The Kline Directive: Technological Feasibility (2e)

Posted by in categories: cosmology, defense, engineering, general relativity, particle physics, philosophy, physics, scientific freedom, space

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, 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 …”

The Kline Directive: Technological Feasibility (2d)

Posted by in categories: cosmology, defense, education, engineering, general relativity, particle physics, philosophy, physics, policy, space

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, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationships, and Technological Feasibility.

In this post on technological feasibility, I point to some more mistakes in physics, so that we are aware of the type of mistakes we are making. This I hope will facilitate the changes required of our understanding of the physics of the Universe and thereby speed up the discovery of new physics required for interstellar travel.

The scientific community recognizes two alternative models for force. Note I use the term recognizes because that is how science progresses. This is necessarily different from the concept how Nature operates or Nature’s method of operation. Nature has a method of operating that is consistent with all Nature’s phenomena, known and unknown.

If we are willing to admit, that we don’t know all of Nature’s phenomena — our knowledge is incomplete — then it is only logical that our recognition of Nature’s method of operation is always incomplete. Therefore, scientists propose theories on Nature’s methods, and as science progresses we revise our theories. This leads to the inference that our theories can never be the exact presentation of Nature’s methods, because our knowledge is incomplete. However, we can come close but we can never be sure ‘we got it’.

…here’s Tom with the Weather.
That right there is comedian/philosopher Bill Hicks, sadly no longer with us. One imagines he would be pleased and completely unsurprised to learn that serious scientific minds are considering and actually finding support for the theory that our reality could be a kind of simulation. That means, for example, a string of daisy-chained IBM Super-Deep-Blue Gene Quantum Watson computers from 2042 could be running a History of the Universe program, and depending on your solipsistic preferences, either you are or we are the character(s).

It’s been in the news a lot of late, but — no way, right?

Because dude, I’m totally real
Despite being utterly unable to even begin thinking about how to consider what real even means, the everyday average rational person would probably assign this to the sovereign realm of unemployable philosophy majors or under the Whatever, Who Cares? or Oh, That’s Interesting I Gotta Go Now! categories. Okay fine, but on the other side of the intellectual coin, vis-à-vis recent technological advancement, of late it’s actually being seriously considered by serious people using big words they’ve learned at endless college whilst collecting letters after their names and doin’ research and writin’ and gettin’ association memberships and such.

So… why now?

The Kline Directive: Theoretical-Empirical Relationship (Part 4)

Posted by in categories: business, cosmology, defense, economics, education, engineering, nuclear weapons, particle physics, philosophy, physics, policy, scientific freedom, space

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, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationship, & Technological Feasibility.

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)

Propulsion Mechanism Relatively Safe? Theoretical-Empirical Relationship?
Conventional Fuel Rockets: Yes, but susceptible to human error. Known. Theoretical foundations are based on Engineering Feasible Theories, and have been evolving since Robert Goddard invented the first liquid-fueled rocket in 1926.
Antimatter Propulsion: No. Extensive gamma ray production (Carl Sagan). Issue is how does one protect the Earth? Capable of an End of Humanity (EOH) event. Dependent on Millennium Theories. John Eades states in no uncertain terms that antimatter is impossible to handle and create.
Atomic Bomb Pulse Detonation: No, because (Project Orion) one needs to be able to manage between 300,000 and 30,000,000 atomic bombs per trip. Known and based on Engineering Feasible Theories.
Time Travel: Do Not Know. Depends on how safely exotic matter can be contained. Dependent on a Millennium Theory. Exotic matter hypotheses are untested. No experimental evidence to show that Nature allows for a breakdown in causality.
String / Quantum Foam Based Propulsion: Do Not Know. Depends on how safely exotic matter can be contained. Dependent on a Millennium Theory. String theories have not been experimentally verified. Exotic matter hypotheses are untested. Existence of Quantum Foam now suspect (Robert Nemiroff).
Small Black Hole Propulsion: No. Capable of an End Of Humanity (EOH) event Don’t know if small black holes really do exist in Nature. Their theoretical basis should be considered a Millennium Theory.

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.

The Kline Directive: Theoretical-Empirical Relationship (Part 3)

Posted by in categories: cosmology, defense, education, engineering, particle physics, philosophy, physics, policy, space

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.

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:

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 Kline Directive: Theoretical-Empirical Relationship (Part 1)

Posted by in categories: business, cosmology, defense, economics, education, engineering, events, finance, human trajectories, particle physics, philosophy, physics, policy

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.

In Part 1 of this post I will explore Theoretical-Empirical Relationship. Not theoretical relationships, not empirical relationships but theoretical-empirical relationships. To do this let us remind ourselves what the late Prof. Morris Kline was getting at in his book Mathematics: The Loss of Certainty, 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.

History of science shows that all three giants of science of their times, Robert Boyle, Isaac Newton & Christiaan Huygens believed that light traveled in aether medium, but by the end of the 19th century there was enough experimental evidence to show aether could not be a valid concept. The primary experiment that changed our understanding of aether was the Michelson–Morley experiment of 1887, which once and for all proved that aether did not have the correct properties as the medium in which light travels.

The Kline Directive: Safety Awareness

In this post I will explore Safety Awareness.

In the heady rush to propose academically acceptable ideas about new propulsions systems or star drives it is very easy to overlook safety considerations. The eminent cosmologist Carl Sagan said it best “So the problem is not to shield the payload, the problem is to shield the earth” (Planet. Space Sci., pp. 485 – 498, 1963)

On Leaving the Earth. Like, Forever. Bye-Bye.

Technology is as Human Does

When one of the U.S. Air Force’s top future strategy guys starts dorking out on how we’ve gotta at least begin considering what to do when a progressively decaying yet apocalyptically belligerent sun begins BBQing the earth, attention is payed. See, none of the proposed solutions involve marinade or species-level acquiescence, they involve practical discussion on the necessity for super awesome technology on par with a Kardeshev Type II civilization (one that’s harnessed the energy of an entire solar system).

Because Not if, but WHEN the Earth Dies, What’s Next for Us?
Head over to Kurzweil AI and have a read of Lt. Col. Peter Garretson’s guest piece. There’s perpetuation of the species stuff, singularity stuff, transhumanism stuff, space stuff, Mind Children stuff, and plenty else to occupy those of us with borderline pathological tech obsessions.

The Truth about Space Travel is Stranger than Fiction

I have been corresponding with John Hunt and have decided that perhaps it is time to start moving toward forming a group that can accomplish something.

The recent death of Neil Armstrong has people thinking about space. The explosion of a meteor over Britain and the curiosity rover on Mars are also in the news. But there is really nothing new under the sun. There is nothing that will hold people’s attention for very long outside of their own immediate comfort and basic needs. Money is the central idea of our civilization and everything else is soon forgotten. But this idea of money as the center of all activity is a death sentence. Human beings die and species eventually become extinct just as worlds and suns also are destroyed or burn out. Each of us is in the position of a circus freak on death row. Bizarre, self centered, doomed; a cosmic joke. Of all the creatures on this planet, we are the freaks the other creatures would come to mock- if they were like us. If they were supposedly intelligent like us. But are we actually the intelligent ones? The argument can be made that we lack a necessary characteristic to be considered truly intelligent life forms.

Truly intelligent creatures would be struggling with three problems if they found themselves in our situation as human beings on Earth in the first decades of this 21st century;

1. Mortality. With technology possible to delay death and eventually reverse the aging process, intelligent beings would be directing the balance of planetary resources towards conquering “natural” death.
