CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.
Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”
“There is always going to be more deep physics to be conducted with larger and larger colliders. My question is to what extent will the knowledge that we already have be extended to benefit humanity?”
There have been broad discussions about whether high energy nuclear experiments could pose an existential risk sooner or later, for example by producing micro black holes (mBH) or strange matter (strangelets) that could convert ordinary matter into strange matter and that eventually could start an infinite chain reaction from the moment it was stable – theoretically at a mass of around 1000 protons.
CERN has argued that micro black holes eventually could be produced, but they would not be stable and evaporate immediately due to „Hawking radiation“, a theoretical process that has never been observed.
Furthermore, CERN argues that similar high energy particle collisions occur naturally in the universe and in the Earth’s atmosphere, so they could not be dangerous. However, such natural high energy collisions are seldom and they have only been measured rather indirectly. Basically, nature does not set up LHC experiments: For example, the density of such artificial particle collisions never occurs in Earth’s atmosphere. Even if the cosmic ray argument was legitimate: CERN produces as many high energy collisions in an artificial narrow space as occur naturally in more than hundred thousand years in the atmosphere. Physicists look quite puzzled when they recalculate it.
Others argue that a particle collider ring would have to be bigger than the Earth to be dangerous.
A study on “Methodological Challenges for Risks with Low Probabilities and High Stakes” was provided by Lifeboat member Prof Raffaela Hillerbrand et al. Prof Eric Johnson submitted a paper discussing juridical difficulties (lawsuits were not successful or were not accepted respectively) but also the problem of groupthink within scientific communities. More of important contributions to the existential risk debate came from risk assessment experts Wolfgang Kromp and Mark Leggett, from R. Plaga, Eric Penrose, Walter Wagner, Otto Roessler, James Blodgett, Tom Kerwick and many more.
Since these discussions can become very sophisticated, there is also a more general approach (see video): According to present research, there are around 10 billion Earth-like planets alone in our galaxy, the Milky Way. Intelligent life might send radio waves, because they are extremely long lasting, though we have not received any (“Fermi paradox”). Theory postulates that there could be a ”great filter“, something that wipes out intelligent civilizations at a rather early state of their technical development. Let that sink in.
All technical civilizations would start to build particle smashers to find out how the universe works, to get as close as possible to the big bang and to hunt for the smallest particle at bigger and bigger machines. But maybe there is a very unexpected effect lurking at a certain threshold that nobody would ever think of and that theory does not provide. Indeed, this could be a logical candidate for the “great filter”, an explanation for the Fermi paradox. If it was, a disastrous big bang machine eventually is not that big at all. Because if civilizations were to construct a collider of epic dimensions, a lack of resources would have stopped them in most cases.
Finally, the CERN member states will have to decide on the budget and the future course.
The political question behind is: How far are the ordinary citizens paying for that willing to go?

]]>Why the LHC must be shut down
]]>It is not the first time that CERN announces record energies and news around April 1 – apparently hoping that some critique and concerns about the risks could be misinterpreted as an April joke. Additionally CERN regularly starts up the LHC at Easter celebrations and just before week ends, when news offices are empty and people prefer to have peaceful days with their friends and families.
CERN has just announced new records in collision energies at the LHC. And instead of conducting a neutral risk assessment, the nuclear research centre plans costly upgrades of its Big Bang machine. Facing an LHC upgrade in 2013 for up to CHF 1 Billion and the perspective of a Mega-LHC in 2022: How long will it take until risk researchers are finally integrated in a neutral safety assessment?
There are countless evidences for the necessity of an external and multidisciplinary safety assessment of the LHC. According to a pre-study in risk research, CERN fits less than a fifth of the criteria for a modern risk assessment (see the press release below). It is not acceptable that the clueless member states point at the operator CERN itself, while this regards its self-set security measures as sufficient, in spite of critique from risk researchers, continuous debates and the publication of further papers pointing at concrete dangers and even existential risks (black holes, strangelets) eventually arising from the experiments sooner or later. Presently science has to admit that the risk is disputed and basically unknown.
It will not be possible to keep up this ostrich policy much longer. Especially facing the planned upgrades of the LHC, CERN will be confronted with increasing critique from scientific and civil side that the most powerful particle collider has yet not been challenged in a neutral and multidisciplinary safety assessment. CERN has yet not answered to pragmatic proposals for such a process that also should constructively involve critics and CERN. Also further legal steps from different sides are possible.
The member states that are financing the CERN budget, the UN or private funds are addressed to provide resources to finally initiate a neutral and multidisciplinary risk assessment.

]]>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 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.
