Direct Observation of NU Tau

Although it is Fermi dated(last modified 07/09/2000) it is good to see parts of this progression in LHC? Does Tau Neutrino have it's roots in other places as well? So sometimes it is nice to see this connection for myself.

first tau-neutrino “appearing” out of several billion of billions muon neutrinos

Layout of the CNGS beam line.
The OPERA neutrino experiment [1] at the underground Gran Sasso Laboratory (LNGS) was designed to perform the first detection of neutrino oscillations in direct appearance mode in the νμ→ντ channel, the signature being the identification of the τ− lepton created by its charged current (CC) interaction [2].

Energy Boost From Shock Front

Main Components of CNGS
A 400 GeV/c proton beam is extracted from the SPS in 10.5 microsecond short pulses of 2.4x1013 protons per pulse. The proton beam is transported through the transfer line TT41 to the CNGS target T40. The target consists of a series of graphite rods, which are cooled by a recirculated helium flow. Secondary pions and kaons of positive charge produced in the target are focused into a parallel beam by a system of two pulsed magnetic lenses, called horn and reflector. A 1 km long evacuated decay pipe allows the pions and kaons to decay into their daughter particles - of interest here is mainly the decay into muon-neutrinos and muons. The remaining hadrons (protons, pions, kaons) are absorbed in an iron beam dump with a graphite core. The muons are monitored in two sets of detectors downstream of the dump. Further downstream, the muons are absorbed in the rock while the neutrinos continue their travel towards Gran Sasso.microsecond short pulses of 2.4x1013 protons per
 For me it has been an interesting journey in trying to understand the full context of a event in space sending information through out the cosmos in ways that are not limited to the matter configurations that would affect signals of those events.

In astrophysics, the most widely discussed mechanism of particle acceleration is the first-order Fermi process operating at collisionless shocks. It is based on the idea that particles undergo stochastic elastic scatterings both upstream and downstream of the shock front. This causes particles to wander across the shock repeatedly. On each crossing, they receive an energy boost as a result of the relative motion of the upstream and downstream plasmas. At non-relativistic shocks, scattering causes particles to diffuse in space, and the mechanism, termed "diffusive shock acceleration," is widely thought to be responsible for the acceleration of cosmic rays in supernova remnants. At relativistic shocks, the transport process is not spatial diffusion, but the first-order Fermi mechanism operates nevertheless (for reviews, see Kirk & Duffy 1999; Hillas 2005). In fact, the first ab initio demonstrations of this process using particle-in-cell (PIC) simulations have recently been presented for the relativistic case (Spitkovsky 2008b; Martins et al. 2009; Sironi & Spitkovsky 2009).
Several factors, such as the lifetime of the shock front or its spatial extent, can limit the energy to which particles can be accelerated in this process. However, even in the absence of these, acceleration will ultimately cease when the radiative energy losses that are inevitably associated with the scattering process overwhelm the energy gains obtained upon crossing the shock. Exactly when this happens depends on the details of the scattering process. See: RADIATIVE SIGNATURES OF RELATIVISTIC SHOCKS

So in soliton expressions while trying to find such an example here in the blog does not seem to be offering itself in the animations of the boat traveling down the channel we are so familiar with that for me this was the idea of the experimental processes unfolding at LHC. The collision point creates shock waves\particle sprays as Jets?


Solitary wave in a laboratory wave channel.
In mathematics and physics, a soliton is a self-reinforcing solitary wave (a wave packet or pulse) that maintains its shape while it travels at constant speed. Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium. (The term "dispersive effects" refers to a property of certain systems where the speed of the waves varies according to frequency.) Solitons arise as the solutions of a widespread class of weakly nonlinear dispersive partial differential equations describing physical systems. The soliton phenomenon was first described by John Scott Russell (1808–1882) who observed a solitary wave in the Union Canal in Scotland. He reproduced the phenomenon in a wave tank and named it the "Wave of Translation".

So in a sense the shock front\horn for me in respect of Gran Sasso is the idea that such a front becomes a dispersive element in medium expression of earth to know that such densities in earth have a means by which we can measure relativist interpretations as assign toward density determinations in the earth.  Yet,  there are things not held to this distinction so know that they move on past such targets so as to show cosmological considerations are just as relevant today as they are while we set up the experimental avenues toward identifying this relationship here on earth.

 For more than a decade, scientists have seen evidence that the three known types of neutrinos can morph into each other. Experiments have found that muon neutrinos disappear, with some of the best measurements provided by the MINOS experiment. Scientists think that a large fraction of these muon neutrinos transform into tau neutrinos, which so far have been very hard to detect, and they suspect that a tiny fraction transform into electron neutrinos. See: Fermilab experiment weighs in on neutrino mystery

When looking out at the universe such perspective do not hold relevant for those not looking past the real toward the abstract? To understand the distance measure of binary star of Taylor and Hulse,  such signals need to be understood in relation to what is transmitted out into the cosmos? How are we measuring that distance? For some who are even more abstractedly gifted they may see the waves generated in gravitational expression. So this becomes a means which which to ask if the binary stars are getting closer then how is this distance measured? You see?

Fermilab experiment weighs in on neutrino mystery
Scientists of the MINOS experiment at the Department of Energy’s Fermi National Accelerator Laboratory announced today (June 24) the results from a search for a rare phenomenon, the transformation of muon neutrinos into electron neutrinos. The result is consistent with and significantly constrains a measurement reported 10 days ago by the Japanese T2K experiment, which announced an indication of this type of transformation.

The results of these two experiments could have implications for our understanding of the role that neutrinos may have played in the evolution of the universe. If muon neutrinos transform into electron neutrinos, neutrinos could be the reason that the big bang produced more matter than antimatter, leading to the universe as it exists today.

The Main Injector Neutrino Oscillation Search (MINOS) at Fermilab recorded a total of 62 electron neutrino-like events. If muon neutrinos do not transform into electron neutrinos, then MINOS should have seen only 49 events. The experiment should have seen 71 events if neutrinos transform as often as suggested by recent results from the Tokai-to-Kamioka (T2K) experiment in Japan. The two experiments use different methods and analysis techniques to look for this rare transformation.
To measure the transformation of muon neutrinos into other neutrinos, the MINOS experiment sends a muon neutrino beam 450 miles (735 kilometers) through the earth from the Main Injector accelerator at Fermilab to a 5,000-ton neutrino detector, located half a mile underground in the Soudan Underground Laboratory in northern Minnesota. The experiment uses two almost identical detectors: the detector at Fermilab is used to check the purity of the muon neutrino beam, and the detector at Soudan looks for electron and muon neutrinos. The neutrinos’ trip from Fermilab to Soudan takes about one four hundredths of a second, giving the neutrinos enough time to change their identities.

For more than a decade, scientists have seen evidence that the three known types of neutrinos can morph into each other. Experiments have found that muon neutrinos disappear, with some of the best measurements provided by the MINOS experiment. Scientists think that a large fraction of these muon neutrinos transform into tau neutrinos, which so far have been very hard to detect, and they suspect that a tiny fraction transform into electron neutrinos.

The observation of electron neutrino-like events in the detector in Soudan allows MINOS scientists to extract information about a quantity called sin213 (pronounced sine squared two theta one three). If muon neutrinos don’t transform into electron neutrinos, this quantity is zero. The range allowed by the latest MINOS measurement overlaps with but is narrower than the T2K range. MINOS constrains this quantity to a range between 0 and 0.12, improving on results it obtained with smaller data sets in 2009 and 2010. The T2K range for sin213 is between 0.03 and 0.28.
“MINOS is expected to be more sensitive to the transformation with the amount of data that both experiments have,” said Fermilab physicist Robert Plunkett, co-spokesperson for the MINOS experiment. “It seems that nature has chosen a value for sin213 that likely is in the lower part of the T2K allowed range. More work and more data are really needed to confirm both these measurements.”
The MINOS measurement is the latest step in a worldwide effort to learn more about neutrinos. MINOS will continue to collect data until February 2012. The T2K experiment was interrupted in March when the severe earth quake in Japan damaged the muon neutrino source for T2K. Scientists expect to resume operations of the experiment at the end of the year. Three nuclear-reactor based neutrino experiments, which use different techniques to measure sin213, are in the process of starting up.
“Science usually proceeds in small steps rather than sudden, big discoveries, and this certainly has been true for neutrino research,” said Jenny Thomas from University College London, co-spokesperson for the MINOS experiment. “If the transformation from muon neutrinos to electron neutrinos occurs at a large enough rate, future experiments should find out whether nature has given us two light neutrinos and one heavy neutrino, or vice versa. This is really the next big thing in neutrino physics.”
The MINOS experiment involves more than 140 scientists, engineers, technical specialists and students from 30 institutions, including universities and national laboratories, in five countries: Brazil, Greece, Poland, the United Kingdom and the United States. Funding comes from: the Department of Energy Office of Science and the National Science Foundation in the U.S., the Science and Technology Facilities Council in the U.K; the University of Minnesota in the U.S.; the University of Athens in Greece; and Brazil's Foundation for Research Support of the State of São Paulo (FAPESP) and National Council of Scientific and Technological Development (CNPq).

Fermilab is a national laboratory supported by the Office of Science of the U.S. Department of Energy, operated under contract by Fermi Research Alliance, LLC.

Seeing Underlying Structures

 There is  gap between,  "Proton Collision ->Decay to Muons and Muon Neutrinos ->Tau Neutrino ->[gap] tau lepton may travel some tens of microns before decaying back into neutrino and charged tracks." Use the case of Relativistic Muons?

 An analysis of four Fermi-detected gamma-ray bursts (GRBs) is given that sets upper limits on the energy dependence of the speed and dispersion of light across the universe. The analysis focuses on photons recorded above 1 GeV for Fermi detected GRB 080916C, GRB 090510A, GRB090902B, and GRB 090926A. Upper limits on time scales for statistically significant bunching of photon arrival times were found and cataloged. In particular, the most stringent limit was found for GRB 090510A at redshift z & 0.897 for which t < 0.00136 sec, a limit driven by three separate photon bunchings. These photons occurred among the first seven super-GeV photons recorded for GRB 090510A and contain one pair with an energy difference of E & 23.5 GeV. The next most limiting burst was GRB 090902B at a redshift of z & 1.822 for which t < 0.161, a limit driven by several groups of photons, one pair of which had an energy difference E & 1.56 GeV. Resulting limits on the differential speed of light and Lorentz invariance were found for all of these GRBs independently. The strongest limit was for GRB 090510A with c/c < 6.09 x 10−21. Given generic dispersion relations across the universe where the time delay is proportional to the photon energy to the first or second power, the most stringent limits on the dispersion strengths were k1 < 1.38 x 10−5 sec Gpc−1 GeV−1 and k2 < 3.04 x 10−7 sec Gpc−1 GeV−2 respectively. Such upper limits result in upper bounds on dispersive effects created, for example, by dark energy, dark matter or the spacetime foam of quantum gravity. Relating these dispersion constraints to loop quantum gravity
energy scales specifically results in limits of M1c2 > 7.43 x 1021 GeV and M2c2 > 7.13 x 1011 GeV respectively. See: Limiting properties of light and the universe with high energy photons from Fermi-detected Gamma Ray Bursts

The point here is that Energetic disposition of flight time and Fermi Calorimetry result point toward GRB emission and directly determination of GRB emission allocates potential of underlying structure W and the electron-neutrino fields?

Fig. 3: An electron, as it travels, may become a more complex combination of disturbances in two or more fields. It occasionally is a mixture of disturbances in the photon and electron fields; more rarely it is a disturbance in the W and the electron-neutrino fields. See: Another Speed Bump for Superluminal Neutrinos Posted on October 11, 2011 at, "Of Particular Significance"
What I find interesting is that Tamburini and Laveder do not stop at discussing the theoretical interpretation of the alleged superluminal motion, but put their hypothesis to the test by comparing known measurements of neutrino velocity on a graph, where the imaginary mass is computed from the momentum of neutrinos and the distance traveled in a dense medium. The data show a very linear behaviour, which may constitute an explanation of the Opera effect: See: Tamburini: Neutrinos Are Majorana Particles, Relativity Is OK

Cohen-Glashow Argument

Bee:And for all I know you need a charge for Cherenkov radiation and neutrinos don't have one.

Fig. 1: Cerenkov radiation involves the nearly continuous emission of photons by a charged particle moving faster than the speed of light in its vicinity. The charged particle gradually radiates away its energy. Cohen-Glashow emission involves the occasional creation, near a speeding neutrino, of an electron-positron pair, in which the neutrino loses a large fraction of its energy in one step.

But these details almost don’t matter, because Cohen and Glashow then put another chunk of powerful evidence on the table. They point out that neutrinos have been observed, at two other experiments, SuperKamiokande and IceCube, 100 to 1000 times more energetic than the neutrinos in OPERA’s beam. These neutrinos come out of the earth having traveled many hundreds or thousands of kilometers across interior of the planet. The fact that these neutrinos did not lose most of their energy while traveling all that distance implies that they, too, did not undergo CG emission. In short, they must have traveled very close to, and conservatively no more than about fifteen parts per billion faster than, the speed of light in empty space. (The limit from IceCube data may be as good as ten parts per trillion!)See: Is the OPERA Speedy Neutrino Experiment Self-Contradictory?

Proton Collision ->Decay to Muons and Muon Neutrinos ->Tau Neutrino ->

.....tau lepton may travel some tens of microns before decaying back into neutrino and charged tracks

 Before I comment on the result, let me give you a little background on the whole thing. Opera is a very innovative concept in neutrino detection. Its aim is to detect tau neutrino appearance in a beam of muon neutrinos. A Six-Sigma Signal Of Superluminal Neutrinos From Opera!

The OPERA result is based on the observation of over 15000 neutrino events measured at Gran Sasso, and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature’s cosmic speed limit. Given the potential far-reaching consequences of such a result, independent measurements are needed before the effect can either be refuted or firmly established. This is why the OPERA collaboration has decided to open the result to broader scrutiny. The collaboration’s result is available on the preprint server arxiv.org

In order to perform this study, the OPERA Collaboration teamed up with experts in metrology from CERN and other institutions to perform a series of high precision measurements of the distance between the source and the detector, and of the neutrinos’ time of flight. The distance between the origin of the neutrino beam and OPERA was measured with an uncertainty of 20 cm over the 730 km travel path. The neutrinos’ time of flight was determined with an accuracy of less than 10 nanoseconds by using sophisticated instruments including advanced GPS systems and atomic clocks. The time response of all elements of the CNGS beam line and of the OPERA detector has also been measured with great precision.


By classifying the neutrino interactions according to the type of neutrino involved (electron-neutrino or muon-neutrino) and counting their relative numbers as a function of the distance from their creation point, we conclude that the muon-neutrinos are "oscillating." See: STATEMENT: EVIDENCE FOR MASSIVE NEUTRINOS FOUND by Dave Casper

We present an analysis of atmospheric neutrino data from a 33.0 kiloton-year (535-day)exposure of the Super-Kamiokande detector. The data exhibit a zenith angle dependent de ficit of muon neutrinos which is inconsistent with expectations based on calculations of the atmospheric neutrino flux. Experimental biases and uncertainties in the prediction of neutrino fluxes and cross sections are unable to explain our observation. . Evidence for oscillation of atmospheric neutrinos

Using the NuMI beam to search for electron neutrino appearance.

The NOνA Experiment (Fermilab E929) will construct a detector optimized for electron neutrino detection in the existing NuMI neutrino beam. The primary goal of the experiment is to search for evidence of muon to electron neutrino oscillations. This oscillation, if it occurs, holds the key to many of the unanswered questions in neutrino oscillation physics. In addition to providing a measurement of the last unknown mixing angle, θ13, this oscillation channel opens the possibility of seeing matter/anti-matter asymmetries in neutrinos and determination of the ordering of the neutrino mass states.See:The NOνA Experiment at Fermilab (E929)

Measurement of the neutrino velocity with the OPERA detector in the CNGS beam

We know already why the neutrinos could go faster and what new experiments this suggests, why it does not imply time travel or violates causality, and why it is somewhat expected for neutrinos. Now let us focus on what kind of superluminal velocity is indicated.See:A Million Times The Speed Of Light

Measurement of the neutrino velocity with the OPERA detectorin the CNGS beam
The OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km with much higher accuracy than previous studies conducted with accelerator neutrinos. The measurement is based on highstatistics data taken by OPERA in the years 2009, 2010 and 2011. Dedicated upgrades of the CNGS timing system and of the OPERA detector, as well as a high precision geodesy campaign for the measurement of the neutrino baseline, allowed reaching comparable systematic and statistical accuracies.

An early arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed of light in vacuum of (60.7 ± 6.9 (stat.) ± 7.4 (sys.)) ns was measured. This anomaly corresponds to a relative difference of the muon neutrino velocity with respect to the speed of light (v-c)/c = (2.48 ± 0.28 (stat.) ± 0.30 (sys.)) ×10-5. See:

Measurement of the neutrino velocity with the OPERA detector

New results from OPERA on neutrino propertieslive from Main Amphitheatre.

“This result comes as a complete surprise,” said OPERA spokesperson, Antonio Ereditato of the University of Bern. “After many months of studies and cross checks we have not found any instrumental effect that could explain the result of the measurement. While OPERA researchers will continue their studies, we are also looking forward to independent measurements to fully assess the nature of this observation.” 

 “When an experiment finds an apparently unbelievable result and can find no artefact of the measurement to account for it, it’s normal procedure to invite broader scrutiny, and this is exactly what the OPERA collaboration is doing, it’s good scientific practice,” said CERN Research Director Sergio Bertolucci. “If this measurement is confirmed, it might change our view of physics, but we need to be sure that there are no other, more mundane, explanations. That will require independent measurements.”See:OPERA experiment reports anomaly in flight time of neutrinos from CERN to Gran Sasso

Have we considered their mediums of expression to know that we have witnessed Cerenkov radiation as a process in the faster than light, to know the circumstances of such expressions to have been understood as backdrop measures of processes we are familiar with. Explain the history of particulate expressions from vast distances across our universe?

The OPERA Detector

This is something very different though and it will be very interesting the dialogue and thoughts shared so as to look at the evidence in a way that helps us to consider what is sound in it's understanding, as speed of light.

QGP Advances

Even the famous helium-3, which can flow out of a container via capillary forces, does not count as a perfect fluid.What black holes teach about strongly coupled particles by Clifford V. Johnson and Peter Steinberg....May of Last Year.

If helium-3 is used in cooling energy containment and was to be considered within LHC, wouldn't such example be applicable as to thinking about capillary routes as holes? Energy loss attributed too?

Layman wondering.

The notion of a perfect fluid arises in many fields of physics. The term can be applied to any system that is in local equilibrium and has negligible shear viscosity η. In everyday life, viscosity is a familiar property associated with the tendency of a substance to resist flow. From a microscopic perspective, it is a diagnostic of the strength of the interactions between a fluid’s constituents. The shear viscosity measures how disturbances in the system are transmitted to the rest of the system through interactions. If those interactions are strong, neighboring parts of the fluid more readily transmit the disturbances through the system (see figure 1). Thus low shear viscosities indicate significant interaction strength. The ideal gas represents the opposite extreme—it is a system with no interactions and infinite shear viscosity.

Perfect fluids are easy to describe, but few substances on Earth actually behave like them. Although often cited as a low-viscosity liquid, water in fact has a substantial viscosity, as evidenced by its tendency to form eddies and whorls when faced with an obstacle, rather than to flow smoothly as in ideal hydrodynamics. Even the famous helium-3, which can flow out of a container via capillary forces, does not count as a perfect fluid. What black holes teach about strongly coupled particles

The interesting thing for me as a layman  was about the theoretic in String Theory research is the idea of pushing perspective back in terms of the Microseconds. So for me it was about looking at collision processes and see how these may be applied to cosmological data as we look out amongst the stars.

At the recent seminar, the LHC’s dedicated heavy-ion experiment, ALICE, confirmed that QGP behaves like an ideal liquid, a phenomenon earlier observed at the US Brookhaven Laboratory’s RHIC facility. This question was indeed one of the main points of this first phase of data analysis, which also included the analysis of secondary particles produced in the lead-lead collisions. ALICE's results already rule out many of the existing theoretical models describing the physics of heavy-ions.
See: 2010 ion run: completed!

This is an important development in my view and I have been following for some time. The last contention in recognition for me was determinations of "the initial state" as to whether a Gas or a Fluid. How one get's there. This is phenomenologically correct as to understanding expressions of theoretic approach and application. Don't let anyone tell you different.

While we understand Microscopic blackholes quickly dissipate, it is of great interest that if such high energy collision processes are evident in our recognition of those natural processes, then we are faced with our own planet and signals of faster then light expressions through the mediums of earth?We have created many backdrops (Calorimeters) experimentally for comparisons of energy expressions. ICECUBE.

It is a really interesting story about the creation of our own universe in conjunction with experimental research a LHC

Our work is about comparing the data we collect in the STAR detector with modern calculations, so that we can write down equations on paper that exactly describe how the quark-gluon plasma behaves," says Jerome Lauret from Brookhaven National Laboratory. "One of the most important assumptions we've made is that, for very intense collisions, the quark-gluon plasma behaves according to hydrodynamic calculations in which the matter is like a liquid that flows with no viscosity whatsoever."

Proving that under certain conditions the quark-gluon plasma behaves according to such calculations is an exciting discovery for physicists, as it brings them a little closer to understanding how matter behaves at very small scales. But the challenge remains to determine the properties of the plasma under other conditions.

"We want to measure when the quark-gluon plasma behaves like a perfect fluid with zero viscosity, and when it doesn't," says Lauret. "When it doesn't match our calculations, what parameters do we have to change? If we can put everything together, we might have a model that reproduces everything we see in our detector."

Space Travel and Propulsion Methods

As a layman, my interest has been mainly focused on gravity and a means to defy it. How one can see in different ways.

The Lagrange Points

In the above contour plot we see that L4 and L5 correspond to hilltops and L1, L2 and L3 correspond to saddles (i.e. points where the potential is curving up in one direction and down in the other). This suggests that satellites placed at the Lagrange points will have a tendency to wander off (try sitting a marble on top of a watermelon or on top of a real saddle and you get the idea). A detailed analysis (PDF link) confirms our expectations for L1, L2 and L3, but not for L4 and L5. When a satellite parked at L4 or L5 starts to roll off the hill it picks up speed. At this point the Coriolis force comes into play - the same force that causes hurricanes to spin up on the earth - and sends the satellite into a stable orbit around the Lagrange point.
Seeing space in a different light helps one to adjust perspective abut the universe and the possibilities of travel. There is indeed a abstractness to such ideas that when one sees the universe in a geometrical way, it helped to push my perspective about tunnels in space. How sound may be used to image WMAP.  The three body problem application toward identification of those L positions.

What position is the Space Station occupying?

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.


Institute for Advanced Studies at Austin, 11855 Research Blvd., Austin, Texas 78759, USA.

A theme that has come to the fore in advanced planning for long-range space exploration is the concept that empty space itself (the quantum vacuum, or spacetime metric) might be engineered so as to provide energy/thrust for future space vehicles. Although far-reaching, such a proposal is solidly grounded in modern physical theory, and therefore the possibility that matter/vacuum interactions might be engineered for space-flight applications is not a priori ruled out [1]. As examples, the current development of theoretical physics addresses such topics as warp drives, traversable wormholes and time machines that provide for such vacuum engineering possibilities [2-6]. We provide here from a broad perspective the physics and correlates/
consequences of the engineering of the spacetime metric.


Concept of the Alcubierre drive, showing the opposing regions of expanding and contracting spacetime that propel the central region
The Alcubierre drive, also known as the Alcubierre metric, is a speculative mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light", although not in a local sense.

The Cross Over Point and Time Travel

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.

I mean sure how is it one can measure time in energy particulate views when it appears all smeared out? It is the collision process itself and what I see in nature as Cascading particles as microscopic blackholes created and then quickly dissipated as decay in those particle showers.

Seeing muon detections that tunnel, and find their way across the globe is something that is interesting, as we can now use them in measure, as to what passes through to what is fabricated there in the LHC, becomes an interesting new tool of climate change or even gravitational inclination in relativistic approaches.

Length contractions is a key word here in microscopic measure.


Juan Martín Maldacena and Joseph Polchinski

Dr. Maldacena and Dr. Polchinski each gave brief lectures related to their work. Both included broad overviews of string theory basics, with Dr. Polchinski noting the importance of "thought experiments" to help physicists make advances in the field. He said that physicists are excited about future experiments using particle accelerators such as the Large Hadron Collider at CERN, where some of these "thought experiments" could be validated.

Dr. Maldacena, who was born in Buenos Aires, also spoke about ICTP's important influence on physics in Argentina, noting that many of his professors had spent time at the Centre. Dr. Maldacena himself has participated in ICTP training programmes and was a director of the Spring School on String Theory for four years.

The Dirac Medal is given in honour of P.A.M. Dirac, one of the greatest physicists of the 20th century and a staunch friend of ICTP, to scientists who have made significant contributions to physics. Recipients are announced annually on Dirac's birthday, 8 August. The Medallists also receive a prize of US $5,000.

Professors Maldacena, Polchinski and Vafa are being honored for their fundamental contributions to superstring theory. Their studies range from early work on orbifold compactifications, physics and mathematics of mirror symmetry, D-branes and black hole physics, as well as gauge theory-gravity correspondence. Their contributions in uncovering the strong-weak dualities between seemingly different string theories have enabled us to learn about regimes of quantum field theory which are not accessible to perturbative analysis. These profound achievements have helped us to address outstanding questions like confinement of quarks and QCD mass spectrum from a new perspective and have found applications in practical calculations in the fluid dynamics of quark gluon plasma.

The dualities have also led string theorists to conjecture that the five different superstring theories in ten space-time dimensions are manifestations of one underlying theory, yet undiscovered, which has been named the M-theory.

Another deep quantum mystery for which physicists have no answer has to do with "tunneling" -- the bizarre ability of particles to sometimes penetrate impenetrable barriers. This effect is not only well demonstrated; it is the basis of tunnel diodes and similar devices vital to modern electronic systems.

Tunneling is based on the fact that quantum theory is statistical in nature and deals with probabilities rather than specific predictions; there is no way to know in advance when a single radioactive atom will decay, for example.

The probabilistic nature of quantum events means that if a stream of particles encounters an obstacle, most of the particles will be stopped in their tracks but a few, conveyed by probability alone, will magically appear on the other side of the barrier. The process is called "tunneling," although the word in itself explains nothing.

Chiao's group at Berkeley, Dr. Aephraim M. Steinberg at the University of Toronto and others are investigating the strange properties of tunneling, which was one of the subjects explored last month by scientists attending the Nobel Symposium on quantum physics in Sweden.

"We find," Chiao said, "that a barrier placed in the path of a tunnelling particle does not slow it down. In fact, we detect particles on the other side of the barrier that have made the trip in less time than it would take the particle to traverse an equal distance without a barrier -- in other words, the tunnelling speed apparently greatly exceeds the speed of light. Moreover, if you increase the thickness of the barrier the tunnelling speed increases, as high as you please.

"This is another great mystery of quantum mechanics."
Signal Travels Farther and Faster Than Light By MALCOLM W. BROWNE

You and I know it as a time machine. Physicists, on the other hand, call it a "closed timelike curve." Below, feast on the concepts and conjectures, the dialects and definitions that physicists rely on when musing about the possibility of time travel. If this list only whets your appetite for more, we recommend you have a gander at the book from which we excerpted this glossary: Black Holes and Time Warps: Einstein's Outrageous Legacy, by Kip S. Thorne (Norton, 1994).

    Oh Dear!... How Technology has Changed Things

    Mathematics, rightly viewed, possesses not only truth, but supreme beautya beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as in poetry.--BERTRAND RUSSELL, Study of Mathematics

    The "Talking Pictures" Projection Wagon-
    In the 1920's about the only entertainment that came to the rural community of Leakey, Texas was the traveling tent shows. This form of family entertainment would come to the canyon about once a year to the delight of all. Everyone looked forward to the horse drawn wagons that brought the much anticipated entertainment to town. In later years the horses were replaced by the Model T Fords but this form of transportation did not deter the excitement.

    It is important sometimes to hone in on exactly what sets the mind to have it exemplify itself to a standard that bespeaks to the idealizations that can come forward from a most historical sense. It is in this way that while one can envision where the technological views have replaced the spoken word in movie pictures, we can see the theatre above as an emblazoned realization of what changes has been brought to society and what may have been lost in some peoples eyes.

    This is a photograph of author and philosopher Robert M. Pirsigtaken by Ian Glendinning on the eve of the Liverpool conference of 7th July 2005.
    What is in mind is a sort of Chautauqua...that's the only name I can think of for the traveling tent-show Chautauquas that used to move across America, this America, the one that we are now in, an old-time series of popular talks intended to edify and entertain, improve the mind and bring culture and enlightenment to the ears and thoughts of the hearer. The Chautauquas were pushed aside by faster-paced radio, movies and TV, and it seems to me the change was not entirely an improvement. Perhaps because of these changes the stream of national consciousness moves faster now, and is broader, but it seems to run less deep. The old channels cannot contain it and in its search for new ones there seems to be growing havoc and destruction along its banks. In this Chautauqua I would like not to cut any new channels of consciousness but simply dig deeper into old ones that have become silted in with the debris of thoughts grown stale and platitudes too often repeated.

    I wanted to take the conversation and book presented by Phil and immortalize it in a way by laying it out for examination. Regardless of my opinions and viewpoint, the world goes on and the written work of Robert Pirsig persists as a "object of the material." In the beginning, no matter the choice to illuminate the ideal, it has been transgressed in a way by giving the symbols of language to a discerning mind and verily brought to that same material world for examination. How ever frustrating this may seem for Pirsig, it is a fact of light that any after word will reveal more then what was first understood. Reflection has this way about it in the historical revelation, of how the times are changing. Things dying and becoming new. The moon a reflection of the first light.

    The conclusion of the whole matter is just this,—that until a man knows the truth, and the manner of adapting the truth to the natures of other men, he cannot be a good orator; also, that the living is better than the written word, and that the principles of justice and truth when delivered by word of mouth are the legitimate offspring of a man’s own bosom, and their lawful descendants take up their abode in others. Such an orator as he is who is possessed of them, you and I would fain become. And to all composers in the world, poets, orators, legislators, we hereby announce that if their compositions are based upon these principles, then they are not only poets, orators, legislators, but philosophers.
    Plato, The Dialogues of Plato, vol. 1 [387 AD] PHAEDRUS.


    IN announcing himself in the written work with regards to the IQ given in signalling the identity of the character Phaedrus, it was important that one see this in a way that excuses are not made, and allowances not be set forth for what was to become the lone wolf. John Nash too, had his excursions into the bizarre as well, was to know that in the "end of his synopsized life," a certain contention that he had to deal with in this inflection of his disease, as part of his make-up. Was to deal with, while now, he continues to move on with his life. He is aware of the intrusions that personage can do as it infringes from the periphery, as ghosts of his mind too.

    To me in reading John Nash's biography in historical movie drama, was to bring attention to what cannot be condoned by exception, when allowing genius to display it's talents, while causing a disruption not only to themself, but to see the elite make allowances for these transgressions. Pattern seeking is not to be be rifting the idea, that we cannot look into the very structure of reality and see what makes it tick? Just that we do not get lost in travelling the journey.

    Practising escapism was to deny oneself the responsibility of becoming whole. To allow for genius, as an exception, would mean to not recognize that the intellect is part and parcel of the greater whole of the person called Robert Pirsig or John Nash.

    Who of us shall placate failure as a sure sign of genius and allow the student 's failure as acceptable? This was a transgression seen from another perspective and as afterthought realized in a mistaken perception "about broadcasting Phaedrus" as some towering voice from the past as relevant in todays world, because of the location and time in history?


    Click on link Against symmetry (Paris, June 06)

    While I may use the alias of Plato and look at the substance of his written work, it is also from that view point such a discussion had to take place within the context of the written prose about two people in this Socratic method, that while worlds in the dialogues existed in speech, no such persons were there at the time. Yet, such thoughts are transmitted and established in that historical sense, and moved forward to this time.

    Against symmetry (Paris, June 06)

    To me there are two lines of thought that are being established in science that in Lee Smolin's case is used to move away from the thinking of the idea of Plato's symmetry by example. To see such trademarks inherent in our leaders of science is too wonder how they to, have immortalize the figures of speech, while trying hard to portray the point of view that has been established in thought. These signatures have gone from Heisenberg to Hooft. And the list of names who have embedded this move to science, as a education tool, that is always inherent in the process. That reference is continually made.

    IN this sense I do not feel I had done anything wrong other then to ignite the idealization I have about what that sun means to me, as the first light in a psychological sense. Where it resides in people. How divorce we can be from it while going on about our daily duties existing in the world. That there also resides this "experience about our beginnings." To ignite what the word of geometrics has done in the abstract sense. How much closer to the reality such a architecture is revealed in Nature's way, to know that we had pointed our observations back inside, to reveal the world outside.

    The Plane of Simultaneity

    This blog entry was constructed to reply to the conversation that is going on in the issue of the "Block Universe."


  • Penrose and Quanglement

  • Entanglement and the New Physics

  • In the past, teleportation has only been possible with particles of light Image: Rainer Blatt

    It's useless sometimes to just lay there while these thoughts accumulate in one's mind, as one weaves together the picture that is forming, and whence it come from this unification process, and after a time, one then thinks about the abilities of mind to gather and consolidate.

    By taking advantage of quantum phenomena such as entanglement, teleportation and superposition, a quantum computer could, in principle, outperform a classical computer in certain computational tasks. Entanglement allows particles to have a much closer relationship than is possible in classical physics. For example, two photons can be entangled such that if one is horizontally polarized, the other is always vertically polarized, and vice versa, no matter how far apart they are. In quantum teleportation, complete information about the quantum state of a particle is instantaneously transferred by the sender, who is usually called Alice, to a receiver called Bob. Quantum superposition, meanwhile, allows a particle to be in two or more quantum states at the same time

    So let me begin first by saying that given this process we can connect this world line across the expanse of space, is, more or less the understanding that this is to be the means in which these new forms of communication in science are leading as we expound the future, and what it shall become in our present moments.

    See: Central theme is the Sun You can "click" on picture as well, or, use mouse to hover over image, for additional reading

    So you look at the sun, and what new ways can we can perceive and accumulating the data of what connects this "distance and time," one will be all the smarter when they realize that the results of experimental verifications are at present being given, and as such, what shall these examples serve, but to remind one that new experiences continue to bring new innovations to the forefront.

    Lightcone Projection- see mathematical basis here for the introduction of what will become the basis of determinations, the "decomposable definition" of these new forms of communication.

    The basis for these thoughts are the developing views based on the light cone. It was not my reasons alone in which such an idea was used to support an conjecture about, so, by these very reasons I thought it best to explain what such simultaneity can do as we hold these views about "distance and time" as we follow this world line across the expanse of the universe.

    The grey ellipse is moving relativistic sphere, its oblate shape due to Lorentz contraction. Colored ellipse is visual image of the sphere. Background curves are a xy-coordinates grid which is rigidly linked to the sphere. It is shown only at one moment in time.See here for reference and animations.

    Okay, so we have this event that happens in time. How are we to measure what the sun is suppose to be, if we did not have some information about the depth of perception that is needed in order to create this image for consumption?

    Such comparative views are needed that are current, and, "in experimental stages" to help us discern what it means for "Galactic Communication" which we will employ as we measure the distance of this world line.:)

    Such distances "can be elevated in my view," and such instantaneous recognitions are to be the associative values I place on how we can now see the "bulk perspective" and the graviton's condensation we can now assign to the cosmos?

    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
    See:What is Cerenkov Radiation?

    It is thusly, that such events in time produce information for us, that help us to look at the universe in new ways, and as such, information can be used to build new devices that penetrate beyond the confines we finds photons experience in their limitations.( please Phil take note of, in bold)
