Antigravity propulsion with Paul LaViolette

Paul LaViolette discussed the physics behind anti-gravity propulsion technology and showed how it is not only possible, but is currently being used in secret projects. "We're sort of being held in a 'technology cage,' on purpose, for fear of change," he said. He detailed some of the early experiments conducted by Nikola Tesla and T. Townsend Brown, who both used electricity to affect gravity. LaViolette noted that, in the mid-1950's, numerous aviation companies were not only attempting to develop anti-gravity technology but were quite open and enthusiastic about it -- until 1959. "Suddenly it was like a blackout in the media," he observed.

Physicist Discovers How to Teleport Energy

· First, they teleported photons, then atoms and ions. Now one physicist has worked out how to do it with energy, a technique that has profound implications for the future of physics.
http://www.technologyreview.com/blog/arxiv/24759/
Quantum Energy Teleportation - www.technologyreview.com
In 1993, Charlie Bennett at IBM's Watson Research Center in New York State and a few pals showed how to transmit quantum information from one point in space to another without traversing the intervening space.
The technique relies on the strange quantum phenomenon called entanglement, in which two particles share the same existence. This deep connection means that a measurement on one particle immediately influences the other, even though they are light-years apart. Bennett and company worked out how to exploit this to send information. (The influence between the particles may be immediate, but the process does not violate relativity because some informatiom has to be sent classically at the speed of light.) They called the technique teleportation.
[...]
But Masahiro Hotta at Tohoku University in Japan has come up with a much more exotic idea. Why not use the same quantum principles to teleport energy?
[...]
All this is possible because there are always quantum fluctuations in the energy of any particle. The teleportation process allows you to inject quantum energy at one point in the universe and then exploit quantum energy fluctuations to extract it from another point. Of course, the energy of the system as whole is unchanged.
[...]
There is a growing sense that the properties of the universe are best described not by the laws that govern matter but by the laws that govern information. This appears to be true for the quantum world, is certainly true for special relativity, and is currently being explored for general relativity. Having a way to handle energy on the same footing may help to draw these diverse strands together.

Golden Ratio Discovered in Quantum World

· Hidden Symmetry Observed for the First Time in Solid State Matter.
http://www.eurekalert.org/pub_releases/2010-01/haog-grd010510.php
Golden Ratio Discovered in Quantum World - www.eurekalert.org
Researchers from the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), in cooperation with colleagues from Oxford and Bristol Universities, as well as the Rutherford Appleton Laboratory, UK, have for the first time observed a nanoscale symmetry hidden in solid state matter. They have measured the signatures of a symmetry showing the same attributes as the golden ratio famous from art and architecture. The research team is publishing these findings in Science on the 8th January.
On the atomic scale particles do not behave as we know it in the macro-atomic world. New properties emerge which are the result of an effect known as the Heisenberg's Uncertainty Principle. In order to study these nanoscale quantum effects the researchers have focused on the magnetic material cobalt niobate. It consists of linked magnetic atoms, which form chains just like a very thin bar magnet, but only one atom wide and are a useful model for describing ferromagnetism on the nanoscale in solid state matter.
When applying a magnetic field at right angles to an aligned spin the magnetic chain will transform into a new state called quantum critical, which can be thought of as a quantum version of a fractal pattern. Prof. Alan Tennant, the leader of the Berlin group, explains "The system reaches a quantum uncertain – or a Schrödinger cat state. This is what we did in our experiments with cobalt niobate. We have tuned the system exactly in order to turn it quantum critical."
By tuning the system and artificially introducing more quantum uncertainty the researchers observed that the chain of atoms acts like a nanoscale guitar string. Dr. Radu Coldea from Oxford University, who is the principal author of the paper and drove the international project from its inception a decade ago until the present, explains: "Here the tension comes from the interaction between spins causing them to magnetically resonate. For these interactions we found a series (scale) of resonant notes: The first two notes show a perfect relationship with each other. Their frequencies (pitch) are in the ratio of 1.618…, which is the golden ratio famous from art and architecture." Radu Coldea is convinced that this is no coincidence. "It reflects a beautiful property of the quantum system – a hidden symmetry. Actually quite a special one called E8 by mathematicians, and this is its first observation in a material", he explains.
The observed resonant states in cobalt niobate are a dramatic laboratory illustration of the way in which mathematical theories developed for particle physics may find application in nanoscale science and ultimately in future technology. Prof. Tennant remarks on the perfect harmony found in quantum uncertainty instead of disorder. "Such discoveries are leading physicists to speculate that the quantum, atomic scale world may have its own underlying order. Similar surprises may await researchers in other materials in the quantum critical state."

[And, the scientific document (for sale...): "Quantum Criticality in an Ising Chain: Experimental Evidence for Emergent E8 Symmetry". An excerpt...]
"Quantum phase transitions take place between distinct phases of matter at zero temperature. Near the transition point, exotic quantum symmetries can emerge that govern the excitation spectrum of the system. A symmetry described by the E8 Lie group with a spectrum of eight particles was long predicted to appear near the critical point of an Ising chain. We realize this system experimentally by using strong transverse magnetic fields to tune the quasi–one-dimensional Ising ferromagnet CoNb2O6 (cobalt niobate) through its critical point. Spin excitations are observed to change character from pairs of kinks in the ordered phase to spin-flips in the paramagnetic phase. Just below the critical field, the spin dynamics shows a fine structure with two sharp modes at low energies, in a ratio that approaches the golden mean predicted for the first two meson particles of the E8 spectrum. Our results demonstrate the power of symmetry to describe complex quantum behaviors."

Evidence of macroscopic quantum tunneling detected in nanowires

http://news.illinois.edu/news/09/0527tunneling.html
Mitrabhanu Sahu, Alexey Bezryadin, and Paul Goldbart - news.illinois.edu
A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to “tunnel” as a pack from a state with a higher electrical current to one with a notably lower current, providing more evidence of the phenomenon of macroscopic quantum tunneling.
Physics professors Alexey Bezryadin and Paul Goldbart led the team, with graduate student Mitrabhanu Sahu performing the bulk of the measurements. Their research was published on the Web site of the journal Nature Physics on May 17.
Quantum tunneling is the capability of a particle to inhabit regions of space that would normally be off-limits according to classical mechanics. This research observes a process called a quantum phase slip, whereby packs of roughly 100,000 electrons tunnel together from higher electrical current states to lower ones. The energy locked in the motion of the electrons as they phase slip is dissipated as heat, causing the nanowires to switch from a superconducting state to a more highly resistive one.
It’s through this switching of states that allows the tunneling of the phase slip to be observed, the researchers say.
Goldbart, who is also a researcher at the university’s Frederick Seitz Materials Research Laboratory, describes a quantum phase slip as a phenomenon that allows the spatially extended structure of superconductivity “to undergo a kind of quantum mechanical rip or tear, one where the entire extended behavior of the superconductivity tunnels its way through a classically forbidden set of configurations.”
“Semiconductors, insulators and metals all hinge upon the ability of particles to make it through classically forbidden regions, despite apparently having negative kinetic energy there, as quantum physics allows,” Goldbart said.
In Newton’s world, according to Goldbart, particles would be reflected from such regions.
Although quantum mechanics governs the realm of atoms and molecules and smaller, quantum phenomena sometimes “leak up” to macroscopic scales, he said.
“Observing switching events in superconducting nanowires at high-bias currents provides strong evidence for quantum phase slips. Our experiments provide further evidence that the laws of quantum mechanics continue to govern large systems, composed of many thousands of electrons, acting as a single entity.”

Scientists confirm superheavy element 114

· Berkeley, CA - 09.29.2009
http://www.upi.com/Science_News/2009/09/29/Scientists-confirm-superheavy-element-114/UPI-80501254234045/
www.upi.com - Element 114
U.S. scientists say they have confirmed the production of the superheavy element 114, 10 years after a Russian group first claimed to have made it.
The researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, led by University of California-Berkeley Professor Heino Nitsche and and Berekely Lab senior staff scientist Ken Gregorich, independently confirmed the production of the new element, which was first published by the Dubna Gas Filled Recoil Separator group.
[...]
"This proves that the most interesting superheavy elements can in fact be made in the laboratory."

"People have been dreaming of superheavy elements since the 1960s, but it's unusual for important results like the Dubna group's claim to have produced 114 to go unconfirmed for so long. Scientists were beginning to wonder if superheavy elements were real."

Earth’s Magnetic Field is Not Produced Inside the Planet

http://sites.google.com/site/earthsmagneticfield/

by Dennis Brooks, 10.21.2009
The New Theory: Earth’s magnetic field is not produced by an internal dynamo within the planet. The magnetic field and the planet are separate parts of a complex dynamo system surrounding the planet. The system includes the planet, the magnetic field, radiation belts, and ring current. The same is true of the other planets. Saturn, Jupiter, Neptune, and Uranus are visible components of otherwise invisible planetary dynamo systems, which are all housed within a magnetosphere. According to this new theory, there is no internal dynamo within the planet. Planet Earth does not have a unique way of producing it’s magnetic field. Nor do the other planets. Each magnetic field of each planet is produced in exactly the same way, by its planetary dynamo system.
A planetary dynamo system is composed of a complex network of components including a magnetosphere, a planet, a magnetic field, radiation belts, ring current, and charged particles from the solar wind. The planet is the central component of the system and it’s movements also play an important part in operating the dynamo and generating current. Planets that rotate fast usually have a stronger magnetic field, and planets that rotate slowly, have weaker magnetic fields. The dynamo system captures charged particles from the sun and uses them as fuel. The particles are moved into different areas of the system to perform different functions in fueling the dynamo. It’s the planet’s movement that helps to produce the system’s current.
The magnetic field is a separate component of the dynamo and is generated by the system’s ring current. Ring current is an impressive component of the dynamo system. It is made up entirely of charged particles and provides the energy necessary for producing the magnetic field. The magnetic field captures the charged particles from the solar wind, and brings them into the dynamo for fuel. All the components and forces work together to make up the planetary dynamo. Some researchers believe that a similar dynamo system exists within the planet and this internal dynamo system generates the current that produces the magnetic field.

Relativistic Relativity

· A hypothetical study into the relativistic symmetry between celestial and quantum objects.
http://www.gpofr.com/documents/realitivistic%20relativity.pdf
http://athena.nucleares.unam.mx/home/images/blackhole.jpg
by Robert L. DeMelo

Abstract

This paper examines the hypothetical possibility of relativistic symmetry between the celestial and quantum realms based solely on a scale difference between the two systems and the concept of space-time density derived from Einstein’s curvature of space. The exploratory analysis presented in this paper derives two surprising mathematical coincidences including a new scale relativity mass equation which calculates Jupiter's relativistic mass (1.898x1027 kilograms) to the numerical value of an electron charge (1.6x10-19 coulombs) exactly. This simple equation strongly suggests a direct mathematical relation between charge and mass, gives credence to the likelihood that the Universe is fractal in nature and that dimension changes with scale. Essentially this equation possibly unites our perception of mass at the celestial scale to that of charge at quantum scale which has enormous implications for all of physics.
Basically, I calculated a value called "S". It's a scale constant between quantum and celestial systems. My hypothesis in the theory are that atoms are simply star system in a different space-time density (or velocity frame of reference). It's more complex then this one sentence. In this theoretical model, gas giants are electrons. From the value of S I've been able to derive Jupiter's mass to the numerical value of an electron charge which is a fundamental value in physics. Basically, the "concept" of scale is unchanging between quantum and celestial objects, or what we call invariant. This concept isn't new, but my exact hypothesis is and so is the value of S.
There are a few implications. First, it unites Newton's and Einstein's work with modern quantum theory. To me this is big. Second, and perhaps the most practically useful, it gives rise to some very interesting technology. In this theoretical model, the speed of light is not a limit, but is still a constant. Basically, you can go faster than the speed of light not only for travel but also for communication.

In Search of Antimatter Galaxies

http://www.scienzagiovane.unibo.it/english/antimatter/images/idrogeno-anti.gif
NASA's space shuttle program is winding down. With only about half a dozen more flights, shuttle crews will put the finishing touches on the International Space Station (ISS), bringing to an end twelve years of unprecedented orbital construction. The icon and workhorse of the American space program will have finished its Great Task.
[...]
An act of Congress in 2008 added another flight to the schedule near the end of the program. Currently scheduled for 2010, this extra flight of the shuttle is going to launch a hunt for antimatter galaxies.
The device that does the actual hunting is called the Alpha Magnetic Spectrometer--or AMS for short. It's a $1.5 billion cosmic ray detector that the shuttle will deliver to the ISS.
[...]
Antimatter galaxies, dark matter, strangelets--these are just the phenomena that scientists already know about. If history is any guide, the most exciting discoveries will be things that nobody has ever imagined. Just as radio telescopes and infrared telescopes once revealed cosmic phenomena that had been invisible to traditional optical telescopes, AMS will open up another facet of the cosmos for exploration.
[...]
Another mystery that AMS will help solve is the nature of dark matter. Scientists know that the vast majority of the universe is actually made of unseen dark matter rather than ordinary matter. They just don't know what dark matter is. A leading theory is that dark matter is made of a particle called the neutralino. Collisions between neutralinos should produce a large number of high-energy positrons, so AMS could prove whether dark matter is made of neutralinos by looking for this excess of energetic positrons.

Beyond space and time: Fractals, hyperspace and more

http://www.newscientist.com/special/beyond-space-and-time
http://www.imageboo.com/files/0mc83557spz87lqdizbm.jpg
We don't have any trouble coping with three dimensions – or four at a pinch. The 3D world of solid objects and limitless space is something we accept with scarcely a second thought. Time, the fourth dimension, gets a little trickier. But it's when we start to explore worlds that embody more – or indeed fewer – dimensions that things get really tough.
These exotic worlds might be daunting, but they matter. String theory, our best guess yet at a theory of everything, doesn't seem to work with fewer than 10 dimensions. Some strange and useful properties of solids, such as superconductivity, are best explained using theories in two, one or even no dimensions at all.
Prepare your mind for boggling as we explore the how, why and where of dimensions. [Click on the images...]

so a 0D space must amount to nothing at all –mustn't it?

Physics in one dimension is too simple to be satisfying,
and three dimensions are complicated and messy.
Two-dimensional "flatland" is just right.

Flatland and multi-dimensional hyperspace make fine playgrounds for
the mind, but our bodies seem stuck in a space of three dimensions.

Time, we are told, is also a dimension.
So how come it is so different to the others?

they always seem to mean the space kind.
Why can't we have more time?

New Class of Black Holes Discovered

http://www.wired.com/wiredscience/2009/07/mediumblackhole/
http://www.wired.com/images_blogs/wiredscience/2009/07/black-hole3.jpg
Only two sizes of black holes have ever been spotted: small and super-massive. Scientists have long speculated that an intermediate version must exist, but they’ve never been able to find one until now.
Astrophysicists identified what appears to be the first-ever medium-sized black hole, pictured in an artist’s rendition above, with a mass at least 500 times that of our Sun. Researchers from the Centre d’Etude Spatiale des Rayonnements in France detected the middling hole in a galaxy about 290 million light-years from Earth.
The discovery may shed some light on the origins of super-sized black holes like the one at the center of our own galaxy. These astral heavyweights top out at several million to several billion times the mass of the Sun, but their origin remains a mystery.
[...]
The new discovery is the most convincing evidence to date that medium black holes exist. Using the European Space Agency’s XMM-Newton X-ray space telescope, the researchers identified a radiation source that gives off X-rays 260 million times brighter than the radiation of the Sun.
Called “Hyper-Luminous X-ray Source 1,” the structure sits on the edge of galaxy ESO 243-49. Because of the source’s physical characteristics and the pattern of its radiation, the researchers conclude it must be a black hole more than 500 times the mass of the sun: not too big, not too small, and the first of its kind.

Australian scientists have developed a new method for transmitting data with light that may lead to super-fast quantum computers and teleportation technology.
The research team from the Australian National University developed a new approach to generating quantum entanglement in beams of light using only two parts.
Quantum entanglement is a process in which two objects are linked together in such a way that any changes to the properties of one can be measured from the other regardless of the distance between them.
This process of linking particles has existed for a few years but team leader Dr Jiri Janousek says this new method allows it to be achieved in a much simpler way.

Radical new theory suggests Earth's magnetism may be linked to movement of ocean currents

http://www.dailymail.co.uk/sciencetech/article-1192980/Radical-new-theory-Earths-magnetic-field-revolutionise-geophysics.html
http://i.dailymail.co.uk/i/pix/2009/06/14/article-1192980-055755BB000005DC-106_468x470.jpg
New research suggests that Earth’s magnetic field could be produced by ocean currents rather than molten metals swirling around its core as was previously thought.
The controversial new claims, published this week, suggest that the movements of volumes of salt water around the world have been seriously underestimated by scientists as a source of magnetism.
The research could revolutionise geophysics, the study of the Earth’s physical properties and behaviour, in which the idea that magnetism originates in a molten core is a central tenet.
“Everyone accepted this, but in reality there has never been any proof,” said Gregory Ryskin, associate professor of chemical and biological engineering at Northwestern University in Illinois.
“It is just an idea we have accepted for a long time without questioning it enough.”
His research suggests that Earth’s magnetism is instead linked to ocean movements.
The salt in seawater allows it to conduct electricity, meaning it generates electrical and magnetic fields as it moves.
The findings, published by Britain’s Institute of Physics’s New Journal of Physics, will no doubt cause a fierce scientific debate.
Existing theories explain Earth’s magnetism by suggesting that the centre of the planet comprises a white-hot solid iron ball about 1,500 miles in diameter, surrounded by an outer shell of liquid metal a further 1,400 miles thick.

Sprite: Spirits of Another Sort

·Thunderstorms Generate Elusive and Mysterious Sprites.
http://science.nasa.gov/newhome/headlines/essd10jun99_1.htm
[z20090610_214256_GGRI__020s.jpg]
For centuries, man has been transfixed by the spectacular lightning displays of thunderstorms. But after all those years of gazing at the sky, we never realized there was an equally amazing light show going on above the clouds.
In our own century, pilots reported seeing strange lights in the sky above thunderstorms. Low-light cameras on board airplanes and the Space Shuttle have recently made possible the documentation of sprites - quick red flashes of light that appear above storm clouds.
[M20090610_221312_GGRI_P_deint1.jpg]
Dr. Dave Sentman of the University of Alaska, Fairbanks is one among a small group of researchers who have been studying these mysterious bursts of colored light. Although no one is sure what sprites really are or what causes them, these scientists have learned that sprites contain a great deal of energy.
[M20090610_232320_GGRI_P_deint1.jpg]
"Although we're not yet certain, we suspect that the energies from sprites may be sufficient to drive some novel chemical reactions," said Sentman. "The region of the atmosphere where sprites appear typically doesn't contain a lot of energy, so the energy introduced from a sprite could do some really interesting things."

A New Theory That Unifies The Forces of Nature

http://www.mondovista.com/unified.field.html
By
Prof. A. Zielinski*
http://d21c.com/sookietex/nano_aether.jpg
The earth is expanding. All celestial bodies have magnetic fields that are circular or polar dependent on spin. The magnetic north- and south poles are produced by the earthís spin. The magnetic poles are moving but are on the same spot at the same hour. Every galaxy has more or less a "black hole" that is not a hole at all. The universe is not expanding, there was never a "BIG BANG". Electric power can be generated from eather.

Abstract

A new exciting discovery of the existence and behavior of aether leads to a new concept of the essence of aether, that is able to explain why the famous Michelson-Morley aether experiment of 1887 failed, explain and unify the forces of nature, explain why quantum theory works and even explain where the universe comes from, and last but not least, shows the gateway to the new source of energy of the future.
