Navy Patent to modify Mass / Inertia

Patent for a craft using an Inertial Mass Reduction Device   patent number 10,144,532B2

It was brought to my attention that a researcher for the U.S. Navy had patented a device for the reduction of mass / inertia,  last December, on work he has been doing  for the last 12 years.  There are many citations of papers of his own as well as work done by others,

After reading the patent claims it appears to me that this is a proposed device patent meant to cover the possibilities rather then an actual device. The author seems to use a great deal of techno-babble to dance around,  Not saying Aether,  to describe the EMF manipulation of the near to the craft, space, to reduce the effects of Mass / Inertia by creating a richly confused, 3 Dimensional field…pg

The Great Coil

In this configuration the black coils are the primary and the white above is the necklace coils. Each of the necklace coils is a single loop terminated at a condenser unit distributed around the circumference of the disk along with the driving primary.

The Original Device

The original device was constructed of welded polypropylene, the bulge rings were built in condensers that were terminations of a necklace of wired loops  bundled with the primary loop of the Great Tesla coil. During early testing the condensers failed and could not be repaired. All of this outer works was cut away to salvage the Great Coil.

Tesla Coil plasma jet

Flat spiral wound tesla coil with central pincushion/plasma jet

The central part of this device is the flat wound spiral coil. This coil is created from about 1200ft of 14 gauge copper wire, 120 turns, at 5 turns to the inch, fixed with 5/32″ polypropylene rod welded to the 1/2 inch thick polypropylene deck. The insulation value between winding turns  was tested to 40,000 volts per turn or 4 million volts of stress for the entire coil. The coil center termination is a 8 inch disk with pins set in a 1/4 inch grid for 16 pins per inch square. The pincushion is inside a polypropylene forcing cone that terminates with a 2 inch plasma conduit. The necklace bundle is just visible inside the ring of the left picture, the central discoloration is the coil it’s self spiraling out from the pincushion/ plasma cone. During initial testing of the device, it was being directly powered from the 15,000 volt transformer when a lead came loose and began arching. The coil went into full Tesla mode of about 2 million volts at the pincushion. A violet plasma jet 6 feet high erupted from the cone! After 25-30 seconds the loose wire came free and the system died.

Some of the built in condensers were damaged and could not be repaired. The Great Coil was removed from the damaged device for further use as it would be very difficult to replace …pg

@Jim2:

It is looking like pervasive “fields” are all that is real, and “particles” are just what you get when something pokes the field. (So a photon hitting the “electron field” causes the “electron particle” to come into being and changes the “2 slot” outcome to the particle form… )

Basically, if we don’t look then everything is a field. It is when we look that it becomes particles…

Isn’t QM fun? 8-} /sarc;

Maybe a lot of the problem with QM is that we can visualise waves OK, and we know about particles and how they collide, and neither the maths nor the visualisation work that well for something that is both at the same time. This isn’t helped by the Copenhagen interpretation, which tells us that it’s only when we look that the wave functions “collapse” into a single result from being indeterminate before we look. Given the age of the universe, and the lack of people to look and measure, it makes sense that things happen whether we look or not. That problem of only having a real result when someone measures it was got over with Bohmian Mechanics, where a “guiding wave” determines the position and direction of a real particle (which makes the wave and the particle there at the same time, and thus things can happen without anyone to measure them). However, this explanation wasn’t chosen, possibly because it effectively posits an Aether (the medium that the guiding wave exists in), and people were trying to go away from anything Aether-like. As I’ve said before, though, if you’re going to have waves of any sort, then as far as we can tell *something* will be waving, and a model with inertial minuscule particles with springs between them is bound to work for a lot of the properties. Basically, you can’t get away from some sort of Aether, even if you rename it as spacetime and say there can be waves in spacetime, unless of course you try to make a model where waves don’t exist and it’s only particles. Since a particle model isn’t going to match reality when it comes to diffraction unless you give the particles some wave properties, and again that implies something being waved, finding a non-paradoxical description has so far escaped us.

At the heart of QM we thus have paradox, which tells us we haven’t yet got a good description of what is actually happening. The models we’ve got mostly work pretty well despite the paradox, though, so it’s the best we’ve got at the moment and mostly we ignore the paradoxes and choose the description of particle or wave depending on which one gives the right answer. Another problem with current theory is that it has inconvenient infinities turning up in the maths. Where these turn up, the technique of “renormalisation” is used, which basically means we ignore the infinities and take them out of the equations, and the rest of the equation then gives the right answer. It’s a fudge, and wasn’t liked at the time it was introduced (can’t remember who by), but sorts the problem. http://www.volkerschatz.com/science/renorm.html . Wikipedia has a nice explanation, too, that goes quite a bit deeper.

One thing that bugs me about all this complex maths is that it’s logical that the particles/waves themselves don’t have the capacity to do all the partial derivatives and integrations to work out where they ought to be. They really should simply react to the forces they see at any point in time (here and now forces and what happens as a result) and though the resultant path may be a little complex such as a conic section, it still ought to be calculable using numerical simulation where we use timesteps and the configuration/forces at each point and thus step through positions of the constituent parts.

Of course, all these theories assume momentum is absolutely conserved in an interaction, and that apart from borrowing/returning to the Heisenberg energy bank, that energy is conserved too. That may not be a valid assumption. It’s almost certainly the net result after an interaction (we normally see energy and momentum conserved), but may not be valid during the interaction. If inertia is quantised (as seems to be true from cosmological observations) then this will apply at the particle level too, and rather than being a continuous range, momentum can only be exchanged (or changed) in quanta. It’s possible that this may change the maths quite a lot. A small force won’t thus affect the velocity (below the necessary force to jump to the next momentum level), and the path of a particle won’t be a smooth curve but instead a series of straight lines as the momentum has step-changes. I figure that might make some difference to the calculations….

Feynman was required reading when I was learning physics. He was good at explaining things, and where he found things that didn’t make sense he changed them so they did make sense. Probably killed a few sacred cows on the way, and his personal life was unconventional too. I see nothing wrong in watching his lectures for entertainment. I haven’t the time this morning, so I’ll watch them somewhat later. More fun than a Marvel blockbuster with fights between groups of people with magic powers.

@Simon; Excellent essay on the logic of the problem of waves that appear to be particles, particles that behave as waves. Quantaize the medium, Call it what you want. I prefer Aether and this results in Mass/Inertia being external to Mater, the thing that matters to me…pg

If you “kick” the Aether hard enough (voltage) and fast enough (frequency) It will kick back hard. Just like the results in a Tesla coil operation. If you are operating a cone shape field by pulsing a signal over a cone or saucer shape within the high voltage/high frequency field you are operating a linear motor within the activated Aether.

A vacuum test campaign evaluating the impulsive thrust performance of a tapered radio-frequency test article excited in the transverse magnitude 212 mode at 1937 MHz has been completed. The test campaign consisted of a forward thrust phase and reverse thrust phase at vacuum with power scans at 40, 60, and 80 W. The test campaign included a null thrust test effort to identify any mundane sources of impulsive thrust; however, none were identified. Thrust data from forward, reverse, and null suggested that the system was consistently performing.

From paper;  Discussion  

    Before providing some qualitative thoughts on the proposed physics potentially at work in the tapered RF test articles, it will be useful to provide a brief background on the supporting physics lines of thought. In short, the supporting physics model used to derive a force based on operating conditions in the test article can be categorized as a nonlocal hidden-variable theory, or pilot-wave theory for short.

Pilot-wave theories are a family of realist interpretations of quantum mechanics that conjecture that the statistical nature of the formalism of quantum mechanics is due to an ignorance of an underlying more fundamental real dynamics, and that microscopic particles follow real trajectories over time just like larger classical bodies do. The first pilot-wave theory was proposed by de Broglie in 1923 [4], where he proposed that a particle interacted with an accompanying guiding wave field, or pilot wave, and this interaction was responsible for guiding the particle along its trajectory, orthogonal to the surfaces of constant phase. In 1926, Madelung [5] published a hydrodynamic model of quantum mechanics by recasting the linear Schrödinger equation into hydrodynamic form, where the Planck constant was analogous to a surface tension σσ in shallow-water hydrodynamics and vacuum fluctuations were the reason for quantum mechanics. In 1952, Bohm [6,7] published a pilot-wave theory where the guiding wave was equivalent to the solution of the Schrödinger equation and a particle’s velocity was equivalent to the quantum velocity of probability. Soon after, the Bohmian mechanics line of thinking was extended by others to incorporate the effects of a stochastic subquantum realm, and de Broglie augmented his initial pilot-wave theory with this approach in 1964 [8], adopting the parlance “hidden thermodynamics.” A family of models categorized as vacuum-based pilot-wave theories or stochastic electrodynamics (SED) [9] further explored the concept that the electromagnetic vacuum fluctuations of the zero point field represent a natural source of stochasticity in the subquantum realm and provide classical explanations for the origin of the Planck constant, Casimir effect, ground state of hydrogen, and much more.

It should be noted that the pilot-wave domain experienced an early setback when von Neumann [10] published an impossibility proof against the idea of any hidden-variable theory. This and other subsequent impossibility proofs were later discredited by Bell 30 years later in 1966 [11], and Bell went on to say in the preface of his 1987 book [12] that the pilot wave eliminated the shifty boundary between wavy quantum states on the one hand and Bohr’s classical terms on the other: said simply, there was a real quantum dynamics underlying the probabilistic nature of quantum mechanics.

Although the idea of a pilot wave or realist interpretation of quantum mechanics is not the dominant view of physics today (which favors the Copenhagen interpretation), it has seen a strong resurgence of interest over the last decade based on some experimental work pioneered by Couder and Fort [13]. Couder and Fort discovered that bouncing a millimeter-sized droplet on a vibrating shallow fluid bath at just the right resonance frequency created a scenario where the bouncing droplet created a wave pattern on the shallow bath that also seemed to guide the droplet along its way. To Couder and Fort, this seemed very similar to the pilot-wave concept just discussed and, in subsequent testing by Couder and others, this macroscopic classical system was able to exhibit characteristics thought to be restricted to the quantum realm. To date, this hydrodynamic pilot-wave analog system has been able to duplicate the double slit experiment findings, tunneling, quantized orbits, and numerous other quantum phenomena. Bush put together two thorough review papers chronicling the experimental work being done in this domain by numerous universities [14,15].

In addition to these quantum analogs, there may already be direct evidence supportive of the pilot-wave approach: specifically, Bohmian trajectories may have been observed by two separate experiments working with photons [16,17]. Reconsidering the double slit experiment with the pilot-wave view, the photon goes through one slit, and the pilot wave goes through both slits. The resultant trajectories that photons follow arTruespacee continuous real trajectories that are affected by the pilot wave’s probabilistic interference pattern with itself as it undergoes constructive and destructive interference due to reflections from the slits.

In the approach used in the quantum vacuum plasma thruster (also known as a Q thruster) supporting physics models, the zero point field (ZPF) plays the role of the guiding wave in a similar manner to the vacuum-based pilot-wave theories. To be specific, the vacuum fluctuations (virtual fermions and virtual photons) serves as the dynamic medium that guides a real particle on its way. Two recent papers authored by members of this investigation team explored the scientific ramifications of this ZPF-based background medium. The first paper [18] considered the quantum vacuum at the cosmological scale in which a thought experiment applied to the Einstein tensor yielded an equation that related the gravitational constant to the quantity of vacuum energy in the universe, implying that gravity might be viewed as an emergent phenomenon: a long wavelength consequence of the quantum vacuum. This viewpoint was scaled down to the atomic level to predict the density of the quantum vacuum in the presence of ordinary matter. This approach yielded a predicted value for the Bohr radius and electron mass with a direct dependency on dark energy. The corollary from this work pertinent to the q-thruster models is that the quantum vacuum is a dynamic medium and could potentially be modeled at the microscopic scale as an electron-positron plasma. The quantum vacuum around the hydrogen nucleus was considered in much more detail in the second paper [19]. Here, the energy density of the quantum vacuum was shown to theoretically have a 1/r41/r4 dependency moving away from the hydrogen nucleus (or proton). This 1/r41/r4 dependency was correlated to the Casimir force, suggesting that the energy density in the quantum vacuum is dependent on geometric constraints and energy densities in electric/magnetic fields. This paper created a quasi-classical model of the hydrogen atom in the COMSOL Multiphysics software (COMSOL is not an acronym) that modeled the vacuum around the proton as an electron-positron plasma. These analysis results showed that the n=1n=1 to 7 energy levels of the hydrogen atom could be viewed as longitudinal resonant acoustic wave modes in the quantum vacuum. This suggests that the idea of treating the quantum vacuum as a dynamic medium capable of supporting oscillations might be valid. If a medium is capable of supporting acoustic oscillations, this means that the internal constituents were capable of interacting and exchanging momentum.

If the vacuum is indeed mutable and degradable as was explored, then it might be possible to do/extract work on/from the vacuum, and thereby be possible to push off of the quantum vacuum and preserve the laws of conservation of energy and conservation of momentum. It is proposed that the tapered RF test article pushes off of quantum vacuum fluctuations, and the thruster generates a volumetric body force and moves in one direction while a wake is established in the quantum vacuum that moves in the other direction.

A vacuum test campaign that used an updated integrated test article and optimized torsion pendulum layout was completed. The test campaign consisted of a forward thrust element that included performing testing at ambient pressure to establish and confirm good tuning, as well as subsequent power scans at 40, 60, and 80 W, with three thrust runs performed at each power setting for a total of nine runs at vacuum. The test campaign consisted of a reverse thrust element that mirrored the forward thrust element. The test campaign included a null thrust test effort of three tests performed at vacuum at 80 W to try and identify any mundane sources of impulsive thrust; none were identified. Thrust data from forward, reverse, and null suggested that the system was consistently performing at 1.2±0.1  mN/kW1.2±0.1  mN/kW, which was very close to the average impulsive performance measured in air. A number of error sources were considered and discussed. Although thermal shift was addressed to a degree with this test campaign, future testing efforts should seek to develop testing approaches that are immune to CG shifts from thermal expansion. As indicated in Sec. II.C.8, a modified Cavendish balance approach could be employed to definitively rule out thermal. Although this test campaign was not focused on optimizing performance and was more an exercise in existence proof, it is still useful to put the observed thrust-to-power figure of 1.2  mN/kW1.2  mN/kW in context. The current state-of–the-art thrust to power for a Hall thruster is on the order of 60  mN/kW60  mN/kW. This is an order of magnitude higher than the test article evaluated during the course of this vacuum campaign; however, for missions with very large delta-v requirements, having a propellant consumption rate of zero could offset the higher power requirements. The 1.2  mN/kW1.2  mN/kW performance parameter is over two orders of magnitude higher than other forms of “zero-propellant” propulsion, such as light sails, laser propulsion, and photon rockets having thrust-to-power levels in the 3.336.67  μN/kW3.33–6.67  μN/kW (or 0.00330.0067  mN/kW0.0033–0.0067  mN/kW) range.     G.

I guess they will need Aether for this thing to work.

As they only used 300 volts as the bias field, They will need to study Tesla’s work, as MUCH higher voltages will be needed to really get traction on the stuff of space. At least 100 times greater to get real traction.

GRAVITATIONAL WAVES DETECTED 100 YEARS AFTER EINSTEIN’S PREDICTION    https://wattsupwiththat.files.wordpress.com/2016/02/gravity-wave-space.jpg?w=720&h=443

 A pictorial representation of gravity waves in the fabric of space caused by 2 black holes spiraling together

Laser Interferometer Gravitational wave Observatory:

For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window onto the cosmos.

Gravitational waves carry information about their dramatic origins and about the nature of gravity that cannot otherwise be obtained. Physicists have concluded that the detected gravitational waves were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole. This collision of two black holes had been predicted but never observed.
The gravitational waves were detected on September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC) by both of the twin Laser Interferometer Gravitational-wave Observatory
(LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA.
The LIGO Observatories are funded by the National Science Foundation (NSF), and were conceived, built, and are operated by Caltech and MIT. The discovery, accepted for publication in the journal Physical Review Letters, was made by the LIGO Scientific Collaboration.

Basic Design of the LIGO Interferometer
Layout of the LIGO Interferometer that measures the warpage of the earth as the force passes through the material of the planet. Lasers measure the differences in distance between the detectors as the earth is effected by the passing wave. The use of two observatories revels the direction of the point of origin.
At each observatory, the two-and-a-half-mile (4-km) long L-shaped LIGO interferometer uses laser light split into two beams that travel back and forth down the arms (four-foot diameter tubes kept under a near-perfect vacuum). The beams are used to monitor the distance between mirrors precisely positioned at the ends of the arms. According to Einstein’s theory, the distance between the mirrors will change by an infinitesimal amount when a gravitational wave passes by the detector. A change in the lengths of the arms smaller than one-ten-thousandth the diameter of a proton, (10 to the-19) meter, can be detected.

Aether or Quanta ?

 

Aether has been in favor and out, for hundreds of years. About 100 years at a time for or against.  As we progress into the 21st century, once more it progresses back into consideration. In the early days of the study of electrical /electronic phenomenon it was posited that the propagation of Electro-Motive Force or EMF required a medium, Aether or ether,  for the radiation waves to effect and travel in. Maxwell proposed that light is an undulation in the same medium that is the cause of electric and magnetic phenomena. At the end of the 19th century Quantum particles became the latest thing as new atomic energy theories were promulgated. At the same time, a definitive experiment was conducted with much fanfare to prove the existence and flow of Aether as the Earth traveled in its’ orbit. The experiment failed to find any proof of Aether existence. This was declared by proponents of Quantum Physics that theirs’ was the only way and that Aether DID NOT EXIST! They claimed that they had no need for Aether to calculate their physics but their formulas all included “fudge factors” constants that supplant for that need.

In my opinion the failure was due to an incorrect understanding of fluid dynamics involved and gravitational effects of the Earth, Sun and the Solar System traveling within this medium. A number of later experiments detected indications of the existence of “Something” where there should be nothing. Astrophysicists of the last of the 20th century and beginning of the 21st have determined that over 84% of the apparent mass of the Universe can not be accounted for within the visible and projected not visible matter that makes up the Universe. Where is this mass hidden? What is this hidden mass? So called Dark matter or dark mass, what is it? Along with Dark Energy, these things constitute over 95% of the total constituents of the Universe. This thing that we do not detect but can only infer from the the behavior of things that we can observe.

Much like Einstein, I began my investigation into mass/inertia and gravity with light. How does light travel through space? How can light travel through Trillions of miles of space without change or loss of speed? How can this thing exhibit characteristics of both wave and particle? And just how can it exhibit one speed only, regardless of the speed and direction of its’ creation and detection. What is this thing, wave or particle? To the good, I do have an additional 100 years of scientific research to draw on during my examinations.

The model that I have come up with is that Aether is charge bubbles in chaos. As long as that charge is in chaos there is no signature to detect. That chaos is aligned or organized under EMF influence. While organized there is an EMF field that can be detected, That EMF travels in/on the highly compressed minute charge bubbles of the Aether. Research claimed that the speed of light travel through the vacuum of space as if were in an atmosphere compressed to 10,000psi. Remember charge pushes, repels charge.

Quanta energy transfer ; electrons, photons, neutrinos are just energy information traveling through these bubbles. Every EMF action causes an equal and opposite reaction from the neighboring bubbles, a perfect elastic that tends to concentrate the energy to the center of its’ path. If you drain that energy with a detection you “see” a particle that behaves as if it were a wave, but really only the energy is delivered. So if you had an Electron or Photon in your hand it actually would be a charge bubble or Quanta of charge that has a particular charge signature. All detection requires a Quanta of energy to create a signal in the detector because that is how much is required to make a valance change in an atom in the detector. We “see” particles because we “see” units of energy. Without a Quanta of energy there is no signal of detection. Imagine if you will, a long rod of copper or glass, wire or fiber. If you poke a quanta of energy into one end, a quanta of energy must jump out at the other end. This is because the electronic stress within the conductor must maintain balance. The energy information is transferred not a particle. The quanta that jumped out of the conductor is not the one that went in. That movement of energy information moves at the conduction speed of that material.
Electrons, photons, neutrinos, etc. are all Aether with different electronic signatures caused by differences in the 3 dimensions of charge in motion.

Mass/inertia of matter is an external effect in the Aether caused by the internal low or lack of charge of protons and high charge of electron shells. The charge of Aether and the resistance of change in retaliative motion of charges in the Aether. Charge in motion resists changes in its’ velocity, strength, in all 3 dimensions. Just like mass/inertia of matter. They are interchangeable.

Gravity is caused by the difference of charge between Aether and Matter. These causes a linear warpage in the atomic dielectric or position of the nucleus within the Electron shell or atomic surface of matter.  This electronic linear deflection of the atomic center of gravity is the cause of the apparent acceleration of Gravity caused by the matter attempting to center its’ mass within its’ physical shell….pg

Cal Tech/JPL proposes dark matter hair

This artist's rendering zooms in on what dark matter "hairs" might look like around Earth
The root of a dark matter hair produced from particles going through Jupiter’s core would be about 1 trillion times denser than average.

The solar system might be a lot hairier than we thought.

A new study publishing this week in the Astrophysical Journal by Gary Prézeau of NASA’s Jet Propulsion Laboratory, Pasadena, California, proposes the existence of long filaments of dark matter, or “hairs.”

Dark matter is an invisible, mysterious substance that makes up about 27 percent of all matter and energy in the universe. The regular matter, which makes up everything we can see around us, is only 5 percent of the universe. The rest is dark energy, a strange phenomenon associated with the acceleration of our expanding universe.

Neither dark matter nor dark energy has ever been directly detected, although many experiments are trying to unlock the mysteries of dark matter, whether from deep underground or in space.

Based on many observations of its gravitational pull in action, scientists are certain that dark matter exists, and have measured how much of it there is in the universe to an accuracy of better than one percent. The leading theory is that dark matter is “cold,” meaning it doesn’t move around much, and it is “dark” insofar as it doesn’t produce or interact with light.

Galaxies, which contain stars made of ordinary matter, form because of fluctuations in the density of dark matter. Gravity acts as the glue that holds both the ordinary and dark matter together in galaxies.

According to calculations done in the 1990s and simulations performed in the last decade, dark matter forms “fine-grained streams” of particles that move at the same velocity and orbit galaxies such as ours.

“A stream can be much larger than the solar system itself, and there are many different streams crisscrossing our galactic neighborhood,” Prézeau said.

Prézeau likens the formation of fine-grained streams of dark matter to mixing chocolate and vanilla ice cream. Swirl a scoop of each together a few times and you get a mixed pattern, but you can still see the individual colors.

“When gravity interacts with the cold dark matter gas during galaxy formation, all particles within a stream continue traveling at the same velocity,” Prézeau said.

But what happens when one of these streams approaches a planet such as Earth? Prézeau used computer simulations to find out.

His analysis finds that when a dark matter stream goes through a planet, the stream particles focus into an ultra-dense filament, or “hair,” of dark matter. In fact, there should be many such hairs sprouting from Earth.

A stream of ordinary matter would not go through Earth and out the other side. But from the point of view of dark matter, Earth is no obstacle.  According to Prézeau’s simulations, Earth’s gravity would focus and bend the stream of dark matter particles into a narrow, dense hair.

Hairs emerging from planets have both “roots,” the densest concentration of dark matter particles in the hair, and “tips,” where the hair ends. When particles of a dark matter stream pass through Earth’s core, they focus at the “root” of a hair, where the density of the particles is about a billion times more than average. The root of such a hair should be around 600,000 miles (1 million kilometers) away from the surface, or twice as far as the moon. The stream particles that graze Earth’s surface will form the tip of the hair, about twice as far from Earth as the hair’s root.

“If we could pinpoint the location of the root of these hairs, we could potentially send a probe there and get a bonanza of data about dark matter,” Prézeau said.

A stream passing through Jupiter’s core would produce even denser roots: almost 1 trillion times denser than the original stream, according to Prézeau’s simulations.

“Dark matter has eluded all attempts at direct detection for over 30 years. The roots of dark matter hairs would be an attractive place to look, given how dense they are thought to be,” said Charles Lawrence, chief scientist for JPL’s astronomy, physics and technology directorate.

Another fascinating finding from these computer simulations is that the changes in density found inside our planet – from the inner core, to the outer core, to the mantle to the crust – would be reflected in the hairs. The hairs would have “kinks” in them that correspond to the transitions between the different layers of Earth.

Theoretically, if it were possible to obtain this information, scientists could use hairs of cold dark matter to map out the layers of any planetary body, and even infer the depths of oceans on icy moons.

Further study is needed to support these findings and unlock the mysteries of the nature of dark matter.

Is a Warp Drive possible

My son pointed me to this article at dailygalaxy.com about the latest thoughts of researchers about the possiblity of Faster then Light Travel space flight. True space flight will require FLT for several reasons, the main one being Space is a Very very large place. Rocket propulsion just won’t do. Too expensive, too slow, too dangerous.  Only Electro-motive-Force can be the long term solution. An EMF drive can also result in a warp bubble in the stuff of space or Aether that can continually be accelerated as it is not a part of Normal Space.

“Routine travel among the stars is impossible without new discoveries regarding the fabric of space and time, or capability to manipulate it for our needs,” says Neil deGrasse Tyson, the “Cosmos famous” astrophysicist at the American Museum of Natural History, said “By my read, the idea of a functioning warp drive remains far-fetched, but the real take-away is that people are thinking about it — reminding us all that the urge to explore continues to run deep in our species.”

There have been hints in recent news that NASA may be on the path to discovering warp bubbles that could make the local universe accessible for human exploration. NASA scientists may be close announcing they may have broken the speed of light. According to state-of-the art theory, a warp drive could cut the travel time between stars from tens of thousands of years to weeks or months.The catalyst for the trending warp-drive excitement is the Electromagnetic Drive or EM Drive, a thruster that was engineered to steer rockets which eliminates the use of a propellant originally intended for moon missions, Mars missions and low-Earth orbit (LEO) operations.

The experiment that led to the possibility of faster than light interstellar travel took place in the vacuum of space. According to posts on NASASpaceFlight.com, a website devoted to the engineering side of space news, when lasers were fired through the EmDrive’s resonance chamber, some of the beams appeared to travel faster than the speed of light. If that’s true, it would mean that the EmDrive is producing a warp field or bubble. 

But “How?” If the laser beams are moving faster than the speed of light, then it would indicate that they are creating some sort of warp field, or bubble in the space-time foam, which in turn produces the thrust that could, in theory, power a spaceship bound for the center of the Milky Way or one of its dwarf galaxy satellites.

The bubble would contract space-time in front of the ship, flow over the ship, then expand back to normality behind it. It’s inaccurate to describe the spaceship as moving faster than the speed of light, but rather space-time is moving around the ship faster than the speed of light.

Harold G. White, a physicist and advanced propulsion engineer at NASA and other NASA engineers are trying to determine whether faster-than-light travel — warp drive — might someday be possible. The team has attempting to slightly warp the trajectory of a photon, changing the distance it travels in a certain area, and then observing the change with a device called an interferometer.

“Space has been expanding since the Big Bang 13.7 billion years ago,” said Dr. White, 43, who runs the research project told the New York Times. “And we know that when you look at some of the cosmology models, there were early periods of the universe where there was explosive inflation, where two points would’ve went receding away from each other at very rapid speeds. Nature can do it,” he added. “So the question is, can we do it?”

In 1994, a Mexican physicist, Miguel Alcubierre, theorized that faster-than-light speeds were possible in a way that did not contradict Einstein by harnessing the expansion and contraction of space itself. Under Dr. Alcubierre’s hypothesis, a ship still couldn’t exceed light speed in a local region of space. But a theoretical propulsion system he sketched out manipulated space-time by generating a so-called “warp bubble” that would expand space on one side of a spacecraft and contract it on another.

An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship can ride the wave to accelerate to high speeds and time travel. The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional “warp drive” from Star Trek, which can travel “faster than light/”

Alcubierre-warp-drive-manifold“In this way, the spaceship will be pushed away from the Earth and pulled towards a distant star by space-time itself,” Dr. Alcubierre wrote. Dr. White, the NYT reports, has likened it to stepping onto a moving walkway matter leads to questions about whether it is actually possible at an airport.

Alcubierre’s theory, however, depended on large amounts of a little understood or observed type of “exotic matter” that violates typical physical laws.

In general relativity, one often first specifies a plausible distribution of matter and energy, and then finds the geometry of the spacetime associated with it; but it is also possible to run the Einstein field equations in the other direction, first specifying a metric and then finding the energy-momentum tensor associated with it, and this is what Alcubierre did in building his metric. This practice means that the solution can violate various energy conditions and require exotic matter. The need for exotic to find a way to distribute the matter in an initial spacetime which lacks a “warp bubble” in such a way that the bubble will be created at a later time.

Yet another problem according to Serguei Krasnikov is that it would be impossible to generate the bubble without being able to force the exotic matter to move at locally FTL speeds, which would require the existence of tachyons. Some methods have been suggested which would avoid the problem of tachyonic motion, but would probably generate a naked singularity at the front of the bubble.

Dr. White believes that advances he and others have made render warp speed less implausible. Among other things, he has redesigned the theoretical warp-traveling spacecraft — and in particular a ring around it that is key to its propulsion system — in a way that he believes will greatly reduce the energy requirements. But ”We’re not bolting this to a spacecraft,” he said of the technology.

Richard Obousy, a physicist who is president of Icarus Interstellar, a nonprofit group composed of volunteers collaborating on starship design, said “it is not airy-fairy, pie in the sky. We tend to overestimate what we can do on short time scales, but I think we massively underestimate what we can do on longer time scales.”

Dr. White likened his experiments to the early stages of the WW 11 Manhattan Project, which were aimed at creating a very small nuclear reaction merely as proof that it could be done.

Still, one of the most dubious is Dr. Alcubierre himself. He listed a number of concerns, starting with the vast amounts of exotic matter that would be needed. “The warp drive on this ground alone is impossible,” he said. “At speeds larger than the speed of light, the front of the warp bubble cannot be reached by any signal from within the ship,” he said. “This does not just mean we can’t turn it off; it is much worse. It means we can’t even turn it on in the first place.”

RIVERSIDE, Calif. – Graphene, a one-atom thick sheet of carbon atoms arranged in a hexagonal lattice, has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in graphene by doping it with magnetic impurities, but this doping tends to disrupt graphene’s electronic properties.
Now a team of physicists at the University of California, Riverside has found an ingenious way to induce magnetism in graphene while also preserving graphene’s electronic properties. They have accomplished this by bringing a graphene sheet very close to a magnetic insulator – an electrical insulator with magnetic properties.
“This is the first time that graphene has been made magnetic this way,” said Jing Shi, a professor of physics and astronomy, whose lab led the research. “The magnetic graphene acquires new electronic properties so that new quantum phenomena can arise. These properties can lead to new electronic devices that are more robust and multi-functional.”
The finding has the potential to increase graphene’s use in computers, as in computer chips that use electronic spin to store data.
Study results appeared online earlier this month in Physical Review Letters.
The magnetic insulator Shi and his team used was yttrium iron garnet grown by laser molecular beam epitaxy in his lab. The researchers placed a single-layer graphene sheet on an atomically smooth layer of yttrium iron garnet. They found that yttrium iron garnet magnetized the graphene sheet. In other words, graphene simply borrows the magnetic properties from yttrium iron garnet.
Magnetic substances like iron tend to interfere with graphene’s electrical conduction. The researchers avoided those substances and chose yttrium iron garnet because they knew it worked as an electric insulator, which meant that it would not disrupt graphene’s electrical transport properties. By not doping the graphene sheet but simply placing it on the layer of yttrium iron garnet, they ensured that graphene’s excellent electrical transport properties remained unchanged.
In their experiments, Shi and his team exposed the graphene to an external magnetic field.  They found that graphene’s Hall voltage – a voltage in the perpendicular direction to the current flow – depended linearly on the magnetization of yttrium iron garnet (a phenomenon known as the anomalous Hall effect, seen in magnetic materials like iron and cobalt).  This confirmed that their graphene sheet had turned magnetic.
Shi was joined in the study by UC Riverside’s Zhiyong Wang (first author of the research paper), Chi Tang, Raymond Sachs and Yafis Barlas.
Grants to Shi and his team members from the U.S. Department of Energy and the National Science Foundation supported the research.

Search for Gravitational Waves

 

Science Powerhouses Unite to Help Search for Gravitational Waves

Scientists since Albert Einstein have believed that when major galactic events like supernova explosions or black hole mergers occur in the universe, they leave a trace. That trace, it is believed, takes the form of gravitational waves, ripples in the curvature of space-time that propagate as a wave, travelling outward from the source.

For over a decade, scientists and engineers have engaged in one of the most ambitious research efforts ever undertaken: to design, build and operate the Laser Interferometer Gravitational-wave Observatory (LIGO) to identify signs of gravitational waves.

From 2002 to 2010, hundreds of scientists worked together to bring the experiment to life. It required two gravitational wave observatories, 1,865 miles apart, working in unison: the LIGO Livingston Observatory in Livingston, Louisiana, and the LIGO Hanford Observatory, located near Richland, Washington. LIGO was developed and is managed by Caltech and MIT, and is funded by the National Science Foundation (NSF).
