Institutionalized insanity versus intelligent thinking – a reflection.
This appeared on Patrice’s Blogsite on January 11th and is republished with his very kind permission. You may want to bookmark Patrice’s blogsite, which is here. The sub-heading of his blog is ‘Intelligence at the core of humanism‘ and, trust me, that is not an overstatement of the wisdom that is contained within his blog, as the following nobly illustrates.
Aphorism January 2012
Species Shifting North, Intelligence Left Behind:
Nothing like raw numbers. In the last twenty years, Europe warmed up by one degree Celsius (about 2 degrees in the primitive, less meaningful Fahrenheit system). That’s equivalent to a thermal shift of 249 kilometers north.
Insects responded by an average shift north of 114 kilometers, and birds by only 33 kilometers. This is creating imbalances (fully obvious in Alaska, and high altitude North America, where the insects move faster than their predators, killing entire forests, which then burn).
This differential adaptation also illustrates an important point the stupid partisans of the “market” always neglect: being more intelligent can make you slower. Birds are more intelligent than insects, so they find harder to leave their families, friends, habits, and landscapes they are familiar with behind. (No, I will not say that insects are more like Americans, driven by the market, and birds more like Europeans, driven also by broader values. I shall resist, lest I move too fast, like an insect, and outrage part of my brainy readership…)
Thus, as the market dominates, so does the stupid.
Adaptation is not always a manifestation of intelligence, and inadaptation often a sign of intelligence. A well known experience is to put a fly, or a bee, inside an open bottle, with a light source opposed to the opening. The bee will search intelligently the bottom of the bottle, where the exit ought to be. The less intelligent fly will buzz around stupidly, and exit first.
It’s no wonder that the partisan of the markets, who are richer and thus more influential, are for something stupid, as they are faster, precisely because they are more stupid, with fewer values, besides the colossal greed which dominates their psyche. So there is a non linear vicious loop, the more the market dominates.
Thus, next year the candidate historically financed by Wall Street will confront the extremely wealthy businessman cum politician, son of his father, also a governor cum businessman. Market against market: the market should not lose. The birds will be left behind by the fast moving insects, once again. Change you can’t believe in.
Where is everybody?
“Lord” (!) Martin Rees, “Astronomer Royal”, Nobel laureate, etc., complete with pretty pictures and beautifully spooky music, speculates it’s teeming with aliens out there.
But as Enrico Fermi quipped:”Where is everybody?“
The situation is not helped by us understanding very little about what the universe is made of. In the latest numbers I saw the universe was made 4% conventional matter, and the rest was… Dark. Mostly Dark Energy, with some Dark Matter. Who said the Dark Side was not important?
There are no dominant theories of what the Darkness is made of.
CERN should be able to find stuff below its energy reach. So far, nothing.
We have detected more than 150 planets. It seems one star out of ten, at least, has planets. Some have been detected in the habitable zone, where liquid water is found. But the water has to be continuously present for billions of years. Continuously (which did not happen on Mars and Venus).
400 billion stars in our galaxy. The big question is how many planets can harbor advanced (=oxygen breathing) life. No inkling of that. There are plenty of planets out there, indeed, but most hostile to life. So far. How Much Intelligent Life Out There? On Earth, it took 1.5 billion years to go from advanced life to intelligent, civilized life. A lot of things can go wrong in 1.5 billion years.
That advanced life did not develop on Mars or Venus is not an accident: although on the outskirts of the habitable zone, either planet did not have what it took. Mars was too small, and, just like Venus was not protected by a powerful plate tectonic, with accompanying magnetic field, among other problems (so the solar wind blowing the top of the atmosphere stole the hydrogen, hence water, etc.)
My hunch is that most planets in the hospitable zone, when found, will be bereft of advanced life, although primitive life may be quite frequent. Reason? Too many miracles at work for billions of years in the solar system. Especially in light of what we find out there (We see plenty of Jupiter size planets in close orbits around their suns, presumably after sweeping their entire system clean; OK, that’s partly a result of the method used to find planets presently, but the fact is, we find such situations aplenty! The presence of Jupiter out there, as our guardian protecting Earth from comets looks quite miraculous…)
If You Want To Save the Biosphere, Push Tech:
Some people in the Netherlands have suggested building an artificial mountain. It’s feasible, and would be smart to do, not just there, but say in a place such as Saudi Arabia (technical variations on the theme could collect water, as in cloud, or fog forests found in California or Peru).
Another point is that artificial mountains could help protect biological diversity from the greenhouse heating. Cynics would point out that it would take an enormous amount of energy to build them. True, with present tech, and the energy would be dirty too, presently. But that would be another motivation to go green. Green and big.
Most wind-driven energy system in Europe? Denmark. Most CO2 polluting country in Europe? Denmark. Coal power plants pick up the slack when the wind falters. Another case where nuclear offers its smiling face. Future nuclear that is. Not your great grandfather’s nuclear. Past nuclear tech should be terminated, just like coal. However, there are 100 unexploited, un-researched nuclear energies out there, and only those with insignificant waste will be acceptable. (Nobody would accept a fossil fuel system where only 2% of the fuel would be burned, and the rest allowed to pollute all over!)
Reminder: as the greenhouse heating proceeds, winds will falter because the heat differential between poles and equator will sink, thus shutting down that thermal engine known as the atmosphere (yes, hurricanes will be rarer, but fiercer).
Institutionalized insanity Versus Thinking Right:
In Switzerland a nuclear plant was built one kilometerdownstream from a dam, along the same river. None of those two could resist the sort of very strong quake happening occasionally in the Alps. A flood cum nuclear explosion is entirely imaginable. This sort of insanity has nothing to do with nuclear power, it has everything to do with lack of intelligence.
This is all the more strange since some Swiss cantons such as Valais get 20% of their GDP from research. By the way themedical drug sector part of GDP is twice the banking sector in Switzerland. For those who wonder why Switzerland is so rich (the same holds for Sweden and other Nordic company). It’s not (just) about the banks.
(More) Direct Democratic Keeps Bankers At Bay:
The weight of direct democracy has forced Swiss banks into reserve requirements twice those of the future Basel III regulations. (In other words, banks are many times tamer in Switzerland than in the USA, if one uses reserve requirements enforced as a measuring device; Basel III does not cover most of the enormous derivative trading, though.)
The scandal of the central banker heading the Swiss Central Bank buying dollars days before taking the decision of making the dollar explode up against the Swiss franc keeps unfolding. Yes, he knew about the trades, and yes, he had days to stop them afterwards.
It is dawning over Swiss society that those with privileged information should not be legally allowed to exploit them. The whole planet has to follow down that line. But, although it has been obvious for years that American and European politicians and central bankers are rich from insider trading, nothing has been done. Yet.
The Plutocrats Cash Out And Shame Does Not Count:
What looked to me as the immensely stupid and arrogant wife of the Swiss Bank President, explained herself from Singapore, where she owns an art gallery. If she really wanted to make real money out of her husband’s job, she knew how to do it, she asserted confidently. And there she was going through a list (a), b), c), d), etc… of things she would have done if she wanted to make more than the measly $75,000 she made. And how to make them secretly, she insisted.
Her name is “Kashya”, appropriately pronounced “Cashia”. In this case, Cashia said, in her native American English, they were in a rush, because they just had some cash from selling a chalet to store, so that is why she hid nothing. That brings a few questions, such as whether she is used to exploit the mechanisms of further cheating she explicated so adroitly on TV. The central banker, the plutocrat Hildebrand, having resigned, will get a million dollar salary in the next year, from the People, while his fellow plutocrats will rush to propose him a much more protitable conspiracy to join. I propose to put him in jail, instead.
Another Claim Of Mental Decline. And The Agenda Behind It: There Is No Good Wisdom, Except Dead Wisdom, Say Plutocrats:
Supposedly some new test showed a decline in “cognitive capabilities” starting at age 45. Apparently people were asked to remember lists of words starting with some particular letters. It does not seem to have come to the mind of the experimenters that maybe older brains do not like to remember such stupid stuff.
Thinking means motivating. Without the right motivation, there is not the right thinking.
In the case of “IQ”, a decline is observed at 24, some say… Military officers would concur that it is better to send 18 year olds to die, because they are bright enough to execute orders well, but not so bright that they would know that they might die for no good reason.
A related point: no doubt a two-year old training to go potty remembers very well each time she goes. Whereas an adult tends to lose this facility of neurological retention for this sort of event. One generally observes. But it is not because adults have suffered mental decline that they do not remember every poop. Simply, they have seen lots of poop passing by.
Actually the argument can be made that consciousness and conscious memorization are needed to deploy automatisms, but once those are in place, they are not needed anymore, and so consciousness, and conscious recall should not be present.
When I was a young driver, I remembered everything I did when driving a car, but now I do it automatically, remembering very few of my gestures. When driving, my consciousness is mostly watching for the unforeseen.
Is there a political interpretation explaining such mental declines claims? Indeed, there is. As people get older, they elaborate higher wisdom. Thus, although the soldiers of revolution are typically very young people, because they have their aggression hormones less tempered by wisdom, the leaders of revolution are typically much older.
Let me explain this carefully: fascist and plutocratic leaders typically claim that they are “conservatives“. It means that they justify their mean rule by a refusal to adapt to changed circumstances.
As the French revolution stirred, the most esteemed leaders were senior citizens such as Voltaire or Benjamin Franklin, and everybody looked up to them, from Louis XVI to Turgot; on the Dark Side, many of the leaders, such as the Comte d’ Artois, were barely teenagers.
Closer to us, in WWII, the SS seduced many a 16 year old. In the last few weeks of the war, many of the most enraged Nazis fighting to the bitter end with the allies in the mountainous heart of Germany were school children with heavy weapons. In more than one case, disgusted American GIs, reluctant to blow up some more enraged children to bits, sent their school mistresses to negotiate with them!
If the (plutocratic) establishment can claim that revolutionary wisdom is actually the fruit of mental decline, presto, no revolution. It will be “conservatism” all the way.
Why Do We Want To Always Support Winners?
Supporting the home team is easy to understand: this is the tribal instinct. Human beings are social, they have to love the group, thus dislike what hinders the group, namely, other groups.
One has to love the leader(s) of the group, the alpha(s). In general, to abate social tensions, an instinct has got to exist, which makes the oppressed love the oppressor, or let’s say, the inferior love the superior. or even love the winning group, to be motivated to join it. Something more plausible to females. Hence Beatlemania.
If One Wants Happiness, One Should Prepare For The Worst:
Pe Romaneste: So happiness must be an accident.
Alexi Helligar: There seems to be greater power in the accidental than we imagine.
Patrice Ayme: Indeed, to a great extent, everything is accidental. Realizing this means that those who complain that something happened accidentally, and, thus, was not expected, have not understood the first thing about causality. Accidents is how the world happens. Wisdom consists in anticipating their occurrence, and having a plan B, should they occur.
Brutality Is Friendly To Plutocracy, Long Life Friendly To Wisdom:
Only wisdom can allow long life. Really very long life, lasting centuries, for individuals or civilization. Short lives are brutish, and this has the consequence in many a perpetrator, to spurn whatever life is offered. Indeed a good way to spurn something is by devaluing it. The brutality of the human condition is self reinforcing…
This why human life extension is a necessity, a preliminary, for the extension of wisdom. Because as long as lives are short and brutish, the short and brutish way of life is all too optimal, for all too many people (although those with children, or grandchildren they love will disagree, but they are not necessarily a majority).
This is something that life spurning plutocrats such as Mr. Jobs have been busy not understanding, as brutality is their friend.
Plutocrats Love Death Indeed:
Steve Jobs, despite leaving Reed College after six months, was asked to give the 2005 commencement speech at Stanford. Why? Did Jobs invent anything important? (Disclosure: My Mom offered me an ultra light Mac Air, and I love it.) No, he was just an artistic technology integrator, but not necessarily as mechanically oriented as a car mechanic (his partner Wozniak was the programmer, but even this one finished his college studies in computer science, 20 years later, at Berkeley, and found them hard!)
In his Stanford address, delivered after Mr. Jobs was told he had cancer, but before it was clear that it would ultimately claim his life, Mr. Jobs told his mesmerized audience of naive sheep that “death is very likely the single best invention of life. It is life’s change agent.”
In this light, the invasion of Iraq by Bush and his fanatical followers made sense: by visiting more than one million deaths upon Iraq, the USA brought the single best invention of life. Everybody, or more exactly 83%, including a majority of Stanford students, agreed, at the time.
Is this love of death why Jobs refused conventional medical treatment initially, until it was too late? Jobs insisted that the benefit of death, is you know not to waste life living someone else’s choices. I guess that extended to the medical.
Verily, death came first, and was denied by life. Life is the denial of death. Life did not have to invent death.
Hormuz Crisis Versus Suez Crisis: Spot The Difference!
Why did the USA not get upset when Nasser seized the Suez canal, in 1956? And actually why did the USA instead use the occasion to threaten Israel, Britain and France? Not just that, butpresident Eisenhower aligned himself with the Egyptian, and Soviet dictators. The Soviets, while invading Hungary, killing at least 40,000 Hungarians, threatened to atom bomb London and Paris. With the loud acquiescence of the USA… Which got France and Britain, not the mass murderous USSR, condemned at the United Nations’ general Assembly. What a crazy week it was.
And now, 55 years later, lo and behold, the USA is getting all upset as Iran wants to stop what’s going on below its nose in the strait of Hormuz? Just asking. Inquiring minds want to know.
Is it that in 1956, France and Britain were viewed as preys of the USA? And now that the USA has grabbed everything from France and Britain, they want to be friends again? Because the rich need servants, maybe? In any case, the Suez Crisis was an incongruous reminder that, in 1939, the USA was allied with the USSR and Nazi Germany, against France and Britain (oopss, something one should never say!)
And my advice would be to be very careful with Hormuz. If one wants long life, one does not want long wars. And one does not want fossil fuels. The sooner we get rid of fossil fuels, the better, and if Hormuz helps that way, so be it. The messy Iranian theocracy will not win a waiting game.
No Change, No Life!
What the USA needs to do is to do what all serious countries do, and have always done: change its constitution, since the changed circumstances require it.
Cool Is Not Cool:
“Cool”. Why is “cool” such a popular word? Is it supposed to correspond to an attitude? Is it a mark of, and a tool for, our subjugation?
So Obama is confronted to the greatest financial thievery in the history of civilization, and that leaves him “cool“? Having rebooted the perpetrators with public money he goes to them to ask for a billion to campaign for re-election? Cool? I mean: we are not supposed to blow our tops when we contemplate such injustice in the name of change we can’t believe?
In Europe, pretty amazingly intricate financial and semantic engineering is presently deployed to save the banks and the sovereign states entangled with them. There again the bottom line is that the resources of the countries are deployed for the exclusive enjoyment of the few, who happen to be the greatest swindlers ever. Although they are presented as too big to flay.
Actually the same technique as in the USA, Quantitative Easing, is being deployed, and on a similar scale. But, as the head of the European Central Bank, an ex Goldman Sachs partner, pointed out sardonically, a scornful smile on the corner of his mouth, Europeans use a different semantic: they don’t call it Quantitative Easing.Therein the difference. Is not that cool too?
Is the greenhouse effect already that bad that cool is the ultimate state one ought to strive for with all of one’s being? Or are we supposed to reject our mammalian inheritance? Mammals, by being warmer, could do more. So, when climate change happened 65 million years ago, they survived (so did the very warm birds, who evolved from bird-like dinosaurs). Are we supposed to do less now, and not survive? Or then survive like crocs, deep in the mud, super cool, eating carrion?
Is “cool” imposed on us so that people know no higher emotional state than iguanas? Become cool like barnacles, as we cling to the existence the plutocrats condescend to leave us to enjoy? Being so cool we would not be like the American and French hot heads who came forth with new constitutions in 1789?
So is the celebration of “cool” what forces us to not be outraged, as plutocrats steal and burn the entire planet to forget about their megalomaniac angst? To forget they are just crazy critters in need of some restraint? Is “cool” the state slaves are supposed to be in to optimize the enjoyment of their masters? Is it only cool to be cool like corpses?
France anti-genocide law denounced by Turkey:
Now this is hilarious. France passed a law punishing convicted holocaust deniers by up to one year in jail and 45,000 euros fine.
Fine, indeed. Who would turn into a partisan, a defender of holocausts? Is not holocaust denial a form of hate speech? Holocausts remain a problem, because when one has killed most of a human group, there is nearly nobody to complain on their behalf: other people move on, as herbivores do, once one of them has been seized and devoured.
France’s national Assembly passed the anti-genocidal law, with bipartisan support. And what do you think happened?
Erdogan, the three time elected Prime Minister of Turkey, had a fit: how does France dare make holocaust denial a crime? He forbade French fighter jets to land in Turkey (so I guess the no fly zone over Syria will be delayed), recalled the Turkish ambassador to France, and stopped all talks with France.
And the questions are: why does the present government in Turkey love holocausts so much? Are holocaust such an endangered species that Turkey has to protect them with all its might?
Why does Turkey consider that a general attack against holocausts is an attack against Turkey? Is it because holocausts are intrinsic to the Turkish character? Or is it because holocausts are mentioned positively in the Bible and the Qur’an, and the present Turkish government is obsessed with the religion of the child molester Abraham? Is this why Erdogan is angry?
We Are Truth Machines.
That monkeys now build cities has not changed that truth. No hallucination added in the last 6,000 years has changed that truth either. Science is what we do, and what stands in the way of that fundamental truth, faces extermination.
Neither too close nor too far from the Sun.
Towards the end of the lecture that Lord Martin Rees gave at University of Melbourne’s Medical School in 2010, he spoke of the way that Planet Earth has warmed up these last 100 years, warmed up uniquely. Why the word ‘uniquely’? Because, for the first time in the ancient life of our planet, that warming is the result of the activity of a life species living on that planet; mankind. It’s difficult to comprehend how special, how fragile and, therefore, how vulnerable is mankind’s ability to survive on Planet Earth. That’s why a recent item on Martin Lack’s excellent blogsite Lack of Environment is published on Learning from Dogs with Martin’s kind permission. But first let me quote a little from WikiPedia about the ‘goldilocks principle’,
In astronomy and astrobiology, the habitable zone is the region around a star where a planet with sufficient atmospheric pressure can maintain liquid water on its surface.1 Since liquid water is essential for all known forms of life, planets in this zone are considered the most promising sites to host extraterrestrial life. The terms “ecosphere” and “Liquid Water Belt” were introduced by Hubertus Strughold and Harlow Shapley respectively in 1953. Contemporary alternatives include “HZ”, “life zone”, and “Goldilocks Zone.”
“Habitable zone” is sometimes used more generally to denote various regions that are considered favorable to life in some way. One prominent example is the Galactic habitable zone’ (the distance from the galactic centre). Such concepts areinferred from the empirical study of conditions favorable for life on Earth. If different kinds of habitable zones are considered, their intersection is the region considered most likely to contain life.
The location of planets and natural satellites (moons) within its parent’s star’s habitable zone (and a near circular orbit) is but one of many criteria for planetary habitability and it is theoretically possible for habitable planets to exist outside the habitable zone. The term “Goldilocks planet” is used for any planet that is located within the CHZ although when used in the context of planetary habitability the term implies terrestrial planets with conditions roughly comparable to those of the Earth(i.e. an Earth analog). The name originates from the story of Goldilocks and the Three Bears, in which a little girl chooses from sets of three items, ignoring the ones that are too extreme (large or small, hot or cold, etc.), and settling on the one in the middle, which is “just right”. Likewise, a planet following this Goldilocks Principle is one that is neither too close nor too far from a star to rule out liquid water on its surface. While only about a dozen planets have been confirmed in the habitable zone, the Kepler spacecraft has identified a further 54 candidates and current estimates indicate that there are “at least 500 million” such planets in the Milky Way.
So now to Martin Lack’s post.
Goodbye Goldilocks Planet?
Is it time to say goodbye to the Goldilocks Planet?
I hope not, because the next-nearest one yet discovered is 600 light years away! However, if we are indeed now passing a tipping point (i.e. as the widespread rapid thawing of Siberian permafrost suggests) both mitigation and adaptation will be almost impossible. Therefore, if we cannot reverse the damage already done (i.e. how can we make permafrost re-freeze or reverse the retreat of mountain glaciers?), we may have to accept that temperatures will eventually rise to a level at which the Antarctic first became glaciated 35 million years ago; and that sea levels will now rise continuously for several centuries – making any permanent settlement anywhere near the coast impossible (seeJames Hansen in Storms of my Grandchildren).
If your response to all this is to accuse me of being alarmist, all I can say is that I am afraid denial is definitely not a good evolutionary survival mechanism. Furthermore, as American high school science teacher – and now climate change activist – Greg Craven has said,“Unfortunately, the experiment is already running; and we are all in the test-tube!” I believe we must therefore hope that humanity will not repeat the folly of the former inhabitants of Easter Island; who chopped down all their trees for firewood and allowed all the decent soil to be washed away so they could not grow anything.
I think it is fair to say that 2011 was a difficult year for humanity and the planet; and 2012 could be worse. We now seem to be facing both a financial and an environmental crisis: Even at the tender age of 46, I can appreciate that the prospect of 6 years of austerity measures (here in the UK) is completely without precedent; worse even than the great depression of the 1920s. In the UK, public sector workers have been demanding a better pension! What about a better economic system, or even a better planet? If necessary, please forgive my impertinence but, how can people demand justice for themselves whilst ignoring all the injustices we are inflicting on those least able to adapt; and/or bequeathing to our descendants?
This is almost as pessimistic as my recent answer on ClimateSight to the question “Why are people who want to reduce – and possibly eliminate pollution – and create a safer world, considered obstructionist naysayers?“, which is… “If everyone lived as we do in ‘the West’, the planet’s ecological carrying capacity would only be about 3 billion [Paul and Anne Ehrlich (1996)]. Therefore we cannot solve poverty without allowing a lot of people to die or by wealthy people agreeing to moderate their over-consumption of the Earth’s resources. Sorry to be so blunt but, this is the simple answer to the question.” …Despite what detractors say this is not misanthropic eco-Socialism, it is reality. There is not enough decent farmland and/or resources of every kind for 7 billion people or more to live like we currently do in ‘the West’. If we are not going to deny the legitimate aspirations of poorer peoples to attain a better standard of living, we will have to moderate our over-consumption and/or pollution of the Earth’s resources. We cannot have it both ways.
If we continue to burn all the Earth’s fossil fuels – just because they are there and because we can – we will most certainly have to say good bye to our Goldilocks Planet. However, now that we know that what we are doing is causing the problem, would it not be a good idea to stop doing it? You know: When in a hole, stop digging, etc… As the Good Book says, “As a dog returns to its vomit, so a fool repeats his folly” (Proverbs 26:11).
Suggested New Year’s Resolution:
If we want things to change, I believe we must acknowledge that Clive Hamilton is right: climate change is a failure of modern politics – representative democracy is not working! Therefore, we must all take a much more active role in the process of government – this is called participatory democracy – and we must start by demanding that our politicians dismantle (or at least stop being misled by) the fossil fuel lobby who do not want their business as usual programme interrupted.
Having said all that, I would still like to sincerely wish you all the best for 2012 (although I hope the Mayan Calendar is wrong).
Big shift of topic from yesterday!
Yesterday, I wrote about the fabulous success of the British otter having gone from the crumbling edge of extinction to now being found in every English county.
Aliens may destroy humanity to protect other civilisations, say scientists
Rising greenhouse emissions could tip off aliens that we are a rapidly expanding threat, warns a report
It may not rank as the most compelling reason to curb greenhouse gases, but reducing our emissions might just save humanity from a pre-emptive alien attack, scientists claim.
Watching from afar, extraterrestrial beings might view changes in Earth’s atmosphere as symptomatic of a civilisation growing out of control – and take drastic action to keep us from becoming a more serious threat, the researchers explain.
This highly speculative scenario is one of several described by a Nasa-affiliated scientist and colleagues at Pennsylvania State University that, while considered unlikely, they say could play out were humans and alien life to make contact at some point in the future.
Shawn Domagal-Goldman of Nasa’s Planetary Science Division and his colleagues compiled a list of plausible outcomes that could unfold in the aftermath of a close encounter, to help humanity “prepare for actual contact”.
In their report, Would Contact with Extraterrestrials Benefit or Harm Humanity? A Scenario Analysis, the researchers divide alien contacts into three broad categories: beneficial, neutral or harmful.
Beneficial encounters ranged from the mere detection of extraterrestrial intelligence (ETI), for example through the interception of alien broadcasts, to contact with cooperative organisms that help us advance our knowledge and solve global problems such as hunger, poverty and disease.
Another beneficial outcome the authors entertain sees humanity triumph over a more powerful alien aggressor, or even being saved by a second group of ETs. “In these scenarios, humanity benefits not only from the major moral victory of having defeated a daunting rival, but also from the opportunity to reverse-engineer ETI technology,” the authors write.
Other kinds of close encounter may be less rewarding and leave much of human society feeling indifferent towards alien life. The extraterrestrials may be too different from us to communicate with usefully. They might invite humanity to join the “Galactic Club” only for the entry requirements to be too bureaucratic and tedious for humans to bother with. They could even become a nuisance, like the stranded, prawn-like creatures that are kept in a refugee camp in the 2009 South African movie, District 9, the report explains.
The most unappealing outcomes would arise if extraterrestrials caused harm to humanity, even if by accident. While aliens may arrive to eat, enslave or attack us, the report adds that people might also suffer from being physically crushed or by contracting diseases carried by the visitors. In especially unfortunate incidents, humanity could be wiped out when a more advanced civilisation accidentally unleashes an unfriendly artificial intelligence, or performs a catastrophic physics experiment that renders a portion of the galaxy uninhabitable.
To bolster humanity’s chances of survival, the researchers call for caution in sending signals into space, and in particular warn against broadcasting information about our biological make-up, which could be used to manufacture weapons that target humans. Instead, any contact with ETs should be limited to mathematical discourse “until we have a better idea of the type of ETI we are dealing with.”
The authors warn that extraterrestrials may be wary of civilisations that expand very rapidly, as these may be prone to destroy other life as they grow, just as humans have pushed species to extinction on Earth. In the most extreme scenario, aliens might choose to destroy humanity to protect other civilisations.
“A preemptive strike would be particularly likely in the early phases of our expansion because a civilisation may become increasingly difficult to destroy as it continues to expand. Humanity may just now be entering the period in which its rapid civilisational expansion could be detected by an ETI because our expansion is changing the composition of the Earth’s atmosphere, via greenhouse gas emissions,” the report states.
“Green” aliens might object to the environmental damage humans have caused on Earth and wipe us out to save the planet. “These scenarios give us reason to limit our growth and reduce our impact on global ecosystems. It would be particularly important for us to limit our emissions of greenhouse gases, since atmospheric composition can be observed from other planets,” the authors write.
Even if we never make contact with extraterrestrials, the report argues that considering the potential scenarios may help to plot the future path of human civilisation, avoid collapse and achieve long-term survival.
I am bound to say that if Mr Domagal-Goldman and his colleagues believe that spending time and money on the possible outcomes of contact with extraterrestrials is a good idea in these present times then I am minded about those other visitors from outer space who passed Planet Earth by because there were no signs of intelligent life!
Here’s Alex Jones on the topic …
THE UNIVERSE TEACHES AWE AND HUMILITY
This is a guest post from an old friend of Learning from Dogs, Patrice Ayme. Patrice writes his own Blog here and this article is published with gratitude and with awe! If you can, because the article more than deserves this, find somewhere quiet for half-an-hour to read this – it may well change the way you think about everything.
Theme: Is there extraterrestrial life? Extraterrestrial intelligence? A related question: how big is the universe? On all these subjects considerable and very surprising progress is in the making. I describe some of the new ideas and facts in plain language, from Plate Tectonics to Cosmic Inflation.
Facing the enormity of it all, honest minds will find honor and pleasure in telling the truth, and nothing but the truth (carefully distinguishing it from hope we can believe in). Some physicists, searching for the limelight, have presented some science fiction, or some science fantasy, or let’s say scientific working hypotheses, philosophically grounded, as real, established science. This is misleading and dangerous: science is truth, and that is why the public supports it. Let’s keep it that way.
Sometimes all that science does, but that is fundamental, is to find new uncertainties we did not previously suspect. A basic humility that needs to be taught to people and politicians is that knowledge is not just about learning what we know, but also about learning that there are new dimensions to what we don’t know.
One certainty: our Earth is rare and fragile. Earth was a primordial deity of the Greeks, Gaia, viewed as female, nourishing humankind. Gaia is an on-going miracle, of self regulation, with extremely complicated biology and physics entangled. The more we observe the cosmos, the more we see that’s hell out there. Gaia is a rare deity, Pluto is the rule. Here are some inklings.
ALIEN SOLAR SYSTEMS EVERYWHERE:
Many planets have been discovered around many stars. Solar systems (= several planets orbiting the same star) have also been discovered. In one of these systems three planets around a dwarf red star are all in the inhabitable zone (= neither too cold nor too hot, so that liquid water exists on a planet there). One of them is smack in the middle of the balmy zone. It seems clear that most stars will be found to have planets (we are above 30%, and our present detection methods are very crude).
Still there does not seem to be many civilizations out there. As Enrico Fermi put it:”Where is everybody?”
Far enough from the dangerous galactic center, with its zooming stars, high radiation, and gigantic black hole, but not far enough to miss the full wealth of the periodic table, with its many elements, there is a narrow band all around the galaxy, the inhabitable zone, with at least 50 billion suns (within the trillion suns of the Milky Way).
Everything indicates that there are billions of colonizable planets in the inhabitable zone of our galaxy: colonialism has a great future (once we find how to get there). Life could have started on many of these planets. But on most of these, it was quickly annihilated: hellish, incandescent “super-earths” (= rocky planet with masses up to 10 times Earth) ready to fall into their star, abound.
INGREDIENTS FOR LIFE: MAGNETOSPHERE, TECTONICS, MOON…
The obvious candidate for the start of life is next door. It is Mars (Venus may have qualified too, the early Sun being 25% weaker; but Venus has long turned into hell, destroying all biological remnants). Everything indicates that life started on Mars. It would be very surprising that it did not.
Probably even OUR life started there. Impacts of asteroids and comets would have thrown living material from Mars to Earth. Mars meteorites have been found in Antarctica, lying on the ice. It has been observed that the temperatures within a Mars meteorite could stay very low: no more than around 40 Celsius, during the entire Mars-Earth transfer.
The Earth stayed too hot for life much longer than Mars, due to its much greater thermal inertia, large, intense radioactive core, greater number of impacts, and having thoroughly melted after the giant impact which created our life fostering Moon.
But then, after an auspicious start, Mars lost most of most of its atmosphere (probably within a billion years or so). Why? Mars is a bit small, its gravitational attraction is weaker than Earth (it’s only 40%). But, mostly, Mars has not enough a magnetic field. During Coronal Mass Ejections, CMEs, the Sun can throw out billions of tons of material at speeds up to and above 3200 kilometers per seconds. It’s mostly electrons and protons, but helium, oxygen and even iron can be in the mix.
The worst CME known happened during the Nineteenth Century, before the rise of the electromagnetic civilization we presently enjoy. Should one such ejection reoccur now, the electromagnetic aspect of our civilization would be wiped out.It goes without saying that we are totally unprepared, and would be very surprised. Among other things, all transformers would blow up, and they take months to rebuild. we would be left with old books in paper, the old fashion way. A CME can rush to Earth in just one day. (Fortunately the Sun seems to be quieting down presently, a bit as it did during the Little Ice Age.)
When a CME strikes a planet, the upper atmosphere is hit by a giant shotgun blast. Except a shotgun blast goes around 300 meters per second, 10,000 times slower than a CME. So, per unit of mass, the kinetic energy of a powerful CME is at least ten billion times more powerful than a shotgun blast. Since the liberation speed is going to be around ten kilometers per second, on an average life supporting planet, to be hit by projectiles going at 3,000 kilometers per second is going to knock all too much of the upper air atoms into space. That’s how Mars lost most of its atmosphere. And thus its ocean and much of its greenhouse. So now Mars is desperately airless, dry, and cold.
(More on the Serpens constellation here. Ed.)
Both Mars and Venus are at the limit of the inhabitable zone. But Venus does not have a magnetic field worth this name. Thus Venus lost a lot of its hydrogen (hence water; the rest is tied up in sulfuric acid, H2SO4).
It is known that the Earth’s strong magnetic field originates from the motion of huge masses of liquid metal within.
So a solar wind shield, a magnetosphere, is tied to the plate tectonic of a very dynamical planet with a powerful nuclear reactor deep inside. Whereas Venus and Mars are tectonically inert, at least, most of the time; maybe they wake up every half a billion years or so, for a big eruption. If Mars and Venus had been very tectonically active planets, may be they would be teeming with life (but that depends upon the distribution of heavy radioactive nuclei in a gathering solar system, an unknown subject, obviously non trivial, since Earth got them, and not the other two).
In any case the Earth’s magnetic shield protects life from the worst abuse of the Sun, as it deflects most of the CMEs out and around (they sneak back meekly as Aurora Borealis).
Another factor in the stable environment Earth provides for life is the Moon. The Earth-Moon system divides its angular momentum, between each other and the orbital motion of the Moon. This prevents the Earth to lay its rotation axis on its side: such a wobbling could not be compensated by the rest of the system. So it does not happen.
Mars, though, not being so impaired, wobbles between 15 and 35 degrees (causing weird, pronounced super-seasonal variations).
In any case, everything indicates that extremely primitive life appears quickly. But complex life needs time, lots of time, to evolve. Animal life and intelligence needs even more time. However, what strikes me in the new solar systems discovered so far, is how alien and unstable they are (this is partly a bias of the present detection methods).
Many of these systems have huge Jupiter styles planets in low orbit around their stars. It’s pretty clear that they fell down there, destroying the entire inner system in their path.
Other notions threaten life; gamma ray explosions, supernovas, and simply passing next to another star, throwing a solar system into chaos, and some Jupiters down into a fatal spiral. Our Sun, though, is pretty much cruising far from any star, in a cosmic void right now, perhaps left by a supernova explosion. Maybe we have been lucky for 4 billion years.
COSMIC GRANDEUR VERSUS MONKEY BUSINESS:
Many a physicist, or cosmologist, talks about the beginning of time, and other various notions pertaining to the grandest imagined machinery of the universe, as if they had found God, and it was themselves they were looking for (as Obama would put it). They claim to know their garden, the universe, pretty well (having apparently being there, at the moment of creation).
Verily, what we know for sure is what we see in pictures, and that’s plenty:
Notions such as the “edge of the universe” are much less scientifically robust than some scientists claim. When some talk about the “First Three Minutes”, one can only laugh, even if countless Nobel Prizes in physics subscribe to the notion. Physics is relative, the search for glory, absolute. At least so do monkeys behave.
The concept of time in Quantum Mechanics and Relativity are in complete contradiction. One is absolute, the other relative. So nobody knows for sure what time is, and what is truly its relation to space (nor do we know what space is, much beyond the pretty pictures given by the telescopes). Speaking of the history of time is completely meaningless, except as poetry. Or scientific sounding poetry. Too many holes in the logic.
Even using standard science to buttress one’s reflection, the size of the universe could well be at least a 1,000 bigger than the 14 billion light year piece that we presently observe. In truth, we have literally no idea. Even when sticking to conventional theory, which predicts only one thing in that respect, namely that the universe is bigger than what we see (it predicts it by requiring it actually, see below).
Another thing is sure: it’s incredibly immense out there, and not just in physical size, but also in conceptual size. We know lower bounds for the universe in size and complexity, but have no idea whatsoever about the upper bounds. Dark Energy is a perfect example. Fifteen years ago, Dark Energy was unknown. Now it makes up 74% of the mass of the universe.
PRESENTING SCIENTIFIC PHILOSOPHY AS SCIENCE IS NOT WISE:
It is not a good thing when highly uncertain science is presented as certain, just as much as really true parts of science. It is not just immodest. It undermines, and threatens, science deeply.
Because presenting as certain what is not so is just a lie. But science is truth, and that is why society supports it.
To present as true what is not so ridiculizes the notion of certainty. When, ultimately, the ineluctable collapse of immodest pseudo-certainty occurs, all of science gets slashed with doubt. American witches can run as republican candidates for the US Senate on completely crazed platforms, mumbling about mice with human brains (this happened in the last USA election). Scientists ought not to make craziness respectable by leveraging it themselves. Crazy is crazy, especially when a scientist does it. It’s craziness squared.
Make no mistake: speculation is central to science and even more to philosophy. Just speculation ought to be labeled as such. When I talk about my own TOW theory, I do not present it as fact and certitude.
Most of recent (last 120 years) physics was totally unexpected. A lot of it is true, no doubt, in some sense. Some of it is completely false, too, most probably, in the most fundamental sense. The more fundamental science gets, the more it gets subjected to representations which can be misleading. Thus when some physiology or solid state physics gets established, it will not be shattered. Not so for Quantum Field Theory (most of which being an extrapolation over an energy domain where it has not been tested).
Science, like philosophy, is not just a body of knowledge, but also a method. Both have to use common sense as much as possible. Philosophy uses the external edge of knowledge, the first inklings, the first warnings, the smallest indices, the irreproducible experiments. Thus any scientist searching for really shattering new science will pass through the philosophical method, as a mandatory passage to greater certainty.
When science is proclaimed, it has to be certain. Science is truth in which one can have faith. A lot of the most glitzy cosmology comes short of that. (Thus the adventures of the alleged Big Bang should not be used as an argument to fund expensive accelerators: there are enough good reasons to fund them, not to use the bad ones!) The surest part of cosmology is actually its pretty pictures.
INFLATE OUR CLAIMS, IF THE OLD ONES DID NOT WORK OUT:
All of recent conventional cosmology’s biggest and noisiest concepts rest on something called the Inflaton Field. One could say that it is just as much a rabbit out of a hat as in the best circus acts. There is no justification for it, except to explain what we see: something very big, very homogeneous, apparently contradicting relativity. The universe in its entirity.
The mystery that Cosmic Inflation tries to explain was this: as new regions of the universe come into view (at the speed of light!), it is observed that the new regions are exactly as the region we already know; same aspect, same background temperature, etc. How did they know how to look the same? They could not have talked to each other! Light did not have time to go from one to the other!
According to standard Einsteinian relativity, our region, and those regions, some on the opposite side of the universe from each other, have no common history! (Those new regions which appear are NOT within our past light cone… To use relativity lingo.)
In the USSR, Einstein’s work was criticized in minutia, for ideological reasons (Note1). So the great astrophysicist Zeldovitch came up in 1965 with the idea of inflation (the discovery is attributed to Guth, 1980, in the USA, because the USA buried the USSR, and America is a super power blessed by God, as the resident of the White House reminds his flock every day).
Einstein’s Relativity speaks of the speed of light within space, but not of the speed of space (so to speak). Speed of light is limited within space, speed of space is not limited. So it was breezingly supposed space had inflated at a gigantic speed, before slowing down. So the new regions coming into view had a sort of common history, after all.
From a philosophical perspective, to invent an explanation to explain a specific effect is called an ad hoc hypothesis. It can be a correct way to advance science, if it has predictive power (But differently from the neutrino, or the W, or the Higgs, how do you check for it? Finding the Inflaton particle? The Inflaton is supposed to have given birth to most other particles). In the meantime, it provides some hand waving to explain away an otherwise obvious contradiction with Relativity.
But it is not enough that some of the best theories in physics are weird, with the logical consistency of gruyere.
The apparent discovery of Dark Matter and especially Dark Energy, have brought a new twist. Dark Energy is completely unexplainable.
Dark Energy attracted attention to the fact that Quantum field theory is both the most precise and the most false theory ever contemplated (QFT is off in its prediction of vacuum energy by a factor of ten to the power 120, or so, the greatest mistake in theory, in the entire history of hominids… it would make even baboons scream in dismay.)
Billions of galaxies can be seen when we look as far as we can see. Here is a tiny detail, as far as we can see, without using a gravitational lens. [NASA-ESA Hubble]. Baffling. We are going to need a bigger imagination.
It’s hard for me to escape the feeling that the universe is much older than what standard cosmology believes, as I look at these very ancient, but very diverse galaxies in a piece of sky (Note 2).
Dark energy was discovered when it was realized, in super novae studies, that the universe’s expansion was accelerating (so energy is injected).
A natural question, though is this: ”If, as it turned out, the expansion is accelerating now, maybe it was at standstill much earlier?” Then the universe, even the small piece we can see, would be older and bigger than we have imagined so far. Don’t be afraid of the simple questions. Einstein asked himself at 16 what would happen if he looked at a mirror when going at the speed of light (Note 1).
Time will tell, as long as astronomy gets massively funded. Astronomy (astrophysics, cosmology, etc.) is one of the fields of science where fabulous progress is certain if it gets funded enough (the breakthroughs it made and will make in basic technology, to design the new instruments are very useful to the rest of society too).
In any case, the national debt is secure: it has a long way to go, before it can fill up the entire universe…
Einstein’s views on space and time came under the label “Theory of Relativity”. That incorporated Lorentz’s work on the correct space-time transformation group compatible with Maxwell equations.
That is why looking at a mirror will not work, at the speed of light, if the conventional addition of speed used by Galileo was really true, because light could not catch up: light could not be seen at the speed of light (just as sound cannot be heard if one goes away from it at the speed of sound). So Galilean Relativity did not work (the first scientists who pointed that out were not Einstein, but Lorentz, Fitzgerald, and Poincare’, among others; Lorentz got the Nobel Prize for it).
Soviet scientists were irritated by the exaggeratedly sounding “Relativity” (since only Marx was absolute). They pointed out that the “Theory of General Relativity” should be called the “Theory of Gravitation”, and then they made more pointed critiques.
Ideology is important in science. The “multiverse” theory, a support of string theory, is a case in point. The multiverse ideology exists, because string theory has nothing to say about the measurement process, so it sweeps that inconvenient truth below an infinity of rugs. The multiverse cannot be fought scientifically, because it is not science. But it is philosophically grotesque, since it consists in claiming that all lies are true, somewhere else.
The oldest galaxy was detected by Europeans at the Very Large Telescope in the high Chilean desert, in 2004, using a galactic super cluster as a lens (giving the VLT an aperture between 40 and 80 meters), had a redshift of 10, with an apparent age of more than 13 billion years.
Note on the notes: What did Einstein do in Relativity? He used an axiomatic method, with two axioms only (Principle of modern Relativity and Constancy of Light Speed).
Both axioms had been proclaimed by Poincare’, as Einstein knew, but Poincare’ had not realized that, with these two axioms only, all the known formulas could be derived in a few pages, as Einstein did (after doing away with the “Ether”, the substance in which waves were supposed to be waving). Einstein said he was influenced by empiricist philosophy from Hume and Mach.
The final story has not been written yet: and if the waves made the space? (TOW.)
