Fundamental J. Modern Physics, Vol., Issue 1, 11, Pages 73- Published online at http://www.frdint.com/ FRACTAL PHYSICS THEORY - NEUTRINOS AND STARS BASF Dispersions and Resins Monaca, Pennsylvania USA Abstract This fifth and last article of the series applies Fractal Physics Theory to neutrinos and stars. A wealth of data has been amassed and significant theoretical progress has been made during the past 4 years centered on detecting and understanding solar neutrinos. The fractal nuclear antineutrino emission process is modeled after quantum scale stellar emission. The absorption and emission of antineutrino energy by stable nuclei and atomic electrons is discussed. Stable nuclei and atomic electrons are at lower lilliputian scale temperatures than decaying nuclei emitting antineutrino energy, consequently, stable matter absorbs relatively high subquantum scale frequency photons and emits relatively low subquantum scale frequency photons in increased numbers so that the total antineutrino energy remains constant. 1. Introduction The first four articles of the Fractal Physics Theory series provide essential background information [1-4]. Fractal Physics Theory (FPT) proposes that most stars are cosmic scale nuclei undergoing cosmic scale beta decay. This cosmic scale nuclear beta decay is argued to occur exactly as nuclear beta decay occurs, the appearance of which differs because of the direction humans look up to larger scales or down to smaller scales of the Fractal Universe. Neutrinos and antineutrinos both arise during quantum scale nuclear fusion and as such are considered to be similar. The totality of a star s radiated energy (electromagnetic Keywords and phrases: fractal physics, neutrinos, starlight, subquantum.

74 radiation plus neutrinos) over its nuclear burning lifetime comprises one cosmic scale antineutrino. The vast majority of electromagnetic radiations are part of cosmic scale antineutrinos. Familiar antineutrino energy is observed by the lilliputian scale (ls) as electromagnetic radiation and neutrinos. The Sun s energy that constantly bathes the Earth is part of a single cosmic scale antineutrino. It is not so much a matter of seeing an antineutrino as to see with fractal antineutrino energy. Likewise, an antineutrino is the result of an ever spreading sphere of subquantum scale (sqs) photons, which are not in phase, and include a wide range of sqs-frequencies. Antineutrinos in FPT continuously delocalize as they propagate; this differs markedly from antineutrinos described by Modern Physics. A typical star like the Sun is expected to shine in its current state for about 9 billion years (Figure 1), which the titanic scale (ts) measures as 75 ns [1]. A fractally self-similar qs-sun radiates for 75 ns relative to the human scale and 9 9 1 y relative to the lilliputian scale. An antineutrino moving at the speed of light for 75 ns travels 5 m in the human scale. This nuclear radiated antineutrino is a spherical pulse 5 m in thickness and composed of a great multitude of sqs-photons and sqs-neutrinos. The spherical shell expanding in matter encounters atoms. The nuclei and electrons of the atoms encountered systematically alter the antineutrino energy. Figure 1. Cosmic scale antineutrino emission (typical shining star).. Antineutrino Quantum Scale Absorption The sqs-photons of relatively high sqs-frequencies comprising the single antineutrino are absorbed by the exposed surfaces of the nuclei and the electrons they encounter. These qs-black bodies reradiate all absorbed sqs-photons spherically from their surfaces, at longer sqs-wavelengths and increased sqs-photon numbers. This spherically radiated cooled sqs-radiation has a net effect, over relatively short
FRACTAL PHYSICS THEORY - NEUTRINOS AND STARS 75 distances, of redirecting about half the number of sqs-photons absorbed from the antineutrino expanding shell s initial path. The energy of the antineutrino is initially and continually reduced as it travels short distances ( < 1 cm) through matter. This is similar to Beer s law in analytical chemistry which relates the absorption of electromagnetic radiation traveling through a dilute solution to properties of the solution. However, antineutrino energy is not expected to be reduced when traveling through relatively large volumes of matter. The net effect of continued absorption and emission of antineutrino energy by large volumes of stable matter enables all the transformed antineutrino energy (sqs-photons of lowered sqs-frequencies and increased numbers) to escape the matter. Antineutrino absorption: A ν = abc, (1) A = absorption of antineutrino energy by matter, ν a = atomic surface area exposed to incoming antineutrino energy, b = radial path length traveled by antineutrino energy through matter over short distances, c = atomic number density, d* 1 * N A ( MW ), 3 d = matter density ( kg m ), N = Avogadro s number ( 6.1415 1 ), A MW = molecular weight. Atomic nuclei and electrons are considered as spheres with surface area 4π R. The expanding neutrino energy shell impinges upon half of the sphere s surface area it encounters. Atomic surface area exposed, a = (# of atomic electrons)(.5)(electron surface area) + (.5)(nuclear surface area). 1 3 a = ( Z ) ( πre ) + π( 1.fm A ), () Z = atomic number of the neutral atom, A = atomic mass, 17 R e = electron s radius ( 7.314 1 m ). 3

Uranium 35 dioxide ( 17 ) a U35 = 9* π 7.314 1 m + π[( 1. 1 15 m ) ( 35. 4393) 1 3 ] 3 = 3.1 1 m + 3.4459454 1 m = 3.4761736 1 m = 3.476 b, ( 17 ) a O16 = * π 7.314 1 m + π[( 1. 1 15 m ) ( 15. 994915) 1 3 ] 31 9 =.654 1 m + 5.7437693 1 m = 5.77547 1 9 m =.577 b, a UO = 3.476 b + *.577 b = 4.63 b, Density 3 = 197 kg m [5], MW = 67.3376. When the initial antineutrino energy is completely absorbed, A ν = 1., and the path length b, can be calculated. b = 1 ( a c ) = 1 [( 4.63 1 m ) ( 1.97 1 UO UO 7 g m 3 * N 67.3376)] =.73 m. A single nucleus emitting an antineutrino during beta decay within a solid mass of Uranium 35 dioxide will have its initial antineutrino energy completely absorbed by ambient atomic surfaces within a sphere of radius A.73 cm centered on the decaying nucleus. The nuclear and electron surfaces that absorb the initial antineutrino energy as relatively high sqs-frequency photons immediately reradiate this antineutrino energy as relatively low sqs-frequency photons in increased numbers. A beta decaying process lasting energy at a constant rate. At the end of shell 75 ns continuously emits antineutrino 75 ns, the antineutrino will be a spherical 5 m constant thickness increasing in size at the speed of light. As long as the decaying nucleus is within a large and dense enough mass, the resultant ever expanding antineutrino shell will be composed of the relatively lower sqs-frequency photons.
FRACTAL PHYSICS THEORY - NEUTRINOS AND STARS 77 3. Antineutrino Quantum Scale Emission The totality of all photons emitted from a star s surface comprises about 9% of the energy of a single cosmic scale antineutrino. The remaining % of energy is emitted from the star as neutrinos. Stellar surface temperatures range from < 35 K to > 5 K. These temperatures are converted to their self-similar lilliputian scale stellar surface temperatures using the temperature scaling fractal [1]: T 14 =.175 1 = [ star, surface temperature] 1, [ star, surface temperature] 1, Nuclei in the process of beta decay have surface ls-temperatures, relative to the human scale, in the range 17 1 < 1.6 1 K to > 1.14 1 K, which is also the lstemperature range of antineutrinos. It has also been proposed that the surfaces of stable cosmic scale nuclei and atomic electrons are in thermodynamic equilibrium with the microwave background radiation of temperature =.75 K []. The self similar subquantum scale microwave background radiation has a ls-temperature 14 = 1.46 1 K, which is the ls-temperature of the vacuum of atoms.

The self-similar local cosmic microwave background radiation is essentially the Sun s reflection off of many ambient liquid Helium mirrors. 4.

Neutrino Subquantum Scale Electromagnetic Radiation Spectrum The Sun emits electromagnetic radiation approximately as Planck s radiation law; therefore the majority component of neutrino energy is modeled with a lilliputian scale (ls) version of Planck s radiation law. Fractal Planck's radiation law: 5 x 1 [ I ( λ, T )] = A[ λ] ( e 1), (9) m, n [ I ( λ, T )] = scaled intensity radiated per unit λ at a given T, A = πc [ h], m, n x = [ h] c ([ λ] [ k] [ T ] ), m, n m, n m, n m, n [ h ], = scaled Planck constant, [ λ] m, = scaled wavelength, n [ k ], = scaled Boltzmann constant, [ T ], = scaled temperature, m = object scale location, n = observer scale location. 5 x 1 [ I ( λ, T )] = A[ λ] ( e 1), (1), 3, [ I ( λ, T )], = ls-intensity radiated per unit λ at a given T, A = πc [ h], 3, x = [ h] c ([ λ] [ k] [ T ] ), 3, 3, 3,, 114 [ h ] = 1.47953 1 Js, 3,
6 [ λ ] 3, = sqs-wavelength, 94 [ k ] =.539796 1 J K, 3, [ T ], = ls-temperature, c = 997945 m s, e =.711. Equation 1 is used to generate data in Tables 6 and 7 at the lilliputian scale temperatures self-similar to.75 K and 57 K. Figures and 3 plot the data from Tables 6 and 7, respectively, for sqs-wavelengths versus intensity radiated per sqswavelength. At first glance the power densities listed in Tables 6 and 7 may appear startling high. However, this just reflects the minute scales of sqs-wavelengths, nuclear surface areas, and emission times involved.

Conclusion This fifth article of the series applies Fractal Physics Theory to neutrinos and stars. Several human scale radiation equations are generalized to scale, while the lilliputian scale radiation equations are used to model neutrino emission.
