Either Ten Thousand Physicists Err or One – A Last-Minute Pledge to the Media

Posted by in categories: existential risks, particle physics

It would be a “first” in history – that a whole profession refuses to think. That they would be so much scared by the fact that a trivial new result when taken seriously can prevent Armageddon that they would rather not believe than check it.

This sounds very unlikely indeed. The trivial result in question is the “ontological Einstein.” His relativity theory possesses additional ontological implications besides the famous twin-clocks paradox of 1905. Let me briefly state my point.

Every high-school student learns that a travelled twin is younger upon return than the brother who stayed at home. In other words he is ontologically younger. Einstein’s first example was two mechanical clocks on which the difference is objectively verifiable (one being late). “Ontological” is derived from the Greek word “on” (with a long “o”) which means “being in reality.” This is the single most intimidating result of Einstein. It has nothing to do with observation from a distance as relativity is often understood, but represents a tangible reality. No professional physicist puts it in doubt (except ideologists like the “100 Authors Against Einstein” of 1930). A second result of the same miraculous kind applies in gravity as specialists know (Frolov and Novikov’s book “Black Hole Physics” of 1998 provides helpful information on page 20, bottom). In this second twins paradox, it is the descended twin that after having been hauled back up again is ontologically younger than the one that stood put upstairs. Everybody is familiar to date with this “slower-aging effect” from the Global Positioning System (G.P.S.) whose earthbound clocks are manifestly slower than their twins in the satellites overhead.

But if this is well known – where lies the problem? It is only the implications that are ignored. It is three: the slowed-down clocks (and everything else downstairs) are,

LHC-Critique PRESS RELEASE (Feb 13 2012): CERN plans Mega-particle collider. COMMUNICATION to CERN: For a neutral and multi-disciplinary risk assessment before any LHC upgrade

Posted by in categories: cosmology, engineering, ethics, existential risks, futurism, nuclear energy, particle physics, philosophy, physics, scientific freedom, space, sustainability, transparency

- CERN’s annual meeting to fix LHC schedules in Chamonix: Increasing energies. No external and multi-disciplinary risk assessment so far. Future plans targeting at costly LHC upgrade in 2013 and Mega-LHC in 2022.

- COMMUNICATION to CERN – For a neutral and multi-disciplinary risk assessment before any LHC upgrade

According to CERN’s Chamonix workshop (Feb. 6–10 2012) and a press release from today: In 2012 the collision energies of the world’s biggest particle collider LHC should be increased from 3.5 to 4 TeV per beam and the luminosity is planned to be increased by a factor of 3. This means much more particle collisions at higher energies.

CERN plans to shut down the LHC in 2013 for about 20 months to do a very costly upgrade (for CHF 1 Billion?) to run the LHC at double the present energies (7 TeV per beam) afterwards.

CERN’s annual Chamonix-meeting to fix LHC schedules (Feb. 6–10 2012): Increasing energies. No external and multi-disciplinary risk assessment so far. Future plans targeting at Mega-LHC.

Posted by in categories: cosmology, engineering, ethics, events, existential risks, particle physics, physics, scientific freedom, sustainability, transparency

Info on the outcomes of CERN’s annual meeting in Chamonix this week (Feb. 6–10 2012):

In 2012 LHC collision energies should be increased from 3.5 to 4 TeV per beam and the luminosity is planned to be highly increased. This means much more particle collisions at higher energies.

CERN plans to shut down the LHC in 2013 for about 20 months to do a very costly upgrade (CHF 1 Billion?) to run the LHC at 7 TeV per beam afterwards.

Future plans: A High-Luminosity LHC (HL-LHC) is planned, “tentatively scheduled to start operating around 2022” — with a beam energy increased from 7 to 16.5 TeV(!).

Badly designed to understand the Universe — CERN’s LHC in critical Reflection by great Philosopher H. Maturana and Astrophysicist R. Malina

Posted by in categories: complex systems, cosmology, education, engineering, ethics, existential risks, futurism, media & arts, particle physics, philosophy, physics, scientific freedom, sustainability

Famous Chilean philosopher Humberto Maturana describes “certainty” in science as subjective emotional opinion and astonishes the physicists’ prominence. French astronomer and “Leonardo” publisher Roger Malina hopes that the LHC safety issue would be discussed in a broader social context and not only in the closer scientific framework of CERN.

(Article published in “oekonews”: http://oekonews.at/index.php?mdoc_id=1067777 )

The latest renowned “Ars Electronica Festival” in Linz (Austria) was dedicated in part to an uncritical worship of the gigantic particle accelerator LHC (Large Hadron Collider) at the European Nuclear Research Center CERN located at the Franco-Swiss border. CERN in turn promoted an art prize with the idea to “cooperate closely” with the arts. This time the objections were of a philosophical nature – and they had what it takes.

In a thought provoking presentation Maturana addressed the limits of our knowledge and the intersubjective foundations of what we call “objective” and “reality.” His talk was spiked with excellent remarks and witty asides that contributed much to the accessibility of these fundamental philosophical problems: “Be realistic, be objective!” Maturana pointed out, simply means that we want others to adopt our point of view. The great constructivist and founder of the concept of autopoiesis clearly distinguished his approach from a solipsistic position.

The Greenland Ice Sheet Melt: Irreversible Implications

Posted by in categories: economics, engineering, existential risks, habitats, sustainability

It is of course widely accepted that the Greenland icesheet is melting at an alarming rate, accelerating, and is an irreversible process, and when it finally does melt will contribute to a rise in sea levels globally by 7 meters. This is discounting the contribution of any melt from the West Antarctic ice sheet which could contribute a further 5 meters, and the more long term risk of East Antarctic ice sheet melt, which is losing mass at a rate of 57 billion tonnes per year, and if melted in entirety would see sea levels rise by a further 60 meters.

In this light it is rather ‘cute’ that the site here dedicated to existential risks to society is called the Lifeboat Foundation when one of our less discussed risks is that of world-wide flooding of a massive scale to major coastal cities/ports & industries right across the world.

Why do we still continue to grow our cities below a safe limit of say 10 meters above sea level when cities are built to last thousands of years, but could now be flooded within hundreds. How many times do we have to witness disaster scenarios such as the Oklahoma City floods before we contemplate this occurring irreversibly to hundreds of cities across the world in the future. Is it feasible to take the approach of building large dams to preserve these cities, or is it a case of eventually evacuating and starting all over again? In the latter case, how do we safely contain chemical & nuclear plants that would need to be abandoned in a responsible and non-environmentally damaging procedure?

Let’s be optimistic here — the Antarctic ice sheets are unlikely to disappear in time scales we need to worry about today — but the Greenland ice sheet is topical. Can it be considered an existential risk if the process takes hundreds of years and we can slowly step out of the way though so much of the infrastructure we rely on is being relinquished? Will we just gradually abandon our cities to higher ground as insurance companies refuse to cover properties in coastal flooding areas? Or will we rise to a challenge and take first steps to create eco-bubbles & ever larger dams to protect cities?

The Fairy Tale of the Sky-blue Planet and the Little Kid That Could Rescue All

Posted by in categories: existential risks, particle physics

Once upon a time there was a cute little planet in the vast recesses of the sky. It was rich in water and mountains and was blessed – with good parents. The kids were allowed to play all day, and their coaches were able to lay the connections into the impending adult life in a way that did not hurt.

So the planet could have gone on forever. But, as in every serious fairy tale, there was a single bad sorcerer who had caused many kids to fall into holes from which they had great difficulty escaping – a sly activity which seemed to amuse him. The doting parents had to learn how to warn their children, and from then on his influence faded.

This fact caused the bad sorcerer to change his evil tactics: by confusing the parents ahead of the kids. This is where our hero – Farwinner – enters the tale. He asked his father: what does the sorcerer’s public slogan “Caution is stupid” mean? The father said it means that cars need no brakes. But this is not true!, Farwinner complained. Not even if it makes the cars very much cheaper?, his father replied. Of course not, said Farwinner: would you drive with us in a car without brakes? His father had to promise him with a slap on the hand to give up on the idea.

The sorcerer learned about this event and got furious: “This little Telemach” (he referred to Farwinner in a foreign language) is becoming a nuisance. I need to immunize everyone else against his influence.

The runaway greenhouse reversal: Cooling Venus

Posted by in categories: chemistry, existential risks, futurism, habitats, space

As we all know, Venus’s atmosphere & temperature makes it too hostile for colonization: 450°C temperatures and an average surface pressure almost 100 times that of Earth. Both problems are due to the size of its atmosphere — massive — and 95% of which is CO2.

The general consensus is that Venus was more like that of the Earth several billion years ago, with liquid water on the surface, but a runaway greenhouse effect may have been caused by the evaporation of the surface water and subsequent rise of greenhouse gases.

It poses not just a harsh warning of the prospects of global warming on Earth, but also a case study for how to counter such effects — reversing the runaway greenhouse effect.

I have wondered if anyone has given serious thought to chemical processes which could be set in motion on Venus to extract the carbon dioxide from the atmosphere. The most common gas in the Universe is of course hydrogen, and if sufficient quantities could be introduced to the Venusian atmosphere, with the appropriate catalysts, could the carbon dioxide in the atmosphere be eventually reversed back into solid carbon compounds, water vapor and oxygen? The effect of this would of course not only bring down the temperature, but return the surface pressure, with 95% of its atmosphere removed, to one more similar to that of Earth. Perhaps in adding other aerosols the temperatures could be reduced further and avoid a re-runaway effect.

The Petty Non-offenses of the German Head of State, Taken together with His Brave Perseverance

Posted by in categories: existential risks, particle physics

[Disclaimer: This contribution does not reflect the views of the Lifeboat Foundation as with the scientific community in general, but individual sentiment — Web Admin]

These presently offer the world the unique chance that a high-ranking personality on the planet has the courage to ask to be officially informed about CERN’s legal status before the International Court of Crimes against Humanity before which it was accused more than 3 years ago without any defense ever having come forward.

The issue on hand concerns scientific ethics: CERN refuses to offer a counterargument for nearly 4 years. And, to the best of the present writer’s knowledge, no scientist speaks up in person on behalf of CERN by offering a scientific counterargument that he or she would be ready to defend. The much simplified 2010 theorem proving the danger was not even attempted to be defeated by a scientist.

Einstein’s famous gravitational frequency shift is accompanied by an equally strong change in particle mass and particle charge, both locally undetectable too. The new-found corollaries to Einstein’s famous “happiest thought” endow black holes with radically new properties. These properties not only render CERN’s detectors blind to its most hoped-for product (black holes) but do simultaneously enhance the probability of the successful production of black holes – an ominous combination. The first sufficiently slow specimen produced will take lodging inside earth – to grow there exponentially leaving nothing but a 2-cm black relic of our planet after a few years’ time.

The Difference Between a Lunar Base and Colony

Posted by in categories: existential risks, habitats, lifeboat, space, sustainability

Recently, Newt Gingrich made a speech indicating that, if elected, he would want 10% of NASA’s budget ($1.7 billion per year) set aside to fund large prizes incentivizing private industry to develop a permanent lunar base, a new propulsion method, and eventually establishing a martian base.

THE FINANCIAL FEASIBILITY OF A LUNAR BASE
Commentators generally made fun of his speech with the most common phrase used being “grandiose”. Perhaps. But in 1996 the Human Lunar Return study estimated $2.5 billion from NASA to send and return a human crew to the Moon. That was before SpaceX was able to demonstrate significant reductions in launch costs. One government study indicated 1/3 of the cost compared to traditional acquisition methods. Two of SpaceX’s Falcon Heavies will be able to launch nearly as much payload as the Saturn V while doing so at 1/15th the cost of the same mass delivered by the Shuttle.

So, we may be at the place where a manned lunar base is within reach even if we were to direct only 10% of NASA’s budget to achieve it.

I’m not talking about going to Mars with the need for shielding but rather to make fast dashes to the Moon and have our astronauts live under Moon dirt (regolith) shielding while exploiting lunar ice for air, water, and hence food.

Einstein Found ”Gravitational Clock-slowing“ – I Say the Latter Finding Implies “Gravitational Photon-mass Reduction”

Posted by in categories: existential risks, particle physics

Every high-school student can confirm this conclusion, but the Albert-Einstein-Institute says this conclusion is false. For it implies if true that CERN is building a planet-buster – a fact which must perhaps not become known at the time of a planned new war.
