This essay was posted previously last year and removed and has appeared in abridged form in the European Space Safety online Magazine and can also be found on Yahoo voices.

Several dates are cited as marking the beginning of the space age. Sputnik, October 4th, 1957, Yuri’s day April 12th, 1961, and the first successful V-2 launch by the Nazis on October 3rd, 1942, to name a few. Some prefer December 21st, 1968, when human beings first escaped the Earth’s gravitational field on Apollo 8. When studying the events that allowed man to leave Earth, future historians may agree on a date not generally associated with space flight. July 16th, 1945 was Trinity, the first nuclear weapon test. Stanislaw Ulam, a 36-year-old Polish mathematician who helped build “the gadget”, visited ground zero after the test. Ulam later conceived the idea of propelling a spaceship with atomic bombs. Near the end of his life the eccentric genius stated the idea was his greatest work.

When considering nuclear propulsion, it must be understood that space is not an ocean, though often characterized as one. The distances and conditions are not comparable. While chemical energy has allowed humankind to travel across and above the surface of Earth, the energy required to travel in space is of a different order. Water, in the form of steam, was the agent of change that brought about the industrial revolution. Fossil fuel, burned and transformed by steam into mechanical work, would radically change the world in the span of a century. What is difficult for moderns to understand is not only how limited human capabilities were before steam, but how limited they are in the present in terms of space travel. The psychological limits of human beings limit space journeys to a few years. Chemical propulsion is not capable of taking human beings to the outer solar system and back within those crew limits. The solution is a reaction one million times more powerful. Nuclear energy is to the space age as steam was to the industrial age.

A Resilient Logic for Hazardous Times

Posted by in categories: complex systems, economics, engineering, ethics, existential risks, nuclear weapons, policy, sustainability
“If the rate of change on the outside
exceeds the rate of change on the inside, the end is near”
- Jack Welch

Complex societies are heavily addicted to expensive, vulnerable and potentially hazardous infrastructure. We rely on a healthy environment for production of food and access to clean water. We depend on technological infrastructure for energy supplies and communications. We are deeply addicted to economic growth to support growing populations and consumption. If one of these pillars of modern society crumbles our existence will collapse like a house of cards.

The interdependencies and complexities of the system we call modern society has become so intertangled that finding a robust and simple solution to our problems has become close to impossible. Historically the cold war gave us the logic of a “balance of terror”. This logic, originally concerned with a balance of U.S. vs. Soviet military capacities, has lead to an increasingly expensive way of reducing risk and ever expanding bureaucracies to keep us “virtually safe”.

With the onset of a global economic recession, drastic climate change, deadly natural disasters, raging civil wars and diminishing natural resources we need a new logic. A set of moral laws for reducing risk and mitigating consequences applicable at a low cost from the bottom up of entire societies.

The concept of resilience is based on the idea that disasters are inevitable and a natural part of existence. Our best defense is preparedness and engineering systems that not only can withstand heavy strains but also absorb damage. The Institute for Resilient Infrastructure at the University of Leeds gives this definition of “Resilience”;

Per Aspera Ad Astra

Posted by in categories: economics, education, engineering, ethics, futurism, human trajectories, philosophy, policy, rants, scientific freedom, space, sustainability, transparency

The unknown troubles and attracts us. We long to discover a reason for our existence. We look out to the stars through the darkness of space to observe phenomena incredibly far distances away. Many of us are curious about the things we see, these unknowns.

Yet, many of us look skyward and are uninspired, believing that our time and resources best be kept grounded. Despite our human-centered ideologies, our self-assured prophecies, our religious and philosophical beliefs, no existential rationale seems apparent.

We as people welcome technology into our lives and use it constantly to communicate and function. Scientific discoveries pique the interest of every citizen in every country, and technological revolutions have always preceded social and political revolutions from the creation of the internet back to man’s first use of simple tools. Leaders of nations proclaim the importance of science and discovery to our welfare to be utmost.

But what we have seen done recently contradicts these proclamations: space programs are closed; science funding for schools always falls short; and we see no emphasis of the significance of science in our modern culture. Our governments call for the best but provide capital for only the satisfactory, if even. We no longer succumb to the allure of learning simply for the sake of knowing what we once did not know. We have stopped dreaming.

Médecins Sans Frontières Scientific Day 2012

Posted by in categories: complex systems, geopolitics, policy, sustainability

Every year Médecins Sans Frontières/ Doctors Without Borders (MSF) hold a conference to present scientific research carried out by their teams from different parts of the world. This year’s conference highlighted some of the strategic challenges facing MSF, and challenged some of our conceptions of medical humanitarian aid, and international development in light of groundbreaking digital technologies. We are as Paul Conneally passionately articulated in his keynote speech – Digital Humanitarian – ‘on the cusp of a global health revolution’.

Some of the groundbreaking technologies touched upon included crisis mapping, a technology that is still in its infancy, and the era of big data. The possibilities of how healthcare and humanitarian aid will be transformed by the convergence of ideas and technologies were evident in the poster session; humanitarian technology applications showed refugee camps in Kenya being monitored using satellite imagery and a humanitarian field software kit called joekit. Of the talks demonstrating real world examples, a talk by Isabella Panunzi on teleradiology proved to be immensely inspiring.

Isabella’s talk on her experience of applying teleradiology to improve diagnosis of tuberculosis in Thyolo District Hospital, Malawi showcased humanitarian innovation at its best. X-rays are taken at the Malawi hospital and the images are then sent to radiologists in the USA to interpret the images. As a result teleradiology has reduced critical delays and missed diagnosis of TB. This example of digital humanitarianism symbolises a small fraction of what can be potentially achieved in transforming our world. It opens up new possibilities in the transfer of technology and knowledge to the developing world. It also highlights the need for a different approach to modelling the strategic challenges of medical humanitarian aid and international development, and this is where complexity thinking and science can bring together different parts of problems and solutions to construct true holistic solutions.

A talk by Jonathan Smith, lecturer in Global Health and Epidemiology of Microbial Diseases at Yale University, brought together the disciplines of the arts and sciences as he gave an inventive take on using research in the digital age. Visually documenting disease and connecting the ‘emotional component to epidemiological data’ is extremely powerful to create change in global health observed Jonathon, as he showed part of a documentary film he is directing, ‘They Go to Die’, a film about,

Spiralling Debt & The Road to Breaking Point

Posted by in categories: business, economics, ethics, finance, sustainability

The biggest challenge to the ‘ecosystem’ of world economics that keeps society ticking over is how to overcome our inability to regulate a sustainable economic model. In Europe at present we are undergoing the difficult measures in setting about rules of austerity to ensure that government borrowing never gets as out of hand as it has done on our watch. I post on this topic now as it is topical to me — back home here in my native Ireland we are voting on a referendum this week to ensure we no longer borrow from our children to fuel indulgences today — a referendum on rationality and responsibility.

The topical of austerity reminds me of an opinion I blogged on a crisis in the Obama administration last August on national debt in the light of striking comments from foreign figureheads amid the storm from the ‘Tea Party Taliban’. I share with you for to see if anyone cares to comment on an operandi of living like parasites off the global economy:

Living Like Parasites Off The Global Economy, originally written 3 Aug 2011:

With the US in turmoil over its national debt, and held to ransom by a ‘Tea Party Taliban’, last week China publicly mocked American democracy. Yesterday, the world witnessed the humbling of America after a trillion-dollar deal marked the end of an era for the US. The US now faces a shift in its relations with creditor nations, and it was not all too surprising to hear Vladimir Putin, the Russian Prime Minister, yesterday accusing Americans of living “like parasites off the global economy”. If America had defaulted on its international debt obligations, that is exactly what it would be. While America continues to service it’s debt, it is quite the opposite — for now at least- as is perpetually paying interest to its creditors.

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.

Sub-Keplerian MBH: Planetary Heating or Eventual Accretion

Posted by in categories: ethics, existential risks, particle physics, sustainability

Hi All, I have now uploaded Rev 1.7 of my new short paper “Micro black holes — Exploring Terra Flux of Hypothetical Stable MBH Produced in Colliders Relative to Natural Cosmic Ray Exposure”: http://environmental-safety.webs.com/mbh_terra_flux.pdf

Prompted by Prof O.E. Rossler’s recent publication of his Telemach theorem — but not dependant on it, this paper looks at the relative flux (km per km) of micro black holes through the Earth — if created by the LHC — when compared to the flux caused by cosmic ray collisions in nature. It endorses Otto’s viewpoint that if Telemach were correct, then safety assurance is solely based on the disputed neutron star & white dwarf safety arguments.

The focus of the paper however is that of relative flux — and a derived micro black hole flux ratio of almost a one million fold increase relative to that generated by natural cosmic ray collisions with the Earth. Furthermore, the alternative prospect to accretion in the case of such an elevated flux is planetary heating through Hawking Radiation — as explored by other research — a scenario in which the neutron star safety argument is irrelevant - as their survival does not prove/disprove anything in this outcome. Feedback as always welcome.

This derivation of flux is distinct from previous CERN statements which made direct comparisons to rates of collisions (a 10,000 fold increase during operations) - as I consider the flux of products as a function of kilometres of matter traversed — a more relevant metric.

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.
