The arXiv blog on MIT Technology Review recently reported a breakthrough ‘Physicists Discover the Secret of Quantum Remote Control’ [1] which led some to comment on whether this could be used as an FTL communication channel. In order to appreciate the significance of the paper on Quantum Teleportation of Dynamics [2], one should note that it has already been determined that transfer of information via a quantum tangled pair occurs *at least* 10,000 times faster than the speed of light [3]. The next big communications breakthrough?

Quantum Entanglement Visual

In what could turn out to be a major breakthrough for the advancement of long-distance communications in space exploration, several problems are resolved — where if a civilization is eventually established on a star system many light years away, for example, such as on one of the recently discovered Goldilocks Zone super-Earths in the Gliese 667C star system, then communications back to people on Earth may after all be… instantaneous.

However, implications do not just stop there either. As recently reported in The Register [5], researchers in Israel at the University of Jerusalem, have established that quantum tangling can be used to send data across both TIME AND SPACE [6]. Their recent paper entitled ‘Entanglement Between Photons that have Never Coexisted’ [7] describes how photon-to-photon entanglement can be used to connect with photons in their past/future, opening up an understanding into how one may be able to engineer technology to not just communicate instantaneously across space — but across space-time.

Whilst in the past many have questioned what benefits have been gained in quantum physics research and in particular large research projects such as the LHC, it would seem that the field of quantum entanglement may be one of the big pay-offs. Whist it has yet to be categorically proven that quantum entanglement can be used as a communication channel, and the majority opinion dismisses it, one can expect much activity in quantum entanglement over the next decade. It may yet spearhead the next technological revolution.

1) CERN officially attempted to produce ultraslow miniature black holes on earth. It has announced to continue doing so after the current more than a year-long break for upgrading.

2) Miniature black holes possess radically new properties according to published scientific results that go unchallenged in the literature for 5 years: no Hawking evaporation; unchargedness; invisibility to CERN’s detectors; enhanced chance of being produced.

3) Of the millions of miniature black holes hoped to have been produced, at least one is bound to be slow enough to stay inside earth to circulate there.

4) This miniature black hole circulates undisturbed – until it captures the first charged quark. From then on it grows exponentially doubling in size in months at first, later in weeks.

5) As a consequence, after about 100 doublings, earth will start showing manifest signs of “cancer.” And she will – after first losing her atmosphere – die within months to leave nothing but a 2-cm black hole in her wake that still keeps the moon on its course.

6) CERN’s roundabout-way safety argument of 2008, invoking the observed longevity of neutron stars as a guarantee for earth, got falsified on the basis of quantum mechanics in a paper published in mid-2008.

7) CERN’s second roundabout-way safety argument of 2008, invoking the observed longevity of white dwarf stars as a guarantee for earth, likewise got falsified in scientific papers the first of which was published in mid-2008. CERN overlooked the enlarged-cross section principle valid for ultra-slow artificial, compared to ultrafast natural, miniature black holes. The same effect is frighteningly familiar from the slow “cold” neutrons in nuclear fission.

In summary, seven coincidences of “bad luck” were found to cooperate like Macbeth’s fateful 3 witches. CERN decided to accept the blemish of not up-dating its safety report for 5 years so far. Also it steadfastly refuses the safety conference publicly requested on the web on April 18, 2008 (“Honey, I shrunk the earth”). Most significantly, CERN up to this day refuses to heed a Cologne Court’s advice, handed-out to CERN’s representatives standing before it on January the 27th of 2011, to hold a “safety conference.”

Unless there is a safety guarantee that CERN keeps a secret from the whole world while mentioning it only behind closed doors to bring the World Press Council and the UN Security Council to refrain from doing their otherwise inalienable duty, the above-sketched scenario has no parallel in history.

Not a single scientific publication world-wide claims to falsify one of the above-sketched results (points 2–7). Only a very charismatic scientist may be able to call back the media and the mighty behind closed doors. I have a hunch who this could be. But I challenge him to no longer hide so the world can see to whom she owes her hopefully beneficial fate.

Has there ever been a more unsettling story kept from the citizens of this planet?

The Rocky Mountain chapter of the American Institute of Astronautics & Aeronautics (AIAA) will be having their 2nd Annual Technical Symposium, October 25 2013. The call for papers ends May 31 2013. I would recommend submitting your papers. This conference gives you the opportunity to put your work together in a cohesive manner, get feedback and keep your copyrights, before you write your final papers for journals you will submitting to. A great way to polish your papers.

Here is the link to the call for papers: http://www.iseti.us/pdf/RMAIAA_Call_For_Abstracts_2013-0507.pdf

Here is the link to the conference: http://www.iseti.us/pdf/RMAIAA_General_Advert_2013-0507.pdf

I’ll be presenting 2 papers. The first is a slightly revised version of the presentation I gave at the APS April 2013 conference here in Denver (http://www.iseti.us/WhitePapers/APS2013/Solomon-APS-April(20…45;15).pdf). The second is titled ‘The Mechanics of Gravity Modification’.

Fabrizio Brocca from Italy wanted to know more about the Ni field shape for a rotating-spinning-disc. Finally, a question from someone who has read my book. This is not easy to explain over email, so I’m presenting the answers to his questions at this conference, as ‘The Mechanics of Gravity Modification’. That way I can reach many more people. Hope you can attend, read the book, and have your questions ready. I’m looking forward to your questions. This is going to be a lively discussion, and we can adjourn off conference.

My intention for using this forum to explain some of my research is straight forward. There will be (if I am correct) more than 100 aerospace companies in attendance, and I am expecting many of them will return to set up engineering programs to reproduce, test and explore gravity modification as a working technology.

Fabrizio Brocca I hope you can make it to Colorado this October, too.

The University of Colorado Boulder holds its annual Gamow Memorial Lecture around this time of the year. This year, Feb 26, 2013, Brian Greene gave the lecture, on multiverses.

His talk was very good. He explained why there are 10500 possible variations to possible universes, and ours was just one of many possible universes, thus the term multiverse.

How interesting. This is an extension of the idea that the Earth or the Sun not being at the center of our Universe.

Brian Green graciously allowed me to have my picture taken with him at the reception held in honor of him after his lecture. In the middle picture I am getting ready my new Nokia Lumia 920 Windows 8 phone.

I may not agree with string theories, but I think it is vitally important to allow all forms of physical theories to take root, and let the community of physicists & engineers determine which theories have a better chance of explaining some aspect of the universal laws of physics, through discussions and experimentations. I would add, and drive new commercially viable technologies.

1. Thou shalt first guard the Earth and preserve humanity.

Impact deflection and survival colonies hold the moral high ground above all other calls on public funds.

2. Thou shalt go into space with heavy lift rockets with hydrogen upper stages and not go extinct.

The human race can only go in one of two directions; space or extinction- right now we are an endangered species.

3. Thou shalt use the power of the atom to live on other worlds.

Nuclear energy is to the space age as steam was to the industrial revolution; chemical propulsion is useless for interplanetary travel and there is no solar energy in the outer solar system.

4. Thou shalt use nuclear weapons to travel through space.

Physical matter can barely contain chemical reactions; the only way to effectively harness nuclear energy to propel spaceships is to avoid containment problems completely- with bombs.

5. Thou shalt gather ice on the Moon as a shield and travel outbound.

The Moon has water for the minimum 14 foot thick radiation shield and is a safe place to light off a bomb propulsion system; it is the starting gate.

6. Thou shalt spin thy spaceships and rings and hollow spheres to create gravity and thrive.

Humankind requires Earth gravity and radiation to travel for years through space; anything less is a guarantee of failure.

7. Thou shalt harvest the Sun on the Moon and use the energy to power the Earth and propel spaceships with mighty beams.

8. Thou shalt freeze without damage the old and sick and revive them when a cure is found; only an indefinite lifespan will allow humankind to combine and survive. Only with this reprieve can we sleep and reach the stars.

9. Thou shalt build solar power stations in space hundreds of miles in diameter and with this power manufacture small black holes for starship engines.

10. Thou shalt build artificial intellects and with these beings escape the death of the universe and resurrect all who have died, joining all minds on a new plane.

CCC – “Constant c Catastrophe”

Otto E. Rossler

Faculty of Science, University of Tubingen, Auf der Morgenstelle 8, 72076 Tubingen, Germany

Abstract

The historical twist that the universal constancy of the speed of light, c, got abandoned for more than a century is recalled. The new situation, arrived at independently by Richard J. Cook, is outlined along with some of its uplifting consequences. A new metrology and a new cosmology take shape.
(March 15, 2013)

Text

A globally constant c is not a catastrophe in the opinion of the present writer, despite the fact that most everyone feels safe in the fold of the old paradigm. A simplification of physics is almost never a step back. The new situation can be summarized as follows.

In 1907, Einstein realized that relative to the tip of a constantly accelerating long rocketship in outer space, clocks located at the bottom of the rocketship tick slower, e.g. half as fast, than those at the tip [1]. This was “the happiest thought of my life,” he always stressed. The breakthrough allowed him to understand gravitation in the context of his new theory of special relativity described two years before.

To his dismay, however, he was forced to realize that, at the bottom of the long rocketship, the local slowdown of time is accompanied by a numerically equal, visible from above, reduction of the speed of light c even though the latter had been a universal constant in special relativity. Both observable changes (the slowdown and the crawl) remain masked on the lower level itself. The drawback of the reduced c caused Einstein to drop the subject of gravitation for 4 years (until his good friend Ehrenfest lured him back with the related paradigm of the rotating disk). Einstein then would carefully “build around” the drawback mentioned. And the simplest nontrivial solution of the finished general theory of relativity, the Schwarzschild metric, can indeed be written in an equivalent form in which c is globally constant [2].

But how about the riddle of the “creeping” speed of light downstairs in the rocketship and in gravity? The solution to the conundrum emerges from a second look at the famous “Lorentz contraction” which (as is well known) states that a fast-moving car is shortened while keeping its width: Does this fact mean that the shortened car has become anisotropic in its own frame? The answer is no.

Analogously here: the apparently only vertically enlarged “spaghetti people” downstairs in gravity are not distorted in their own frame. They are objectively enlarged in all directions since time is slowed and c is constant. Their lateral size change is masked when viewed from above. Hence c only seems to be creeping in the lateral directions downstairs without being reduced in reality.

“Who ordered that?,” one feels tempted to say. The new size change which follows from the universal constancy of c has been spotted from time to time in the past, cf. [2]. The most convincing mathematical demonstration based on the theory of general relativity was given by Richard J. Cook in a paper entitled “Gravitational space dilation” [3]. A very simple derivation using the equivalence principle is the “Telemach theorem” [4]. Its cousin, the “Olemach theorem” [5], is even simpler (using only angular-momentum conservation and the Bohr radius formula of quantum mechanics).

The thus successfully recovered “Einstein universality of c ” is a bonanza. Global constancy of c implies, for example, that the well-known infinite time delay of light going all the way down to a black hole’s horizon (or up from it) [6] reflects an infinite distance (if in s/t = c = const., t goes to infinity, so does s ). Therefore the famous “Flamm’s paraboloid” describing the shape of space-time around a Schwarzschild black hole now gets replaced by (is morphed into) a “generic 3-pseudosphere”: Space itself is infinitely enlarged towards the horizon in a trumpet-like fashion. While this is hard to visualize, the lower-dimensional analog, a halved 2-pseudosphere (replacing the upper part of the likewise 2-dimensional Flamm-paraboloid) looks like a vertical infinitely long trumpet whose upper rim and its neighborhood coincides with that of the former paraboloid. An ant placed on the locally flat rim of the trumpet’s big mouth can walk around it in a short finite time. But the same ant has to muster an infinite distance in order to reach the middle of the very same plane – namely the mouthpiece of the maximally drawn-out trumpet (which represents the horizon of the black hole). Thus, “curvature” and “stretching” do both go to infinity near the horizon like Siamese twins, in the new differential geometry of gravitation.

Further new implications are as follows: Rest mass and charge both go to zero in inverse proportion to the local redshift [4]. The charge change represents a major surprise in physics following a 1½ centuries long reign of the law of charge conservation. In consequence of this, the combined “Einstein-Maxwell equations” cease to be physically valid, as do other compound solutions [4]. The same fatal fate holds true, for all expanding-universe solutions to the Einstein equation since they imply global non-constancy of the speed of light c as is well known. Therefore cosmology suddenly finds itself to be on the lookout for a replacement for the big bang. A major catastrophe in view of a decades-long previous consensus.

Equally important, numerous changes in metrology follow if distances, masses and charges are no longer the same as before: The Ur-meter, the Ur-charge (of the electron) and the Ur-kilogram all cease to be valid along with other previous constants of nature, as the price to pay for c’s newly won universality [4]. Hence a new global picture of space-time including the cosmos is implicit. This prospect is almost unacceptable at first sight. By coincidence, though, a new “second statistical mechanics” – cryodynamics sister discipline to thermodynamics – was recently found to exist [7] which independently calls for a new cosmology and is bound to help in its formulation.

To conclude, space-time theory acquires a new symmetry between curvature and stretching in the wake of the new global constancy of the speed of light. General relativity acquires a new face without losing its beauty. The speed of light c thus proves as fertile as it was a century ago. Is it conceivable that Einstein will dominate the 21st century no less than the 20th?

If, we as a community, are intending to accelerate the development of interstellar travel we have to glower at the record and ask ourselves some tough questions. First, what is the current record of the primary players? Second, why is everyone afraid to try something outside the status quo theories?

At the present time the primary players are associated with the DARPA funded 100-Year Starship Study, as Icarus Interstellar who is cross linked with The Tau Zero Foundation and Centauri Dreams is a team member of the 100YSS. I was surprised to find Jean-Luc Cambier on Tau Zero.

Gary Church recently put the final nail in the Icarus Interstellar‘s dreams to build a rocket ship for interstellar travel. In his post on Lifeboat, Cosmic Ray Gorilla Gary Church says “it is likely such a shield will massive over a thousand tons”. Was he suggesting that the new cost of an interstellar rocket ship is not 3.4x World GDP but 34x or 340x World GDP? Oops!

Let us look at the record. Richard Obousy of Icarus Interstellar and Eric Davis of Institute for Advanced Studies claimed that it was possible, using string theories to travel at not just c, the velocity of light but at 1E32c, or c multiplied by a 1 followed by 32 zeros. However, Lorentz-FitzGerald transformations show that anything with mass cannot travel faster than the velocity of light. Note that Lorentz-FitzGerald is an empirical observation which was incorporated into Einstein’s Special Theory of Relativity.

It is quite clear that you can use string theories to say anything you want. I used the term ‘mathematical conjecture’.

In April 2008 the esteemed Michio Kaku said in his Space Show interview, that it would take several hundred years to do gravity modification. But Michio Kaku is a string theorist himself. And I might add down to Earth one at that, since his opinion contradicts Richard Obousy and Eric Davis.

Then there is George Hathaway also with the Tau Zero Foundation who could not reproduce Podkletnov’s experiments, even when he was in communication with Podkletnov.

And this is the one group our astronaut Mae Jemison, leader of the 100YSS effort, has teamed up with? My sincerest condolences to you Mae Jemison. Sincerest condolences.

For the answer to the second question, you have to look within yourselves.

Gravity Modification – New Tools

To understand why gravity modification is not yet a reality, let’s analyze other fundamental discoveries/inventions that changed our civilization or at least the substantially changed the process of discovery. There are several that come to mind, the atomic bomb, heavier than air manned flight, the light bulb, personal computers, and protein folding. There are many other examples but these are sufficient to illustrate what it takes. Before we start, we have to understand four important and related concepts.

(1) Clusters or business clusters, first proposed by Harvard prof. Michael Porter, “a business cluster is a geographic concentration of interconnected businesses, suppliers, and associated institutions in a particular field. Clusters are considered to increase the productivity with which companies can compete, nationally and globally”. Toyota City which predates Porter’s proposal, comes to mind. China’s 12 new cities come to mind, and yes there are pro and cons.

(2) Hot housing, a place offering ideal conditions for the growth of an idea, activity, etc. (3) Crowdsourcing, is a process that involves outsourcing tasks to a distributed group of people. This process can occur both online and offline. Crowdsourcing is different from an ordinary outsourcing since it is a task or problem that is outsourced to an undefined public rather than a specific body. (4) Groundswell, a strong public feeling or opinion that is detectable even though not openly expressed.

I first read about the fascinating story of the making of the atom bomb from Stephane Groueff’s The Manhattan Project-the Making of the Atomic Bomb, in the 1970s. We get a clear idea why this worked. Under the direction of Major General Leslie Groves, and J. Robert Oppenheimer the US, UK & Canada hot housed scientist, engineers, and staff to invent and produce the atomic bomb physics, engineering and manufacturing capabilities. Today we term this key driver of success ‘hot housing’, the bringing together a group of experts to identify avenues for further research, to brainstorm potential solutions, and to test, falsify and validate research paths, focused on a specific desired outcome. The threat of losing out to the Axis powers helped increase this hot housing effect. This is much like what the Aspen Center for Physics is doing (video here).

In the case of the invention of the light bulb, the airplane, and the personal computer, there was a groundswell of public opinion that these inventions could be possible. This led potential inventors with the necessary basic skills to attempt to solve these problems. In the case of the incandescent light bulb, this process took about 70 years from Humphrey Davy in 1809, to Thomas A. Edison and Joseph Wilson Swan in 1879. The groundswell started with Humphrey and had included many by the time of Edison in 1879.

In the case of the airplane the Wright brothers reviewed other researchers’ findings (the groundswell had begun much earlier), and then invented several new tools & skills, flight control, model testing techniques, test pilot skills, light weight motors and new propeller designs.

The invention of the personal computer had the same groundswell effect (see Homebrew Computer Club & PBS TV transcripts). Ed Roberts, Gordon French, Fred Moore, Bob Harsh, George Morrow, Adam Osborne, Lee Felsenstein, Steve Jobs, Steve Wozniak, John Draper, Jerry Lawson, Ron Jones and Bill Gates all knew each other before many of them became wealthy and famous. Bill Gates wrote the first personal computer language, while the others invented various versions of the microcomputer, later to be known as the personal computer, and peripherals required. They invented the products and the tools necessary for the PC industry to take off.

With protein folding, Seth Cooper, game designer, developed Fold It, the tool that would make the investigation into protein folding accessible to an undefined public. Today we describe this ‘crowdsourcing’. Notice that here it wasn’t a specialized set of team that was hot housed, but the reverse, the general public, were given the tools to make crowdsourcing a viable means to solving a problem.

Thus four key elements are required to foster innovation, basic skills, groundswell, hothouse or crowdsourcing, and new tools.

So why hasn’t this happened with gravity modification? Some form of the groundswell is there. In his book The Hunt for Zero Point, Nick Cook (an editor of the esteemed Jane’s Defense Weekly) describes a history that goes back to World War II, and Nazi Germany. It is fund reading but Kurt Kleiner of Salon provides a sober review of The Hunt for Zero Point.

There are three primary reasons for this not having happened with gravity modification. First, over the last 50 years or so, there have only been about 50 to 100 people (outside of black projects) who have investigated this in a scientific manner. That is, the groundswell of researchers with the necessary basic skills has not reached a critical mass to take off. For example, protein folding needed at least 40,000 participants, today Fold It has 280,000 registered participants.

Second, pseudoscience has crept into the field previously known as ‘antigravity’. In respectable scientific circles the term used is gravity modification. Pseudoscience, has clouded the field, confused the public’s perception and chased away the talent – the 3 C’s of pseudoscience. Take for example, plutonium bomb propulsion (written by a non-scientist/non-engineer), basic investigation shows that this is neither feasible nor legal, but it still keeps being written up as a ‘real’ proposition. The correct term for plutonium bomb propulsion is pseudoscience.

Third reason. Per the definition of gravity modification, we cannot use existing theories to propose new tools because all our current status quo theories require mass. Therefore, short of my 12-year study, no new tools are forth coming.
