The Cosmic-Rays-versus-White-Dwarfs Safety Argument

Posted by in categories: existential risks, particle physics

Tom Kerwick challenged my warnings by claiming that the observed longevity of white dwarfs, in spite of the constant bombardment by cosmic rays, provides a convincing safety argument regarding the currently running nuclear collisions experiment at CERN. This claim is important but, unfortunately, inconclusive as I shall try to demonstrate.

It is true that the collisions performed at CERN are relatively meager compared to cosmic-ray energies. The current, approximately 10 TeV collisions between equal-momentum particles at CERN correspond to 10.000 TeV cosmic ray protons hitting a stationary proton on earth or a white dwarf. The thousand-fold increase is a consequence of the relativistic energy-momentum law being applicable.

If 10.000 TeV (= 10 to the 16 electron volt) look like much, cosmic ray energies up to 10 to the 22 electron volt (a million times more) have been measured. However, if the latter are translated back into symmetric collisions of the CERN type, they are “only” a thousand times more energetic than CERN’s (owing to the square-root rule implicit in the mentioned law).

The fact that white dwarfs appear to be resilient to this bombardment is living proof that the cross section of CERN-generated miniature black holes (as well as their up to a thousand times more massive cosmic-ray generated analogs) must be minuscule. Specifically, their diameter must lie below that of a lepton (electron or quark). While an electron’s diameter is often supposed to be zero, neutrino absorption in solid matter yields a finite value (about ten to the negative 24 meter). In addition, the Telemach theorem guarantees a non-zero electron diameter.

Real Scientist Working in the Field of Propulsion Physics

Posted by in categories: physics, space

While emailing back and forth with Ron Kita, I realized that it would be useful to compile a list of researchers who have published serious papers, past & present, in the new field of propulsion physics (gravity modification is an example) at least for the purpose of finding out how many countries are at some stage in this field.

This is important to do if we are to hasten the theoretical & technological development to leave Earth on a commercially feasible scale. I was surprised by what I found.

Below is the list. I’m sure it is not complete but it is a start. If you know of anyone who should be on this list, please let me know, and I will update this post.

Here are the ground rules for including a name.

Ownership of Archieved Tweets

Posted by in category: economics

- From Integrationalism

In April of 2010 the Library of Congress announced that it will acquire all of the public tweets for future generations to review. It’s quite the ambitious effort from a technological standpoint, considering all of the data migration and storage as the micro-blogging social network grows. The initiative also has some uncovered ethical and democratic potential that are currently being overlooked.

Twitter as a platform is empowering the creators of the world to understand how their co-conspirers and consumers are affecting the discovery, development, and delivery of new goods & services to be brought to market. For instance, Marketing and other R&D departments across the globe at the enterprise scale are using social networks like Twitter to monitor and improve their CRM (Customer Relationship Management) processes. These aren’t rigid customer service initiatives, but also customer discovery initiatives. Social networking is giving new meaning to the idea that supply & demand are never ending sphere of interaction; further, confusing the philosophical ideal of who might our creators and consumers be.

Expect Confirmation of Extraterrestrial Life by 2047

Posted by in categories: cosmology, policy, space

Recently Seth Shostak of the SETI Institute, wrote an article in the Huffington Post How to Find Extraterrestrial Life. He had proposed that the search for extraterrestrial life was a three-way horse race. According to Shostak:

(1) Discover Life Nearby: This is the search for life in our solar system.

(2) Sniff It Out: Do the sort of spectral analysis that might detect atmospheric gases caused by biology.

(3) Eavesdrop On ET: Otherwise known as SETI, is the effort to detect radio signals or laser flashes from technically savvy extraterrestrials.

Jesse Bering Wrote an important Article in July’s Scientific American (“The Rat that Laughed”)

Posted by in categories: existential risks, particle physics

In it he reports on a gorilla in a cage who could be brought to phrenetic laughter by his human friend’s pretending to bite him into his toe. Quote: “If you have never seen a gorilla in a fit of laughter, I recommend searching out such a sight before you pass from this world.”

This is absolutely human behavior. If you know about the cross-caring theory, which explains how a young child interacting with his bonding partner is getting “moved” into suspecting benevolence shown towards him, then you realize that the same thing can be accomplished with a caged or non-caged gorilla.

I recently mentioned Margaret Howe, a pupil of my late friend Gregory Bateson’s. There are important insights about the mission of humankind on our planet and beyond (“galactic export”) that would make it a great pity if this “second level of human social evolution on earth and in the solar system” was going to be clipped.

I know I am being impossible, but finding outrageous things that tickle everyone in her or his heart so as to be moved is the real mission of science. I fantasize talking with a gorilla – or orangutan – about the long-stretched “toe” of the visualized Schwarzschild metric of a black hole, both of us laughing.

I Thank the Planet for Tolerating my Warnings without Panicking

Posted by in categories: existential risks, particle physics

http://www.aljazeera.com/programmes/insidestory/2012/07/2012759585764599.html (at minutes 09:00–10:10, 11:00–12:03, 12:35–13:25, 16:08–17:13) gave me a world-wide forum again. The rest of the media and all colleagues of mine keep their mouths shut.

There is logic behind this schizophrenic world-wide attitude: In case the outlaw is right, one can later always claim that not the whole planet was part of the conspiracy of silence since one high-ranking international outlet reported. However, this strategy is not logical. For if I am right and the worst case materializes, the fig leaf will go under as well.

My class yesterday in which this riddle was touched upon in passing helped me see the mechanism: My results on black holes are too much advanced from the planet-wide accepted lore to be understandable to any colleague.

Imagine the “generic 3-pseudosphere.” Its lower-dimensional analog in ordinary 3-space, the 2-pseudosphere (the so-called Newton pseudosphere) looks like two trumpets with infinitely long, infinitely thinned-out mouth pieces, glued together head-on with their bells ( http://en.wikipedia.org/wiki/File:The_Pseudosphere.jpg ). This smooth monster has the same volume as a sphere of the same (maximal) diameter, and also the same surface area and the same (if negative) curvature: a kind of miracle. Hence the name “pseudo-sphere.”

A Resilient Logic for Hazardous Times

Posted by in categories: complex systems, economics, engineering, ethics, existential risks, nuclear weapons, policy, sustainability
“If the rate of change on the outside
exceeds the rate of change on the inside, the end is near”
- Jack Welch

Complex societies are heavily addicted to expensive, vulnerable and potentially hazardous infrastructure. We rely on a healthy environment for production of food and access to clean water. We depend on technological infrastructure for energy supplies and communications. We are deeply addicted to economic growth to support growing populations and consumption. If one of these pillars of modern society crumbles our existence will collapse like a house of cards.

The interdependencies and complexities of the system we call modern society has become so intertangled that finding a robust and simple solution to our problems has become close to impossible. Historically the cold war gave us the logic of a “balance of terror”. This logic, originally concerned with a balance of U.S. vs. Soviet military capacities, has lead to an increasingly expensive way of reducing risk and ever expanding bureaucracies to keep us “virtually safe”.

With the onset of a global economic recession, drastic climate change, deadly natural disasters, raging civil wars and diminishing natural resources we need a new logic. A set of moral laws for reducing risk and mitigating consequences applicable at a low cost from the bottom up of entire societies.

The concept of resilience is based on the idea that disasters are inevitable and a natural part of existence. Our best defense is preparedness and engineering systems that not only can withstand heavy strains but also absorb damage. The Institute for Resilient Infrastructure at the University of Leeds gives this definition of “Resilience”;

Three Manifest Miracles in Physics: Qualia, the Now and the Higgs Field

Posted by in categories: existential risks, particle physics

The whole within which we find ourselves at every conscious moment is a miraculous gift that we take for granted in our culture. Everything can be understood inside the world, so we believe in science – except for the qualia (like color) and also for the Now which both are non-existent in physics (although this is almost never mentioned).

For 4 days now, something that unlike the qualia and the Now exists within rather than outside the scope of science is just as baffling: the Higgs field. As Matt Strassler explained two years ago, the everywhere constant Higgs field is responsible for the masses of all elementary particles – without an exchange of particles being involved — provided it will be discovered experimentally via the signature of a first field-specific particle. Thus an immutable constant influence makes itself felt inside creation for 4 days. The freshly discovered Higgs particle can be called the first unmistakable miracle found in nature, because it reflects the presence of an everywhere constant field of unknown origin.

The discovery comes with a price tag which is none of its own fault. The machine made to find it was designed so as to also generate a second totally new animal in the hope that at least one of the two would be found: miniature black holes. The latter have eluded finding so far we are told, but this is not certain: a double success cannot be excluded.

This is because a trivial new implication of Einstein’s “happiest thought” of 1907 revealed that black holes possess radically new properties. The latter cause black holes to arise much more readily and make them invisible to CERN’s detectors. In addition they grow exponentially inside matter. Therefore if one specimen gets stuck inside earth, the planet will be eaten inside out after an asymptomatic period of a few years, so as to assume the size of a chestnut while retaining its gravitational influence on the moon.

Per Aspera Ad Astra

Posted by in categories: economics, education, engineering, ethics, futurism, human trajectories, philosophy, policy, rants, scientific freedom, space, sustainability, transparency

The unknown troubles and attracts us. We long to discover a reason for our existence. We look out to the stars through the darkness of space to observe phenomena incredibly far distances away. Many of us are curious about the things we see, these unknowns.

Yet, many of us look skyward and are uninspired, believing that our time and resources best be kept grounded. Despite our human-centered ideologies, our self-assured prophecies, our religious and philosophical beliefs, no existential rationale seems apparent.

We as people welcome technology into our lives and use it constantly to communicate and function. Scientific discoveries pique the interest of every citizen in every country, and technological revolutions have always preceded social and political revolutions from the creation of the internet back to man’s first use of simple tools. Leaders of nations proclaim the importance of science and discovery to our welfare to be utmost.

But what we have seen done recently contradicts these proclamations: space programs are closed; science funding for schools always falls short; and we see no emphasis of the significance of science in our modern culture. Our governments call for the best but provide capital for only the satisfactory, if even. We no longer succumb to the allure of learning simply for the sake of knowing what we once did not know. We have stopped dreaming.
