Gravitational Wave Detectors are Best Described as "Sounds."


Weber developed an experiment using a large suspended bar of aluminum, with a high resonant Q at a frequency of about 1 kH; the oscillation of the bar after it had been excited could be measured by a series of piezoelectric crystals mounted on it. The output of the system was put on a chart recorder like those used to record earthquakes. Weber studied the excursions of the pen to look for the occasional tone of a gravitational wave passing through the bar...


You have to go back to what was initiated to help put perspective on what the analogies do for us today?

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


So you have it firmly set in mind, where gravitational waves are set in the whole scheme of things? What values would you practise if Bulk perspectives were to allow you to see gravitational waves in it's two extremes?




Gravitational waves are ripples in the fabric of space and time produced by cosmic violence, such as the the universe's big-bang creation and collisions of black holes. These waves carry information about the "dark side" of the universe that cannot be learned in any other way. The high-frequency gravitational-wave window onto the universe will be opened soon by LIGO (NSF's earth-based Laser Interferometer Gravitational Wave Observatory, which is now in operation and searching for waves). A lower-frequency window will be opened in ~2012 by LISA (the NASA/ESA Laser Interferometer Space Antenna). This lecture will describe LIGO, LISA, and what they may teach us about the universe and about warped spacetime


Where are gravitational waves very strong, and where they are very weak?

Well, do you think such "detachments are practised" when you look at the event? The "sound" is emitted at the "very beginning" and the sound is, "specific?"


We can't actually hear gravitational waves, even with the most sophisticated equipment, because the sounds they make are the wrong frequency for our ears to hear. This is similar in principle to the frequency of dog whistles that canines can hear, but are too high for humans. The sounds of gravitional waves are probably too low for us to actually hear. However, the signals that scientists hope to measure with LISA and other gravitational wave detectors are best described as "sounds." If we could hear them, here are some of the possible sounds of a gravitational wave generated by the movement of a small body inspiralling into a black hole.


When such "analogies" are held in mind, you learn to understand the history of gravitational wave research based on "experimental processes" that were adopted by some to push forward our perspective on the very nature and description "such sounds emitted" may refer too?



So I began to see the whole picture in relation to how we would assess the movement towards "reconstruction of information" that leads from recreating the event from statistical information gathered from our "computerized measures" extended out there, to views of the early universe?

How shall you construct information of "an event" that is unfolding? So scientifically indeed, "experimentalism" has to be taken to new heights with which to construct such views of the early universe.

If you understood the nature of curvature, and the dynamical nature you have imbued quantum views then why would you not accept the views that the quantum nature will impart to you the nature of gravity?

So by preparing oneself as to the ways in which the bulk is perceived, you now have this means with which to judge the events in the cosmos, not just as a after effect of what happened at the time but of the story unfolding from that time?

This doesn't excuse all that is left in the bulk for perspective, because you need to remember the very nature of all constructs have been left for you to look at, as you "rebuild these images" of what happened so long ago. Actually exist in the bulk right now as information?

So you understand Bekenstein Bound do you?

Okay, keep going then with these views as they unfold, and as I have demonstrated them as I "portrait the universe" in the way that I see. It is difficult to get across as a painter, the language barrier, if it does not a have a mutual agreement to interpretation, then it has to be done on a experimental basis.

We all know that, Peter Woit.


The analogy with condensed matter physics was thus introduced to see if the asymptotic properties of the Hawking phonons emitted by an acoustic black hole, namely stationarity and thermality, are sensitive to the high frequency physics which stems from the granular character of matter and which is governed by a non-linear dispersion relation. In 1995 Unruh showed that they are not sensitive in this respect, in spite of the fact that phonon propagation near the (acoustic) horizon drastically differs from that of photons. In 2000 the same analogy was used to establish the robustness of the spectrum of primordial density fluctuations in inflationary models. This analogy is currently stimulating research for experimenting Hawking radiation. Finally it could also be a useful guide for going beyond the semi-classical description of black hole evaporation.

Cosmological and Microstate Blackholes



Perspectives On Nature's Greatest Puzzles

Nima Arkani-Hamed
:
First rule of progress in science-better to follow your nose, then twiddle your thumbs



My perspectives are elementary generalizations from the views of those at the forefront of theoretcical research into comprehenson of the nature of this cosmo and the ideas of it's cyclical nature. Where else shal we consider this rebirth of sorts but to have been taken to the origins and how we percieve this same universe?

From the general public perspective concepts, which are developing will never make sense, if they did not understand the work that brought these two perspectives together and created this trend to the cosmological pallette for fun, with the theoretical approaches seen in high energy considerations?

Once these views of the cosmological design were contemplated, they revealled a deeper intricacy into the geometry/topological considerations. It was not to far a leap to considered the early universe foundations in the gravitational collapse of those same blackholes, would lead us to the ideas in high energy considerations.


Has the Track Record Been Poven?

Nima Arkani-Hamed:
Our Mantra:
LHC + L.C. will reveal natural theory of weak scale



Once it was understood that such balckhole creation could be idealic produced in the in high energy considerations, the expansive technique to developemental policies quickly reocgnized the diversity? With how the new views would form in minds which had been enaged in string theory. To understand well this covering, that had been placed over all the perspective leading through the standard model comprehension mode. They had discovered the nature of this cyclical universe already?:)

Should this be transcended into allotment of financial gain and to push perspective into the most approrpiate directions? Was it was safe and sound enough in the work that had been moved into the idealization of those same microstate blackholes, then the choice given John Ellis and others would have been far reaching in what direction such courses of event would lead too, into the future.

Having recognized that these trends would now force the move from theoretical design to one of experiementalist having developing proofs , John moves us forward here in the developement phase of cosmological interactions taking place in the field of experience of our earth and it's relation with the sun.

LIGO Translation

But lets not forget the work LIGO has done in transforming our views of the early history. Webber, John Wheeler and Kip Thorne and others, took it upon themselves to orientate the view not once, but many times to see where such progression has lead to the developement of LIGO operations and Detection.

This forced the current trends in string research to produce students that would move this subject into new directions? Now geared to questions of what that gravity might have surmised in its expression and developement. Hence the title of this thread.

Great Circles



You would think with this uncertainty, that I had answered my own question about what Peter Woit has done, in terms of offering some substantiative understanding for rejection of string theory. But it doesn't.

Sometimes we rely on the roads taken by Webber, Wheeler and Kip, and those who understood well the consequence of gravitational considerations, to further enhance these specualtive journies and to better explore the bulk that might have varying attributes?


The theory of relativity predicts that, as it orbits the Sun, Mercury does not exactly retrace the same path each time, but rather swings around over time. We say therefore that the perihelion -- the point on its orbit when Mercury is closest to the Sun -- advances
.


What am I saying here? You mean, that in the primordial understanding there are extensions of what could be thought of in terms of strength and weakness, in gravitational terms? I would most certainly like to see the light shining in these circumstances.:)But like anything of course, we like to LIGOlize these terms for further consideration. Don't we?


Let us see how these great physicists used harmonic oscillators to establish beachheads to new physics.

How many Possibilities Exist in the Now?




What is leading our perspective in regard to what has been left in the bulk for us to consider? It is this, that roams freely and leaves for us a detailed impression about information from another time and place.

Quickly one realizes that to trace a event that happen back in time, this information had to travel? That it could penetrate all existence and not be held to it, leads one to see the earth as a place where the information will resonate for us in our conceived views of measure in those Bars, and LIGO?



What should human thought do, but limit the realization that such dimensional perspective does not resonate through all things? That math, of higher dimensional realization must also follow a geometrical pathway that I have commented on before in Klein's ordering of geometries?

How could we move this idealization to topology, as some point of Hinton's circle touching the brane and leading to some idealization of a positive view of Riemann's sphere and lead too boson production, as a graviton descriptor of those same gravitational waves?

I never thought such concepts could have ever come to some fruition, that I would have argued against the established views of one who would engage superstringtheory(Peter Woit?) and having become acquainted, would reject any hint of this flavor, as a possible definition of the reality that exists around us, and through us?





Joseph Weber 1919 - 2000
In the late 1950s, Weber became intrigued by the relationship between gravitational theory and laboratory experiments. His book, General Relativity and Gravitational Radiation, was published in 1961, and his paper describing how to build a gravitational wave detector first appeared in 1969. Weber's first detector consisted of a freely suspended aluminum cylinder weighing a few tonnes. In the late 1960s and early 1970s, Weber announced that he had recorded simultaneous oscillations in detectors 1000 km apart, waves he believed originated from an astrophysical event. Many physicists were skeptical about the results, but these early experiments initiated research into gravitational waves that is still ongoing. Current gravitational wave experiments, such as the Laser Interferometer Gravitational Wave Observatory (LIGO) and Laser Interferometer Space Antenna (LISA), are descendants of Weber's original work.


Maybe, I should be careful here, as to the realization of gravitatinal waves having not been proven to exist? It has become well known, what GR stands for?:)



Gravitational Radiation

Gravitational waves have a polarization pattern that causes objects to expand in one direction, while contracting in the perpendicular direction. That is, they have spin two. This is because gravity waves are fluctuations in the tensorial metric of space-time.

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.

Quantum Harmonic Oscillators




If the basis of this thinking has not emerged out of GR then what value could we have assigned zero point vibration? If the scalable features of GR could not have followed some geometrical thinking, then the world that we move too, in non-euclidean views, could have never revealled hyperdimensional thinking. Which needs a quantum mechanical thinking to emerge as well?

Geons, Blackholes & Quantum Foam, by John Archibald Wheeler, with Kenneth Ford, page 236, para 2.
"
This hypothetical entity, a gravitating body made up entirely of electromagnetic fields. I call geon(g for the gravity, e for electromagnetism," and on as the word root for"particle"). There is no evidence for geons in nature and later was able to show that they are unstable-they would quickly self-destruct if they were ever to form. Nevertheless it is tempting to think that nature has a way of exercising all the possibilties open to it. Perhaps geons had a transitory exitance early in history of the universe. Perhaps(as some students and I speculate much more recently), they provide an intermediate stage in the creation of the balckholes

If such thinking of the spacetime would have been moved from macroscopic thinking, how would we have ascertained the continued developement of GR from this as an microscopic view?



Without some way in which to look at the developing nature of GR, how would we not have not of considered the nature of these gravitational events in the cosmo? If we coud not scale the nature of the measure, between two points, what value would there ever be in considering the strength of the gravitational fields?

Gravitational waves can be viewed as ripples of the space-time. They occur in two fundamental states of polarization, usually known as 'cross' and 'plus'. The effect on matter of the passage of gravitational radiation is a squeezing and stretching, depending on the phase of the wave. For instance the effect on a ring of test masses is shown in fig. 1, in the reference frame that is in free fall with the center of mass. The upper raw refers to the plus polarization while the second to the cross polarization; the ring is deformed by the wave and the effect is shown at different phases

As we look back in time, here it is easy to see having understood this developement of gravitational wave detection that the principals underlying the developing thoughts came from Webber's expansive contractive, features of all things? It would manifest through all things and Kip Thorne deducing this understanding, was lead to consider LIGO as a important fucntion of discerningthese grviaational waves. INstead of Webber's way of thinking he developed another way in which to percieve this energy being deciminated in the bulk of our imaginations.
