Recent studies of comet Tempel 1 (Figure 3) have shown evidence of organic molecules, clay particles as well as liquid water, providing an ideal setting for the operation of the “clay theory” of the origin of life (Cairns-Smith, 1966; Napier et al., 2007).

The Ball-of-Light Particle Model predicts a Pulsar is a ball-of-light that has a very powerful electromagnetic wave sweeping across its surface. The pulsar has no outer envelope of material such as the outer plasma envelope of a normal star.
If the Ball-of-Light Particle Model is correct, then the magnetic field orientation of the top and bottom hemispheres in the above graphic should be curling in opposite directions. If the traditional theory of pulsars is correct, then the magnetic fields in the above graphic should be oriented in the same direction. A recent image of the Egg Nebula from the Hubble Space Telescope is shown below.

Notice how the light is polarized in opposite directions. This matches the Ball-of-Light Particle Model, not traditional theory.

Astronomers to Use Pulsars to Detect Gravitational Waves Created by Super-Massive Black Holes

6a00d8341bf7f753ef0134850fc301970c-320wi Last year, an international team of scientists discovered a promising way to fine-tune pulsars into the best precision time-pieces in the Universe and provide astronomers with a new tool to study the powerful gravitational forces that shaped the universe.

Pulsars--incredibly fast spinning collapsed stars--have been studied in great detail since their discovery in 1967.

Pulsars rank at or near the top of freaky phenomena found in our Universe. In the early 1930s, California Institute of Technology astrophysicist, Fred Zwicky, an immigrant from Bulgaria, focused his attention on a question that had long troubled astronomers: the appearance of random, unexplained points of light.

It occurred to Zwicky that if a star collapsed to the sort of density found in the core of atoms, the result would be an unimaginably compacted core: atoms would be crushed together with their electrons squeezed into the nucleus, forming neutrons and a neutron star, with a core so dense that a single spoonful would weigh 200 billion pounds. But there's more, Zwicky  concluded: with the collapse of the star there would be  huge amounts of leftover energy that would result in a massive explosion,  the biggest in the known universe that we called today supernovas.

Gravitational Waves
At the NASA Goddard Space Flight Center's Laboratory for High Energy Astrophysics, a new research group is devoting their collective effort to understanding and detecting gravitational waves. Scientists are creating computer programs to model gravitational waves that will be detected by a new NASA satellite, called LISA.

General Relativity

In 1916, Albert Einstein published his famous Theory of General Relativity. His theory describes how space-time is affected by mass. We can think of space-time as a fabric that bends or curves when we place an object on it. Keep in mind that the 2-dimensional fabric analogy is just a model we use to represent what is actually 4-dimensional space-time (the normal three dimensions of space, plus a fourth dimension of time).

Imagine pulling a sheet taut and placing a bowling ball in the center of it; you will notice that the ball produces a curve in the sheet. The curve is weak far away from the ball, and steeper near the ball. In fact, the sheet is a bit stretched in that area near the ball, as well. This situation describes the curvature of space-time, and how it is affected by mass. Near a mass, space-time curves more drastically and stretches. Near a very large mass, the 'dent' in space-time is very deep, and the stretches are near the breaking point. This means that since space-time stretches near a mass, not only is space stretched out, but so is time. What do you think would happen if you put something extremely heavy on the sheet? Obviously, you might have a hard time holding the sheet up, but imagine that you had some help from Superman. The heavy object would break through the sheet! In space, this is what we call a black hole. The mass is so large that anything that comes near it (even light) falls through the hole, and is never able to return.

So What is a Gravitational Wave?

Most scientists describe gravitational waves as "ripples in space-time." Just like a boat sailing through the ocean produces waves in the water, moving masses like stars or black holes produce gravitational waves in the fabric of space-time. A more massive moving object will produce more powerful waves, and objects that move very quickly will produce more waves over a certain time period.

Where Do Gravitational Waves Come From?

Gravitational waves are usually produced in an interaction between two or more compact masses. Such interactions include the binary orbit of two black holes, a merge of two galaxies, or two neutron stars orbiting each other. As the black holes, stars, or galaxies orbit each other, they send out waves of "gravitational radiation" that reach the Earth, However, once the waves do get to the Earth, they are extremely weak. This is because gravitational waves, like water waves, decrease in strength as they move away from the source. Even though they are weak, the waves can travel unobstructed within the 'fabric' of space-time. This how they are able to reach the Earth and provide us with information that light cannot give.

How Can We Detect Gravitational Waves?

Since the waves are so weak when they reach us, scientists had to use their imaginations to come up with instruments sensitive enough to detect such slight variations in space-time. Interferometry is the technique astronomers use to detect small stretches in space-time. The technique requires test masses to be set at a large distance from each other. Lasers make continuous measurements of the distance between each of the test masses. The masses are free to move so that when a gravitational wave passes, the distance between the masses will fluctuate. That is, space-time will be stretched. The lasers record this variation in distance, and the scientists know that a wave has passed. The greater the distance between the masses, the more sensitive the lasers are to small fluctuations. There are currently several ground-based detectors in operation or under construction, including LIGO (USA), VIRGO (Italy/France), GEO (Germany/Great Britain), and TAMA (Japan). The space-based observatory LISA is scheduled to launch in 2011.
In order to detect gravitational waves, it is necessary to create a model of what the incoming waveform might look like. Since there are so many sources at a given time, scientists must create computer models of gravitational waves so they know what to look for in what seems like a huge mess of data. Dr. Joan Centrella, a theoretical astrophysicist at NASA's Goddard Space Flight Center, leads a team of scientists who create these models. Currently, the group is working on computer models of massive black hole coalescences that occur when the black holes at the centers of two colliding galaxies spiral into each other. "Once we have the models for this system, we can just substitute different masses for the black holes. That way, several models can be made from one program," says Dr. Centrella.

What Will We Learn From the Detectors?

Gravitational waves will help physicists and astronomers to understand some of the most fundamental laws of physics. They will also tell us about the dynamics of large-scale events in the Universe like the death of stars, and the birth of black holes. With LISA, scientists will be able to probe through space and time, to observe the Universe just a fraction of a second after the Big Bang. Using this information, we may be able to learn more about how the Universe began and evolved as well as what might be in store for the future.
