Why it is dangerous to build ever larger big bang machines

CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?

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?”

Party Like It’s 1912…

Posted by in categories: asteroid/comet impacts, complex systems, economics, ethics, existential risks, fun, lifeboat, media & arts, rants

It’s the centennial year of the Titanic disaster, and that tragedy remains a touchstone.

The lifeboat angle is obvious. So is the ice hazard: then it was icebergs, now it’s comets.

But 100 years of expanding awareness has revealed the other threats we’re now aware of. We have to think about asteroids, nano- and genotech accidents, ill-considered high-energy experiments, economic and social collapse into oligarchy and debt peonage, and all the many others.

What a great subject for a Movie Night! Here are some great old movies about lifeboats and their discontents.

Earth’s Titanic Challenges

RMS <em>Titanic</em> Sails

What’s to worry? RMS Titanic departs Southampton.

This year marks the 100th anniversary of the Titanic disaster in 1912. What better time to think about lifeboats?

One way to start a discussion is with some vintage entertainment. On the centenary weekend of the wreck of the mega-liner, our local movie palace near the Hudson River waterfront ran a triple bill of classic films about maritime disasters: A Night to Remember, Lifeboat, and The Poseidon Adventure. Each one highlights an aspect of the lifeboat problem. They’re useful analogies for thinking about the existential risks of booking a passage on spaceship Earth.

LHC-Critique Press Info: Instead of a neutral risk assessment of the LHC: New records and plans for costly upgrades at CERN

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

High energy experiments like the LHC at the nuclear research centre CERN are extreme energy consumers (needing the power of a nuclear plant). Their construction is extremely costly (presently 7 Billion Euros) and practical benefits are not in sight. The experiments eventually pose existential risks and these risks have not been properly investigated.

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.

Critical Request to CERN Council and Member States on LHC Risks

Posted by in categories: complex systems, cosmology, engineering, ethics, existential risks, particle physics, policy

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.
