The Sound of Two Black Holes Colliding


Audio Credit: Caltech/MIT/LIGO Lab

 As the black holes spiral closer and closer in together, the frequency of the gravitational waves increases. Scientists call these sounds "chirps," because some events that generate gravitation waves would sound like a bird's chirp. See: The Sound of Two Black Holes Colliding

This is an Audio Animation above.

The upcoming network of Earth-based detectors, comprising Advanced Virgo, KAGRA in Japan, and possibly a third LIGO detector in India, will help scientists determine the locations of sources in the sky. This would tell us where to aim “traditional” telescopes that collect electromagnetic radiation or neutrinos. Combining observational tools in this way would be the basis for a new research field, sometimes referred to as “multimessenger astronomy” [7]. Soon we will also collect the first results from LISA Pathfinder, a spacecraft experiment serving as a testbed for eLISA, a space-based interferometer. eLISA will enable us to peer deeper into the cosmos than ground-based detectors, allowing studies of the formation of more massive black holes and investigations of the strong-field behavior of gravity at cosmological distances [8].See: Viewpoint: The First Sounds of Merging Black Holes

The Map of B Mode Imprints


Figure 3: Left: BICEP2 apodized E-mode and B-mode maps filtered to 50 < ℓ < 120. Right: The equivalent maps for the first of the lensed-ΛCDM+noise simulations. The color scale displays the E-mode scalar and B-mode pseudoscalar patterns while the lines display the equivalent magnitude and orientation of the linear polarization. Note that excess B-mode is detected over lensing+noise with high signal-to-noise ratio in the map (s/n > 2 per map mode at ℓ ≈ 70). (Also note that the E-mode and B-mode maps use different color/length scales.)

 You know the distinctions on how one might see information as purported to exist as gravitational waves  of course held my perspective. Like others,  is this a way in which BICEP has illustrated something of the every nature of space-time, as to my thoughts then, when it really was only about seeing a footprint in the WMAP.


Gravitational waves open up a new window on the universe that will allow us to probe events for which no electromagnetic signature exists. In the next few years, the ground-based interferometers GEO-600, LIGO, VIRGO and TAMA should be able to detect the high-frequency gravitational waves produced by extreme astrophysical objects, providing the first direct detection of these disturbances in space–time. With its much longer arm lengths, the space-based interferometer LISA will, if launched, be able to detect lower-frequency gravitational waves, possibly those generated by phase transitions in the early universe. At even lower frequencies, other experiments will look for tiny signatures of gravitational waves in the cosmic microwave background. Source: NASA.

So it is a footprint then and I might show some of those maps and ask what do these footprints show in the early universe as to say, that given the inflationary timeline what can be garnered about looking back so far as to suggest 13.8 billion years and have such an imprint hold relevance, and equal the very nature of space-time itself.

The nature of the question for me is a "sensor mode developmental model" that chooses to exemplify gravitational waves over another and I had to make this clear for myself. So you can see where this has lead me. To where I want to further understand. If you choose not to show a comment then I guess that is where I lose.

 
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...

See:Weber Bars Ring True?

The analogy rests with how the nature of gravitational waves had been sounded so as to show a connection to the WMAP as a footprint. So you have this 2 dimensional map surface as to exemplary how gravitational waves may appear on it, yet,  the visual extent of that correlation is representative to me of a defined configuration space. You need your physics in order to establish any correlation to the timeline of the inflationary model and to see that such a map reveals efforts to penetrate the Planck era. To suggest quantum gravity.

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.

So indeed to have such a map is very telling to me not just of the imprint but also of the sensory mode we had chosen to illustrate that map of the B mode representation as a valid model description of that early universe.

Weber Bars Ring True?



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.


How would you map this above?

WMAP image of the Cosmic Microwave Background Radiation


Here's the thing for those blog followers who are interested in the application of sound as a visual representation of an external world of senses.



 In this example I’m going to map speed to the pitch of the note, length/postion to the duration of the note and number of turns/legs/puffs to the loudness of the note.See: How to make sound out of anything.

I have my reasons for looking at the trail that began with Gravitational wave research and development. If we are accustom to seeing and concreting all that reality has for us,  can a question be raised in mind with how one has been shocked by an anomaly?

I am not asking for anyone  to abandon their views on the science of,  just respect that while not following the rules of  science here as to my motivational underpinnings, I have asked if science can see gravity in ways that have not be thought of before.  This is not to counter anything that has been done before.

The historic approach to Gravitational Research was important as well,  to trace it back to it's beginning.

Can we use such measures to exemplify an understanding of the world we live according  to a qualitative approach? This has occupied my thoughts back to when I first blogged about JosephWeber in 2005. Here is a 2000 article linked.
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 aluminium 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 sceptical 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. See:Joseph Weber 1919 - 2000

Space, we all know what it looks like. We've been surrounded by images of space our whole lives, from the speculative images of science fiction to the inspirational visions of artists to the increasingly beautiful pictures made possible by complex technologies. But whilst we have an overwhelmingly vivid visual understanding of space, we have no sense of what space sounds like.

Weber Bars

The following detectors participate into the IGEC. Click on a name to connect to the experiment web site.
In the picture below the detectors locations on earth are represented. It happens that there is a great circle passing near each site (red line on the picture below) This allows for parallel orientation of the bars.
See: How many Possibilities Exist in the Now? 


Resonant Gravitational Wave Detectors

I do need to clarify my mistake on the spelling of Joseph Weber and the double bb I had given his last name.

Weber Bar
A simple device to detect the expected wave motion is called a Weber bar – a large, solid bar of metal isolated from outside vibrations. This type of instrument was the first type of gravitational-wave detector. Strains in space due to an incident gravitational wave excite the bar's resonant frequency and could thus be amplified to detectable levels. Conceivably, a nearby supernova might be strong enough to be seen without resonant amplification. Modern forms of the Weber bar are still operated, cryogenically cooled, with superconducting quantum interference devices to detect vibration (see for example, ALLEGRO). Weber bars are not sensitive enough to detect anything but extremely powerful gravitational waves.[1]


The MiniGRAIL detector is a cryogenic 68 cm diameter spherical gravitational wave antenna made of CuAl(6%) alloy with a mass of 1400 Kg, a resonance frequency of 2.9 kHz and a bandwidth around 230 Hz, possibly higher. The quantum-limited strain sensitivity dL/L would be ~4x10-21.

MiniGRAIL is a spherical gravitational-wave antenna using this principle. It is based at Leiden University, consisting of an exactingly machined 1150 kg sphere cryogenically cooled to 20 mK.[2] The spherical configuration allows for equal sensitivity in all directions, and is somewhat experimentally simpler than larger linear devices requiring high vacuum. Events are detected by measuring deformation of the detector sphere. MiniGRAIL is highly sensitive in the 2–4 kHz range, suitable for detecting gravitational waves from rotating neutron star instabilities or small black hole mergers.[3]

AURIGA is an ultracryogenic resonant bar gravitational wave detector based at INFN in Italy. It is based on a cylindrical bar detector. The AURIGA and LIGO teams have collaborated in joint observations.[4]

Observational Gravitational-Wave Astronomy.


Figure 1: Gravitational wave strain and strain sensitivity for a 5 year observation with PTAs.
The red dashed line is the approximate strain sensitivity for current PTAs (11), and the green
dashed line shows the previous estimate for the stochastic signal strength that is currently in
standard use for PTA analyses (13, 14). The dark blue solid line corresponds to our mean
estimate for the stochastic signal strength, with the blue shaded region bound by thin solid
blue lines showing our 95% confidence interval for this estimate, based on the observational
uncertainties of our model parameters. The light blue (△ACD) and cyan (△ABE) shaded
regions show the area corresponding to the square root of the 2 integrand, to be integrated over
logarithmic frequency intervals as in Eq. (3), for our expected SNR of 8, and the SNR of 2
expected from previous estimates (13, 14), respectively. See: The Imminent Detection Of Gravitational Waves From Massive Black-Hole Binaries With Pulsar Timing Arrays





As mentioned in article by Technology Review the idea of previous information as to supplying data would have to be identified in future experiments as confirmations. In this instance information gained from Taylor and Hulse  in terms of binary star rotations closeness.

New Synesthete Character on Heroes

For example, in 1704 Sir Isaac Newton struggled to devise mathematical formulas to equate the vibrational frequency of sound waves with a corresponding wavelength of light. He failed to find his hoped-for translation algorithm, but the idea of correspondence took root, and the first practical application of it appears to be the clavecin oculaire, an instrument that played sound and light simultaneously. It was invented in 1725. Charles Darwin’s grandfather, Erasmus, achieved the same effect with a harpsichord and lanterns in 1790, although many others were built in the intervening years, on the same principle, where by a keyboard controlled mechanical shutters from behind which colored lights shine. By 1810 even Goethe was expounding correspondences between color and other senses in his book, Theory of Color. Pg 53, The Man Who Tasted Shapes, by Richard E. Cytowic, M.D.

I had been searching for the latest TV Show on Heroes.

I finally came across somebody who pretty well sees it the way Synesthesis  does?  A fictional TV show cut forYoutube which provided for reference below which was what I was looking for.


Now the followers of this blog must know by now, that I see the "Colour of Gravity" as a link between what can conceptually transpire when the photon is travelling through, or "showing itself" in a gravitational field.

Now, what is right scientifically on this, that what we can say of theoretics which has combined electromagnetism with gravity, is to reveal "a colourful gravitational history" in this way? It brought to mind a dream I had of Einstein stirring a glass container of juice with ice in it. In my cognisance of how sound would reveal and be indicative of gravity speaking, I look to see what Einstein meant by display.

This was triggered I believe by  Joseph Weber's research into the aluminum bars detectors for gravitational wave detection.

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...

Some might not understand the history to which I had devoted to building and understanding the emotive qualities combined with the intellectual. Which lead to seeing dynamical movement between the inner and outer world with respect to the state of mind at any given time. There have always been attempts on my part to describe this motion, not just on the psychological level, but on what also transpires emotively while the emotive state is being expressed.

I cannot say I am a Synesthesis by the 61 definitions given by Sean Day. So in the truest sense, I am not by that definition one. But conceptually linking and intertwining sound and colour with the physiological and the psychological, it was important by that definition be given, what colourful state the mind can be in.

Albert Einstein's perception of time and beauty seemed relevant to me about the quality given in measure, but by this perspective I am sure that is not what Einstein wanted to give meaning too, while thinking of the curvature of space and time.

This then is based on a perspective I have formed around gravity. What attach itself to all of us, whether we see the colours or not by consequence. This is an evolutionary form in my mind of what the soul can gain and loose by recognizing the colourful state of mind at any given time, and how it harbours colour in the truest sense as an expression of that being.

To be left with "no physical form" a mode of being becomes a retention of the abstract thinking mind, sets a tone in my mind for what is to come home to roost.

That we exist then mentally in that very realm, means to learn to recognize the pain and the "duration of time" we associated with those given memories. Upon reflection, we learn something then about the way we relate to the world and people around us which allows us to project "forward future consequences" intellectually bound by creative advances in language construction advancements of "creating in the mental world."

IN the most purest sense then, all combined is the birthing to segregation of sensory abilities according to "cabinets of perspective" that are arranged according to the principals of how we will interact in this community. This by arrangement, on entering materiality.

Gravity Wave Spectrum

PURPOSE: To show the two-dimensional standing waves on the surface of a square or circular plate.


Early perception of sound as analogy to the ideas of the WMAP background were forming in my mind when Wayne HU was demonstrating the image of polarizations in B mode. To me its as if one puts on a pair of glasses and based on an assumption of the gravitational waves, then one tends to see "all of it" in this Lagrangian way.



With the discovery of sound waves in the CMB, we have entered a new era of precision cosmology in which we can begin to talk with certainty about the origin of structure and the content of matter and energy in the universe.Polarization


This was the basis of how I was seeing the progression of Webber's experiments in using the aluminum bars in gravitational wave detection. It was also more then this that I came to the conclusion I did.

Sounding out the Big BangJun 1, 2007 by Craig J Hogan is in the departments of physics and astronomy at the University of Washington, Seattle, US.

Our view of the universe is about to change forever. Since science began, all our knowledge of what lies above, below and around us has come from long-familiar forms of energy: light, produced by distant astrophysical objects; and matter, in the form of particles such as cosmic rays. But we are now in a position to study the universe using an entirely different form of energy that until now has never been directly detected – gravitational waves.





Gravitational waves open up a new window on the universe that will allow us to probe events for which no electromagnetic signature exists. In the next few years, the ground-based interferometers GEO-600, LIGO, VIRGO and TAMA should be able to detect the high-frequency gravitational waves produced by extreme astrophysical objects, providing the first direct detection of these disturbances in space–time. With its much longer arm lengths, the space-based interferometer LISA will, if launched, be able to detect lower-frequency gravitational waves, possibly those generated by phase transitions in the early universe. At even lower frequencies, other experiments will look for tiny signatures of gravitational waves in the cosmic microwave background. Source: NASA.


The flow of energy in a cosmic phase transition is similar to that in a waterfall, with turbulence in the cosmic fluid generating a gravitational-wave background today.

Sound and fluidized interpretation seemed very close to me of the way in which such analogy would help us to look at the universe and the spaces in between cosmological locations, as if, in a three body problem relation.

The Origin of the Universe as Revealed Through the Polarization of the Cosmic Microwave Background submitted by Scott Dodelson Sun, 22 Feb 2009 14:27:37 GMT

Modern cosmology has sharpened questions posed for millennia about the origin of our cosmic habitat. The age-old questions have been transformed into two pressing issues primed for attack in the coming decade: How did the Universe begin? and What physical laws govern the Universe at the highest energies? The clearest window onto these questions is the pattern of polarization in the Cosmic Microwave Background (CMB), which is uniquely sensitive to primordial gravity waves. A detection of the special pattern produced by gravity waves would be not only an unprecedented discovery, but also a direct probe of physics at the earliest observable instants of our Universe. Experiments which map CMB polarization over the coming decade will lead us on our first steps towards answering these age-old questions.

    Loosing Sight of Discrete Geometry

    Discrete mathematics, also called finite mathematics or decision mathematics, is the study of mathematical structures that are fundamentally discrete in the sense of not supporting or requiring the notion of continuity. Objects studied in finite mathematics are largely countable sets such as integers, finite graphs, and formal languages.

    Discrete mathematics has become popular in recent decades because of its applications to computer science. Concepts and notations from discrete mathematics are useful to study or describe objects or problems in computer algorithms and programming languages. In some mathematics curricula, finite mathematics courses cover discrete mathematical concepts for business, while discrete mathematics courses emphasize concepts for computer science majors.


    For me this becomes the question that is highlighted in bold as to such a thing as discrete mathematics being suited to the nature of the Quark Gluon Plasma that we would say indeed that "all the discreteness is lost" when the energy becomes to great?

    Systemically the process while measured in "computerization techniques" this process is one that I see entrenched at the PI Institute, as to holding "this principal" as to the nature of the PI's research status.

    Derek B. Leinweber's Visual QCD* Three quarks indicated by red, green and blue spheres (lower left) are localized by the gluon field.

    * A quark-antiquark pair created from the gluon field is illustrated by the green-antigreen (magenta) quark pair on the right. These quark pairs give rise to a meson cloud around the proton.

    * The masses of the quarks illustrated in this diagram account for only 3% of the proton mass. The gluon field is responsible for the remaining 97% of the proton's mass and is the origin of mass in most everything around us.

    * Experimentalists probe the structure of the proton by scattering electrons (white line) off quarks which interact by exchanging a quantum of light (wavy line) known as a photon.



    Now indeed for me, thinking in relation to the 13th Sphere I would have to ask how and when we loose focus on that discreteness)a particle or a wave?). I now ask that what indeed is the fluidity of the Gluon plasma that we see we have lost the "discrete geometries" to the subject of "continuity?"

    So the question for me then is that if such a case presents itself in these new theoretical definitions, as pointed out in E8, how are we ever to know that such a kaleidescope will have lost it's distinctive lines?

    This would require a change in "math type" that we present such changes to consider the topologies in expression(this fluidity and continuity), in relation to how we see the QCD in developmental aspects.


    In a metric space, it is equivalent to consider the neighbourhood system of open balls centered at x and f(x) instead of all neighborhoods. This leads to the standard ε-δ definition of a continuous function from real analysis, which says roughly that a function is continuous if all points close to x map to points close to f(x). This only really makes sense in a metric space, however, which has a notion of distance.

    Note, however, that if the target space is Hausdorff, it is still true that f is continuous at a if and only if the limit of f as x approaches a is f(a). At an isolated point, every function is continuous.

    Kip Thorne on Space Place Live and Cosmc Colors

    The most important thing is to be motivated by your own intellectual curiosity. KIP THORNE




    Click here to watch Kip Thorne on Space Place Live.

    The "Color of Gravity to Sound" forces perspective. What can I say? It becomes an exercise into an artistic adventure. So there has to be a historical development in any idea to express gravity in such a way. So you develop new ideas, learn that detection methods in the aluminum bar for gravity detection holds ameaning for a new enquiring mind. What was Webber doing? Did Einstein hear gravity in such a way? He knew to measure time in terms of the hot stove and a beautiful girl?

    The "visible" images in the viewer are what we see with our unaided eyes or ordinary telescopes. The other images shown here were made by instruments that detect light our eyes cannot see. Then those images were colored so that we can see what the instrument saw.

    If a "wavelength" appears darkened in the viewer for a particular object, that means we don't yet have an image of that object in that wavelength.


    So we develop our measures and apply our colours. How nice these pictures look? Everybody's view the same.

    The Colour of the Emotive State

    This a person's coloured view of the world around them. The gravity of their situation.

    If we were to say that all life was expressed in such a way what would the vibrancy of our emotive states scream, if love is splashed onto a screen, or "anger" stopping in the red?

    A man sits under heavy questioning. There are no lie detectors attached to his being. No way is there a better way then to know that his voice, his disposition, cannot hide a lie he might like to tell? The colour tells all, and the deception, is the man's grounded position on life and truth he acquired.

    The Ring of Truth

    Savas Dimopoulos:Here’s an analogy to understand this: imagine that our universe is a two-dimensional pool table, which you look down on from the third spatial dimension. When the billiard balls collide on the table, they scatter into new trajectories across the surface. But we also hear the click of sound as they impact: that’s collision energy being radiated into a third dimension above and beyond the surface. In this picture, the billiard balls are like protons and neutrons, and the sound wave behaves like the graviton.


    On the title it is important to understand what is being implied within the context of this post. What came to mind immediately when Bee wrote"Ring of Truth" in her post, "A Theoretically Simple Exception of Everything." Joseph Weber came to mind.

    Joseph Weber 1919 - 2000

    Joseph Weber, the accomplished physicist and electrical engineer, has died at the age of 81. Weber's diverse research interests included microwave spectroscopy and quantum electronics, but he is probably best known for his investigations into gravitational waves.

    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 aluminium 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 sceptical 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.

    Weber was born in 1919 in Paterson, New Jersey, and graduated in 1940. He spent eight years as an electrical engineer in the US Navy, and was assigned as navigator on the aircraft carrier Lexington during World War II. After his resignation from the Navy in 1948, Weber went on to obtain his PhD in 1951 from the Catholic University of America. He was appointed professor of electrical engineering at the University of Maryland, and he moved into the physics department in 1961 when he began his investigations into gravitational waves.

    Weber died on 30 September in Pittsburgh, Pennsylvania. He is survived by his wife, the astrophysicist Virginia Trimble.


    Bee writes about "Ring of Truth" from Lee Smolin's book,
    "But we are also fairly sure that we do not yet have all the pieces. Even with the recent successes, no idea yet has that absolute ring of truth." p. 255 (US hardcover).


    So I pulled this above from Bee's comment blog for further reference. To help make my point about gravitational wave detection and all the kinds of wav(Y)es in which gravity can now be looked at.

    So of course it is necessary to include the commentary from Bee's reference too, Garrett Lisi's comment section, to help one see the complex rotations that speaks to all manifestations(geometrical foresight on complex rotations in dimensional spaces), from the origins of all a particle creations to the elemental understanding given in context of the post by Bee.


    "With the discovery of sound waves in the CMB, we have entered a new era of precision cosmology in which we can begin to talk with certainty about the origin of structure and the content of matter and energy in the universe-Wayne Hu


    Stefan,

    Maybe I have a better chance to understand them when their relation to the original post is more than just the word "gravity" in both of them?

    Your "toying with the way we see gravitational and gravity waves?" Dealing with the objective world with ancient ideas?

    I pointed to the differences.

    Plato:Wherever there are no gravitational waves the spacetime is flat. One would have to define these two variances. One from understanding the relation to "radiation" and the other, "to the perfectly spherically symmetric."


    But still to see such dynamics in terms of the "mathematical abstract" I see see no reason why you would "lesson my points" on helping one to see these differences in the space around us.

    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.


    So I may point to the ways in which one may synthesized the views of the world in relation to not only "sound" as Kris just talks about, but also about how one may transform that sound "to colour."

    3.1 As Cytowic notes, Plato and Socrates viewed emotion and reason as in a kind of struggle, one in which it was vitally important for reason to win out. Aristotle took a more moderate view, that both emotion and reason are integral parts of a complex human soul--a theory proposed by Aristotle in explicit opposition to Platonism (De Anima 414a 19ff). Cytowic appears to endorse the Platonic line, with the notable difference that he would apparently rather have emotion win out.


    Cosmic variance may talk about synesthesia yet you cannot stop the changes such understanding brings to the emotive forces that surround earth and us.

    Such a shift to bulk perspective is not without it's lessons on progressing the views of gravity in "all situations."

    I am not so smart, just that I may see differently then you Stefan. :)

    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 gravitational 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 in spiralling into a black hole.


    Does anybody really understand what is happening when the conceptual foundation allows new perspective to form? New theories to make their way into challenging the very foundations of our reality?

    Every step in the production of the "conceptual framework" is an exercise in how perception is being changed. Can be changed.

    There are moderators of all sorts who govern the information that is being written. How one view can be portrayed and sits in contradiction to the way String theory uses E8 is not the reason one might of suspected problems with acceptance here or there.

    It s a organizational method on how to respond and place it accordingly. Peter is being paranoid? :)

    Production of Gravitational Waves

    "My heart leaps up when I behold A rainbow in the sky."
    William Wordsworth-- My Heart Leaps Up



    This post is based on "the production" and not the detection of gravitational waves.

    It does serve it's purpose, that I explain what I have in terms of detection, that one moves from that process, to actual production of them.:) Now I am not talking about Taylor and Hulse and PSR 1913+16 either.


    Dr. Kip Thorne, Caltech 01-Relativity-The First 20th Century Revolution



    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...



  • Einstein@Home



  • LIGO:



  • Nor am I talking about Kip Thorne, Webber, or Ligo operation for that matter.

    I am actually talking about the creation of gravitational waves.

    Now imagine that you see this "slide of light," and you were to think that in front of you, this would help you see where the gravitational field would be falling away from you. You would be sliding "ahead" from where you pointed and created this effect.

    So now you get the idea here of what I propose in the production of gravitational waves versus the detection of them?:)


    Up until this point in time, I've used the term "generate" to describe the capability of producing a gravitational field, but since I'm not aware of any way of creating a gravitational field from nothing, a more accurate term might be to "access and amplify" a gravitational field. And this is what I mean when I use the term "generate". To understand how gravity is generated or "accessed and amplified", you must first know what gravity is.


    While watching a television program I listened to what he had to say. For people interested in gravity, Quantum or otherwise, this topic helped captured my change in thinking that is postulated, and one I am giving thought right now.

    The Problem


    Gravitational waves are produced when there is a change in the curvature of spacetime. Since the shape of spacetime depends only on how mass is distributed, events that change the distribution of mass cause gravitational waves. It takes events with a lot of energy to make gravitational waves that we can detect because spacetime is not very elastic. Remember the bowling ball analogy? Space-time is like a stiff trampoline, one that only sinks when you put something very heavy on it.


    So if we are to consider such a thing how would I go about it? Perhaps, "jumping up and down?":)


    “Every time you accelerate—say by jumping up and down—you’re generating gravitational waves,” says Rainer Weiss, Professor Emeritus of Physics at MIT. “There’s no doubt of it.” But just standing there won’t cut the mustard. To make a wave, your mass has to both move (have velocity) and have acceleration (change the rate of motion, direction, or both).

    Still, don’t get your hopes up. No matter how fast you jump, sprint, or cartwheel, the resulting warp your waves make on space is so weak that it’s utterly unmeasurable—perhaps 100,000,000,000,000,000,000,000 times less so than the warp made by massive exploding space objects. And LIGO has a tough enough time measuring those.


    So there are questions on my mind, about gravity creation.

    Plato writes:


    Dorigo,

    I am interested as a lay person in the collider experiments and wondered about "gravitational wave production."

    Considering quark gluon levels reached I wondered about the strength and the weakness as a measure of gravitational waves within that collider action. If microscopic blackhole are created then would it be wrong to observe, variation of gravity within the domain of the collider itself?

    regards,


    See following comment posted here.

    Dear Plato,

    quarks are microscopic bodies. The gravitational effects associated with the motion and interaction of masses that small are ridiculously small.

    In theories contemplating a low quantum gravity scale, black holes could in principle be created in high energy collisions, but if a chance of detecting their creation exists, it is not by gravitational effects, which remain billions of billions of billions of billions (and then some) of times smaller than those caused by strong interactions.

    Please check my post on Lisa Randall’s seminar (Sept. 29th), or the one on the seminar given by Steve Giddings last March. There is reading material that I tried to make accessible to most there.

    Cheers,
    T.


    I will be loking at this in much more detail. Something that immediately came to mind is Gran Sasso. "Muon creation" from the particle collisions. See: Neutrino Mixing in Sixty Seconds.

    This summer, CERN gave the starting signal for the long-distance neutrino race to Italy. The CNGS facility (CERN Neutrinos to Gran Sasso), embedded in the laboratory's accelerator complex, produced its first neutrino beam. For the first time, billions of neutrinos were sent through the Earth's crust to the Gran Sasso laboratory, 732 kilometres away in Italy, a journey at almost the speed of light which they completed in less than 2.5 milliseconds. The OPERA experiment at the Gran Sasso laboratory was then commissioned, recording the first neutrino tracks. See Strangelets and Strange Matter


    The Distorted Lense

    It would seem to me that if any lens could direct "the focus of our vision" then why not the focus of the gravitational waves? I mean if there is a "inverse calculation" to waves, it would seem t me that such a process could point to a heavy concentration in terms of blackhole production?


    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.


    As I am reading different thoughts are manifesting and one of these has to do with the "escape velocity of the photon." Why I am not sure at the moment. This used as a measure of determination of whether a blackhole exists? How did we arrive at such a point?


    Albert Einstein (1879–1955)


    One part of the theory of Relativity was inspired when a painter fell off a roof. Einstein found out that while the painter was falling freely, he felt weightless. This led Einstein to realize that gravity was a form of inertia, a result of the way things moved through space - and General Relativity was born.


    It is important for me to recognize the collider process in context of what it is experimentally doing. For me this is demonstrating a "geometrical process" even if it is being taken down to the such "weak gravitational ranges" that I would point to what would manifest,if a tunnelling effect occurred from one location to the next.

    Time travel

    Plato:Thus the initial idea here to follow is that the process had to have a physics relation. This is based on the understanding of anti-particle/particle, and what becomes evident in the cosmos as a closed loop process. Any variation within this context, is the idea of "blackhole anti-particle expression" based on what can be seen at the horizon?Tunneling in Faster then Light


    Warp Drives", "Hyperspace Drives", or any other term for Faster-than-light travel is at the level of speculation, with some facets edging into the realm of science. We are at the point where we know what we do know and know what we don’t, but do not know for sure if faster than light travel is possible.

    The bad news is that the bulk of scientific knowledge that we have accumulated to date concludes that faster than light travel is impossible. This is an artifact of Einstein’s Special Theory of Relativity. Yes, there are some other perspectives; tachyons, wormholes, inflationary universe, spacetime warping, quantum paradoxes...ideas that are in credible scientific literature, but it is still too soon to know if such ideas are viable.

    One of the issues that is evoked by any faster-than-light transport is time paradoxes: causality violations and implications of time travel. As if the faster than light issue wasn’t tough enough, it is possible to construct elaborate scenarios where faster-than-light travel results in time travel. Time travel is considered far more impossible than light travel.


    It would be suspect to me that such travelling in space would allow for the manufacture of gravitational influences to be pointed in the "direction of travel" and allow such slippage away from that current position.

    Gravitational Mass for a Photon

    The relativistic energy expression attributes a mass to any energetic particle, and for the photon



    The gravitational potential energy is then



    When the photon escapes the gravity field, it will have a different frequency




    Since it is reduced in frequency, this is called the gravitational red shift or the Einstein red shift.

    Escape Energy for Photon

    If the gravitational potential energy of the photon is exactly equal to the photon energy then



    Note that this condition is independent of the frequency, and for a given mass M establishes a critical radius. Actually, Schwarzchilds's calculated gravitational radius differs from this result by a factor of 2 and is coincidently equal to the non-relativistic escape velocity expression




    A black hole is an object so massive that even light cannot escape from it. This requires the idea of a gravitational mass for a photon, which then allows the calculation of an escape energy for an object of that mass. When the escape energy is equal to the photon energy, the implication is that the object is a "black hole."


    For more see "Time as a measure.

    By allowing new physics to emerge, what basis is being held relevant then to what is being created in the particle collisions that are indeed faster then light?


    As we know from Einstein’s theory of special relativity, nothing can travel faster than c, the velocity of light in a vacuum. The speed of the light that we see generally travels with a slower velocity c/n where n is the refractive index of the medium through which we view the light (in air at sea level, n is approximately 1.00029 whereas in water n is 1.33). Highly energetic, charged particles (which are only constrained to travel slower than c) tend to radiate photons when they pass through a medium and, consequently, can suddenly find themselves in the embarrassing position of actually travelling faster than the light they produce!

    The result of this can be illustrated by considering a moving particle which emits pulses of light that expand like ripples on a pond, as shown in the Figure (right). By the time the particle is at the position indicated by the purple spot, the spherical shell of light emitted when the particle was in the blue position will have expanded to the radius indicated by the open blue circle. Likewise, the light emitted when the particle was in the green position will have expanded to the radius indicated by the open green circle, and so on. Notice that these ripples overlap with each other to form an enhanced cone of light indicated by the dotted lines. This is analogous to the idea that leads to a sonic boom when planes such as Concorde travel faster than the speed of sound in air

    Fifth Dimensional General Relativity

    It was a gradual process that using Grace to help me see the earth in new ways was paramount to the inclusion principle of electromagnetism contained within the move to GR.I may be mixed up here, and I have no one to say.

    "Color of gravity" assumes that you have seen the colour of gravity in relation to this slide of light. So seeing in such a way would seem relevant in the fifth dimensional perspective.

    In Kaku's preface of Hyperspace, page ix, we find a innocent enough statement that helps us orientate a view that previous to all understanding, is couched in the work of Kaluza.

    In para 3, he writes,

    Similarily, the laws of gravity and light seem totally dissimilar. They obey different physical assumptions and different mathematics. Attempts to splice these two forces have always failed. However, if we add one more dimension, a fifth dimension, to the previous four dimensions of space and time, then equations governing light and gravity appear to merge together like two pieces of a jigsaw puzzle. Light, in fact, can be explained in the fifth dimension. In this way, we see the laws of light and gravity become simpler in five dimensions.


    I would think such a thought here by Kaku would have stimulated the brains of people to see that a direct result is needed in our reality to which such thoughts I am giving would allow you to see gravity in new ways?



    Lagrangian views with regards to relations between the Earth, Moon and Sun would help one to see the general outlay of gravitational influences in space. That is also part of the work I have been following to understand the spacetime fabric and how we may see this in our dealings.
