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(!).
One might really ask where this should lead to – sooner or later – without the risks being properly investigated.
For comparison: The AMS experiment for directly measuring cosmic rays in the atmosphere operates on a scale around 1.5 TeV. Very high energetic cosmic rays have only been measured indirectly (their impulse). Sort, velocity, mass and origin of these particles are unknown. In any way, the number of collisions under the extreme and unprecedented artificial conditions at the LHC is of astronomical magnitudes higher than anywhere else in the nearer cosmos.
There were many talks on machine safety at the Chamonix meeting. The safety of humans and environment obviously were not an official topic. No reaction on the recent claim for a really neutral, external and multi-disciplinary risk assessment by now.
Official reports from the LHC performance workshop by CERN Bulletin:
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.
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.
Given Ars Electronica’s spotlight on CERN and its experimental sub-nuclear research reactor, Maturana’s explanations were especially important, which to the assembled CERN celebrities may have come in a mixture of an unpleasant surprise and a lack of relation to them.
During the question-and-answer period, Markus Goritschnig asked Maturana whether it wasn’t problematic that CERN is basically controlling itself and discarding a number of existential risks discussed related to the LHC — including hypothetical but mathematically demonstrable risks also raised — and later downplayed — by physicists like Nobel Prize winner Frank Wilczek, and whether he thought it necessary to integrate in the LHC safety assessment process other sciences aside from physics such as risk search. In response Maturana replied (in the video from about 1:17): “We human beings can always reflect on what we are doing and choose. And choose to do it or not to do it. And so the question is, how are we scientists reflecting upon what we do? Are we taking seriously our responsibility of what we do? […] We are always in the danger of thinking that, ‘Oh, I have the truth’, I mean — in a culture of truth, in a culture of certainty — because truth and certainty are not as we think — I mean certainty is an emotion. ‘I am certain that something is the case’ means: ‘I do not know’. […] We cannot pretend to impose anything on others; we have to create domains of interrogativity.”
Disregarding these reflections, Sergio Bertolucci (CERN) found the peer review system among the physicists’ community a sufficient scholarly control. He refuted all the disputed risks with the “cosmic ray argument,” arguing that much more energetic collisions are naturally taking place in the atmosphere without any adverse effect. This safety argument by CERN on the LHC, however, can also be criticized under different perspectives, for example: Very high energetic collisions could be measured only indirectly — and the collision frequency under the unprecedented artificial and extreme conditions at the LHC is of astronomical magnitudes higher than in the Earth’s atmosphere and anywhere else in the nearer cosmos.
The second presentation of the “Origin” Symposium III was held by Roger Malina, an astrophysicist and the editor of “Leonardo” (MIT Press), a leading academic journal for the arts, sciences and technology.
Malina opened with a disturbing fact: “95% of the universe is of an unknown nature, dark matter and dark energy. We sort of know how it behaves. But we don’t have a clue of what it is. It does not emit light, it does not reflect light. As an astronomer this is a little bit humbling. We have been looking at the sky for millions of years trying to explain what is going on. And after all of that and all those instruments, we understand only 3% of it. A really humbling thought. […] We are the decoration in the universe. […] And so the conclusion that I’d like to draw is that: We are really badly designed to understand the universe.”
The main problem in research is: “curiosity is not neutral.” When astrophysics reaches its limits, cooperation between arts and science may indeed be fruitful for various reasons and could perhaps lead to better science in the end. In a later communication Roger Malina confirmed that the same can be demonstrated for the relation between natural sciences and humanities or social sciences.
However, the astronomer emphasized that an “art-science collaboration can lead to better science in some cases. It also leads to different science, because by embedding science in the larger society, I think the answer was wrong this morning about scientists peer-reviewing themselves. I think society needs to peer-review itself and to do that you need to embed science differently in society at large, and that means cultural embedding and appropriation. Helga Nowotny at the European Research Council calls this ‘socially robust science’. The fact that CERN did not lead to a black hole that ended the world was not due to peer-review by scientists. It was not due to that process.”
One of Malina’s main arguments focused on differences in “the ethics of curiosity”. The best ethics in (natural) science include notions like: intellectual honesty, integrity, organized scepticism, dis-interestedness, impersonality, universality. “Those are the believe systems of most scientists. And there is a fundamental flaw to that. And Humberto this morning really expanded on some of that. The problem is: Curiosity is embodied. You cannot make it into a neutral ideal of scientific curiosity. And here I got a quote of Humberto’s colleague Varela: “All knowledge is conditioned by the structure of the knower.”
In conclusion, a better co-operation of various sciences and skills is urgently necessary, because: “Artists asks questions that scientists would not normally ask. Finally, why we want more art-science interaction is because we don’t have a choice. There are certain problems in our society today that are so tough we need to change our culture to resolve them. Climate change: we’ve got to couple the science and technology to the way we live. That’s a cultural problem, and we need artists working on that with the scientists every day of the next decade, the next century, if we survive it.
Then Roger Malina directly turned to the LHC safety discussion and articulated an open contradiction to the safety assurance pointed out before: He would generally hope for a much more open process concerning the LHC safety debate, rather than discussing this only in a narrow field of particle physics, concrete: “There are certain problems where we cannot cloister the scientific activity in the scientific world, and I think we really need to break the model. I wish CERN, when they had been discussing the risks, had done that in an open societal context, and not just within the CERN context.”
Presently CERN is holding its annual meeting in Chamonix to fix LHC’s 2012 schedules in order to increase luminosity by a factor of four for maybe finally finding the Higgs Boson – against a 100-Dollar bet of Stephen Hawking who is convinced of Micro Black Holes being observed instead, immediately decaying by hypothetical “Hawking Radiation” — with God Particle’s blessing. Then it would be himself gaining the Nobel Prize Hawking pointed out. Quite ironically, at Ars Electronica official T-Shirts were sold with the “typical signature” of a micro black hole decaying at the LHC – by a totally hypothetical process involving a bunch of unproven assumptions.
In 2013 CERN plans to adapt the LHC due to construction failures for up to CHF 1 Billion to run the “Big Bang Machine” at double the present energies. A neutral and multi-disciplinary risk assessment is still lacking, while a couple of scientists insist that their theories pointing at even global risks have not been invalidated. CERN’s last safety assurance comparing natural cosmic rays hitting the Earth with the LHC experiment is only valid under rather narrow viewpoints. The relatively young analyses of high energetic cosmic rays are based on indirect measurements and calculations. Sort, velocity, mass and origin of these particles are unknown. But, taking the relations for granted and calculating with the “assuring” figures given by CERN PR, within ten years of operation, the LHC under extreme and unprecedented artificial circumstances would produce as many high energetic particle collisions as occur in about 100.000 years in the entire atmosphere of the Earth. Just to illustrate the energetic potential of the gigantic facility: One LHC-beam, thinner than a hair, consisting of billions of protons, has got the power of an aircraft carrier moving at 12 knots.
This article in the Physics arXiv Blog (MIT’s Technology Review) reads: “Black Holes, Safety, and the LHC Upgrade — If the LHC is to be upgraded, safety should be a central part of the plans.”, closing with the claim: “What’s needed, of course, is for the safety of the LHC to be investigated by an independent team of scientists with a strong background in risk analysis but with no professional or financial links to CERN.” http://www.technologyreview.com/blog/arxiv/27319/
Australian ethicist and risk researcher Mark Leggett concluded in a paper that CERN’s LSAG safety report on the LHC meets less than a fifth of the criteria of a modern risk assessment. There but for the grace of a goddamn particle? Probably not. Before pushing the LHC to its limits, CERN must be challenged by a really neutral, external and multi-disciplinary risk assessment.
Video recordings of the “Origin III” symposium at Ars Electronica: Presentation Humberto Maturana:
Experts regard safety report on Big Bang Machine as insufficient and one-dimensional
International critics of the high energy experiments planned to start soon at the particle accelerator LHC at CERN in Geneva have submitted a request to the Ministers of Science of the CERN member states and to the delegates to the CERN Council, the supreme controlling body of CERN.
The paper states that several risk scenarios (that have to be described as global or existential risks) cannot currently be excluded. Under present conditions, the critics have to speak out against an operation of the LHC.
The submission includes assessments from expertises in the fields markedly missing from the physicist-only LSAG safety report — those of risk assessment, law, ethics and statistics. Further weight is added because these experts are all university-level experts – from Griffith University, the University of North Dakota and Oxford University respectively. In particular, it is criticised that CERN’s official safety report lacks independence – all its authors have a prior interest in the LHC running and that the report uses physicist-only authors, when modern risk-assessment guidelines recommend risk experts and ethicists as well.
As a precondition of safety, the request calls for a neutral and multi-disciplinary risk assessment and additional astrophysical experiments – Earth based and in the atmosphere – for a better empirical verification of the alleged comparability of particle collisions under the extreme artificial conditions of the LHC experiment and relatively rare natural high energy particle collisions: “Far from copying nature, the LHC focuses on rare and extreme events in a physical set up which has never occurred before in the history of the planet. Nature does not set up LHC experiments.”
Even under greatly improved circumstances concerning safety as proposed above, big jumps in energy increase, as presently planned by a factor of three compared to present records, without carefully analyzing previous results before each increase of energy, should principally be avoided.
The concise “Request to CERN Council and Member States on LHC Risks” (Pdf with hyperlinks to the described studies) by several critical groups, supported by well known critics of the planned experiments:
The answer received by now does not consider these arguments and studies but only repeats again that from the side of the operators everything appears sufficient, agreed by a Nobel Price winner in physics. LHC restart and record collisions by factor 3 are presently scheduled for March 30, 2010.
