In 2014, I submitted my paper “A Universal Approach to Forces” to the journal Foundations of Physics. The 1999 Noble Laureate, Prof. Gerardus ‘t Hooft, editor of this journal, had suggested that I submit this paper to the journal Physics Essays.

My previous 2009 submission “Gravitational acceleration without mass and noninertia fields” to Physics Essays, had taken 1.5 years to review and be accepted. Therefore, I decided against Prof. Gerardus ‘t Hooft’s recommendation as I estimated that the entire 6 papers (now published as Super Physics for Super Technologies) would take up to 10 years and/or $20,000 to publish in peer reviewed journals.

Prof. Gerardus ‘t Hooft had brought up something interesting in his 2008 paper “A locally finite model for gravity” that “… absence of matter now no longer guarantees local flatness…” meaning that accelerations can be present in spacetime without the presence of mass. Wow! Isn’t this a precursor to propulsion physics, or the ability to modify spacetime without the use of mass?

As far as I could determine, he didn’t pursue this from the perspective of propulsion physics. A year earlier in 2007, I had just discovered the massless formula for gravitational acceleration g=τc^2, published in the Physics Essays paper referred above. In effect, g=τc^2 was the mathematical solution to Prof. Gerardus ‘t Hooft’s “… absence of matter now no longer guarantees local flatness…”

Prof. Gerardus ‘t Hooft used string theory to arrive at his inference. Could he empirically prove it? No, not with strings. It took a different approach, numerical modeling within the context of Einstein’s Special Theory of Relativity (STR) to derive a mathematic solution to Prof. Gerardus ‘t Hooft’s inference.

In 2013, I attended Dr. Brian Greens’s Gamow Memorial Lecture, held at the University of Colorado Boulder. If I had heard him correctly, the number of strings or string states being discovered has been increasing, and were now in the 10500 range.

I find these two encounters telling. While not rigorously proved, I infer that (i) string theories are unable to take us down a path the can be empirically proven, and (ii) they are opened ended i.e. they can be used to propose any specific set of outcomes based on any specific set of inputs. The problem with this is that you now have to find a theory for why a specific set of inputs. I would have thought that this would be heartbreaking for theoretical physicists.

In 2013, I presented the paper “Empirical Evidence Suggest A Need For A Different Gravitational Theory,” at the American Physical Society’s April conference held in Denver, CO. There I met some young physicists and asked them about working on gravity modification. One of them summarized it very well, “Do you want me to commit career suicide?” This explains why many of our young physicists continue to seek employment in the field of string theories where unfortunately, the hope of empirically testable findings, i.e. winning the Noble Prize, are next to nothing.

I think string theories are wrong.

Two transformations or contractions are present with motion, Lorentz-FitzGerald Transformation (LFT) in linear motion and Newtonian Gravitational Transformations (NGT) in gravitational fields.

The fundamental assumption or axiom of strings is that they expand when their energy (velocity) increases. This axiom (let’s name it the Tidal Axiom) appears to have its origins in tidal gravity attributed to Prof. Roger Penrose. That is, macro bodies elongate as the body falls into a gravitational field. To be consistent with NGT the atoms and elementary particles would contract in the direction of this fall. However, to be consistent with tidal gravity’s elongation, the distances between atoms in this macro body would increase at a rate consistent with the acceleration and velocities experienced by the various parts of this macro body. That is, as the atoms get flatter, the distances apart get longer. Therefore, for a string to be consistent with LFT and NGT it would have to contract, not expand. One suspects that this Tidal Axiom’s inconsistency with LFT and NGT has led to an explosion of string theories, each trying to explain Nature with no joy. See my peer-reviewed 2013 paper New Evidence, Conditions, Instruments & Experiments for Gravitational Theories published in the Journal of Modern Physics, for more.

The vindication of this contraction is the discovery of the massless formula for gravitational acceleration g=τc^2 using Newtonian Gravitational Transformations (NGT) to contract an elementary particle in a gravitational field. Neither quantum nor string theories have been able to achieve this, as quantum theories require point-like inelastic particles, while strings expand.

What worries me is that it takes about 70 to 100 years for a theory to evolve into commercially viable consumer products. Laser are good examples. So, if we are tying up our brightest scientific minds with theories that cannot lead to empirical validations, can we be the primary technological superpower a 100 years from now?

The massless formula for gravitational acceleration g=τc^2, shows us that new theories on gravity and force fields will be similar to General Relativity, which is only a gravity theory. The mass source in these new theories will be replaced by field and particle motions, not mass or momentum exchange. See my Journal of Modern Physics paper referred above on how to approach this and Super Physics for Super Technologies on how to accomplish this.

Therefore, given that the primary axiom, the Tidal Axiom, of string theories is incorrect it is vital that we recognize that any mathematical work derived from string theories is invalidated. And given that string theories are particle based theories, this mathematical work is not transferable to the new relativity type force field theories.

I forecast that both string and quantum gravity theories will be dead by 2017.

When I was seeking funding for my work, I looked at the Broad Agency Announcements (BAAs) for a category that includes gravity modification or interstellar propulsion. To my surprise, I could not find this category in any of our research organizations, including DARPA, NASA, National Science Foundation (NSF), Air Force Research Lab, Naval Research Lab, Sandia National Lab or the Missile Defense Agency.

So what are we going to do when our young graduates do not want to or cannot be employed in string theory disciplines?

(Originally published in the Huffington Post)

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?

(Originally published in the Huffington Post)

OK, why do we need a different technology to achieve commercial viability (as in mass space tourism) for either interplanetary or interstellar travel?

In many of my previous posts I had shown that all the currently proposed technologies or technologies to be, are either phenomenally expensive (on the order of several multiples of World GDP), bordering on the impossible or just plain conjecture. This is very unfortunate, as I was hoping that some of the proposals would at least appear realistic, but no joy. I feel very sorry for those who are funding these projects. For a refresher I have posted an updated version of the Interstellar Challenge Matrix (ICM) here which documents 5 of the 11 inconsistencies in modern physics. I give permission to my readers to use this material for non-commercial or academic uses.

I recently completed the 12-year study into the theoretical & technological feasibility of gravity modification published under the title An Introduction to Gravity Modification, 2nd Edition. For the very first time we now have a scientific definition for gravity modification:

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 that this definition specifically states “without the use of mass”, for obvious reasons – for example it does not make sense to carry around the mass of a planet to propel 7 astronauts, does it?

By this definition alone, we have eliminated all three status quo theories – general relativity, quantum gravity and string theories. Therefore, the urgent need to construct a new theory that will facilitate the development of gravity modification technologies.

And further, by this definition we know the additional requirements of such a new theory. The theory should show us, firstly, how to attenuate or amplify the gravitational field strength, and secondly, how to change the direction of this force field – all without using mass.

To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationships, and Technological Feasibility.

In this post I explain two more mistakes in physics. The first is 55 years old, and should have been caught long ago.

Bondi, in his 1957 paper “Negative mass in General Relativity”, had suggested that mass could be negative and there are surprising results from this possibility. I quote,

“… the positive body will attract the negative one (since all bodies are attracted by it), while the negative body will repel the positive body (since all bodies are repelled by it). If the motion is confined to the line of centers, then one would expect the pair to move off with uniform acceleration …”

As a theoretician Bondi required that the motion be “confined to the line of centers” or be confined to a straight line. However, as experimental physicist we would take a quantity of negative mass and another quantity of positive mass and place them in special containers attached two spokes. These spokes form a small arc at one end and fixed to the axis of a generator at the other end. Let go, and watch Bondi’s uniform straight line acceleration be translated into circular motion driving a generator. Low and behold, we have a perpetual motion machine generating free electricity!

Wow! A perpetual motion machine hiding in plain sight in the respectable physics literature, and nobody caught it. What is really bad about this is that Einstein’s General Relativity allows for this type of physics, and therefore in General Relativity this is real. So was Bondi wrong or does General Relativity permit perpetual motion physics? If Bondi is wrong then could Alcubierre too be wrong as his metrics requires negative mass?

Perpetual motion is sacrilege in contemporary physics, and therefore negative mass could not exist. Therefore negative mass is in the realm of mathematical conjecture. What really surprised me was the General Relativity allows for negative mass, at least Bondi’s treatment of General Relativity.

This raises the question, what other problems in contemporary physics do we have hiding in plain sight?

There are two types of exotic matter, that I know of, the first is negative mass per Bondi (above) and the second is imaginary (square root of −1) mass. The recent flurry of activity of the possibility that some European physicists had observed FTL (faster than light) neutrinos, should also teach us some lessons.

If a particle is traveling faster than light its mass becomes imaginary. This means that these particles could not be detected by ordinary, plain and simple mass based instruments. So what were these physicists thinking? That somehow Lorentz-Fitzgerald transformations were no longer valid? That mass would not convert into imaginary matter at FTL? It turned out that their measurements were incorrect. Just goes to show how difficult experimental physics can get, and these experimental physicists are not given the recognition due to them for the degree of difficulty of their work.

So what type of exotic matter was Dr. Harold White of NASA’s In-Space Propulsion program proposing in his presentation at the 2012 100-Year Starship Symposium? Both Alcubierre and White require exotic matter. Specifically, Bondi’s negative mass. But I’ve shown that negative mass cannot exist as it results in perpetual motion machines. Inference? We know that this is not technologically feasible.

That is, any hypothesis that requires exotic negative mass cannot be correct. This includes time travel.

To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationships, and Technological Feasibility.

In this post I discuss three concepts, that if implemented should speed up the rate of innovation and discovery so that we can achieve interstellar travel within a time frame of decades, not centuries.

Okay, what I’m going to say will upset some physicists, but I need to say it because we need to resolve some issues in physics to distinguish between mathematical construction and conjecture. Once we are on the road to mathematical construction, there is hope that this will eventually lead to technological feasibility. This post is taken from my published paper “Gravitational Acceleration Without Mass And Noninertia Fields” in the peer reviewed AIP journal, Physics Essays, and from my book An Introduction to Gravity Modification.

The Universe is much more consistent than most of us (even physicists) suspect. Therefore, we can use this consistency to weed out mathematical conjecture from our collection of physical hypotheses. There are two set of transformations that are observable. The first, in a gravitational field at a point where acceleration is a compared to a location at 0 an infinite distance from the gravitational source, there exists Non-Linear transformations Γ(a) which states that time dilation ta/t0, length contraction x0/xa, and mass increase ma/m0, behave in a consistent manner such that:

(1)

.

The second consistency is Lorentz-Fitzgerald transformations Γ(v) which states that at a velocity v compared to rest at 0, time dilation tv/t0, length contraction x0/xv, and mass increase mv/m0, behave in a consistent manner such that:

(2)

.

Now here is the surprise. The Universe is so consistent that if we use the Non-Linear transformation, equation (1) to calculate the free fall velocity (from infinity) to a certain height above the planet’s or star’s surface, and it’s corresponding time dilation, we find that it is exactly what the Lorentz-Fitzgerald transformation, equation (2) requires. That there is this previously undiscovered second level of consistency!

You won’t find this discovery in any physics text book. Not yet anyway. I published this in my 2011 AIP peer reviewed Physics Essays paper, “Gravitational Acceleration Without Mass And Noninertia Fields”.

Now let us think about this for a moment. What this says is that the Universe is so consistent that the linear velocity-time dilation relationship must be observable where ever velocity and time dilation is present, even in non-linear spacetime relationships where acceleration is present and altering the velocity and therefore the time dilation present.

Or to put it differently, where ever Γ(a) is present the space, time, velocity and acceleration relationship must allow for Γ(v) to be present in a correct and consistent manner. When I discovered this I said, wow! Why? Because we now have a means of differentiating hypothetical-theoretical gravitational fields, and therefore mathematical conjectures, from natural-theoretical gravitational fields, which are correct mathematical constructions.

That is, we can test the various quantum gravity & string hypotheses and any of the tensor metrics! Einstein’s tensor metrics should be correct, but from a propulsion perspective there is something more interesting, Alcubierre tensor metrics. Alcubierre was the first, using General Relativity, to propose the theoretical possibility of warp speed (note, not how to engineer it). Alcubierre’s work is very sophisticated. However, the concept is elegantly simple. That one can wrap a space craft in gravitational-type deformed spacetime to get it to ‘fall’ in the direction of travel.

The concept suggest that both equations (1) and (2) are no longer valid as the relative velocity between the outer edges of the spacetime wrap and an external observer is either at c, the velocity of light or greater – one needs to do the math to get the correct answer. Even at an acceleration of 1g, and assuming that this craft has eventually reached c, equation (1) and (2) are no longer consistent. Therefore, my inference is that Alcubierre metrics allows for zero time dilation within the wrap but not velocities greater than the velocity of light. Therefore, it is also doubtful that Dr. Richard Obousy hypothesis that it is possible to achieve velocities of 1E30c with a quantum string version of Alcubierre warp drive is correct.

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, 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. 5. Technological Feasibility.

From Part 1 … “that mathematics has become so sophisticated and so very successful that it can now be used to prove anything and everything, and therefore, the loss of certainty that mathematics will provide reasonability in guidance and correctness in answers to our questions in the sciences”.

We need to note that there are several different relationships between the mathematics of physics and the physics of the real world.

The first relationship and most common type is that several different types of equations in physics describe the same physics of the world. Gravity is a great example. The three mathematical theories on gravity are relativity, quantum and string theories. All three model the same single physical phenomenon, gravitational fields. So if one is correct than the other two must be wrong. All three cannot be correct. So which is it?

Just for argument sake, there is another alternative — all three are wrong. But wait didn’t all those experiments and observations prove that General Relativity is correct? Remember for argument’s sake, that proving that something fits the experimental observation does not mean that is how Nature works. That is why theoretical physicists spend so much time, money and effort considering alternatives like quantum and string theories.

The second relationship is that different mathematical descriptions can be ascribed to different parts of a physical phenomenon. For example Einstein’s General Relativity describes spacetime as tensor calculus, a very complex mathematical model which he did not get right on his first attempt. General Relativity addresses the question of gravity’s source as an energy-momentum tensor. To put it simply, these equations are complex.

Whereas in my work I realized at some point during my investigation into gravity modification, that to develop technologies that could modify gravity we needed a mathematical equation (g=τc2) that would describe the phenomenon of gravitational acceleration without needing to include mass. I discovered this equation, g=τc2, after very extensive numerical modeling of gravitational accelerations in spacetime, where tau, τ is the change in time dilation divided by change in distance (for more look up my Physics Essays paper, “Gravitational Acceleration Without Mass And Noninertia Fields”). Consider how elegantly simple this equation is and without mass we can now replace the source with something more technology friendly.

And the third type of relationship is the mathematics of physics that cannot or cannot yet be verified with experimental evidence. String theories are great examples of this. From what I know, there is nothing in the string theories (which have not been borrowed for quantum mechanics) that is experimentally verifiable. And yet we go on. Why?

Consider this. The experimental evidence proves that nothing with mass can be accelerated past the velocity of light (aka Lorentz-Fitzgerald transformations), and yet Dr. Eric Davis agrees with Dr. Richard Obousy that using string quantum theory that the maximum velocity one can reach is 1032 x c (100,000,000,000,000,000,000,000,000,000,000 x velocity of light). Now what would you believe, experimental evidence or mathematical conjecture?

Now, do you agree that that mathematics has become so sophisticated and so very successful that it can be used to prove anything and everything, and therefore, the loss of certainty that mathematics can provide reasonability in guidance and correctness in answers to our questions in the sciences?

Don’t get me wrong. Mathematics is vital for the progress of the sciences, but it needs to be tempered with real world experimental evidence, otherwise it is just conjecture, and retards our search for interstellar travel technologies.

This video was broadcast on G4TV, September 19th 2012.

http://www.g4tv.com/videos/60838/dr-eric-w-davis-on-new-light-speed-breaking-science/

Major Notes from the Video are:

a. Dr. Eric Davis, Senior Research Physicist at the Institute for Advanced Studies, Austin TX.

b. Use exotic energy, quantum energy from vacuum energy, to generate warp drive by surfing space.

c. Surfing on space at faster than the velocity of light.

d. Theory requires stupendous amount of vacuum energy.

e. Sonny White (correct name?) suggests that it could be done with much less energy.

f. Disruptive innovations can happen at any time.

g. Richard Obousy of Icarus Interstellar Inc, using string quantum theory shows that the limit of velocity is 10E32 x c (velocity of light) using quantum string theories.

——-

Need to bear in mind that for interstellar travel to become a reality three factors must be realized.

1) Costs:

From the video this group has not been able to quantify their costs.

2) Technological Feasibility:

As Dr Eric Davis states it might take anywhere from a 100 year to 200 years for this technology to become a reality, but you never know that some disruptive innovation might change all that.

There is another problem with this. Dr. Robert Nemiroff’s Three Photon Observation, which suggests that quantum foam may not exists, therefore falsifying the ability to do interstellar travel in this manner.

Actually come to think about Dr. Eric Davis was describing Dr. Miguel Alcubierre work but substituting Alcubierre’s General Relativity tensors solutions with ‘string quantum’ theory.

3) Safety: Don’t know how to navigate or how to protect crew.

That is a fail on all three counts.

Finally, if I remember correctly, the string theories sits on top of quantum theory and therefore all the discoveries in quantum theory have been translated into string theories. But the string theories by themselves have not been able to predict any new physical behavior, in an ‘a priori’ manner.

For a simple description of quantum foam and vacuum energy see, here.

——-

I put forward a test for these type of proposals, in the comments section of an earlier posting,

https://lifeboat.com/blog/2012/10/debunking-antimatter-rockets-for-interstellar-travel

And here it is, if you had a few millions dollars can you demonstrate experimental feasibility as a propulsion device?

If the answer is ‘no’ then it is debunked if it is ‘yes’ then let’s get the funding. From Dr Eric Davis comments it is clear that the answer is ‘no’.

Appreciate your comments & feedback.
