What the bleeping bleep. I do not have a Wii but would like one until I saw the commercial for everyones favourite antivaxxer promoting her game for the console. This is diffently a minus for the Wii. Why did nintendo decide to give that no brain idiot be the front person for this new game.

Reblazing old trails
No I have not found a new job yet but I have busy. Right now spending time in the woods behind my home gathering tips. Tips are basically the tips of fir branches used in wreath making. This way a get some exercise maybe earn a little money and scout out our land that nobody has been on for about a decade. Besides that trying to learn web programming, split and piled five cords of wood and looking for a job.

Hubble’s Law
Hubble’s law states that galaxies are moving away from each other and the further apart
they are the faster they moving away. The acceleration that has been determined be 74.2
km/s/Mpc. That means for every Mega parsec(1million*3.26 light-years) between galaxies they
are moving apart at 74.2 km/s.
How was Hubble’s law found and used?
About ninety years ago there was an astronomer named Edwin Hubble. He took many images of
what were known as nebula. Some of these nebulas contained stars and some had Cepheid
variables. Cepheid variables are stars the change their brightness of a period of time. The
relationship between brightness and period is well known so if take images over an extended
amount of time you can figure out the period, after that you can figure out the maximum
brightness and figure out how far the galaxy is away. Hubble came to the conclusion that some of
the nebula were further away then what could be in our galaxy. At the same time there was a
group measuring the red shift of these nebula, Hubble compared the distances with red shifts and
found that further away the galaxies the faster they were travelling away from us. Since Hubble’s
time there have been at least one other way of finding distances that is type 1a supernovae. Type
1a supernova are large explosions created when enough mass is deposited onto a white dwarf.
After a while the white dwarf becomes unstable and there is a large explosion. The amount of
light decreases at predictable rate so they can be used similar to Cepheids.
Conclusions
The electric universe theorists claim there is no evidence support that the further a galaxy it is
however there is plenty of evidence to support it.

Light
The Preamble
During the first day of my first astronomy class the professor asked the class a question,
“when you look up at night what do you see?” Some said “stars, planets, moons”, and some idiot
that will not be named (me),”quasars”. “No, we see light” he responded. All the information we
get from a star is in its light. From the light of the star we get it’s temperature, what is made of,
the concentration of what is made of, and the mass.
What is light?
Light acts like a particle with no mass and also a wave. There is one experiment that can
demonstrate this and that is the Young double slit experiment. To set up this experiment you a card with
two slits in it, a light source shining through it and a screen opposite the light source. When
you run the experiment emitting one particle at a time over many times the pattern the many dots
make is the same interference as if a wave was going through the slits. At
Hitachi. These experiments both showed the wave-particle duality of the electrons. Light is also
the particle that conveys electromagnetic energy.
How is light generated?
Light can be generated by several different processes. One is nuclear reactions such as fission and
fusion, in either one of process happens a small portion of the mass converted to energy we
detect this energy in the form of light. Another way is when an electron which is orbiting around
the nucleus and then is excited by a photon (particle of light) and goes to higher orbit or leaves
the atom but the atom actually wants to be in lowest energy state so the electron will go back to
the lower energy level and admit a photon. When atoms are excited by thermal means, that
means the atoms move faster and faster, the atoms collide and electrons can be excited and as
before they want to be in the lowest energy level and the energy lost is seen as light.
What is the spectrum and how is created?
Take a prism and hold it to the sun get a rainbow coming out. The reason for this is that the
light from the sun is composed of all these colours and as they go through the prism they travel at
different speeds. We can only see a small part of the spectrum, there are X-rays, gamma rays and
UV light which have shorter wavelengths and are higher energy then we see, at the other end we
have infrared , microwaves and radio waves which are longer wavelength and lower energy.
There three different types of spectrum each dependent on what you are viewing. A
continuous spectrum has no lines and caused by a hot opaque, dense gas. An emission spectrum
is series of bright lines against a dark back ground and caused by a hot transparent gas. An
absorption spectrum is a series of dark lines against a background pf a continuous spectrum is
caused by the light from a source of a continuous passing through a cool transparent gas.
spectrum also come in a form of the intensity vs the wavelength.
How Do Astronomer’s use the Spectrum ?
There is gold in there light. First can determine what temperature an object is, this is
done by plotting the intensity (how strong) vs the wavelength. The plot you get for example for
the sun will have peak at 550 nm, this with a little math gives a temp of 5780 K. If you have an
emission or adsorption nebula you can determine what the object is composed. The orbits of
electrons around each type of element is slightly different so the energy needed to excite each
electron in different types of atoms or molecules is different. So if you know what the spectrum
for the various atoms or molecules you can figure out what the object is made of, some stars
show a spectrum of molecules and molecules break apart a fairly cool temperatures so these stars
must be cool, some stars show no molecules but show ionized atoms these stars are hotter
because the molecules have been broken apart.
Mass can be determined by the interaction of the object with other objects. When an
object moves away from the observer the light is shifted to the red end of the spectrum and when
the object moves closer the light is shifted towards the blue end. If there is a star where the
spectrum is shifted from the red and then to blue and does this one a regular period you can
determine the mass of the objects. This is also how most planets are found around other stars.
One claim by the electric universe proponents is that there is no connection to the mass and the colour of a star. Also all the light is generated on the surface of the star.
First most stars have an absorption spectrum and if the light was produced on the surface they would have an emission spectrum. There are some stars that have an emission spectrum but these are extremely hot stars and therefore the atmospheres are hot enough to ionizethe atoms. Second most stars in our galaxy are two or more stars that orbit around each other so there are plenty of stars of different types to see if there is correlation between mass and colour. Also smaller stars tend be cooler and more massive stars are hotter, so the less massive stars should have molecules
in there spectrum and larger stars shouldn’t have molecules in the spectrum. So scientists have found low mass stars that emit most of the light in the red part of the spectrum and have molecules in there spectrum while high mass stars emit most of there light in the blue part of the spectrum and have ionized atoms in the spectrum.
Conclusion
Light is a particle and a wave and conveys electromagnetic light. There is a lot of
information that can be found in the light that a star emits such as mass, temperature and
composition. We can show that there is correlation between mass, colour and temperature of a star.

Aether
Why discuss Aether?
Because the electric universe proponents try to dismiss special relativity by trying to
claim aether does exist therefore Einstein was wrong. Long before Einstein’s theory of special
relativity there was gathering evidence that aether was not there. As Sagan states in the Demon
Haunted World, it is not possible to prove something does not exists, in aethers case there is no
proof that demonstrates it does exists.
What is Aether?
This is not so simple because it meant different things to different groups. Aether meant to
the Greeks as “to burn, to kindle, or to shine” and it meant everything above the clouds. Newton
used it to help explain the refraction and diffraction in the particle theory of light Huygens used to
explain how light moved in a wave. Huygen’s claimed that light moved in longitudinal waves like
sound waves or mechanical waves. Eventually it turned into a substance that could do almost
everything at the same time. When Maxwell came along with his equations for electricity and
magnetism it came obvious that light travelled in transverse waves which means that the aether has
to be rigid. The only requirement for Maxwells equations for light to travel in a vacuum is must
travel at the speed of light. At lower energies the viscosity had to near null or it would cause drag,
and the planets would spiral towards the Sun. In the 1800’s experiments like Michelson-Morley
experiment showed no evidence of aether exists. Since then there have been several more accurate
experiments backing up these experiments.
What was the Michelson-Morley experiment ?
The Michelson-Morley experiment was to measure the effect of the aether on a light source
travelling on the Earth. If the Earth moves in the aether and the light is parallel to the motion of the
Earth around the Sun, it would effect the speed of light. The speed of light would be higher when
travelling in same direction as the movement of Earth around the Sun and would be less when the
light was travelling the opposite direction. The device was a light source that was passed through a
halved silvered at a 45 degree angle mirror thus splitting the light on straight ahead and one at 90
degrees. The whole apparatus was floated in pool of mercury so it could spin so it could change
orientations easily. At the end of each arm was a mirror and was reflected back to halved silvered
mirror and reflected to a detector. If the two beams of light were still travelling at the same speed
they would over lap each and constructively interfere each other. If one was slower then the other
there would be two peaks with one slightly behind the other. On the detector there would a pattern
of a bright dot in the centre and a series of concentric circles on the detector if there is aether and if
no aether there would be no pattern. There was a pattern but it was smaller then what was needed
and what was detected was less then experimental error and the era of aether was on it’s way out.
Were there any experiments that did not agree
There were a set of experiments done by Dayton Miller which showed aether may exists. Dayton Miller’s experiments were shown by Shankland to have errors. The apparatus itself was shown to be affected by thermal conditions also Miller’s results were actually averages of hundreds so they were 10 times smaller then could be measured by the device . So device could be influenced by temperature changes and the analysis was faulty.
Conclusion
So in summary, aether could exits but it has no effect on light or on matter that we can
measure with our current technology. Does this prove Einstein right, no. Is there other evidence for
special relativity, yes.

E Pur si mouve
400 years ago he pointed a telescope too the heavens, he might
of not been the first one to do so but he did more with it then others
at the time. Not only did Galileo find craters on the moon or find that
there are moons going around Jupiter or find that Venus has phases
like the moon or that there are spots on the sun. He did them all.
These things demonstrated that the heavens are not perfect and that
everything does not go around the Earth. He did even come up with
the idea, Copernicus did. Based on his and Tycho`s observations and
Kepler`s calculations Newton came up with the Law of Gravity.
One thing he did though is brought back is doing experiments to
learn new things. He rolled a ball down an incline plain and
measured how long it took, after many of these experiments to find
no matter how massive the ball rate the balls fall at the same rate.
Centuries later students in high schools and universities are doing
this same experiment. He was one of a few that started the modern
science movement, that still continues this day. There is a story that
during his trail he said “E pur si mouve” translated to “Yet it still
moves” referring to the movement of the Earth around the sun.
Rather or not he said does not really matter. The scientific movement
he help found is still going like the Earth around the Sun. So if it is
not for pointing the telescope to the heavens for the first time he should be celebrated for his other contributions to science as well.

Yet we still look up
In the distant past a hominid is looking over the fire up to the fires in sky wondering what they are. He and his tribe over time make stories about patterns they see in the sky. They realize that the patterns change at different times of the year, some are there during the rainy time some are there when there is no rain. Over time there are stories why the rain and some stars appear at the same time. Also they notice some of these fires move all over sky unlike the other fires these are called the wanderers by some. There is also a big light that comes out some nights and not in others and sometimes only part of the light comes up. Once and while the big fire during the day is covered and once and the light night at night turns red or black just for a few moments. During the passing of time people find out the some fires are brighter then others. Some try to use the stars to predict their own future.
After many dark years people look back at the stars. One man figures that the place lives on goes around the fire of the day so does the other wanderers. Another points a device that magnifies the light from the wanderers and finds one has four wanderers around it and one wanderer named Venus looks the light at night and shape changes over time. There is guy figures how the wanderers move around the day fire. Another figures there is force called gravity holding things together. He also discovers that if you take a prism that white light split into many different colours. Over the years people discovered that if you look at the light from different objects you got a different patterns of light. When people finally took the light from a telescope and let it pass
through a prism the found the spectra of different things there.
Also they found different objects in the sky and named them nebula. One man pointed the telescope to some these clouds and found most them were moving away from us the further away they were the faster they moved. Soon all kinds of objects were found. Some did not light get through, some gave a beacon like lighthouse, some were so dense that a teaspoon would weigh many tonnes, there wanderers
around the distant fires. We figured out how the stars worked and found some that could kill us if we were closer. We have sent 500 people into space and put a dozen on the moon. We have sent probes to other planets, we launched telescopes into space and found solar systems in development, planets larger than Jupiter and soon planets the size of ours. Even when we make to the other Earths we will still look up to see what is still out there.

Why the anti-electric universe?
The reason is explain how the electric force and the phase of matter known as plasma relates to the other forces and other phases of matter. There are web sites out there claim that scientists are in cult of gravity and do not give the electric universe theory chance. If you do look at the electric universe theory you notice it is not really a theory but a group of hypothesis or guesses that sometimes do not agree with each other so it is not a theory in that respect. Also science needs evidence to support the theories which the electric universe does not. Do not get me wrong electricity and plasma do hold an important rule in the cosmos but alongside the weak, strong and
gravity.
My background is that I tried twice to get a physics degree and failed, but I still have a little knowledge how science and physics works. How this started was about four years ago I started posting about at bautforums.com and soon was introduced to the electric universe. The real argument I got into was with someone claiming the sun had a solid surface made of iron. There have many others discussing these ideas over the Internet so this is going to another drop in the bucket but hopefully a helpful one. I am no export in any of these areas but I will provide links and list of books were applicable and encourage you not to take my word for it and do research of your own. The rate that articles appear will be random because of limited time access the Internet.

Close encounter of the moose kind
As some of you know I work the late shift at a call center. The trip between the call center and my home is about 40 km. Some of the road has guard rails because the drop off can be fairly steep. Well I was going down hill that has the rails on it and I notice some in the other lane. It was dark and light then I hit the brakes. The thing got into my lane the I realized it was a yearling moose, and I just luckily just missed hitting it by just a couple of feet. Then when I try to get a picture then it started running down the road and went into someones driveway and then into the woods.
