Atmospheric Refraction and Ether

"If the only tool you have is a hammer, you tend to see every problem as a nail."

Abraham Maslow

The Speed of Light and Ether

The Hafele-Keating experiment demonstrates that the "density" of ether varies by

altitude. Because ether is a medium for light, one might wonder whether the

speed of light also varies by altitude. I believe it does, however, determining this

using atomic clocks would be extremely tricky because the "time" measured by

atomic clocks also varies by the density of ether and thus by altitude, thus a

person would have to isolate whether the "speed of light" variation was due to a

difference in the speed of light or a difference in the speed of the atomic clocks

(i.e. a difference in the "time" registered by the atomic clocks at a higher altitude).

While it is well known that sound (a wave) travels faster through denser

mediums, sound is a physical bumping, and light is an electromagnetic bumping,

thus the properties of sound are not necessarily the properties of light.

Nevertheless, there are two experiments or phenomenon that do indicate that not

only does the speed of light vary by altitude (i.e. density of ether), but that in the

denser ether the speed of light is faster.

Atmospheric Refraction

"Atmospheric refraction" is a type of aberration caused by the refraction of light

as it passes through our atmosphere. It is most pronounced on the horizon, but

is in affect everywhere except the zenith. It is generally believed that this type of

aberration is caused by the air in the atmosphere refracting light (i.e. hence its

name: "atmospheric" refraction). This is somewhat logical, but ether provides

another answer.

If the speed of light is faster in a denser medium of ether (as would logically be

expected), then as a light ray from the sun got closer to the earth, the speed of

light would increase.

Let us represent one thin slice of a layer of ether density of ether drag by a thin,

hollow sphere that surrounds the earth, with its center at the center of the earth,

134

and where the boundary of the sphere is 10,000 kilometers above the surface of

the earth. Now let us consider that the light from the sun is 5 degrees above our

horizon. When this ray of light hits the imaginary sphere that we have

constructed in our minds, let us consider a 2D plane that is tangent to our

imaginary sphere at the point where this ray of light hits the sphere. Now let us

consider a vector that is normal to the tangental plane and passes through the

center of the earth.

Snell's Law states that when a beam of light hits the boundary of two substances,

which carry light at different speeds, and if the light is moving from the medium

which offers a slower speed of light into the medium which offers the faster

speed of light, the light will bend in a direction away from the normal vector.

However, it is well known in astronomy that the light actually bends towards the

normal vector.

This, of course, is exactly the opposite of what Snell's Law would predict if the

speed of light is faster in denser ether. There are several ways to explain why

the result is not what would be expected.

1) The speed of light is actually is slower in the denser medium.

2) Atmospheric refraction is actually caused by two factors, which have opposite

effects, one being the atmosphere and the other being ether, with the

atmospheric component being the more dominant of the two.

3) The speed of light is the same in all densities, and all of atmospheric refraction

is caused by the atmosphere.

Personally, I don't like any of these explanations. However, there is one

explanation I do like.

Let us consider Snell's Law with respect to air and water. Air and water are

called "mediums" for light when discussing Snell's Law, as I did above. This is

not true. Air and water are "obstructions" to light, not mediums for light. Only

ether is a medium for light. Air and water are obstructions. Thus, Snell's Law

basically states, that when light travels from one "lesser obstruction" (lower

index of refraction) to one "greater obstruction" (higher index of refraction), the

light will bend in the direction of the normal vector.

Ether, however, is the one and only true "medium" for light. Thus, we might

have a modified Snell's Law for use where there is no significant obstruction, only

pure medium involved: "When light travels from one "lesser [dense] medium"

(i.e. slower light, viewed from the aspect of the true medium, not an obstruction)

to one of "greater [dense] medium," the light will bend in the direction of the

normal vector.

Since ether is a "catalyst" for light, not an obstruction, this make logical sense.

The denser ether is the path of least resistance and the light would favor the path

135

of least resistance. This is especially true since the density differences are very

gradual, not abrupt. Nevertheless, logic is not the determining factor.

"Logic is a system whereby one may go wrong with confidence."

Charles F. Kettering

I call the actual bending of light by different layers of ether drag density (towards

from the normal vector) the: "Density of Medium Law." Whether the Density of

Medium Law exists or not will have to be determined by experiment at some time

in the future.

The Bending of the Light of Jupiter Occultations

If the Density of Medium Laws were true, wouldn't occultations of light near

Jupiter bend the light of the stars significantly. Yes, but we would not see this

bending from where we are. This is because the Density of Medium Laws would

apply twice to the starlight that passes through Jupiter's ether drag. The first

time it would bend light down towards Jupiter, as it does on the earth. However,

our telescopes are not located on the surface of Jupiter. This means the light

would have to exit the ether drag of Jupiter in order to get to us (I don't know if

we are inside of Jupiter's ether drag, but probably not). This means the light

would have to go from the denser ether near the surface of Jupiter to the less

dense ether far from the surface of Jupiter. This light would bend in the

opposite direction of the first bend, offsetting the first bend. Thus, we would not

observe either bend because they offset each other.

In reality it is possible the light from Jupiter does bend very slightly, but certainly

not what would be expected from a single bend due to the Density of Medium

Laws. The second bend may not completely offset the first bend, if, for example:

the core of Jupiter may not be perfectly spherical, or the River Effect Laws may

play a part. I don't know.

The Bending of Light That Passes Near the Sun

Another question that might arise is whether the bending of light that passes next

to the sun is caused by the Density of Medium Law. First of all, I am not sure

that anyone has proven that light that passes next to the sun does bend. The

original experiment that claimed to detect this phenomenon was seriously flawed

and only coincidentally came up with the "right" numbers to support Einstein.

Nevertheless, assuming such is the case (due to far more modern experiments

of a different nature), since the earth is probably inside of the sun's ether drag, it

is possible that ether is what causes that phenomenon. Let me explain.

136

Unlike the case with Jupiter, where two bendings of light offset each other,

because we are probably inside the sun's ether drag, we would see the light

before it completely straightens out (by a second complete bending) after it has

passed near the sun's surface. In other words, the light actually bends twice, but

we see the light before the second bend completely offsets the first bend, thus

the net of the two bends (one completed and one incomplete) is a slight bend. I

do not necessarily claim this is the case, I simply mention that it might be the

case and explain how it might be the case.

Since we have been talking about two bends, it might be emphasized that in the

case of the earth's atmospheric refraction, the light bends the first time, but

because the person or telescope is sitting on the surface of the earth, the first

bending is observed before the second bend even begins.

The Speed of Light From Jupiter:

There is an experiment that measures the speed of light in the solar system. In

this case it is the measurement of the speed of light between Jupiter and the

earth.

Imagine that there are three people looking at Jupiter. Each of them has a watch

and all of their watches are synchronized. Person number one is stationary on

the path of the orbit of our earth, at the point where our orbit is closest to Jupiter

(at the instant the light leaves Jupiter). Person number three is stationary on the

path of the orbit of earth, at the point where our orbit is furthest away from Jupiter

(at the instant the light leaves Jupiter). Person number two is halfway between

the other two, which would be near the sun or possibly even inside of the sun.

Now consider the moment of time that a specific moon of Jupiter goes into the

shadow of Jupiter (or casts its shadow on Jupiter's surface). If light travels at an

infinite velocity all three people will observe the shadow at exactly the same time.

On the other hand, we know that if person #1 observes this phenomena at

1:00PM, that person #2 will observe it at about 1:08PM and that person #3 will

observe it at about 1:16PM. These, of course, are approximations.

Knowing that the orbits of the moons of Jupiter are constant and predictable,

scientists can measure the speed of light between Jupiter and the earth by

writing down the time that the shadow of Jupiter starts to cover this specific moon

(usually the moon Io) in its orbit. By calculating this time in many experiments,

each relative to where the earth is in its orbit, very accurate measurements of the

speed of light in our solar system can be determined.

Since the first of these experiments was done in 1676 by Romer, far better

computer models of the solar system have been built, and far better

approximations of the speed of light in our solar system have been calculated.

137

According to Ditchburn[29-page 301], the speed of light from Jupiter to the earth is

0.5% slower than the speed of light in a vacuum on the surface of the earth. On

the surface, this observation is an indication that the speed of light is faster on

the surface of the earth, than it is in space, meaning the speed of light is faster if

the ether is denser. But it is not quite as simple as that. Consider the following

problems in making such a simple assumption.

First, I do not know whether the 0.5% figure is accurate based on modern

equipment and modern celestial mechanics formulas. When was this data

collected? What figure would be arrived at today, using the best of astronomy

and celestial mechanics? I do not know.

Second, it is obvious that the sun creates its own ether drag, but we don't know

how far into the solar system its ether drag goes, thus we don't know the density

of the sun's ether drag between our earth and Jupiter, compared to the density of

ether on the surface of the earth, though the sun's ether drag between the Earth

and Jupiter is probably less.

Third, Jupiter also creates its own massive ether drag, but we don't know how

far into the solar system its ether drag goes (i.e. we don't know how close it gets

to us), or how dense it is between the two planets.

Fourth, the density of the ether drag of both the sun and Jupiter, varies

significantly according to the relative "altitude" from these objects. These figures

are not available.

Fifth, it is not known whether the speed of light on the surface of Jupiter is faster

or slower than the speed of light on the surface of the earth, all we know is the

density of the ether will be greater on the surface of Jupiter.

Nevertheless, in spite of all of the criticisms, it is reasonable that the average

density of ether between the surface of the earth and the surface of Jupiter, is

less than the density of ether on the surface of the earth. Thus it is logical to say

that the less the density of ether is, the slower is the speed of light, if the

experiment is verified.

Comments

There has been a considerable amount of speculation in this chapter and the

prior chapter. Most of the speculation is caused by experimenters not looking for

what I want them to look for, thus the data that I need does not exist in a form I

can use. The most important thing to remember from these two chapters is that

aberration of starlight undoubtedly occurs at the boundary of our ether drag.

Considering my two experiments on the path of light, it is absolutely

impossible that aberration occurs inside of the earth's ether drag, meaning

138

inside of the telescope. Aberration must occur long before the light gets to the

telescope.
