Swine Flu Update: are we entering an Age of Pandemics?

Posted by in categories: biological, biotech/medical, existential risks, futurism, geopolitics, nanotechnology, space, sustainability

May 2: Many U.S. emergency rooms and hospitals crammed with people… ”Walking well” flood hospitals… Clinics double their traffic in major cities … ER rooms turn away EMT cases. — CNN

Update May 4: Confirmed cases of H1N1 virus now at 985 in 20 countries (Mexico: 590, 25 deaths) — WHO. In U.S.: 245 confirmed U.S. cases in 35 states. — CDC.

“We might be entering an Age of Pandemics… a broad array of dangerous emerging 21st-century diseases, man-made or natural, brand-new or old, newly resistant to our current vaccines and antiviral drugs…. Martin Rees bet $1,000 that bioterror or bioerror would unleash a catastrophic event claiming one million lives in the next two decades…. Why? Less forest, more contact with animals… more meat eating (Africans last year consumed nearly 700 million wild animals… numbers of chickens raised for food in China have increased 1,000-fold over the past few decades)… farmers cut down jungle, creating deforested areas that once served as barriers to the zoonotic viruses…” — Larry Brilliant, Wall Street Journal

The ‘Sustainability Solution’ to the Fermi Paradox

Posted by in categories: human trajectories, space, sustainability

Jacob Haqq-Misra and Seth D. Baum (2009). The Sustainability Solution to the Fermi Paradox. Journal of the British Interplanetary Society 62: 47–51.

Background: The Fermi Paradox
According to a simple but powerful inference introduced by physicist Enrico Fermi in 1950, we should expect to observe numerous extraterrestrial civilizations throughout our galaxy. Given the old age of our galaxy, Fermi postulated that if the evolution of life and subsequent development of intelligence is common, then extraterrestrial intelligence (ETI) could have colonized the Milky Way several times over by now. Thus, the paradox is: if ETI should be so widespread, where are they? Many solutions have been proposed to account for our absence of ETI observation. Perhaps the occurrence of life or intelligence is rare in the galaxy. Perhaps ETI inevitably destroy themselves soon after developing advanced technology. Perhaps ETI are keeping Earth as a zoo!

The ‘Sustainability Solution’
The Haqq-Misra & Baum paper presents a definitive statement on a plausible but often overlooked solution to the Fermi paradox, which the authors name the “Sustainability Solution”. The Sustainability Solution states: the absence of ETI observation can be explained by the possibility that exponential or other faster-growth is not a sustainable development pattern for intelligent civilizations. Exponential growth is implicit in Fermi’s claim that ETI could quickly expand through the galaxy, an assumption based on observations of human expansion on Earth. However, as we are now learning all too well, our exponential expansion frequently proves unsustainable as we reach the limits of available resources. Likewise, because all civilizations throughout the universe may have limited resources, it is possible that all civilizations face similar issues of sustainability. In other words, unsustainably growing civilizations may inevitably collapse. This possibility is the essence of the Sustainability Solution.

Implications for the Search for Extraterrestrial Intelligence (SETI)
If the Sustainability Solution is true, then we may never observe a galactic-scale ETI civilization, for such an empire would have grown and collapsed too quickly for us to notice. SETI efforts should therefore focus on ETI that grow within the limits of their carrying capacity and thereby avoid collapse. These slower-growth ETI may possess the technological capacity for both radio broadcasts and remote interstellar exploration. Thus, SETI may be more successful if it is expanded to include a search of our Solar System for small, unmanned ETI satellites.

I Don’t Want To Live in a Post-Apocalyptic World

How About You?
I’ve just finished reading Cormac McCarthy’s The Road at the recommendation of my cousin Marie-Eve. The setting is a post-apocalyptic world and the main protagonists — a father and son — basically spend all their time looking for food and shelter, and try to avoid being robbed or killed by other starving survivors.

It very much makes me not want to live in such a world. Everybody would probably agree. Yet few people actually do much to reduce the chances of of such a scenario happening. In fact, it’s worse than that; few people even seriously entertain the possibility that such a scenario could happen.

People don’t think about such things because they are unpleasant and they don’t feel they can do anything about them, but if more people actually did think about them, we could do something. We might never be completely safe, but we could significantly improve our odds over the status quo.

What should be at the center of the U.S. stimulus package

Posted by in categories: existential risks, geopolitics, habitats, lifeboat, space, sustainability

The projected size of Barack Obama’s “stimulus package” is heading north, from hundreds of billions of dollars into the trillions. And the Obama program comes, of course, on top of the various Bush administration bailouts and commitments, estimated to run as high as $8.5 trillion.

Will this money be put to good use? That’s an important question for the new President, and an even more important question for America. The metric for all government spending ultimately comes down to a single query: What did you get for it?

If such spending was worth it, that’s great. If the country gets victory in war, or victory over economic catastrophe, well, obviously, it was worthwhile. The national interest should never be sacrificed on the altar of a balanced budget.

So let’s hope we get the most value possible for all that money–and all that red ink. Let’s hope we get a more prosperous nation and a cleaner earth. Let’s also hope we get a more secure population and a clear, strategic margin of safety for the United States. Yet how do we do all that?

Why antropic principle stops to defend us

Posted by in categories: existential risks, futurism, space

In the volume “Global catastrophic risks” you could find excellent article of Milan Circovic “Observation selection effects and global catastrophic risks”, where he shows that we can’t use information from past records to estimating future rate of global catastrophes.
This has one more consequence which I investigate in my article: “Why antropic principle stops to defend us. Observation selection, future rate of natural disasters and fragility of our environment” — that is we could be in the end of the long period of stability, and some catastrophes may be long overdue and what is most important we could underestimate fragility of our environment which could be on the verge of bifurcation. It is because origination of intellectual life on the Earth is very rare event and it means that some critical parameters may lay near their bounds of stability and small anthropogenic influences could start catastrophic process in this century.…vironment–

Giant planets ignition

Posted by in categories: biotech/medical, existential risks, futurism, geopolitics, nanotechnology, nuclear weapons, rants, space

I wrote an essay on the theme of the possibility of artificial initiation and fusion explosion of giants planets and other objects of Solar system. It is not a scientific article, but an atempt to collect all nesessary information about this existential risk. I conclude that it could not be ruled out as technical possibility, and could be made later as act of space war, which could clean entire Solar system.

Where are some events which are very improbable, but which consequence could be infinitely large (e.g. black holes on LHC.) Possibility of nuclear ignition of self-containing fusion reaction in giant planets like Jupiter and Saturn which could lead to the explosion of the planet, is one of them.

Inside the giant planets is thermonuclear fuel under high pressure and at high density. This density for certain substances is above (except water, perhaps) than the density of these substances on Earth. Large quantities of the substance would not have fly away from reaction zone long enough for large energy relize. This fuel has never been involved in fusion reactions, and it remained easy combustible components, namely, deuterium, helium-3 and lithium, which have burned at all in the stars. In addition, the subsoil giant planets contain fuel for reactions, which may prompt an explosive fire — namely, the tri-helium reaction (3 He 4 = C12) and for reactions to the accession of hydrogen to oxygen, which, however, required to start them much higher temperature. Substance in the bowels of the giant planets is a degenerate form of a metal sea, just as the substance of white dwarfs, which regularly takes place explosive thermonuclear burning in the form of helium flashes and the flashes of the first type of supernova.
The more opaque is environment, the greater are the chances for the reaction to it, as well as less scattering, but in the bowels of the giant planets there are many impurities and can be expected to lower transparency. Gravitational differentiation and chemical reactions can lead to the allocation of areas within the planet that is more suitable to run the reaction in its initial stages.

The stronger will be an explosion of fuse, the greater will be amount of the initial field of burning, and the more likely that the response would be self-sustaining, as the energy loss will be smaller and the number of reaction substances and reaction times greater. It can be assumed that if at sufficiently powerful fuse the reaction will became self-sustaining.

Apophis Asteroid still a risk for 2036

Posted by in categories: asteroid/comet impacts, defense, existential risks, space

On April 16, 2008, NASA News Release 08–103 reaffirmed that its estimation of a 1 in 45,000 chance of impact in 2036 remains valid.

The B612 Foundation is working towardcs the goal of of significantly altering the orbit of an asteroid in a controlled manner by 2015.

the B612 Foundation made estimates of Apophis path if a 2036 Earth impact were to occur.

The impact result is a narrow corridor called the ‘risk corrider’ which would be a few miles wide. Countries estimated to be in the direct path:

The Heirs of Prometheus

Posted by in categories: human trajectories, space

Crossposted from the blog of Starship Reckless

Note: Like anyone who’s breathing, I have been tracking the Phoenix Lander. So I thought this might be a good moment to share a personal memory of one of its ancestors. That one did not survive to fulfill its mission, but the dream stayed alive. What I said then is even more true today, almost a decade later. The Greek version of this article was published in the largest Greek daily, Eleftherotypia (Free Press).
