Gamma Ray Detection

A important point here is that there should be coincidental features in gamma ray detection, that should align with LIGO detectors?

Why are two installations necessary?


At least two detectors located at widely separated sites are essential for the unequivocal detection of gravitational waves. Local phenomena such as micro-earthquakes, acoustic noise, and laser fluctuations can cause a disturbance at one site, simulating a gravitational wave event, but such disturbances are unlikely to happen simultaneously at widely separated sites.


Lubos said::
The LIGO collaboration informed that the second science run did not detect any gravitational waves. The results follow from 10-day-long observations in early 2003 (two more science runs have been made ever since)


A current blackhole has been detected and so should LIGO detect it. So how long should we wait if findings are only now being conisdered from 2003 run?

Scientists have detected a flash of light from across the Galaxy so powerful that it bounced off the Moon and lit up the Earth's upper atmosphere. The flash was brighter than anything ever detected from beyond our Solar System and lasted over a tenth of a second. NASA and European satellites and many radio telescopes detected the flash and its aftermath on December 27, 2004. Two science teams report about this event at a special press event today at NASA headquarters.


Journey to a Black Hole

A direct image of gravity at its extreme will be of fundamental importance to Physics. Yet imaging a black hole requires a million times improvement over Chandra. That's a big step. Over the next 20 years, the Cosmic Journeys missions will take us closer and closer to a black hole though the power of resolution. Each successive mission will further us in our journey by 10- or 100-fold increases in resolution, step by step as we approach our goal of zooming in a million times closer. And each stop along the way will bring us new understandings of the nature of matter and energy.

GLAST is a gamma-ray observatory mission that will observe jets of particles that shoot away in opposite regions from a supermassive black hole at near the speed of light. We do not fully understand how a black hole, which is known for pulling matter in, can generate high-speed jets that stretch out for billions of miles. Galaxies that harbor black holes with a jet aimed in our direction are called blazars, as opposed to quasars, which have their jets aimed in other directions. GLAST, up to 50 times more sensitive than previous gamma-ray observatories, will stare down the barrel of these jets to unlock the mechanism of how the enigmatic jets form. The Constellation-X mission will probe the inner disk of matter swirling into a black hole, using spectroscopy to journey 1,000 times closer to a black hole than any other mission before it. With such resolution, Constellation-X will be able to measure the mass and spin of black holes, two key properties. This X-ray mission will also map the distortions of space-time predicted by Einstein. Constellation-X draws its superior resolution by pooling the resources of four X-ray satellites orbiting in unison into one massive X-ray telescope. The ARISE mission will produce radio-wave images from the base of supermassive black hole jets with resolution 100,000 times sharper than Hubble. Such unprecedented resolution can reveal how black holes are fed and how jets are created. ARISE will attain this resolution through interferometry. This technique is used today with land-based radio telescopes. Smaller radio telescopes spread out on land -- perhaps one mile apart -- can work together to generate a single, huge radio telescope with the collecting power of a one-mile radio dish. ARISE will utilize one large radio telescope in space with many other radio telescopes on Earth, bringing what is now a land-based technology to new heights

New NASA Satellite to Study Black Hole Birth and Gamma Ray Bursts


The Swift observatory comprises three telescopes, which work in tandem to provide rapid identification and multi- wavelength follow-up of GRBs and their afterglows. Within 20 to 75 seconds of a detected GRB, the observatory will rotate autonomously, so the onboard X-ray and optical telescopes can view the burst. The afterglows will be monitored over their durations, and the data will be rapidly released to the public.

    Clementine Project Information


    Clementine was a joint project between the Strategic Defense Initiative Organization and NASA. The objective of the mission was to test sensors and spacecraft components under extended exposure to the space environment and to make scientific observations of the Moon and the near-Earth asteroid 1620 Geographos. The observations included imaging at various wavelengths including ultraviolet and infrared, laser ranging altimetry, and charged particle measurements. These observations were originally for the purposes of assessing the surface mineralogy of the Moon and Geographos, obtaining lunar altimetry from 60N to 60S latitude, and determining the size, shape, rotational characteristics, surface properties, and cratering statistics of Geographos.


    Look at Clementine and the moon. The way they measured gravity there( the satellite lag)? The geological perspective gained from mapping the moon? The frames of reference are thus quite dynamical when you use this perspective to gain new insights developed from the work of Einstein.

    Green Cheese?

    The Clementine gravity experiment used measurements of perturbations in the motion of the spacecraft to infer the lunar gravity field

    The complexity of measuring events in the cosmos, was to see information contained in what exists around us now. Using various locations they are trying to ascertain simultaneous correspondances in the signals from these cosmological locations, as a well as use the distance between these earth based locations.

    Gravity for instance, varies with Time

    Gravity is "flavor blind," so when a microscopic blackhole evaporates it produces all the Standard Model particles with equal probability. Once one accounts for spin and color, it turns out that particles produced when a blackhole decays are about 72 percent quarks and Gluons, 18 percent leptons, and the rest are bosons. Such a distinctive shower of particles would be hard to miss. So there is the possibility that the Pierre Auger Observatory will detect blackholes.
    Page 262, Out of this World, by Stephen Webb

    In a complex world of uncertainty this is hard to do, so you look for the ways to see how the cosmic rays create the situations for particle production. So you look for the origins of any number system that began, and how it was used to explain the natural world.

    An Excursion into the Dimensions of Numbered Systems

    An example here would be using Pascal's triangle. If you "blanket" using resonances pertaining to all number deveopements, then we might understand the harmonies created? Topological movements?

    In a euclidean world, the developing geometries will lead somewhere, but how did you every arrive from topological states to euclidean frames of reference? You had to understand the physics process.

    So from space to earth, the earth, a final physical state. But you understand that it existed in other states as well? That's where you learn to use the physics.

    Time-Variable Gravity Measurements



    Mean Gravity Field


    The Mean Gravity Field lets us work from this mass understanding and provides for, flunctuations in that Gravity field hence the understanding of Time Variable Gravity Field


    On planet Earth, we tend to think of the gravitational effect as being the same no matter where we are on the planet. We certainly don't see variations anywhere near as dramatic as those between the Earth and the Moon. But the truth is, the Earth's topography is highly variable with mountains, valleys, plains, and deep ocean trenches. As a consequence of this variable topography, the density of Earth's surface varies. These fluctuations in density cause slight variations in the gravity field, which, remarkably, GRACE can detect from space.


    I wanted to put this into perspective, since we can extend our vision of the gravity field, and how we would look at mass distribution. Using this method, we calibrate, understanding current topological features of hills and valleys that serve to remind us, of the mass distribtuion that has gone on in the formation of our planet Earth.

    Since passing over these locations calculations recognize these density valuation of mass regions. This allows us to understand the current gravity standard placed on that location.

    Time-Variable Gravity Measurements from the GRACE Satellite


    NASA, in partnership with the German Space Agency DLR, launched the dedicated gravity satellite GRACE (the Gravity Recovery and Climate Experiment) in March, 2002. This five year mission will map out the Earth's gravity field to unprecedented accuracy at monthly intervals. The temporal variations in gravity inferred from these data will allow people to study a wide range of processes, cutting across a variety of Earth science disciplines, that involve redistribution of mass within the Earth and at or near its surface. It will be possible, for example, to produce monthly estimates of changes in continental water storage anywhere in the world, averaged over scales of a few hundred km and greater, to accuracies of better than 1 cm water thickness.


    I have referrred to the hill and valley perspectives that have arisen in relation to how we see the landscape(earth's). If this feature was not comprehended in some model application, would it not have served to settle minds who see no valuation in such landscape perspectives, as a basis to a much better understanding of the nature of the universe, and the reality around us?

    Where has the extra energy gone? For some scientists this question highlights something interesting about what extra dimensions might have implied? You gauge the gravitational fields and learn to see time variability as a feature not just of mass consideration, but of energy determinations as well. It's only fitting?:)


    The image above shows the many processes of the Earth’s hydrologic cycle that contribute to total changes in water storage


    So setting up a comprehensive understanding of these differences, the mean gravitational field and Time Variable gravity field we see now some relationship to things finer in its constitution, and the relationship to Climate.


    The Landscape?


    What value might be assigned to this understanding, that we look at how such emissions and its effect on the information gathered. Would we see the effect of civilizations and the way this has effecedt those particular geographical regions.

    Have we thus found a legitimate model, that current debates on the Kyoto protocals might serve to get everyone on base for determinations. Will this effectvely change the dialogue currently going on in our assessments, of the needed reduction of CO2 emissions?

    Seeing Beyond the Mass and Density?


    Fig.1: Generally Grouping Order increases the density of objects within a frame of reference, resulting in a more pronounced single object.


    To see beyond what we have taken for granted it is important that you understand how we got to the way we are. Above the diagram helps you too orientate these views in accordance with established sciences.

    A lot of thought have been going through my mind about what is currently being manifested all around us in terms of all the wavelengths that we are inundating to our environment. Television, cell phones, electric grid lines and all the sorts and I am wondering if, we have basically interrupted, the process in nature that is natural, and supplemented it with human kinds fabrications?

    Lets just focus on matter distinctions then for now and how such inundations above might have found some comparative views in what nature decided to do for us. In how it density variations would have aligned themselves over the planet during it's formation?



    The distribution of mass over the Earth is non-uniform. GRACE will determine this uneven mass distribution by measuring changes in Earth’s gravity field.The term mass refers to the amount of a substance in a given space, and is directly correlated to the density of that substance. For example, a container filled with a more dense material, like granite, has more mass than that same container filled with water. Because mass and density are directly related, there is also a direct relationship between density and gravity. An increase in density results in an increase in mass, and an increase in mass results in an increase in the gravitational force exerted by an object. Density fluctuations on the surface of the Earth and in the underlying mantle are thus reflected invariations in the gravity field.As the twin GRACE satellites orbit the Earth together, these gravity field variations cause infinitesimal changes in the distance between the two. These changes will be measured with unprecedented accuracy by the instruments aboard GRACE leading to a more precise rendering of the gravitational field than has ever been possible to date.


    In looking up the word "in variation" you won't have much luck, but in context of the sentence, it forces you to look back towards the center, from the surface. I think this is right?

    Quite early in the developing aspects of my research, I was drawn to statement of the above in regards to mass/density, which could have represented to me the vibration inherent, as sound, in how we would determine this mass? Was it unreasonable to look at what nature had bestowed upon us and wonder, that if such sounding processes within the mantle would have allowed us to determine where the structural integrity of the planet would have sufficed in taking accountability of proper building perspectives.

    Clementine color ratio composite image of Aristarchus Crater on the Moon. This 42 km diameter crater is located on the corner of the Aristarchus plateau, at 24 N, 47 W. Ejecta from the plateau is visible as the blue material at the upper left (northwest), while material excavated from the Oceanus Procellarum area is the reddish color to the lower right (southeast). The colors in this image can be used to ascertain compositional properties of the materials making up the deep strata of these two regions. (Clementine, USGS slide 11)

    Preparing the mind for information about gravitational fields were extremely important to me because if gravity discernment in terms of the planets density fluctuations were evident from mass/ density consideration, then how would we be certain that such information emitted from events, which shake the space time fabric would not have sounded for us a response distinctive about it's particle identification. Was there some layering aspect designed within gravitational consideration that would have said the density of the material would have been found, a center first must be of iron?

    As one of the fields which obey the general inverse square law, the gravity field can be put in the form shown above, showing that the acceleration of gravity, g, is an expression of the intensity of the gravity field.

    So in the ideal centricity of elements such gravitational consideration would have aligned the material in a appropriate expression from the densest of matter distinctions to the very light, would have made it seem, that such resonances based in sound would say, that because it is dense here at the iron core, the sound value would be very distinctive from the vibrational freedom at the surface?

    Density measure(comparative to other things) of sound, would be nice. Which leads me to the ideals of Webber and his aluminum bars.

    Radar echos from Titan's surface



    This recording was produced by converting into audible sounds some of the radar echoes received by Huygens during the last few kilometres of its descent onto Titan. As the probe approaches the ground, both the pitch and intensity increase. Scientists will use intensity of the echoes to speculate about the nature of the surface.
