The Ten Axioms of Corporeal Field Theory
1. Space flows as inexorably as Time.
2. Space is compressed rather than curved.
3. Mass is the compression of Space.
4. Energy results from Space decompression.
5. Entropy measures Space decompression.
6. Matter consists of standing waves of Space.
7. Radiation consists of traveling waves of Space.
8. Space must be conserved with mass-energy.
9. Light waves are condensed photons.
10. Time is the Virtual crossproduct of Real Space.

Lighten Up
Now, back to ideas: It is a simple property of sinusoidal waves that they exhibit the same shape (periodicity) in both space and time. Once you can imagine how that can be expressed it becomes obvious. I have never seen it expressed except to show the same two two- dimensional graphs plotted as amplitude versus distance and amplitude versus time, that is just to change the name of the horizontal axis. But a pseudo-3D plot of these two axes perpendicular to each other, called an orthogonal projection, shows some interesting relations. We can color code the amplitude with red at the crest (maximum amplitude) and violet at the trough (minimum amplitude)using the rainbow sequence (ROYGBIV). The while lines are sine waves running parallel to each axis. The graph shows what looks like a corrugated sheet cut at 45 degrees to the bends. It also clearly shows that any point (height) on the wave moves at the velocity of the wave - which is any upward (vertical) line (same color) on the graph since distance/time=velocity.

What's the Time?
There are two types of quantities we are interested in: scalars which have a magnitude (think point), and vectors which have a magnitude and a direction (think arrow). There are two types of multiplications (products)of vectors (say A and B): the dot(scalar product: A . B =|A||B|cos(angle between the vectors)) and cross(vector product: A x B =|A||B|sin(angle between the vectors)) products. For the perpendicular axes we will consider the angles between the vectors as 90 degrees with the sin(90)=0 and the cos(90)=1. So all scalar products will zero and the vector products will equal 1|A||B| where |A| is the length but not the direction of A only, etc.. The vectors will be unit vectors with a length equal 1, so their only difference will be their direction. These directions are alternately labeled X or i, Y or j, Z or k. There is a good dscussion of the vector product on the web at SolitaryRoad.com (who invites email contact) and once again I got summarily ignored when I emailed him/her/it with what I thought was an interesting question (see below). Now the new thing I am ranting about is combining three Argand planes as described in Rant#6. Each of these planes are X vs. vX, Y vs. vY, and Z vs. vZ. each aligned to one of the three axes: X, Y, and Z. This somehow makes for six perdendicular axes in 3-dimensional space (not something you can visualize). The figure shows the Argand planes (recall that i has two usages with some confusion: i is the label of the unit X vector and also the imaginary quantity of the square root of minus one. This is why I chose to use X as the unit vector along the X axes and vX as the imaginary axis. The vis for virtual (and looks like the square root surd) and is the same as imaginary but less confusing than i and is perpendicular to X. The direction of the vector product is perpendicular to the plane of the two vectors involved in a right-handed sense. This is shown in the figure, it would be writen X x Y = Z but if the order of multiplying were reversed the result would be negative as Y x X = -Z.
Using these rules and noting the order and sign given by the circle in the figure, i x j=k and i x k =-j, we can construct a multiplication table in the order ROW VARIABLExCOLUMN VARIABLE. There are a couple of observations we can make about the table. First off, any axis is not perpendicular to itself, it's parallel with an angle of zero, so the sin(0)=0 and the cross product is zero. This accounts for the long (main) diagonal in the table. Second, and this is the question to SolitaryRoad.com, we have no knowledge of the cross product of a real axis with its imaginary (as in the Argand plane), I postulate that it is TIME as shown in the figure and in the Table in the diagonals in the upper left and lower right quadrants. The rest of the terms follow the |A||B|sin(90) rule.
| Variable | X | Y | Z | vX | vY | vZ |
|---|---|---|---|---|---|---|
| X | 0 | Z | -Y | t | vZ | -vY |
| Y | -Z | 0 | X | -vZ | t | vX |
| Z | Y | -X | 0 | vY | -vX | t |
| vX | -t | vZ | - vY | 0 | vZ | -vY |
| vY | -vZ | -t | vX | -vZ | 0 | vX |
| vZ | vY | -vX | -t | vY | -vX | 0 |
- X = 0 X + Z Y - Y Z + t vX + vZ vY - vY vZ = t vX
- Y = -Z X + 0 Y + X Z - vZ vX + t vY + vX vZ = t vY
- Z = Y X - X Y - 0 Z + vY vX - vX vY + t vZ = t vZ
- vX = -t X + vZ Y - vY Z + 0 vx + vZ vY - vY vZ = -t X
- vY = -vZ X - t Y + vX Z - vZ vX + 0 vY + vX vZ = -t Y
- vZ = vY X - vX Y - t Z + vY vX - vX vY - 0 vZ = -t Z
| Variable | X | Y | Z | vX | vY | vZ |
|---|---|---|---|---|---|---|
| X | 0 | 0 | 0 | t | 0 | 0 |
| Y | 0 | 0 | 0 | 0 | t | 0 |
| Z | 0 | 0 | 0 | 0 | 0 | t |
| vX | -t | 0 | 0 | 0 | 0 | 0 |
| vY | 0 | -t | 0 | 0 | 0 | 0 |
| vZ | 0 | 0 | -t | 0 | 0 | 0 |
vX = -t X becomes vX/v = -t X/v but 1/v = -v then X = t vX. In other words there are only 3 equations. Alternatively we could have started with the three equations in the real variables (X,Y,Z) and obtained the 3 equations in the form vX = -tX which is a bit more satisfying because this says that the three space (Cartesian) coordinates themselves are related to their imaginary counterparts and the negative of time. This in a sense is what Einstein established about the concept of "spacetime." That events can be separated by a Pythagorean like theorem in which the distance is given by the square root of (X^2+Y^2+Z^2-t^2) where the space coordinates are summed but the time coordinate is subtracted.
