I was recently accused on another blog of repeating a defeatist mantra.
My “mantra” has always been WE CAN GO NOW. The solutions are crystal clear to anyone who takes a survey of the available technology. What blinds people is their unwillingness to accept the cost of making it happen.
There is no cheap.
Paul Gilster comments on his blog Centauri Dreams, concerning Radiation, Alzheimer’s Disease and Fermi;
“Neurological damage from human missions to deep space — and the study goes no further than the relatively close Mars — would obviously affect our planning and create serious payload constraints given the need for what might have to be massive shielding.”
Massive shielding.
This is the game changer. The showstopper. The sea change. The paradigm shift.
The cosmic ray gorilla. Whatever you want to call it, it is the reality that most of what we are familiar with concerning human space flight is not going to work in deep space.
Massive Shielding=Nuclear Propulsion=Bombs
M=N=B
We have to transport nuclear materials to the Moon where we can light off a nuclear propulsion system. The Moon is where the ice-derived Water to fill up a Massive radiation shield is to be found.
Massive Shield=Water=Lunar Base
M=W=L
Sequentially: L=W=M=N=B
So, first and last, we need an HLV to get to this Lunar Base (where the Water for the shield is) and we need to safely transport Nuclear material there (and safely assemble and light off the Bombs to push the shield around).
Radiation shielding is the first determining factor in spaceship design and this largely determines the entire development of space travel.
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.

Einstein Mining

Einstein Mining
Otto E. Rossler, Faculty of Science, University of Tubingen, Germany
The young Einstein was the most fertile scientific mind of history. He first saw the observer-private nature of simultaneity, a consequence of the global constancy of the speed of light c valid in Maxwell’s equation. He then spotted the twin miracle (“paradox”): that a returned twin clock is younger than its stay-put sibling. The transversal Doppler effect described in the same 1905 paper was equally new. At the end of this miraculous year stood the improved Weber law (E exactly equal m times c-square) destined to become tragically consequential when Lise Meitner would recall its strength 34 years into the future. Two years after the miraculous year, there followed Einstein’s biggest discovery in the present author’s mind: the gravitational clock slowdown near the bottom of a constantly accelerating rocketship compared to a twin clock in its tip. It implies a second twin paradox (spending time downstairs lets you stay younger in Alan Lightman’s phrase).
This bundle of subsequently observationally confirmed predicted effects is an eternal heritage. Maxwell’s advice: go back to the origin of an already discovered gold vein since it is there that others inevitably originate is still valid. This is the excuse for the new notion of “Einstein mining.”
Specifically, the idea put forward here is that the clock slowdown on the lower floor – the gravitational twin paradox – stands not alone. This triggers the following naïve question: What happens to angular-momentum conservation when all processes are slowed-down downstairs? In special relativity, angular momentum is known to be conserved. So it must be conserved near the bottom of Einstein’s constantly accelerated rocketship which is described by special relativity alone, and then by analogy also on a lower floor in gravity.
This apparently new question is not hard to check. A horizontally rotating frictionless bicycle wheel (a massive ring with a fixed hub in the middle) can be suspended from a torque-free thread that is attached to its hub, allowing in this way to be lowered and hauled-up again inside the accelerating rocketship (or in gravity in Lewin’s lecture hall). What happens if angular momentum is conserved in the slowed-down wheel downstairs?
This is a typical “thought experiment with consequences” in the Einstein fashion. Please, lower the wheel carefully and haul it up again equally carefully. Then we know that a number of rotational ticks will have been skipped in the past of our retrieved wheel-clock. However, what happened to angular momentum in the meantime at the reduced rotation speed downstairs? How was it conserved since the ticking speed and hence angular momentum must be the same again after the hauling-up procedure as Einstein showed for any type of clock? Thus, angular momentum is bound to have been conserved all the way down and up again by our rotational clock in spite of the intervening reduced rotation rate that was in charge downstairs. If the rotation speed was reduced while angular momentum was conserved, something else is bound to have changed downstairs to make up for the change in rotation rate. Otherwise, angular momentum could not have been conserved continually.
Fortunately, angular momentum J happens to be determined by very few factors apart from the rotation rate omega itself, in our horizontally rotating bicycle wheel. It is only two factors: radius and mass. The formula reads at low speeds which suffice for the purpose:
J = constant = omega times radius-squared times mass (1)
Here omega is the rotation rate which as we saw is reduced downstairs. What is it that you are going to bet for the remaining two factors, mass and radius? There are 4 linear factors standing on the right hand side (omega, radius, radius, mass) the product of which is constant if angular momentum J is to be preserved.
Any combined change law of the mass and the radius which is able to compensate for the change in omega is a candidate. This includes the possibility that one of the two variables, radius and mass, stays unchanged (for example, mass). Simplicity calls for linearity (proportionality or anti-proportionality) regarding either of the two (size and mass). If size goes up in direct proportion with omega and mass goes down by the same factor, J is also conserved downstairs. Does this simplest – since linear – case make any sense? It makes physical sense for an independent reason due to Einstein. He showed in 1907 that the energy of a locally emitted photon is reduced downstairs in parallel to the reduction in the ticking (here rotation) rate. Quantum mechanics subsequently showed that the mass-energy of the photon can be locally transformed into an ordinary particle of the same rest-mass energy in principle and vice versa. Positronium is a case in point. Picture one of those familiar “PET” machines to be operating downstairs. Thus the masses of all particles that are locally at rest downstairs are reduced in parallel with the ticking rate.
This finishes our foray into the mind of Einstein. We were able to extract one more feature from his most important finding, gravitational time dilation. Diameters (radii, lengths) go up in proportion, while masses go down. And – as the example of positronium annihilation shows in addition – charge goes down along with the rest mass since the two keep their ratio locally on every particle. The so obtained final result (omega down, r up, r up, m down, q down) can be remembered by the acronym “Olemach” since omega O, length L, mass M and charge Ch are involved.
This is the strength of angular-momentum conservation when entered into Einstein’s gravitational time dilation. Who would have thought that such a simple deep result is still possible? The consequences are staggering as usual with Einstein (black holes acquire totally new features, for example). But this is not our topic. We are happy to have found another implication of Einstein’s mind.
I thank Ali Sanayei for a discussion. For J.O.R.
I recently posted this on the only two other sites that will allow me to express my opinions;
I see the problem as one of self similarity; trying to go cheap being the downfall of all these schemes to work around human physiology.
When I first became interested in space travel several years ago I would comment on a couple blogs and find myself constantly arguing with private space proponents- and saying over and over again, “there is no cheap.” I was finally excommunicated from that bunch and banned from posting. They would start calling me an idiot and other insults and when I tried to return the favor the moderator would block my replies. The person who runs those two sites works for a firm promoting space tourism- go figure.
The problem is that while the aerospace industry made some money off the space program as an outgrowth of the military industrial complex, it soon became clear that spaceships are hard money- they have to work. The example of this is the outrage over the Apollo 1 fire and subsequent oversight of contractors- a practice which disappeared after Apollo and resulted in the Space Shuttle being such a poor design. A portion of the shuttle development money reportedly went under the table into the B-1 bomber program; how much we will never know. Swing wings are not easy to build which is why you do not see it anymore; cuts into profits.
The easy money of cold war toys has since defeated any move by industry to take up the cause of space exploration. No easy money in spaceships. People who want something for nothing rarely end up with anything worth anything. Trying to find cheap ways around furnishing explorers with the physcial conditions human beings evolved in is going to fail. On the other hand if we start with a baseline of one gravity and Earth level radiation we are bound to succeed.
The engineering solutions to this baseline requirement are as I have already detailed; a tether for gravity and a massive moonwater shield with bomb propulsion. That is EXACTLY how to do it and I do not see any one else offering anything else that will work- just waffling and spewing about R&D.
We have been doing R&D for over half a century. It is a reason to go that is supposedly lacking.
When that crater in Mexico was discovered in 1980 the cold war was reaching it’s crescendo and the massive extinction it caused was overshadowed by the threat of nuclear weapons. Impact defense is still the only path to all that DOD money for a Moon base.
Recently, I met Josh Hopkins of Lockheed’s Advanced Programs, AIAA Rocky Mountain Region’s First Annual Technical Symposium (RMATS), October 26, 2012. Josh was the keynote speaker at this RMATS. Here is his presentation. After his presentation we talked outside the conference hall. I told him about my book, and was surprised when he said that two groups had failed to reproduce Podkletnov’s work. I knew one group had but a second? As we parted we said we’d keep in touch. But you know how life is, it has the habit of getting in the way of exciting research, and we lost touch.
About two weeks ago, I remembered, that Josh had said that he would provide some information on the second group that had failed to reproduce Podkletnov’s work. I sent him an email, and was very pleased to hear back from him and that the group’s finding had been published under the title “Gravity Modification by High-Temperature Semiconductors”. The authors were C. Woods, S. Cooke, J. Helme & C. Caldwell. Their paper was published in the 37th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 8–11 July 2001, Salt Lake City, Utah. I bought a copy for the AIAA archives, and read it, reread it, and reread it.
Then I found a third team they published their lack of findings “Gravity Modification Experiments Using a Rotating Superconducting Disk and Radio Frequency Fields”. The authors were G. Hathaway, B. Cleveland and Y. Bao. Published in Physica C, 2003.
Both papers focused on attempting to build a correct superconducting disc. At least Wood et al said “the tests have not fulfilled the specified conditions for a gravity effect”. The single most difficult thing to do was to build a bilayered superconducting disc. Woods et al tried very hard to do so. Reading through Hathaway et all paper suggest that they too had similar difficulties. Photo shows a sample disc from Woods’ team. Observe the crack in the middle.
Further, Woods’ team was able to rotate their disc to 5,000 rpm. Hathaway’s team reports a rotational speed of between 400–800 rpm, a far cry from Podkletnov’s 5,000 rpm. This suggests that there were other problems in Hathaway’s disc not reported in their paper. With 400–800 rpm, if Hathaway were to observe a significant weight change it would have been less than the repeatable experimental sensitivity of 0.5mg!
Here are some quotes from Hathaway et al’s original paper “As a result of these tests it was decided that either the coil designs were inefficient at producing …”, “the rapid induction heating at room temperature cracked the non-superconducting disk into two pieces within 3 s”, “Further tests are needed to determine the proper test set-up required to detect the reverse Josephson junction effect in multi-grain bulk YBCO superconductors”.
It is quite obvious from reading both papers that neither team were able to faithfully reproduce Podkletnov’s work, and it is no wonder that at least Woods et al team stated “the tests have not fulfilled the specified conditions for a gravity effect”. This statement definitely applies to Hathaway et al’s research. There is more to critic both investigations, but .… this should be enough.
Now, for the final surprise. The first team I had mentioned earlier. Ning Li led the first team comprised of members from NASA and University of Huntsville, AL. It was revealed in conversations with a former team member that Ning Li’s team was disbanded before they could build the superconducting discs required to investigate Podkletnov’s claims. Wow!
If you think about it, all these “investigations” just showed that nobody in the US was capable of faithfully reproducing Podkletnov’s experiments to even disprove it.
What a big surprise! A null result is not a disproof.

Excerpt: “Galactic cosmic radiation poses a significant threat to future astronauts,” said M. Kerry O’Banion, M.D., Ph.D., a professor in the University of Rochester Medical Center (URMC) Department of Neurobiology and Anatomy and the senior author of the study. “The possibility that radiation exposure in space may give rise to health problems such as cancer has long been recognized. However, this study shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer’s disease.”
It appears when Eugene Parker wrote “Shielding Space Travelers” in 2006 he was right- and all the private space sycophants claiming radiation mitigation is trivial are wrong.
Only a massive water shield a minimum of 14 feet thick and massing 400 tons for a small capsule can shield human beings in deep space on long duration missions. And since a small capsule will not have sufficient space to keep a crew psychologically healthy on a multi-year journey it is likely such a shield will massive over a thousand tons.
This mass may seem to make Human Space Flight Beyond Earth and Lunar Orbit (HSF-BELO) impractical but in fact it is not an obstacle but an enabler. Nuclear Pulse Propulsion using bombs to push a spaceship to the outer solar sytem becomes more efficient the larger the ship and this amount of water is useful in a closed loop life support system.
Lighting off bombs in the Earth’s magnetosphere is not acceptable and this points to the Moon as the obvious place to launch nuclear missions and also to acquire the water for radiation shielding. The Space Launch System (SLS) is the human-rated Heavy Lift Vehicle (HLV) with a powerful escape system that can safely transport the required fissionables to the Moon.
2013 may be the year of the comet and the year of the spaceship if the two goals of protecting the planet from impacts and establishing off world colonies are finally recognized as vital to the survival of humankind.
May peace break into your home and may thieves come to steal your debts.
May the pockets of your jeans become a magnet for $100 bills.
May love stick to your face like Vaseline and may laughter assault your lips!
May happiness slap you across the face and may your tears be that of joy
May the problems you had, forget your home address!
In simple words .….….……May 2013 be EXTRAORDINARY … the best year of your life!!! Simply the best New Year greeting anyone has sent to me. This was from Robert White of Extraordinary People.
This morning I checked the Lifeboat stats for 2012. When I started blogging for Lifeboat at the end of July, we ended July 2012 with 42,771 unique visitors. We closed 2012 with 90,920 unique visitors for the month December. Wow! Our blogging has become more relevant, and more thought provoking. As a community of bloggers (with the exception of one) we have moved away from the 3 Cs of pseudoscience. Clouding the field. Confusing the public’s perception. Chasing away talent.
How did we do this? By backing up our discussions with hard facts, robust debate and real numbers. From years if not decades of investigation in our field of research. By speaking from our own unique experience. By sharing that unique experience with our readers.
Once again, may 2013 be an extraordinary year.

A happy new year to the human race from it’s most important member; me. Since self-worship seems to be the theme of the new American ideal I had better get right with me.
With my government going over the fiscal cliff it would appear that the damned soul of Ayn Rand is exerting demonic influence on the political system through worship of the individual. The tea party has the Republicans terrified of losing their jobs. Being just like me, those individuals consider themselves the most important person on the planet- so I cannot fault them.
As Ayn Rand believed, “I will not die, it’s the world that will end”, so who cares about the collective future of the human race? Towards the end of 2013 the heavens may remind us the universe does not really care about creatures who believe themselves all important. The choice may soon be seen clearly in the light of the comet’s tail; the glorification of the individual and the certain extinction of our race, or the acceptance of a collective goal and our continued existence.
Ayn Rand made her choice but most of us have time to choose more wisely. I pray for billions, tens and hundreds of billions of dollars- for a Moonbase.
I am not one of the Earth is overpopulated crowd. We could have a high quality of life for every man, woman and child on this planet if we did not, as a species, spend most of our resources pandering to moral weakness and cravings for profit. The myth of scarcity is a smokescreen to obscure the reality of greed and ignorance. Which is why people like Gerard K. O’Neill sought to improve the human condition with space colonies.
We need to go into space to first safeguard the Earth from impacts and the human race from extinction, and along with these missions to spread life into the universe through colonization. None of those three things has anything to do with getting filthy rich or intimidating other nations with our firepower so we can steal their resources. Which is why it has not happened.
Happy New Year with hopes for a more enlightened public.
Happy new year to my Wife, my Daughter, my Father, and to those who give a damn about next year even if they will not be there.
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.
