NASA has tentative plans to take an EM Drive out for a spin in Earth's orbit by 2018. Dr Chen said China has already done so. He didn’t give more details but it seems likely the Middle Kingdom version of the EM Drive is being tested on the country's Tiangong-2 space lab.
China is trying out different shapes for the reaction chamber of the drive to see which generates the most thrust. It's clear that the country is taking the EM Drive seriously and wants to get one operational as soon as possible.
"This technology is currently in the latter stages of the proof-of-principle phase, with the goal of making the technology available in satellite engineering as quickly as possible," said Li Feng, chief architect of the China National Space Technology Institute's communications satellite division, at the press conference.
Dr Dragan Hajdukovic at Cern, who has developed a theory that gravitational polarity does exist. He says: "So far, we believe that gravity's only a force of attraction. It may be that gravity can also be a force of repulsion but not between matter and matter but between matter and anti-matter."
Mike,
There was a former high command officer who worked for NATO on some type of anti-gravity system in early 1970s-80 who said they were fifty years ahead. So not all surprised they cracked it decades ago.

It’s nice to see someone else following this subject as maniacally as I do, haha. But you’ve posted way too many topics to address them all in any detail, so let’s focus on the most exciting stuff and we can circle back to the other items if you want to get into them more deeply.Eugene Podkletnov - Wikipedia
This is amazing work, so a brief synopsis is in order.Some theorists are now breaking ranks to offer radical explanations, among them Dr Dragan Hajdukovic at Cern, who has developed a theory that gravitational polarity does exist. He says: "So far, we believe that gravity's only a force of attraction. It may be that gravity can also be a force of repulsion but not between matter and matter but between matter and anti-matter."
I understand why people get excited about the EM Drive when they read the wildly optimistic assessments in the popular science press. But again and again we’ve seen radical claims, often by highly credentialed scientists, go up in smoke upon closer examination. Podkletnov’s work circled the drain when other teams couldn’t reproduce his results. Martin Tajmar thought he detected a related effect in a cryonic tube, but a laser interferometer detected no effect, and soon after Tajmar realized that he had simply detected some vapor swirling around his spinning superconductor. Minuscule forces, like we see with the EM Drive, are notoriously easy to mistake for some exotic new effect. And in every case so far, these extraordinary gravitational field effect claims have turned out to be experimental error.Mysterious Universe notes that the NASA scientists are buzzing about the discovery on the NASA Spaceflight Forums.
Did NASA Just Accidentally Produce A Warp Bubble? EmDrive Could Lead To Warp Drive
Aerospace companies started looking into gravitational propulsion concepts back in the 50s, as you probably know. I wouldn’t be surprised if they’ve worked it out by now. I saw some infrared video footage that Richard Dolan had taken through a telescope, which looks like odd triangular military craft using some kind of field propulsion in the upper atmosphere.Boeing Admitted Testing Anti-Gravity 12 Years Ago | Humans Are Free
The AlienScientist has made some interesting videos, but this one is mostly word salad. YouTube videos are rarely a source of useful new information.

Nope. That paper was from 2012. Yang’s team has subsequently analyzed the precision of the torsion pendulum system they used to measure their earlier results, and they discovered that it was much too unstable to measure the thrust that they thought they had seen. Here’s a quote from the retraction paper that reversed their earlier claims:But the controversy attracted the attention of China's Yang Juan, professor of propulsion theory and engineering of aeronautics and astronautics at the Northwestern Polytechnic University in Xian. Her team set out to explore the EmDrive independently. A 2008 theory paper by Yang and colleagues describes the EmDrive in terms of quantum theory and indicates net thrust is possible. A 2010 follow-up paper calculates a possible thrust of 456 mN from a 1-kw input, and states that the team was getting positive experimental results.
The latest paper, “Net Thrust Measurement of Propellentless Microwave Thruster,” is in the June edition of the journal Acta Physica Sinica published by the Chinese Academy of Sciences. Yang's team used a magnetron as a 2.45 GHz microwave source and produced a measured thrust of up to 720 mN from 2.5 kw of input power. On the surface, this appears to be a peer-reviewed validation of the science.
Nah. That’s like saying that the rapid introduction of the automobile would destroy the global economy because the horse feed suppliers and the stable providers would go out of business all at once. Instead, it sparked an unprecedented explosion of growth with incalculable benefits.I wrote a detailed post here many years back that details how antigrav technology and free or very cheap energy could destroy the global economy if introduced too quickly.
No, this isn’t useful. It appears that Dr. Felber has mistaken a relativistic perceptual effect between reference frames, for a local “antigravity” force."Based on this research, I expect a mission to accelerate a massive payload to a 'good fraction of light speed' will be launched before the end of this century," said Dr. Felber. "These antigravity solutions of Einstein's theory can change our view of our ability to travel to the far reaches of our universe."
A lot of people are reading the phrase “breakaway civilization” too literally – it hasn’t physically broken away, it’s nestled within our own civilization: proximal but separate.And that plays nicely into the breakaway civilization theory s that are part and parcel of this genre.

While I'm not saying its happening, I can see the motivations behind doing so if you had the means.
The Nazi bell narrative for example, again not saying its real or likely, But if it were it would fit with the ideology that drove them and having lost the war here on earth to simply set up their vision of the perfect society elsewhere if they could.
The seeming lemming like attitude to our looming environmental disaster here on earth also fits that narrative. Why bother trying to fix the difficult to fix if its easier to just walk away and start again elsewhere.
I think given the means , motive and opportunity a small select group would happily breakaway.
I'm simply asking the same question I ask about the "hidden bases" that supposedly exist deep underground across the continent.The John Keel idea of a breakaway systems and its interaction with paranormal worlds is not too far fetch to antigravity and parallel worlds . Not ignoring excellent researcher and journalist Graham Hancock work of lost civilisations. Plauisble the evidence of a factory from which this type of mechanism came from most likely is in the Antarctic or Gobekli Tepi underground structures and vaults.

What is the Antikythera Mechanism? How was this ancient 'computer' discovered? of thease lost civilisations. Therefore the antigravity and ridicule from some parts of the science community of the concept doesn't look to outlandish comparing to this discovery over hundred years ago regarding technology developments of the past .
Frank is right about one thing: if we had a material with extremely high nonlinear gravitomagnetic permeability (analogous to the use of iron to amplify a magnetic field), we could probably bring gravitomagnetism into the lab.You and @Thomas R Morrison will probably want to check out this link to American Antigravity and the embedded audio interview with Znidarsic: Frank Znidarsic on Antigravity
Frank is right about one thing: if we had a material with extremely high nonlinear gravitomagnetic permeability (analogous to the use of iron to amplify a magnetic field), we could probably bring gravitomagnetism into the lab.
Unfortunately, that seems to be just about the only thing that Frank is right about. For example, he says that a gravitomagnetic field would let us “bounce” off the atmosphere. No, that’s not right. Gravitomagnetism obeys the same Gaussian field law as magnetism (which in technical terms states that the divergence of the field is zero); so if you set up a gravitomagnetic field that has a direction pointing downward through the center, then the field points up around the outside with the same total magnitude. The net effect in the atmosphere would be to circulate the gas through the center and back around the outside like a smoke ring. There’s no net propulsive application for such a device, but you could use it like a cannon to launch something through the center of the device.
This kind of thing happens all the time – people coming up with wild theories to explain effects that aren’t real, like cold fusion and Podkletnov’s claims. The “Pioneer anomaly” is a good recent example of this: people saw that the Pioneer spacecraft were slowing down more than expected after leaving the solar system. So lots of people, even some qualified physicists, started to propose new theories about gravity to explain the effect. But it turned out to be a simple radiation pressure effect generated by the power supply aboard the craft.
Frank has simply taken an unwarranted leap of faith to assume that cold fusion and Podkletnov’s results are both real, and then taken a plunge well out of his scientific depth to construct a wild theory to explain them both.
But I don’t like to make a post without offering something positive and interesting, so I’ll leave you with this fascinating little morsel that slipped under most people’s radar. In 2002, an MIT physicist named Jack Wisdom realized that an object undergoing a specific series of deformations in shape could use the gravitational field to “swim” away from a gravitating body. It’s a brilliant and astonishingly original concept, which reveals that even after nearly a century we’re still discovering new possibilities within the theory of general relativity:

There is a gravitomagnetic effect like that, but with gravitomagnetism opposite poles repel and like poles attract – the main problem being that the Earth has an absurdly weak gravitomagnetic field (dozens of orders of magnitude weaker than the magnetic field), so there’s virtually nothing to interact with. But that’s not what Frank was saying – he thought that a gravitomagnetic field could interact with the atmosphere itself, to “bounce” an object into space…but it just doesn’t work like that.I had a bit of a problem with the idea that the system works by repulsion, like two of the same poles of a magnet pushing against each other.
I’m not sure what levitation effect you’re talking about here – Podkletnov’s claim of a “repulsor beam” has been experimentally refuted, so there’s no effect to talk about in that case. If anyone detects a repulsion between a spinning superconductor and a nonconductive/nonmagnetic material, then that would be interesting and might point to new physics. But so far, nothing has held up to scrutiny.I wonder if perhaps the assumption that the effect is repulsive is because the disks seem to levitate away from the surface by a repulsive force? If that's the case then we can safely say that the interpretation isn't accurate because that levitation effect is magnetic, not gravitational.
A permanent magnet will float above a superconductor because superconductors are perfectly diamagnetic (and flux pinning provides stabilization), but there’s never been a successful confirmed experimental detection of a “gravitational anomaly” in the lab. Not in the public sector anyway.The gravitational anomaly that has been associated with superconductivity and magnetism is a separate thing altogether.
Haha – yeah it’s a shame that nobody’s handing out teams of research scientists plus a lifetime coffee supply ;I've tried suggesting that instead of rotating the disks physically, that they leave the disk stationary and rotate a magnetic field around it. That could be done electronically with far greater efficiency. I'm an armchair theorist at best on this, but my thinking is that low temperature superconductors, being as close to a zero-point state that anything material can get, might be forced by a resonant EM field into converting the energy to gravitation.
Somebody give me a lab coat, a crazy hairdo, and a team of nerd engineers wearing black rimmed glasses and I'll build it. Oh I'll also need a couple of secretaries and a bottomless Starbucks card.
Not so much, actually – most of the fringe gravitational claims we hear about don’t offer much, if anything at all, in the way of theory. If they did, it would be a lot easier to expose the hoaxes, as well as the honest mistakes, by demonstrating falsifiable numerical predictions based on the mathematics of those theories.Many theories point in all directions.
Nope. I keep trying to explain this but so far only marduk has understood it. I’ll try to be very clear.But if we want to stick with where evidence points, than the artificial gravity (not anti-gravity) that UFOs produce is generated by toroidal dipole gravitomagnetic field, that is a part of general relativity. General relativity is proven on hard facts. Nothin' fancy.
There is an excellent book about Water and UFOs which lists 100s of cases proving that its just gravitomagnetic field.
Mind you, its not any easier for us to make gravitomagnetic field than a Alcubiere's warp drive. As I understand warp drives some theoretical problems, while gravitomagnetic all plain sailing, mathematically speaking?
