粒子接觸動能急劇下降,使粒子間的能階差發生了效應結合成粒子個體,這就是夸克誕生機制。外圍的原始粒子速度減慢與夸克的生成使後方高能量與高速度的原始粒子超過,於是宇宙最大的壓力鍋就誕生了,夸克在壓力鍋內的數量持續增加,在高溫、高壓與高密度的綜合作用下,夸克間也以能階差結合成夸克個體,於是質子與中子就誕生了,這個由原始粒子、夸克、質子與中子組成的綜合體我稱之為原始粒子濃湯。
    原始粒子濃湯的擴張速度遠大於黑洞系統的離心速度,在被追過時黑洞系統成員也都以能階差截取適量的原始粒子濃湯在身上。此時裹著原始粒子濃湯的黑洞系統就已轉成星雲體,而星雲體的飛行軌跡就是紅移現象,所以宇宙擴張是離心力造成的,無需加入暗能量項次。
    星系團是裹著原始粒子濃湯的黑洞系統,所以作為子系統的恒星系統也是同樣架構,以太陽系為例,太陽中心是黑洞,其周圍是高溫、高壓與高密度由夸克、質子與中子構成的硬殼,因需向中心輸送能量,所以硬殼不斷重組與擠壓,使外殼個體脫離噴出,隨離中心程度溫度與壓力也同時下降,而體積也跟著膨漲而夸克的密度也減小了,在溫度、壓力與密度綜合變動下,夸克就裂解釋放出能量與原始粒子,到表面就爆炸形成了日冕。
    恒星的能量來源是夸克的逐層裂解,到恒星末期因外在壓力的卸除,硬殼內高密度的夸克間在短期內連鎖裂解釋放出巨大的能量,形成了紅巨星與超新星,而質子與中子因質量大被黑洞所拘束,只能在表面形成了硬殼,於是磁星與中子星就誕生了,當能量被吸噬殆盡就回歸黑洞原貌。
    行星的質量小散熱快,當表面溫度降到600°C時,上空數百公里處的溫度近絕對零度,此處的原始粒子的動能趨近於零,當表面下的重組擠壓使高能量的質子被噴到數百公里處,因能階差很大使原始粒子主動向質子靠近,進而繞質子運轉,於是原子就生成了,而繞質子運行的眾多不同能階的原始粒子的能量總和就是電子,所以電子沒有固定形狀。

    Electron is as the photon - a wave. As such, waves are intrinsically spread-out. Their energy, charge and mass are a wave and therefore their position is spread-out as a wave. Where is the wake of a boat? One can point to the wake of a boat, but upon closer inspection it becomes clear the wake is spread over several cycles. Same with an electronic wave in a circuit, say the square-waves in a digital computer. Look more closely at the rising or falling edge and one sees a tiny ringing of a wave. Like the wake, from a distance the edge's position appears sharp and easily identifiable, but upon closer inspection, the signal is a wave and the wave cannot be precisely located to a single time/position. (more...)
    When one measures waves, their position is defined by a 'wavelength,' not a point. And when one wants to describe a wave's approximate position at a single point in time, one describes its "Full Width Half-Max" (FWHM). FWHM is generally accepted as the wave's "position." But if one were to attempt to capture say, a single-photon of that wavy-signal, they would find that any detector located at a single position in space, would have only a probability of detecting the wave.
    Take for example a single photon of 10cm-wavelength microwave energy impinging a metal surface with probes every 1cm. As the wave hits the surface, only one of those detector-probes will collect the energy of the photon. Which detector is a probability of chance (not a 'quantum' probability). The photon is not a probability-wave and that probability-wave in no way "collapses," (although the single-photon wave would most definitely go down one of those ten detector-holes if it didn't reflect). The photon is comprised of E&H-fields. The same E&H fields one can measure all the way down to DC with a voltmeter. The same fields that exist between the terminals of a 9V-battery and that can be 'tasted' by licking the 9V battery's terminals. Photon is a real object, not a 'probability-wave.' Likewise the electron.
    The electron is also a wave. A matter wave. Electron has a charge, and therefore E&H-fields, BUT it also has a matter-wave component. And just as the photon's E&H fields are out-of-phase (90° out-of-phase in free-space), so too the electron's electromagnetic-charge-"wave" is out-of-phase (by 2) with its matter-wave (which is evidenced as "Spinors"). The electron is therefore not a probability-wave as you, dear reader, have been taught. The electron (proton, neutron, muon, etc) are real waves, with real physical measurables and real physical measurable solution to Schrödinger's wave equation.
    Proof? Take ψ, a probability wave virtually identical to QM's Ψ and plug-it into Maxwell's wave-equation. Guess what? ψ is a valid solution to Maxwell's wave-equation. How can that be, you say? Two valid solutions to the same Maxwell wave equation? Yes, my friends. A little remembered fact about differential equations is that they may have many solutions. Just because you found one, doesn't mean there aren't others. In fact, a probabilistic solution is merely a dumbed-down version of the E&H wave-equation solution. And if one were to work-through all the maths, they will find our new Maxwell's little-ψ exhibits all the same "strangeness" as big-Ψ does in QM. "Unknowability" suddenly appears. as do "collapsing wave-functions" and all the other nonsense that's been taught for a hundred-years.
    Matter-waves also exhibit "exclusion" (two matter-waves can't be in the same place at the same time), and not the superposition of Maxwell-waves. This vid says two electron's can occupy the same "state," which is true, but they also can't occupy the same place/position, thus they 'bounce' off each other.
    deBroglie was a grad-student on the verge of expulsion when he proposed matter was a wave, so he equivocated. He allowed that matter was also a solid-point (which was incorrect). It made his advisors happy and saved his career to equivocate. Unfortunate, since deBroglie was correct that matter is a wave and his advisors (who informally included Einstein) were incorrect.

    Dr. Roger Penrose has suggested instead of trying to create a particle called the "graviton" to explain gravity, why not try to describe subatomic particles in terms of spatial curvature, as in the twist in a piece of real thread.
    What if we add one extra spatial dimension to the "Twistor Theory" of Dr. Roger Penrose? It can be "chiral" by having either Right-hand or Left-hand twist. It can be "Quantized", based on the number of twist cycles.
    If Physicists describe electrons as point particles with no volume, where is the mass of the particle?
    Can one extra spatial dimension produce a geometric explanation of the 1/2 spin of electrons? The following is an extension of the old Kaluza-Klein theory. Can a twisted 3D 4D soliton containing one extra spatial dimension help solve some of the current problems in Particle Physics?
    What do the Twistors of Roger Penrose and the Geometric Unity of Eric Weinstein and the exploration of one extra spatial dimension by Lisa Randall and the "Belt Trick" of Paul Dirac have in common? Is the following idea a “Quantized” model related to the “Vortex Theory” proposed by Maxwell and others during the 19th century? Is the best explanation of the current data a form of “Twistor Theory” first proposed by Dr. Roger Penrose during 1967? During recent years Dr. Peter Woit has explored Twistor Theory as a possible solution to help explain the current Standard Model.
    Has the concept of the “Aether” been resurrected from the dead and relabeled as the “Higgs Field”?
    In Spinors it takes two complete turns to get down the "rabbit hole" (Alpha Funnel 3D--->4D) to produce one twist cycle (1 Quantum unit).
    Can both Matter and Energy be described as "Quanta" of Spatial Curvature? (A string is revealed to be a twisted cord when viewed up close.) Mass= 1/Length, with each twist cycle of the 4D Hypertube proportional to Planck’s Constant.
    In this model Alpha equals the compactification ratio within the twistor cone, which is approximately 1/137.
    1= Hypertubule diameter at 4D interface
    137= Cone’s larger end diameter at 3D interface where the photons are absorbed or emitted.
    The 4D twisted Hypertubule gets longer or shorter as twisting or untwisting occurs. (720 degrees per twist cycle.)
    If quarks have not been isolated and gluons have not been isolated, how do we know they are not parts of the same thing? The tentacles of an octopus and the body of an octopus are parts of the same creature.
    Is there an alternative interpretation of "Asymptotic Freedom"? What if Quarks are actually made up of twisted tubes which become physically entangled with two other twisted tubes to produce a proton? Instead of the Strong Force being mediated by the constant exchange of gluons, it would be mediated by the physical entanglement of these twisted tubes. Are these the “Flux Tubes” being described by many Physicists today? When only two twisted tubules are entangled, a meson is produced which is unstable and rapidly unwinds (decays) into something else. A proton would be analogous to three twisted rubber bands becoming entangled and the "Quarks" would be the places where the tubes are tangled together. The behavior would be the same as rubber balls (representing the Quarks) connected with twisted rubber bands being separated from each other or placed closer together producing the exact same phenomenon as "Asymptotic Freedom" in protons and neutrons. The force would become greater as the balls are separated, but the force would become less if the balls were placed closer together. Therefore, the gluon is a synthetic particle (zero mass, zero charge) invented to explain the Strong Force. The "Color Force" is a consequence of the XYZ orientation entanglement of the twisted tubules. The two twisted tubule entanglement of Mesons is not stable and unwinds. It takes the entanglement of three twisted tubules to produce the stable proton. The term “entanglement” in this case is analogous to three twisted ropes being wrapped around each other in a way which causes all of the ropes to move if someone pulls one of the ropes. Does the phenomenon of “Asymptotic Freedom” provide evidence that this concept is the correct interpretation of the experimental data now available? Can the phenomenon of "Supercoiling" help explain the "Multiple Generations" of particles in the Standard Model? The conversion of twist to writhe cycles is well understood in the structure of DNA molecules. Can the conversion of twist to writhe cycles and vice-versa help explain "neutrino oscillations"? Within this model neutrinos are a small, twisted torus produced when a tube becomes overtwisted and breaks producing the small, closed loop of twisted tube (neutrino), and a twisted tube open on each end, which is shorter than the original. (Beta Decay)
    Within this subatomic model gravity is produced by a very small higher dimensional curvature imbalance within atoms, which causes all atoms to be attracted to all other atoms. This extremely weak attraction reveals the very small scale of the curvature imbalance. This produces the curvature of spacetime on a larger scale like the solar system which is required to counterbalance this small imbalance in the individual atoms.

    Suppose we allow for a vacuum that is simply dispersed electrons that seem like neutrons within their buffer?

Maybe that could explain the gyrating motion instead of virtual photons.

    The size of an electron: is it really a mystery?
    No, it can be explained very simply but precisely by a classical model. According to this model, the electron is made up of two charges orbiting each other at the speed of light. The mass of the electron is not intrinsic, but results from the configuration by a fundamental process.
    This classical model explains all the particle's properties precisely, without any use of QM. For example, the precision for the mass is almost 10^-6 (unlike the Higgs, which gives us no value at all). It explains the spin and the magnetic moment exactly. It explains the g-factor with the same value as the Schwinger result. It explains the Lamb shift. It explains the energy-frequency relation instead of postulating it as QM does. And much more.
    Then the size of the electron is well defined. It follows from this model as 4*10^-13 m. The same as Erwin Schrödinger calculated in his well-known 1930 paper.
    How much do we really need QM?

      Gravitation and the electromagnetic force both have an 1/r dependence with vastly different factors. They can never cancel out.

Those two forces have very different dependencies on distance.

All the positrons in the universe could be part of such an arrangement, but if all the positrons were part of a single such arrangement, you'd need additional electrons that never switched directions.
