Lockheed Executive Blows Lid Off of Secret Government Space Travel (Quantum Entanglement)

Posted by in categories: government, particle physics, quantum physics, space travel

Another (more in depth) on Lockheed’s efforts on Space Travel leveraging Quantum Entanglement.

It’s called quantum entanglement, it’s extremely fascinating and counter to what we believe to be the known scientific laws of the universe, so much so that Einstein himself could not wrap his head around it. Although it’s called “quantum entanglement,” though Einstein referred to it as “spooky action at a distance.”

Quantum Mechanics Revisited: Physicists Propose New Structure of Time

Posted by in categories: information science, particle physics, quantum physics

Read a little further into the paper, and things get really weird. If the equations of quantum mechanics must be altered in accordance with the new research, then it will give rise to a new and very curious definition of time.

Time is, essentially, a “crystal”—a highly organized lattice of discrete “particles,” or regularly repeating segments.

Cold plasma will heal non-healing wounds

Posted by in categories: biotech/medical, particle physics

Russian scientists have found that treating cells with cold plasma leads to their regeneration and rejuvenation. This result can be used to develop a plasma therapy program for patients with non-healing wounds. The paper has been published in the Journal of Physics D: Applied Physics.

Non-healing wounds make it more difficult to provide effective treatment to patients and are therefore a serious problem faced by doctors. These wounds can be caused by damage to blood vessels in the case of diabetes, failure of the immune system resulting from an HIV infection or cancers, or slow cell division in elderly people. Treatment of non-healing wounds by conventional methods is very difficult, and in some cases impossible.

Cold atmospheric-pressure plasma refers to a partially ionized gas—the proportion of charged particles in the gas is close to 1 percent, with a temperature below 100,000 K. Its application in biology and medicine is possible through the advent of plasma sources generating jets at 30–40?°C.

Synopsis: Spotting Dark Matter with Supermaterials

Posted by in categories: cosmology, particle physics

Superconducting aluminum or superfluid helium could be used to detect superlight dark matter particles.

Dark matter searches repeatedly draw a blank. One possible reason for the failure may be dark matter’s mass: Despite increased sensitivity, current detectors cannot spot the particles that make up this elusive matter if the particles are extremely light. Now Kathryn Zurek from the Lawrence Berkeley National Laboratory, California, and colleagues have come up with two new ideas for making detectors that should be capable of spotting such superlight particles.

In broad strokes, dark matter detectors are designed to operate as follows: Incoming dark matter particles strike the detector, gently nudging nearby atomic nuclei or electrons in the material from which the detector is made. These rare nudges generate small amounts of energy in the form of light or heat, which the detector registers. But the ability to detect particles of a certain mass depends on the properties of the detector material, such as the mass of its nuclei. Current detectors, made from semiconducting materials or liquid xenon, are sensitive only to particles heavier than about 10 million electronvolts.

New Laser Provides Ultra-Precise Tool for Scientists Probing the Secrets of the Universe

Posted by in categories: particle physics, quantum physics, space

WASHINGTON — Researchers have developed a new laser that makes it possible to measure electron transition energies in small atoms and molecules with unprecedented precision. The instrument will help scientists test one of the bedrock theories of modern physics to new limits, and may help resolve an unexplained discrepancy in measurements of the size of the proton.

The team will present their work during the Frontiers in Optics (FiO) / Laser Science (LS) conference in Rochester, New York, USA on 17 −21 October 2016.

“Our target is the best tested theory there is: quantum electrodynamics,” said Kjeld Eikema, a physicist at Vrije University, The Netherlands, who led the team that built the laser. Quantum electrodynamics, or QED, was developed in the 1940s to make sense of small unexplained deviations in the measured structure of atomic hydrogen. The theory describes how light and matter interact, including the effect of ghostly ‘virtual particles.’ Its predictions have been rigorously tested and are remarkably accurate, but like extremely dedicated quality control officers, physicists keep ordering new tests, hoping to find new insights lurking in the experimentally hard-to-reach regions where the theory may yet break down.

Benchtop Black Holes Help Physicists Glimpse the Quantum Universe

Posted by in categories: cosmology, particle physics, quantum physics

A black hole is a physicist’s playground: A place where some of the most bizarre and fundamental concepts in physics can be observed and tested. However, there is currently no way to directly observe black holes in action; these bodies of matter don’t emit the sort of radiation, like light or X-rays, that telescopes are equipped to detect. Fortunately, physicists have figured out ways to imitate the conditions of a black hole in the lab—and in creating analogues of black holes, they are beginning to unravel some the most fascinating puzzles in physics.

Jeff Steinhauer, a researcher in the Physics Department of Technion-Israel Institute of Technology, recently caught the attention of the physics community when he announced that he had used an analogue black hole to confirm Stephen Hawking’s 1974 theory that black holes emit electromagnetic radiation, known as Hawking radiation. Hawking predicted that this radiation would be caused by the spontaneous creation of a particle-antiparticle pair at the event horizon, the point at the edge of a black hole beyond which nothing—not even light—can escape. Under the terms of Hawking’s theory, as one of the particles crosses the event horizon and is captured by the black hole, the other would be ejected into space. Steinhauer’s experiment was the first to exhibit the sort of spontaneous fluctuations that support Hawking’s calculations.

Physicists have cautioned that this experiment still doesn’t confirm the existence of Hawking radiation in astronomical black holes, as Steinhauer’s black hole isn’t exactly the same as one we might observe in space. It’s not yet physically possible to create the intense gravitational fields that form black holes. Instead, the analogue imitates a black hole’s ability to absorb light waves by using sound.

Whispering gallery-mode biosensors are worth shouting about

Posted by in categories: biotech/medical, particle physics

In early 2016 University Professor of Applied Physics Stephen Arnold earned a patent for his system for finding the size of one or more individual particles (such as nanoparticles) in real time using a microsphere’s whispering gallery modes.

Arnold and his team at Tandon’s MicroParticle PhotoPhysics Laboratory for BioPhotonics (MP3L) had generated excitement throughout the in 2012, when they created an ultra-sensitive biosensor capable of identifying the smallest single virus particles in solution.

Their technique was a major advance in a series of experiments to devise a diagnostic method sensitive enough to detect and a single virus particle in a doctor’s office or field clinic, without the need for special assay preparations or conditions. Normally, such assessment required the virus to be measured in the vacuum environment of an electron microscope, which added time, complexity and considerable cost.

Quantum Entanglement & Space Travel

Posted by in categories: particle physics, quantum physics, space travel

Now, if we could just get the US to launch our own Quantum Satellite in space.

Recent research has taken quantum entanglement out of the theoretical realm of physics, and placed into the one of verified phenomena. An experiment devised by the Griffith University’s Centre for Quantum Dynamics, led by Professor Howard Wiseman and his team of researchers at the university of Tokyo, recently published a paper in the journal Nature Communications confirming what Einstein did not believe to be real: the non-local collapse of a particle’s wave function. (source)(source), and this is just one example of many.

Will Quantum Computers Transform The Next Century?

Posted by in categories: computing, particle physics, quantum physics

Hmmmm; I suggest that “Kate” needs to follow up with the research teams at the University of Sydney, MIT, ORNL, and University of China who have already proven and shared insights and techniques to stabilize QC, make it scalable (as we are already seeing Google leverage), and trace particles throughout entanglement. I really do not like ready articles that misleads the public because the author was lazy in not doing their own research and homework on their topics.

Today I’d like to speak about quantum computers and to share my ideas of their purpose in the nearest future. As you know, applying the laws of quantum mechanics it’s actually possible to create a new type of computing machine, enabling to solve some of the issues, being currently unable to resolve even upon the use of the most powerful machines. As a result, the speed of major complex computations will significantly increase, for instance, the messages sent via quantum coupling lines will be impossible to capture or to copy. Sounds quite fantastic, isn’t it? Furthermore, today we already have working prototypes of future quantum computers. So, let’s consider this topic more precisely.
