To Set the Record Straight

Posted by in categories: existential risks, particle physics

There is not the slightest alleviation of danger so far. All I can record so far is a stalling in favor of letting CERN continue till the end of the year – its present goal. No immediate safety discussion with CERN is planned by any organization if I am told correctly.

I would very much like to understand the mechanism: How is it possible that so many grown-up persons collude in a game of hide-and-seek: What do they gain by refusing to think and, most of all, discuss?

Their neglect of rationality is unprecedented. Imagine: A whole profession being too weak to find a single counterargument against the reproach of trying to vaporize the planet into a black hole in a few years’ time – with not a single member speaking up in objection!

A muse on why Telemach could actually be a Safety Assurance

Posted by in categories: existential risks, particle physics

The avid reader of Lifeboat may have noticed that the debate on LHC safety assurances has recently swerved here towards discussion on astronomical phenomenology — mainly the continued existence of white dwarfs and neutron stars.

The detailed G&M safety report naturally considers both of these, and considers hypothetical stable MBH capture rates based on a weak CR background flux. It actually overlooks better examples of white dwarfs which are part of a binary pair such as Sirius B, the little companion to one of our closest and brightest stars, Sirius A.

One could argue that white dwarfs are not greatly understood — but the relevant factors to the safety debate are quite understood — density, mass, escape velocity, and approximate age of such observed phenomenon. Only magnetic field effects are up for debate.

If Sirius B captured even one such MBH due to CR bombardment from its companion star in the first say 20 million years of its existence — and it would be difficult to argue that it would not — then that MBH would be accreting for the last 100 million years, through far denser material, and most likely at a much higher velocity, than any MBH captured in the Earth due to LHC collisions. Therefore, given the continued existence of Sirius B, accretion rates would therefore have to be incredibly slow and there would be no significant threat to Earth from what would be a much slower MBH accretion rate here.

I would be Grateful to Be Allowed to Speak at the CERN-Lifeboat Conference

Posted by in categories: existential risks, particle physics

But I would suggest CERN to select the majority of speakers and to make sure they are high-ranking and not necessarily on their payroll.

And Dr. W. Wagner and Mag. M. Goritschnig should be included, as well as the editor of Leonardo.

I also apologize for my having provoked G&M: they have all the chance of the world to defend their position. And no one would be happier than me if they prevailed. For as I always said I am CERN’s best friend. My having asked for a rebuttal was the opposite of an aggressive act: “science is friendship” by its definition. Lifeboat loves science.

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.

Nil Nocere, Dear CERN !

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]

CERN insists on believing in physical nonsense as a guarantee that their LHC experiment were innocuous. They refuse an update on their false “Safety Report” for almost 4 years.

The sacrosanct safety report dogmatically posits that one particular version of string theory possessed physical reality which no string theorist claims.

They refuse up-dating, open discussion and the necessary scientific safety conference for 4 years ( http://www.wissensnavigator.com/documents/PetitiontoCERN.pdf ). They thereby behave like medieval dogmatists.

CERN is so Important also because there Is no “E.T.” in the Galaxy

Posted by in categories: existential risks, particle physics

This note considers the possibility of earth being replaceable in the galaxy in the foreseeable future. The suggested answer is: no.

Let me explain why. For once, fundamental physics is not enough to understand the story since implied physical disciplines, chemistry and biology, come into play. The modern synthesis (Ernst Mayr) is presupposed. Stu Kauffmann and Joel Cohen stand in the background.

But are humans (the extinction of which the CERN debate is all about) not at the tip of the animal kingdom and hence similar tips should exist elsewhere? Our blue planet would then be not THAT important from a more sub specie aeternitatis viewpoint.

Even this consolation – if it qualifies for one – cannot be offered: Everything speaks in favor of the conclusion that humans are unique over vast stretches of the galaxy’s life-bearing quarters.

Dear World Press –You Could Help

Posted by in categories: existential risks, particle physics

Either I am a liar or not. You treat me like being one by your observing a world-wide curfew. I must have made grave mistakes in the past that explain this attitude.

I admit that my latest post on Oppenheimer is a bit technical since I mentioned the duration of a trip down to the horizon of the black hole remnant of a collapsed star and back. But my conclusion was easy to understand: If Oppie was right then both trips take an infinite outside time. Every high-school student can confirm this.

Therefore my public request to CERN, to please before starting 8 TeV proton collisions on a large scale tomorrow give a reason as to why they stick to a theory of black holes that denies Oppenheimer’s finding, is perhaps sufficiently grounded on facts to be worth reporting.

Forgive me for my turning to you directly.

Drawing a line on offensive/obscene posts against CERN

Posted by in categories: education, ethics, existential risks, lifeboat, particle physics

In light of continued frustration by many users, and due to a recent request by Prof Peter Howell on the lack of web administration on obscene/offensive posts and the effect this can have on the overall impression of Lifeboat, I have taken measures on cleaning up posts by a contributor who regularly depreciates the standards of what can otherwise be a fine blog of academic opinion. Apologies to Prof Otto Rossler — but referring to CERN as ‘urinating soldiers’ etc is far below the standards Lifeboat aspires to — Please clean up your act.

A Letter of Support for Antonio Ereditato

Posted by in categories: existential risks, particle physics

Professor Ereditato’s basic insight – that particles sent across differing longitudes can be technically speaking superluminal – was correct. This I showed in my paper on Lifeboat submitted to Science ( https://russian.lifeboat.com/blog/2011/10/%E2%80%9Ctwo-perce…ting-earth ).

I regret the unscientific demand for clairvoyance-in-retrospect – not to have seen that the effect is technically smaller than claimed – which led to his resignation from “Opera” about which fact I learned today from a newspaper.

His enthusiasm and openness to the new is sorely needed by the scientific community. I would like to ask CERN to re-hire him. You cannot let your best man go.

Oppie’s Black Holes versus CERN

Posted by in categories: existential risks, particle physics

Six years before Oppenheimer declared physics to be sinful after his success at building the bomb, he had discovered the existence of black holes as solutions to the Einstein equation. It took the physics community 30 years to fully believe him.

He found two things. (1) An astronaut jumping in takes infinitely long to disappear from sight (provided one could see him that long since the frequency of the light emitted by him goes to zero). (2) On his own wristwatch, only 2 days passed until he reached the surface of the star-mass black hole. Both results are still accepted.

Oppenheimer knew that if a trampoline were installed on the surface, enabling the astronaut to jump back up uninjured, both results are valid again: Up to his return to from where he came, 2 days would pass on his own wristwatch again. But for the outside world, once more an infinite amount of time would have passed.

This simple result is universally accepted but for some reason virtually unknown. It goes under the name “gravitational twins paradox.” No specialist denies it but virtually each will admit that it is new to him or her.
