## Aether Structures

As we look into atomic structure, it becomes apparent that Linus Pauling's Spheron Model[15] accurately describes the fill pattern of atomic nuclei. The fill pattern rests on a peculiar system of half-spin numbers. As it turns out, this system of half-spin numbers is the actual “numbering system” used by the Aether.

How can there be a half-spin numbering system in the Aether? Because human senses perceive that one subatomic particle occupies one unit of volume-time. However, subatomic particles cannot fill an entire Aether unit, which leaves three spin positions unaccounted for. The Aether unit divides into four portions of spin positions in forward time. Of these four spin positions, only two occur in left hand spin, meaning there are only two possibilities for stable matter, the electron, and proton. Each spin position has exactly half-spin.

It is the half-spin subatomic particle per Aether unit, which distorts physical structures relative to Aether structures. This distortion is apparent wherever Aether interacts directly with subatomic particles. The logarithmic scale is a direct result of the interaction between half-spin subatomic particles and Aether (although one-spin photons also cause a distortion with regard to Aether).

The left hand spin characteristic of stable subatomic particles support Tsung Dao Lee and Chen Ning Yang’s violation of parity theory[8]. The left-hand-only spin characteristic of subatomic particles appears when free electrons eject during beta decay or when streaming as free electrons in a current. In electrostatic binding or magnetic charge binding, the subatomic particles are moving toward each other and spinning in opposite directions and so exhibit both left hand and right hand spins.

The Aether further evidences a preferred spin direction as observed in the asymmetry of matter/anti-matter existence. Nature does prefer matter to anti-matter[16], at least in our part of the Universe. The Aether Physics Model attributes this apparent preference to the gravity repulsion effect of matter to anti-matter. Matter and anti-matter collide and produce photons when they encounter each other, but they gravitationally repel each other at a distance. The gravitational repelling effect is the antithesis of gravitational attraction. Since matter in our part of the Universe happens to be left-hand spin, and since for practical reasons there is no anti-matter within atoms or molecules, for purposes of quantifying material structure the Aether essentially is a two-spin-position unit.

The proton spin position is equal to half the Aether unit, plus ½ spin for the proton spin position itself. The electron spin position is equal to half the Aether unit, minus ½ spin.

\[\frac{y}{2} + \frac{1}{2} = proton\:spin\:position \tag{4.11}\]

\[\frac{x}{2} - \frac{1}{2} = electron\:spin\:position \tag{4.12}\]

And since the Aether units are polar aligned (negative is attracted to positive), the electron spin position could just as easily be thought of as half the Aether unit, plus 3/2-spin:

\[\frac{x}{2} + \frac{3}{2} = electron\:spin\:position \tag{4.13}\]

In the above image, the electron spin position represents by the blue loxodrome and the proton spin position is the red loxodrome. In either case, the electron and proton spin positions provide the only possibilities for real matter to anifest in our part of the Universe.

Since the electron and proton spin positions are part of the spheres of Aether, and since the Aether constant is equal to \(16{\pi ^2}\) \(\left( {4\pi \cdot 4\pi } \right)\), which implies the two spin positions are orthogonal to each other, we can assume that the proton and electron spin positions are also orthogonal to each other. The array determines the full range of spin positions available to a given number of Aether units.

\[G\left( {x,y} \right) = \frac{{x + 1}}{2} \cdot \frac{{y - 1}}{2} \tag{4.14}\]

In the above equation, x and y are integers representing the total number of proton and electron spin positions available for a given structure as viewed from the macro world.

Using the CreateMesh function of MathCAD, the Aether numbers can be surface plotted. When first investigating Aether numbers, we arbitrarily assumed a fixed mesh of 80 x 80. We also assumed that a complete cycle of data \(\left( t \right)\) would be half the odd whole number \(h\) times \(\pi \).

We have since found the above assumptions were incomplete. In nature, the mesh is infinite, being a perfectly curved surface. Also, at the quantum level there are five dimensions of volume-resonance, rather than our four dimensional macro perspective of volume-time. With the discovery of the electron binding energy equation for ground state electrons, the number of Aether units in five dimensions empirically induces as \(\frac{{\sqrt {{x^2} + 1} }}{2}\) reinforcing the notion that Aether structures have a spiral nature to them. It remains to mathematically prove this hypothesis.

Notice in the above image the shallow image (red) is 180º out of sync with the deeper half of the image (blue). The shallow half of the image appears to represent the forward time portion of the Aether structure and the deeper half the backward time portion.

Let us set the function of G to reflect Aether structures indicated by the variable 1s orbital electron radii in the electron binding energy equation:

\[G\left( {x,y} \right) = \frac{{\frac{{\sqrt {{y^2} + 1} - 1}}{2}}}{{\frac{{\sqrt {{x^2} + 1} + 1}}{2}}} \tag{4.15}\]

We will also change the mesh to be proportional to \(h\) by a factor of ten. This eliminates the distracting artifacts of different shapes caused by different proportions of \(h\) to the mesh. (Although different meshes may not apply to the quantum level, they may still have relevance to macro structures.) Consequently, we now see a nearly curved structure, which we imagine as perfectly curved. Because the mesh is now proportional to \(h\), all generated images will show the same proportion of “nearly curved” structure.

In the preceding two views of the Aether structures, we are looking down the time axis (z axis) of the Aether units. In the former view on the preceding page, the forward time portion is discordant with the backward time portion. In the latter view above, which modifies according to the electron binding energy equation, the two views are coordinated, which is why the blue image is not visible.

We can now view graphical representations of the ground state electron in each atom. We will also change our perception from four dimensions to five dimensions so we can see more detail of how quantum structures operate. Keep in mind that the pictures shown here are only static, two-dimensional representations of a dynamic, five-dimensional structure.

As the ground state electron structure grows in complexity, its proportion of minor radius to major radius spirals inward.

Whereas the mesh for quantum structures is infinitely smooth, that is not the case for macro structures. As atoms bind to produce molecules, and molecules bind to produce structures of greater complexity, the mesh becomes grainier. The patterns formed for a particular granulation will differ from others. The coarseness of the granulation is likely variable according to size, mass density, temperature, pressure, and other considerations.

## Granular Aether Structures

Our original investigation conducts as a general exploration of Aether structures for a mesh of 80 x 80. We provide this earlier view to show the general direction a more detailed analysis of macro Aether structure might follow.

Starting from a very simple data set, assume there is a space-resonance cluster containing \(\pi\) number of Aether units. We produce a contour graph of the spin positions in the Cartesian coordinate system. To see what the contour actually looks like we can examine this graphic, which represents the function of \(G\left( {x,y} \right)\) from three different angles within five-dimensional existence. This characteristic of the Aether demonstrates its orthogonality.

Image A is a view of the contour plot directly down the Z-axis (linear time axis) and looking at the X and Y-axis in a Cartesian coordinate system. Image B is from a different perspective in the same coordinate system and shows that the contour plot is a 3D image over time. Image C shows the same data set appearing as a curve from a position orthogonal to the time axis.

This representative view of the data demonstrates the orthogonality of the Aether. In other instances, the Aether appears to be electromagnetic from one view and mechanical from a different view. The Aether appears angular from one view and curved from another view. This is what we mean when we say the Aether has orthogonality.

Applying a range of \(-\pi \) to \(\pi \) to equation (4.14), the following contour data generates in the Cartesian coordinate system (it is the same as the image above).

Using the same equation, but applying it to a cylindrical coordinate system, the data appears as a spiral cone.

Now we will present the above image with a color map scheme so it will be easier to visualize the data. The bluer colors are deep and the redder colors are shallow. The deep blue represents an earlier time than the shallow red.

In the image below, the range is increased from \(\pi \) to \(\frac{{19}}{2}\pi \). In the cylindrical coordinate system, each full cycle of revolution is equal to \(2\pi \). By choosing the negative and positive values for a given range, we are essentially using twice the range. Thus by keeping units in multiples of \(\pi \) we always have a full cycle \(\left( {2\pi } \right)\) of data. Similarly, since we are viewing the Aether structures in the form of \(\frac{{x \pm 1}}{2}\) it is necessary for the numerator to be an odd integer if we are to get a whole cycle of data.

The angle of the image above does not change from the previous images and neither has the view angle of the few succeeding images (all images view looking down the Z-axis). The image below represents a range from \( - \frac{{19}}{2}\pi \) to \( + \frac{{19}}{2}\pi \).

The appearance of the flower pattern is interesting, but is not the object of this investigation. Changing the range from \( - \frac{{31}}{2}\pi \) to \( + \frac{{31}}{2}\pi \), the geometry completely changes while maintaining a similar order.

Now we begin to see the importance of our investigation of Aether structures. Although these images are number generated, they base on the proportion of Aether to half-spin onta. For the next image, the range is set for \( - \frac{{53}}{2}\pi \) to \( + \frac{{53}}{2}\pi \).

Six polygonal shapes are generated as Aether structures, ranging from 3-sided to 8-sided polygons. There are also a number of star shapes varying from 5 points to 13 points and more. The range of the following image was set for \( - \frac{{73}}{2}\pi \) to \( + \frac{{73}}{2}\pi \).

In all of the cylindrical coordinate images presented here, the red-orange colors represent a geometry facing the forward time direction, while there is also a similar but slightly different shape facing the backward time direction. The blue colors are the backside of the red shape. This 13-point star is just one of many stars generated in this sequence of Aether structures, including near perfect 5 and 7 point stars.

The shapes do not morph ceaselessly, however. Just as musical tones continually repeat as harmonics in logarithmically increasing octaves, the Aether shapes also repeat themselves, albeit in a mirrored type of manner. For the range of \( - \frac{{157}}{2}\pi \) to \( + \frac{{157}}{2}\pi \) this image appears:

However, the next image in the sequence for the range \( - \frac{{159}}{2}\pi \) to \( + \frac{{159}}{2}\pi \) mirrors the above image.

From here, the images repeat themselves. For example, the image determined by the range for \(\frac{{53}}{2}\pi \) is replicated in the range of \( - \frac{{105}}{2}\pi \) to \( + \frac{{105}}{2}\pi \).

The range for the next replication of the triangle is twice the previous triangle range base plus the current range base:

\[2 \cdot 53 + 105 = 211 \tag{4.16}\]

So the next range that will produce the triangle would be \(\frac{{211}}{2}\pi \).

Going back to the two consecutive images that mirror each other, \(\frac{{157}}{2}\pi \) and \(\frac{{159}}{2}\pi \), the image in between must represent the “maximum” of the overall image cycle. This is the point where the progression of the images reverses itself. The image for the exact range of \( - \frac{{158}}{2}\pi \) to \( + \frac{{158}}{2}\pi \) takes on a completely different form than the slightest departure from \( \frac{{158}}{2}\pi \).

The above image is a very precise crossing point, providing evidence for the reality of the Aether structures. In other words, the Aether structures presented here are not a fantasy of numerology and pictures; this presentation represents a very real geometrical cycle of half-spin subatomic particles and Aether units.

As it turns out, the value 158 is very close to the Aether geometrical constant of \(16{\pi ^2}\) (157.914). The surface plot for the range using \(16{\pi ^2}\) instead of 158, \( - \frac{{16{\pi ^2}}}{2}\pi \) to \( + \frac{{16{\pi ^2}}}{2}\pi \), is shown below:

The above image views from the same angle as the previous image. Another view made by rotating the \(16{\pi ^2}\) data presents the image in the shape of an eye.

The eye is a fitting symbol for the \(16{\pi ^2}\) Aether geometrical constant, which is already associated with the dynamic and living Aether unit. As a side note, the ancient Egyptians and modern Freemasons use the “all-seeing eye” as a symbol for God. In fact, the all-seeing eye appears on every American dollar bill, over a pyramid.

Just for fancy, the Aether numbers applied to the spherical coordinate system can produce reflecting pyramids, too. The image below is produced in the spherical coordinate system with the range base of \( \frac{{41 \cdot 105}}{2}\pi \):

When \(16{\pi ^2}\) is applied to the surface plot, it gives a slightly different value than when 158 is applied. The ratio of the Aether half-spin value to the Aether constant value is the offset.

\[\frac{{\frac{{158}}{2}\pi }}{{\frac{{16{\pi ^2}}}{2}\pi }} = 1.00055 \tag{4.17}\]

We see an offset wherever the Aether interfaces with half-spin onta. For example, the offset of the subatomic particle with regard to the Aether is the subatomic particle g-factor. The offset of the Aether-based Pythagorean scale of music and the physical tempered scale of music is the tempered semitone[17]. Undoubtedly, there are other examples.

Whether or not there is a direct relationship, it is interesting to note that the Aether structure offset is approximately equal to the square root of half the electron g-factor:

\[\sqrt {\frac{1}{{\sin \left( {Phi} \right)}}} = 1.00056 \tag{4.18}\]

where Phi is the Golden Ratio and the g-factor equation is that of the Aether Physics Model (page 170).

Just as octaves increase logarithmically in the tempered music scale, the Aether structures also increase logarithmically, further establishing the reality of the structures. In the Aether structure series, \(\frac{{158}}{2}\pi \) is an exact “octave.” Each successive “octave” calculates by the formula \(\frac{{{2^x} \cdot 158}}{2}\pi \) where x is the number of octaves ascending from the base octave of zero. (The word “octave” does not truly apply to Aether structures since there are more than 8 “whole tones” in each octave; here it indicates a complete set of steps within a cycle). To illustrate that each octave of produces the same image, see the random octaves below:

\(\frac{{{2^2} \cdot 158}}{2}\pi \) | \(\frac{{{2^5} \cdot 158}}{2}\pi \) | \(\frac{{{2^9} \cdot 158}}{2}\pi \) | \(\frac{{{2^11} \cdot 158}}{2}\pi \) |

The world comprising human experience has many variations in form. But within these forms we see patterns. Flowers tend to have petal or spike patterns, as seen in the above graphics. Flowers even seem to reflect the Fibonacci sequence, which is also a manifestation of Aether numbers. Seashells and other exoskeletal creatures tend to have the shapes found in Aether structures when applied to the spherical coordinate system. The bell pepper, seeds, and numerous other shapes model after Aether structures in the spherical coordinate system. So the world of seemingly infinite form is really a symphony of shape, repeating at various octaves, sometimes harmoniously, and sometimes not.

These forms originate in the independent nature of Aether units. After examining Aether units with respect to half-spin subatomic particles, it is very easy to see how the physical Universe can have so much variety in all its forms. Yet it is quite remarkable that all the variations of forms that we see arise from just two discrete subatomic particles, the electron and proton, and their relationship to the Aether.

## Golden Ratio

Below is a table showing the progression of the square root of Aether numbers. Notice the product of the proton and electron spin position numbers equal an even interval of ¼. The curvature of Aether implies that the “quarter phases” refer to a cycle. The implication is that a full cycle consists of 5 Aether units. It is likely that there is a trigonometric connection to the Aether numbers. Notice that zero has a real place in this progression.

The electron and proton spin positions, which determine the structure of the physical world, have both a \(Phi\) and a \(phi\) component. We could think of these components as square roots, but they are square roots within the Aether structure. Both \(Phi\) and \(phi\) are series numbers and generate by the formulas:

\[\frac{{\sqrt x + 1}}{2} = Phi \tag{4.19}\]

\[\frac{{\sqrt x - 1}}{2} = phi \tag{4.20}\]

In equations (4.19) and (4.20), the variable x denotes as the sequence number of Aether units. It is here that we learn from the Aether something very telling. When five Aether units make up a cycle, \(Phi\) is the Golden Ratio and \(phi\) its inverse.

\[\frac{{\sqrt 5 + 1}}{2} = 1.61803398874989 \tag{4.21}\]

\[\frac{{\sqrt 5 - 1}}{2} = 0.61803398874989 \tag{4.22}\]

Whereas the product of \({Phi}\) and \({pPhi}\) give the phase of the cycle, the sum of \({Phi}\) and \({phi}\) give the square root of the sequence. This explains why \({Phi}\) and \({phi}\) show up continually in the physical world, wherever growth occurs and living forms appear. Growth occurs in cycles, and therefore we would expect the cycles to reflect the Fibonacci sequence.

There are many good sources of information about the Fibonacci sequence and its appearance in living and growing systems. If the reader is not familiar with the Fibonacci sequence, Internet web sites can give an introduction. A good place to start is

The Golden Ratio: The Story of Phi, The World’s Most Astonishing Number by Mario Livio is also a good read.

## Pythagorean Concepts

The Aether numbers also determine harmony in music. Pythagoras gets credit for developing a scale of tones still known as the Pythagorean scale[18]. However, other sources indicate the Pythagorean scale may have originated much earlier. Little information about Pythagoras exists, but there are accounts that he either learned directly from the Egyptians or else from the students of Thales. Thales himself learned geometry from the Egyptians.

Beginning with the discovery that the relationship between musical notes could be expressed in numerical ratios, the Pythagoreans elaborated a theory of numbers, the exact meaning of which is still disputed by scholars. Briefly, they taught that all things were numbers, meaning that the essence of things was number, and that all relationships — even abstract ethical concepts like justice — could be expressed numerically. They held that numbers set a limit to the unlimited — thus foreshadowing the distinction between form and matter that plays a key role in all later philosophy[19].

There are many today who believe that mathematics is only a language, and that mathematics of itself does not reflect reality. With regard to calculus, they are probably correct. Electrons and protons are primary angular momentum and the basis of all physical matter, but the spin positions taken by this primary angular momentum are purely numerical. Thus, it is possible for a physical entity to have a numerical representation via its spin position.

Using the subatomic particle spin positions of the Aether, a relationship of harmonic notes emerges. From this relationship, it is possible to calculate the next note up or down the musical scale relative to a reference frequency.

The basis of the formula is the musical fifth, as taught by Pythagoras. If we take a guitar string and place a bridge at the middle, the string on both sides of the bridge produces the same note. This is unison and its ratio is \(1:1\). When we place the bridge so that the ratio is \(\frac{1}{2}\), the two resulting notes are one octave apart. The next division of the string is the ratio \(\frac{3}{2}\). In this case the notes produced, one on either side of the bridge, are a fifth apart from each other. The fifth, having a ratio of \(\frac{3}{2}\) becomes a constant, which produces each succeeding fifth.

Let us assume we wish to find the fifth to a note, which we will specify as C at the frequency of \(523.25Hz\). C can be expressed in terms of fifths as \(\frac{{{3^0}}}{{{2^0}}} \times 523.25Hz\), which equals \(1 \times 523.25Hz\) or \(523.25Hz\). To calculate the fifth to C, which is G, we multiply \(\frac{{{3^0}}}{{{2^0}}} \times \frac{{{3^1}}}{{{2^1}}} \times 523.25Hz\). When multiplying exponentials we add the exponents, and so the formula becomes \(\frac{{{3^{0 + 1}}}}{{{2^{0 + 1}}}} \times 523.25Hz\) or \(784.88Hz\).

To calculate the value of the second fifth above C we follow the same procedure, except that we multiply by \(\frac{1}{2}\) in order to acquire the value of the D that is in the same octave as the initial C. Hence \(\frac{{{3^0}}}{{{2^0}}} \times \frac{{{3^1}}}{{{2^1}}} \times \frac{{{3^1}}}{{{2^1}}} \times \frac{1}{{{2^1}}} \times 523.25Hz\) which is the same as \(\frac{{{3^2}}}{{{2^3}}} \times 523.25Hz\) or \(588.66Hz\). Using the above method, computation of ratios for each note relative to C result:

\( \textrm{C}\) | \( \textrm{C#}\) | \( \textrm{D}\) | \( \textrm{D#}\) | \( \textrm{E}\) | \( \textrm{F}\) | \( \textrm{F#}\) | \( \textrm{G}\) | \( \textrm{G#}\) | \( \textrm{A}\) | \( \textrm{A#}\) | \( \textrm{B}\) |

\(\frac{{{3^0}}}{{{2^0}}}\) | \(\frac{{{3^7}}}{{{2^{11}}}}\) | \(\frac{{{3^2}}}{{{2^3}}}\) | \(\frac{{{3^9}}}{{{2^{14}}}}\) | \(\frac{{{3^4}}}{{{2^6}}}\) | \(\frac{{{3^{11}}}}{{{2^{17}}}}\) | \(\frac{{{3^6}}}{{{2^9}}}\) | \(\frac{{{3^1}}}{{{2^1}}}\) | \(\frac{{{3^8}}}{{{2^{12}}}}\) | \(\frac{{{3^3}}}{{{2^4}}}\) | \(\frac{{{3^{10}}}}{{{2^{15}}}}\) | \(\frac{{{3^5}}}{{{2^7}}}\) |

When we give our starting point a variable instead of the note \(C\), a simple equation results for calculating the frequency \((F)\) of any note relative to another frequency \((K)\), where \(n\) is equal to any integer representing the number of notes to increase or decrease from the reference frequency:

\[F = K\frac{{{3^n}}}{{{2^{\left( {n*\frac{3}{2}} \right)}}}} \tag{4.23}\]

It is easy to see that octaves increase logarithmically, just as do the Aether numbers of form. Figuring for the frequency of \(440Hz\), the succeeding octaves are equal to \(n = 12\), \(n = 24\), \(n = 36\), etc.. The resulting frequencies are \(880Hz\), \(1759.67Hz\), and \(3518.02Hz\). The calculations are not exact due to the rounding of exponentials.

#### Pythagorean Triples

A Pythagorean triple is a triple of positive integers \(a\), \(b\), and \(c\) such that a right triangle exists with legs \(a\), \(b\), and hypotenuse \(c\). By the Pythagorean Theorem, this is equivalent to finding positive integers \(a\), \(b\), and \(c\) satisfying \({a^2} + {b^2} = {c^2}\).[20]

When I was a student in high school, my math teacher, Mrs. Connie Kimball, gave a lecture on calculating Pythagorean triples. The method she described on the blackboard was long and tortuous. Almost immediately, I recognized a pattern in the table of Pythagorean triples that she had written, and I started working on a different equation than the one she was showing.

Recognizing that I was busy in my own world while she was lecturing, she curtly called me, as teachers do when they think someone is not paying attention. She asked if I could explain what she had just said. I told her I could not, but that I had found a new equation for generating Pythagorean triples that was far simpler than what she was teaching.

Seizing on the moment to teach me a lesson, she called me to the front of the class to give a demonstration of my equation. When I finished my brief presentation, she was quite impressed. She asked me to stay after school and help her see if such an equation could be found in the professional literature. After a couple of days, we found that Joe Roberts from the Massachusetts Institute of Technology had published the same equation in a mathematics journal just 9 months earlier. It was at this time that I realized there was much left to be discovered in the worlds of math and science.

Here is the equation I had discovered for Pythagorean triples during class that day. For any integer \(a\), the other two values \(b\) and \(c\) are:

\[\begin{array}{l} b = \frac{{{a^2}}}{2} - \frac{1}{2} \\ c = \frac{{{a^2}}}{2} + \frac{1}{2} \\ \end{array} \tag{4.24}\]

A table of Pythagorean triples then generates:

\(a = \) | \(\frac{{{a^2}}}{2} - \frac{1}{2} = \) | \(\frac{{{a^2}}}{2} + \frac{1}{2} = \) |

\(2\) | \(1.5\) | \(2.5\) |

\(3\) | \(4\) | \(5\) |

\(4\) | \(7.5\) | \(8.5\) |

\(5\) | \(12\) | \(13\) |

\(6\) | \(17.5\) | \(18.5\) |

\(7\) | \(24\) | \(25\) |

\(8\) | \(31.5\) | \(32.5\) |

Pythagorean triples cannot have fractions, so for all values of “\(a\)” that are even, two multiplies the full set. The resulting table then appears as:

a |
b |
c |
---|---|---|

4 |
3 |
5 |

3 |
4 |
5 |

8 |
15 |
17 |

5 |
12 |
13 |

12 |
35 |
37 |

7 |
24 |
25 |

16 |
63 |
65 |

9 |
40 |
41 |

20 |
99 |
101 |

The relevance of Pythagorean triples to the Aether numbers is the form of the equation. The equations for \(b\) and \(c\) express as in the table below.

In (4.25), the value \(a\) is the integer value of the Aether numbers, and the values \(b\) and \(c\) are the half-spin onn values based on the square of \(a\). Therefore, in addition to the Golden Ratio and growth cycles, it appears we also find the origin of the Pythagorean triples in the Aether.

Certainly, the forms of living and growing things represent numerically whether or not “ethical concepts like justice” do. The Aether Physics Model is consistent with the work of Pythagoras, which itself merits a re-evaluation in this light.

\[\begin{array}{l} b = \frac{{{a^2}}}{2} - \frac{1}{2} \\ c = \frac{{{a^2}}}{2} + \frac{1}{2} \\ \end{array} \tag{4.25}\]
