There are so many competing ideas on how to realize interstellar propulsion. These include chemical rockets, ion propulsion, nuclear engines, solar sails, atomic bomb pulse detonation, antimatter drives, small black holes, warp drives and much more.

How do we sift through all these competing ideas?

For his objectivity and courage in stating that mathematics has become so sophisticated that it can now be used to prove anything, I have named the approach to solving this interstellar challenge the Kline Directive, in honor of the late Prof. Morris Kline.

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, and to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts, (1) Legal Standing, (2) Safety Awareness, (3) Economic Viability, (4) Theoretical-Empirical Relationship and (5) Technological Feasibility.

Legal Standing: Do we have the protection of the law?

Mr. Gregory W. Nemitz of The Eros Project is the first person I know, who pushed the limits of the law. As a US taxpayer, Nemitz claimed ownership of Asteroid 433, Eros, and invoiced NASA $20,000 for parking and storage of the NEAR Shoemaker spacecraft. Citing faulty interpretation of the Outer Space Treaty of 1967, NASA refused to pay. On April 26, 2004 U.S. District Court Judge Howard McKibben dismissed the case. We have to address this. What is to stop other governments from imposing taxes on our outer space commercial activities that is “for the benefit and in the interests of all countries”?

Safety Awareness: Can we protect our crew and our planet?

In the heady rush to propose ideas for new propulsions systems or star drives it is very easy to overlook safety considerations. Quoting E.J. Opik, “Is Interstellar Travel Possible?” Irish Astronomical Journal, Vol 6, page 299. “The exhaust power of the antimatter rocket would equal the solar energy power received by the earth — all in gamma rays”. And Opik quotes the eminent Carl Sagan, Planet. Space Sci., pp. 485–498, 1963, “So the problem is not to shield the payload, the problem is to shield the earth”.

Economic Viability: Can realistic commercial viability be determined?

Space exploration economic viability is not an accounting problem that can be solved by CFOs and accountants. This economic viability is a physics and engineering problem. For example, chemical rocket propulsion to Alpha Centauri, our nearest star, would cost about $1.19x10^14 or 23x 2011 world GDP.

Theoretical-Empirical Relationship: Is the hypothesis empirically sustainable?

String theories are a good example of a theoretical-empirical relationship that is yet to be proved. Let’s remember Prof. Morris Kline’s words when theorist claim a velocity of 10^32 x c (velocity of light) is achievable. Don’t get me wrong. Mathematics is vital to the progress of the sciences, but it needs to be tempered with real world experimental evidence, otherwise it is just conjecture, and ties up our search for interstellar propulsion technologies.

The reverse is equally valid. Without the theoretical underpinnings, there will not be much experimental progress. Podkletnov’s gravity shielding experiments are a good example. In 2 decades since Podkletnov published his experiments, there has not been any experimental progress. My inference is that none of the proposed theoretical explanations addressed all the observations and therefore, could not guide future experiments.

Technological Feasibility: Does it work?

Technological feasibility in a realistic and finite time frame is vital. Technological feasibility quickly leads back to the question of commercial viability. Developing future feasible technologies is an iterative process between technological feasibility and commercial viability, until we can reach the stars without having to ask the question, whom do we select to leave Earth?

Applying the Kline Directive, a quick method of eliminating competing technologies is to construct the Interstellar Challenge Matrix that compares the pros and cons of each competing propulsion technology.

Can we hasten the development of interstellar propulsion technologies? Yes.

Since disproving the validity of Alcubierre-type warp drives, interstellar propulsion physics is currently non-existent. To birth this propulsion physics, in 2012, I classified physical hypotheses/theories into 3 categories (1) Type 1: The Millennium Theories, (2) Type 2: The 100-Year Theories and (3) Type 3: The Engineering Feasible Theories.

Type 1, Millennium Theories require more than a 100 years and maybe up to 1,000 years to prove or disprove. Mathematically correct but inscrutable with physically verifiable experiments, even in the distant future. String and quantum gravity theories fall into this category. Why? If we cannot even figure out how to engineer-modify 4-dimensional spacetime, how are we going to engineer-modify a 5-, 6-, 9-, 11- or 23-dimensional universe?

Type 2, 100-Year Theories show promise of being verified with technologies that would require several decades to engineer, test and validate, and do not lend themselves to an immediate engineering solution. The engineering solution is theoretically feasible but a working experiment or technology is some decades away as the experimental or physical implementation is not fully understood.

Type 3, Engineering Feasible Theories lend themselves to engineering solutions, today. They are falsifiable today, with our current engineering technologies, if one knows what to test for and how to test for these experimental observations.

We as a society need to apply the Kline Directive to invent new propulsion physics theories, that are at best Engineering Feasible and at worst 100-Year theories.

We now have the tools to quickly eliminate both theoretical and experimental proposals that are highly likely to be unproductive, and focus on those that truly have potential of delivering commercial interstellar propulsion technologies. In the US money is no object, as the combined 2015 DARPA and NSF budgets, is $10.26 billion. Allocating a very small slice of these budgets for propulsion physics would be an enormous step forward.

(This article was originally published in the Huffington Post.)

In a previous post on Technological Feasibility I had stated that a quick and dirty model shows that we could achieve velocity of light c by 2151 or the late 2150s. See table below.

That is, at the current rate of technological innovation we could as a civilization reach light speed in about 140 years.  More importantly we could not even reach anywhere near that within the next 100 years. Our capability would be 6.3% of c.

The Lorentz-Fitzgerald transformation informs us light speed would require an infinite amount of energy (i.e. more than there is in the Universe!), thereby highlighting the weaknesses in these types of technological forecasting methods.  But these models still serve a purpose. They provide some guidance as to what is possible and when. The operative word is guidance.

Rephrasing is required. Is the technological light speed horizon of the 2150s too far out? If you are as impatient as I am the answer is ‘yes’.  It would not be in the spirit of the Kline Directive to accept a 2150s horizon. 2150s is for people with no imagination, people who have resigned to the inevitable snail’s progress of physics. Further, we now know the inevitable impossibility using our contemporary physics because of the 5 major errors.

Completing the Interstellar Challenge Matrix (ICH) gives:

PDF version available here.

What are we left with? We have to find new directions, new models, new mathematical constructions, that address all 5 errors. And in the spirit of the Kline Directive, there needs to be a better method of sifting through academic papers “ … to provide reasonability in guidance and correctness in answers to our questions in the sciences …”

What do we do for starters? Here are my initial recommendations are:

1.            The physics community has to refocus on mathematical construction hypotheses.

2.            More experimental physicist leading combined teams of experimental and theoretical physicist.

3.            Prioritize research funding by Engineering Feasible Theories, 100-Year Theories, and only then Millennium Theories.

I started this series of blog posts in order to achieve interstellar travel sooner rather than later, but we as a community are heading in the wrong direction. It won’t work to build bigger carriages. It won’t work add more horses, as some would suggest. That would be like flogging a dead horse. We have to do something radically different. That is why the Kline Directive matters.

I have made the assumption that technological feasibility is a necessary step. Yes it is, given our lack of technological capability to reach the stars in a realistic and finite time frame. Technology feasibility very quickly leads back to the next question of commercial viability, the second step.

Future feasible technologies will iterate between technological feasibility and commercial viability until we can reach the stars in a manner we don’t have to ask the question, whom do we select to leave Earth?

Until then we are not ready!

In this post I have updated the Interstellar Challenge Matrix (ICM) to guide us through the issues so that we can arrive at interstellar travel sooner, rather than later:

Interstellar Challenge Matrix (Partial Matrix)

It is quite obvious that the major impediments to interstellar travel are the Millennium Theories. Let us review. Richard Feynman (Nobel Prize 1965) & Sheldon Lee Glashow (Nobel Prize 1979) have criticized string theory for not providing novel experimental predictions at accessible energy scales, but other theoretical physicists (Stephen Hawking, Edward Witten, Juan Maldacena and Leonard Susskind) believe that string theory is a step towards the correct fundamental description of nature. The Wikipedia article String Theory gives a good overview, and notes other critics and criticisms of string theories. In What is String Theory? Alberto Güijosa explains why string theories have come to dominate theoretical physics. It is about forces, and especially about unifying gravity with the other three forces.

Note, strings expand when their energy increases but the experimental evidence aka Lorentz-Fitzgerald transformations tell us that everything contracts with velocity i.e. as energy is increased.

In my opinion, the heady rush to a theory of everything is misguided, because there is at least one question that physics has not answered that is more fundamental than strings and particles. What is probability and how is it implemented in Nature?

Probabilities are more fundamental than particles as particles exhibit non-linear spatial probabilistic behavior. So how can one build a theory of everything on a complex structure (particles), if it cannot explain something substantially more fundamental (probabilities) than this complex structure? The logic defies me.

We can ask more fundamental questions. Is this probability really a Gaussian function? Experimental data suggests otherwise, a Var-Gamma distribution. Why is the force experienced by an electron moving in a magnetic field, orthogonal to both the electron velocity and the magnetic field? Contemporary electromagnetism just says it is vector cross product, i.e. it is just that way. The cross product is a variation of saying it has to be a Left Hand Rule or a Right Hand Rule. But why?

Is mass really the source of a gravitational field? Could it not be due to quark interaction? Can we device experiments that can distinguish between the two? Why do photons exhibit both wave and particle behavior? What is momentum, and why is it conserved? Why is mass and energy equivalent?

Can theoretical physicists construct theories without using the laws of conservation of mass-energy and momentum? That would be a real test for a theory of everything!

In my research into gravity modification I found that the massless formula for gravitational acceleration, g=τc², works for gravity, electromagnetism and mechanical forces. Yes, a unification of gravity and electromagnetism.  And this formula has been tested and verified with experimental data. Further that a force field is a Non Inertia (Ni) field, and is present where ever there is a spatial gradient in time dilations or velocities. This is very different from the Standard Model which requires that forces are transmitted by the exchange of virtual particles.

So if there is an alternative model that has united gravity and electromagnetism, what does that say for both string theories and the Standard Model? I raise these questions because they are opportunities to kick start research in a different direction. I answered two of these questions in my book. In the spirit of the Kline Directive can we use these questions to explore what others have not, to seek what others will not, to change what others dare not?

That is why I’m confident that we will have real working gravity modification technologies by 2020.

In concluding this section we need to figure out funding rules to ensure that Engineering Feasible and 100-Year Theories get first priority. That is the only way we are going to be able to refocus our physics community to achieve interstellar travel sooner rather than later.

1. Legal Standing. 2. Safety Awareness. 3. Economic Viability. 4. Theoretical-Empirical Relationship. 5. Technological Feasibility.

In Part 1, we learned that Einstein was phenomenally successful because his work was deeply meshed with the experimental evidence of the day. In Part 2, we learned that to be successful at developing new useful theories and discovering new fundamental properties of Nature that will bring forth new interstellar travel technologies, we need to avoid hypotheses that are not grounded in experimental data, as these are purely mathematical conjectures.

In my book on gravity modification I classified physics hypotheses and theories into 3 categories, as follows:

A. Type 1: The Millennium Theories
These are theories that would require more than a 100 years and up to 1,000 years to prove or disprove. Mathematically correct but inscrutable with physical verifiable experiments, even in the distant future.

String and quantum gravity theories fall into this category. Why? If we cannot even figure out how to engineer-modify 4-dimensional spacetime, how are we going to engineer-modify a 5-, 6-, 9-, 11- or 23-dimensional universe?

How long would it take using string theories to modify gravity? Prof. Michio Kaku in his April 2008 Space Show interview had suggested several hundred years. Dr. Eric Davis in his G4TV interview had suggested more than 100 years maybe 200 years. So rightly, by their own admission these are Millennium Theories. It should be noted that Richard Feynman (Nobel Prize 1965) & Sheldon Lee Glashow (Nobel Prize 1979) were against string theory, but their opinions did not prevail.

Even hypotheses that conjecture time travel should be classified as Millennium Theories because they require ‘exotic’ matter. John Eades, a retired CERN senior scientist, in his article Antimatter Pseudoscience, states in no uncertain terms that antimatter is impossible to handle and create in real quantities. Then what about exotic matter?

For that matter any hypothesis that requires antimatter or exotic matter should be classified a Millennium Theory.

B. Type 2: The 100-Year Theories
These are theories that show promise of being verified with technologies that would require several decades to engineer, test and prove.

These types of theories do not lend themselves to an immediate engineering solution. The engineering solution is theoretically feasible but a working experiment or technology is some decades away, because the experimental or physical implementation is not fully understood.

Note there is this gap. We do not have 100-Year Theories in our repertoire of physical theories to keep the pipeline supplied with new and different ways to test the physical Universe.

C. Type 3: The Engineering Feasible Theories
These are theories that lend themselves to an engineering solution, today. They are falsifiable today, with our current engineering technologies. They can be tested and verified in the laboratory if one knows what to test for and how to test for these experimental observations.

Today Relativity falls into this category because we have the engineering sophistication to test Einstein’s theory, and it has been vindicated time and time again. But, there is a very big ‘but’. But Relativity cannot give us gravity modification or new propulsion theories, because it requires mass. We need to stand on Einstein’s shoulders to take the next step forward.

Therefore, if we are to become an interstellar civilization, in the spirit of the Kline Directive, we need to actively seek out and explore physics in such a manner as to bring forth Engineering Feasible and 100-Year Theories.

We need to ask ourselves, what can we do, to migrate the theoretical physics research away from Theory of Everything research to the new field of propulsion physics? Gravity modification is an example of propulsion physics. Here is the definition of gravity modification, from my book:

“Gravity modification is defined as the modification of the strength and/or direction of the gravitational acceleration without the use of mass as the primary source of this modification, in local space time. It consists of field modulation and field vectoring. Field modulation is the ability to attenuate or amplify a force field. Field vectoring is the ability to change the direction of this force field.”

Note by this definition requiring no mass, relativity, quantum mechanics and string theories cannot be used to theorize propulsion physics. Therefore, the urgent need to find genuinely new ways in physics, to achieve interstellar travel.

Can we get there? The new physics? To answer this question let me quote Dr. Andrew Beckwith, Astrophysicist, Ph.D.(Condensed Matter Theory) who wrote the Foreword to my book:

“I believe that Quantum Mechanics is an embedded artifact of a higher level deterministic theory, i.e. much in the same vein as G. t’Hooft, the Nobel prize winner. In this sense, what Benjamin has done is to give a first order approximation as to what Quantum Mechanics is actually a part of which may in its own way shed much needed understanding of the foundations of Quantum Mechanics well beyond the ‘Pilot model’ of DICE 2010 fame (this is a conference on the foundations of Quantum Mechanics and its extension given once every two years in Pisa , Italy, organized by Thomas Elze).”

Why does Dr. Andrew Beckwith reference quantum mechanics in a book on gravity modification?

Because my investigation into gravity modification led me to the conclusion that gravitation acceleration is independent of the internal structure of the particle. It does not matter if the particle consists of other particles, strings, pebbles or rocks. This led me to ask the question, so what is the internal structure of a photon? I found out that the photon probability is not Gaussian but a new distribution, Var-Gamma. Therefore I believe Robert Nemiroff’s three photon observation will be vindicated by other physicist-researchers sifting through NASA’s archives for gamma-ray burst.
