I first met Dr. Young Bae, NIAC Fellow, at the Defense Advanced Research Projects Agency (DARPA) sponsored 2011, 100 Year Starship Study (100YSS) at Orlando, Fla. Many of us who were there had responded to the NASA/DARPA Tactical Technology Office’s RFP to set up an organization “… to develop a viable and sustainable non-governmental organization for persistent, long-term, private-sector investment into the myriad of disciplines needed to make long-distance space travel viable …”

Yes, both DARPA and NASA are at some level interested in interstellar propulsion. Mine was one of approximately 35 (rumored number) teams from around the world vying for this DARPA grant, and Dr. Bae was with a competing team. I presented the paper “Non-Gaussian Photon Probability Distributions”, and Dr. Bae presented “A Sustainable Developmental Pathway of Photon Propulsion towards Interstellar Flight”. These were early days, the ground zero of interstellar propulsion, if you would.

Dr. Bae has been researching Photon Laser Thrust (PLT) for many years. A video of his latest experiment is available at the NASA website or on YouTube. This PLT uses light photons to move an object by colliding with (i.e. transferring momentum to) the object. The expectation is that this technology will eventually be used to propel space crafts. His most recent experiments demonstrate the horizontal movement of a 1-pound weight. This is impressive. I expect to see much more progress in the coming years.

At one level, Dr. Bae’s experiments are confirmation that Bill Nye’s Light Sail (which very unfortunately lost communications with Earth) will work.

At another level, one wonders why or how the photon, a particle without mass, has momentum that is proportion to the photon’s frequency or energy. A momentum that is observable in Dr. Bae’s and other experiments. This is not a question that contemporary physics asks. Einstein was that meticulous when he derived the Lorentz-FitzGerald Transformations (LFT) from first principles for his Special Theory of Relativity (STR). Therefore, if you think about it, and if we dare to ask the sacrilegious question, does this mean that momentum is a particle’s elementary property that appears to be related to mass? What would we discover if we could answer the question, why does momentum exist in both mass and massless particles? Sure, the short cut don’t bother me answer is, mass-energy equivalence. But why?

At the other end of photon momentum based research is the EmDrive invented by Roger Shawyer. He clearly states that the EmDrive is due to momentum exchange and not due to “quantum vacuum plasma effects”. To vindicate his claims Boeing has received all of his EmDrive designs and test data. This is not something that Boeing does lightly.

In this 2014 video a member of NASA’s Eagleworks explains that the EmDrive (renamed q-thruster) pushes against quantum vacuum, the froth of particle and antiparticle pairs in vacuum. Which raises the question, how can you push against one type and not the other? In 2011, using NASA’s Fermi Gamma-ray Space Telescope photographs, Prof. Robert Nemiroff of Michigan Technological University, made the stunning discovery that this quantum foam of particle and antiparticle pairs in a vacuum, does not exist. Unfortunately, this means that the NASA Eagleworks explanation clearly cannot be correct.

So how does the EmDrive work?

In my 2012 book An Introduction to Gravity Modification, I had explained the importance of asymmetrical fields and designs for creating propellantless engines. For example, given a particle in a gravitational field and with respect to this field’s planetary mass source, this particle will observe an asymmetrical gravitational field. The near side of this particle will experience a stronger field than the far side, and thus the motion towards the planetary mass. Granted that this difference is tiny, it is not zero. This was how I was able to determine the massless formula for gravitational acceleration, g=τc^2, where tau τ is the change in the time dilation transformation (dimensionless LFT) divided by that distance. The error in the modeled gravitational acceleration is less than 6 parts per million. Thus validating the asymmetrical approach.

In very basic terms Shawyer’s New Scientist paper suggests that it is due to the conical shape of the EmDrive that causes microwave photons to exhibit asymmetrical momentum exchange. One side of the conical structure with the larger cross section, has more momentum exchange than the other side with the smaller cross section. The difference in this momentum exchange is evidenced as a force.

However, as Dr. Bae points out, from the perspective of legacy physics, conservation of momentum is broken. If not broken, then there are no net forces. If broken, then one observes a net force. Dr. Beckwith (Prof., Chongqing University, China) confirms that Dr. Bae is correct, but the question that needs to be addressed is, could there be any additional effects which would lead to momentum conservation being violated? Or apparently violated?

To be meticulous, since energy can be transmuted into many different forms, we can ask another sacrilegious question. Can momentum be converted into something else? A wave function attribute for example, in a reversible manner, after all the massless photon momentum is directly proportional to its frequency? We don’t know. We don’t have either the theoretical or experimental basis for answering this question either in the positive or negative. Note, this is not the same as perpetual motion machines, as conservation laws still hold.

Shawyer’s work could be confirmation of these additional effects, asymmetrical properties and momentum-wave-function-attribute interchangeability. If so, the future of propulsion technologies lies in photon based propulsion.

Given that Shawyer’s video demonstrates a moving EmDrive, the really interesting question is, can we apply this model to light photons? Or for that matter, any other type of photons, radio, infrared, light, ultraviolet and X-Rays?

Recent revelations of NASA’s Eagleworks Em Drive caused a sensation on the internet as to why interstellar propulsion can or cannot be possible. The nay sayers pointed to shoddy engineering and impossible physics, and ayes pointed to the physics of the Alcubierre-type warp drives based on General Relativity.

So what is it? Are warp drives feasible? The answer is both yes and no. Allow me to explain.

The empirical evidence of the Michelson-Morley experiment of 1887, now known as the Lorentz-FitzGerald Transformations (LFT), proposed by FitzGerald in 1889, and Lorentz in 1892, show beyond a shadow of doubt that nothing can have a motion with a velocity greater than the velocity of light. In 1905 Einstein derived LFT from first principles as the basis for the Special Theory of Relativity (STR).

So if nothing can travel faster than light why does the Alcubierre-type warp drive matter? The late Prof. Morris Klein explained in his book, Mathematics: The Loss of Certainty, that mathematics has become so powerful that it can now be used to prove anything, and therefore, the loss of certainty in the value of these mathematical models. The antidote for this is to stay close to the empirical evidence.

My good friend Dr. Andrew Beckwith (Prof., Chongqing University, China) explains that there are axiomatic problems with the Alcubierre-type warp drive theory. Basically the implied axioms (or starting assumptions of the mathematics) requires a multiverse universe or multiple universes, but the mathematics is based on a single universe. Thus even though the mathematics appears to be sound its axioms are contradictory to this mathematics. As Dr. Beckwith states, “reducto ad absurdum”. For now, this unfortunately means that there is no such thing as a valid warp drive theory. LFT prevents this.

For a discussion of other problems in physical theories please see my peer reviewed 2013 paper “New Evidence, Conditions, Instruments & Experiments for Gravitational Theories” published in the Journal of Modern Physics. In this paper I explain how General Relativity can be used to propose some very strange ideas, and therefore, claiming that something is consistent with General Relativity does not always lead to sensible outcomes.

The question we should be asking is not, can we travel faster than light (FTL) but how do we bypass LFT? Or our focus should not be how to travel but how to effect destination arrival.

Let us take one step back. Since Einstein, physicists have been working on a theory of everything (TOE). Logic dictates that for a true TOE, the TOE must be able to propose from first principles, why conservation of mass-energy and conservation of momentum hold. If these theories cannot, they cannot be TOEs. Unfortunately all existing TOEs have these conservation laws as their starting axioms, and therefore, are not true TOEs. The importance of this requirement is that if we cannot explain why conservation of momentum is true, like Einstein did with LFT, how do we know how to apply this in developing interstellar propulsion engines? Yes, we have to be that picky, else we will be throwing millions if not billions of dollars in funding into something that probably won’t work in practice.

Is a new physics required to achieve interstellar propulsion? Does a new physics exists?

In 2007, after extensive numerical modeling I discovered the massless formula for gravitational acceleration, g=τc^2, where tau τ is the change in the time dilation transformation (dimensionless LFT) divided by that distance. (The error in the modeled gravitational acceleration is less than 6 parts per million). Thereby, proving that mass is not required for gravitational theories and falsifying the RSQ (Relativity, String & Quantum) theories on gravity. There are two important consequences of this finding, (1) we now have a new propulsion equation, and (2) legacy or old physics cannot deliver.

But gravity modification per g=τc^2 is still based on motion, and therefore, constrained by LFT. That is, gravity modification cannot provide for interstellar propulsion. For that we require a different approach, the new physics.

At least from the perspective of propulsion physics, having a theoretical approach for a single formula g=τc^2 would not satisfy the legacy physics community that a new physics is warranted or even exists. Therefore, based on my 16 years of research involving extensive numerical modeling with the known empirical data, in 2014, I wrote six papers laying down the foundations of this new physics:

1. “A Universal Approach to Forces”: There is a 4th approach to forces that is not based on Relativity, String or Quantum (RSQ) theories.
2. “The Variable Isotopic Gravitational Constant”: The Gravitational Constant G is not a constant, and independent of mass, therefore gravity modification without particle physics is feasible.
3. “A Non Standard Model Nucleon/Nuclei Structure”: Falsifies the Standard Model and proposes Variable Electric Permittivity (VEP) matter.
4. “Replacing Schrödinger”: Proposes that the Schrödinger wave function is a good but not an exact model.
5. “Particle Structure”: Proposes that the Standard Model be replaced with the Component Standard Model.
6. “Spectrum Independence”: Proposes that photons are spectrum independent, and how to accelerate nanowire technology development.

This work, published under the title Super Physics for Super Technologies is available for all to review, critique and test its validity. (A non-intellectual emotional gut response is not a valid criticism). That is, the new physics does exist. And the relevant outcome per interstellar propulsion is that subspace exists, and this is how Nature implements probabilities. Note, neither quantum nor string theories ask the question, how does Nature implement probabilities? And therefore, are unable to provide an answer. The proof of subspace can be found in how the photon electromagnetic energy is conserved inside the photon.

Subspace is probabilistic and therefore does not have the time dimension. In other words destination arrival is not LFT constrained by motion based travel, but is effected by probabilistic localization. We therefore, have to figure out navigation in subspace or vectoring and modulation. Vectoring is the ability to determine direction, and modulation is the ability to determine distance. This approach is new and has an enormous potential of being realized as it is not constrained by LFT.

Yes, interstellar propulsion is feasible, but not as of the warp drives we understand today. As of 2012, there are only about 50 of us on this planet working or worked towards solving the gravity modification and interstellar propulsion challenge.

So the question is not, whether gravity modification or interstellar propulsion is feasible, but will we be the first nation to invent this future?

Small gadgets such as smart watches can be frustrating to use because their tiny buttons and touch screens are tricky to operate. Google has two possible solutions for the fat finger problem: control your gadgets by subtly rubbing your finger and thumb together, or by swiping a grid of conductive yarn woven into your clothing.

The first of those two ideas works thanks to a tiny radar sensor that could be integrated into, say, a smart watch and can detect fine motions of your hands from a distance and even through clothing. Levi Strauss announced today that it is working with Google to integrate fabric touch panels into its clothing designs. The new projects were announced at Google’s annual developer conference in San Francisco Friday by Ivan Poupyrev, a technical program lead in Google’s Advanced Technology and Projects research group.

Until 2006 our Solar System consisted essentially of a star, planets, moons, and very much smaller bodies known as asteroids and comets. In 2006 the International Astronomical Union’s (IAU) Division III Working Committee addressed scientific issues and the Planet Definition Committee address cultural and social issues with regard to planet classifications. They introduced the “pluton” for bodies similar to planets but much smaller.

The IAU set down three rules to differentiate between planets and dwarf planets. First, the object must be in orbit around a star, while not being itself a star. Second, the object must be large enough (or more technically correct, massive enough) for its own gravity to pull it into a nearly spherical shape. The shape of objects with mass above 5×1020 kg and diameter greater than 800 km would normally be determined by self-gravity, but all borderline cases would have to be established by observation.

Third, plutons or dwarf planets, are distinguished from classical planets in that they reside in orbits around the Sun that take longer than 200 years to complete (i.e. they orbit beyond Neptune). Plutons typically have orbits with a large orbital inclination and a large eccentricity (noncircular orbits). A planet should dominate its zone, either gravitationally, or in its size distribution. That is, the definition of “planet” should also include the requirement that it has cleared its orbital zone. Of course this third requirement automatically implies the second. Thus, one notes that planets and plutons are differentiated by the third requirement.

As we are soon to become a space faring civilization, we should rethink these cultural and social issues, differently, by subtraction or addition. By subtraction, if one breaks the other requirements? Comets and asteroids break the second requirement that the object must be large enough. Breaking the first requirement, which the IAU chose not address at the time, would have planet sized bodies not orbiting a star. From a socio-cultural perspective, one could suggest that these be named “darktons” (from dark + plutons). “Dark” because without orbiting a star, these objects would not be easily visible; “tons” because in deep space, without much matter, these bodies could not meet the third requirement of being able to dominate its zone.

Taking this socio-cultural exploration a step further, by addition, a fourth requirement is that of life sustaining planets. The scientific evidence suggest that life sustaining bodies would be planet-sized to facilitate a stable atmosphere. Thus, a life sustaining planet would be named “zoeton” from the Greek zoe for life. For example Earth is a zoeton while Mars may have been.

Again by addition, one could define, from the Latin aurum for gold, “auton”, as a heavenly body, comets, asteroids, plutons and planets, whose primary value is that of mineral or mining interest. Therefore, Jupiter is not a zoeton, but could be an auton if one extracts hydrogen or helium from this planet. Another auton is 55 Cancri e, a planet 40 light years away, for mining diamonds with an estimated worth of $26.9x1030. The Earth is both a zoeton and an auton, as it both, sustains life and has substantial mining interests, respectively. Not all plutons or planets could be autons. For example Pluto would be too cold and frozen for mining to be economical, and therefore, frozen darktons would most likely not be autons.

At that time the IAU also did not address the upper limit for a planet’s mass or size. Not restricting ourselves to planetary science would widen our socio-cultural exploration. A social consideration would be the maximum gravitational pull that a human civilization could survive, sustain and flourish in. For example, for discussion sake, a gravitational pull greater the 2x Earth’s or 2g, could be considered the upper limit. Therefore, planets with larger gravitational pulls than 2g would be named “kytons” from the Antikythera mechanical computer as only machines could survive and sustain such harsh conditions over long periods of time. Jupiter would be an example of such a kyton.

Are there any bodies between the gaseous planet Jupiter and brown dwarfs? Yes, they have been named Y-dwarfs. NASA found one with a surface temperature of only 80 degrees Fahrenheit, just below that of a human. It is possible these Y-dwarfs could be kytons and autons as a relatively safe (compared to stars) source of hydrogen.

Taking a different turn, to complete the space faring vocabulary, one can redefine transportation by their order of magnitudes. Atmospheric transportation, whether for combustion intake or winged flight can be termed, “atmosmax” from “atmosphere”, and Greek “amaxi” for car or vehicle. Any vehicle that is bound by the distances of the solar system but does not require an atmosphere would be a “solarmax”. Any vehicle that is capable of interstellar travel would be a “starship”. And one capable of intergalactic travel would be a “galactica”.

We now have socio-cultural handles to be a space faring civilization. A vocabulary that facilitates a common understanding and usage. Exploration implies discovery. Discovery means new ideas to tackle new environments, new situations and new rules. This can only lead to positive outcomes. Positive outcomes means new wealth, new investments and new jobs. Let’s go forth and add to these cultural handles.
