Explaining Space Travel

Posted by in categories: asteroid/comet impacts, biological, defense, engineering, ethics, existential risks, finance, geopolitics, habitats, military, nuclear energy, nuclear weapons, space, transparency

I recently posted this on the only two other sites that will allow me to express my opinions;

I see the problem as one of self similarity; trying to go cheap being the downfall of all these schemes to work around human physiology.

When I first became interested in space travel several years ago I would comment on a couple blogs and find myself constantly arguing with private space proponents- and saying over and over again, “there is no cheap.” I was finally excommunicated from that bunch and banned from posting. They would start calling me an idiot and other insults and when I tried to return the favor the moderator would block my replies. The person who runs those two sites works for a firm promoting space tourism- go figure.

The problem is that while the aerospace industry made some money off the space program as an outgrowth of the military industrial complex, it soon became clear that spaceships are hard money- they have to work. The example of this is the outrage over the Apollo 1 fire and subsequent oversight of contractors- a practice which disappeared after Apollo and resulted in the Space Shuttle being such a poor design. A portion of the shuttle development money reportedly went under the table into the B-1 bomber program; how much we will never know. Swing wings are not easy to build which is why you do not see it anymore; cuts into profits.

…here’s Tom with the Weather.
That right there is comedian/philosopher Bill Hicks, sadly no longer with us. One imagines he would be pleased and completely unsurprised to learn that serious scientific minds are considering and actually finding support for the theory that our reality could be a kind of simulation. That means, for example, a string of daisy-chained IBM Super-Deep-Blue Gene Quantum Watson computers from 2042 could be running a History of the Universe program, and depending on your solipsistic preferences, either you are or we are the character(s).

It’s been in the news a lot of late, but — no way, right?

Because dude, I’m totally real
Despite being utterly unable to even begin thinking about how to consider what real even means, the everyday average rational person would probably assign this to the sovereign realm of unemployable philosophy majors or under the Whatever, Who Cares? or Oh, That’s Interesting I Gotta Go Now! categories. Okay fine, but on the other side of the intellectual coin, vis-à-vis recent technological advancement, of late it’s actually being seriously considered by serious people using big words they’ve learned at endless college whilst collecting letters after their names and doin’ research and writin’ and gettin’ association memberships and such.

So… why now?

Want to Get 70 Billion Copies of Your Book In Print? Print It In DNA

Posted by in categories: biological, biotech/medical, chemistry, futurism, information science, media & arts

I have been meaning to read a book coming out soon called Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves. It’s written by Harvard biologist George Church and science writer Ed Regis. Church is doing stunning work on a number of fronts, from creating synthetic microbes to sequencing human genomes, so I definitely am interested in what he has to say. I don’t know how many other people will be, so I have no idea how well the book will do. But in a tour de force of biochemical publishing, he has created 70 billion copies. Instead of paper and ink, or pdf’s and pixels, he’s used DNA.

Much as pdf’s are built on a digital system of 1s and 0s, DNA is a string of nucleotides, which can be one of four different types. Church and his colleagues turned his whole book–including illustrations–into a 5.27 MB file–which they then translated into a sequence of DNA. They stored the DNA on a chip and then sequenced it to read the text. The book is broken up into little chunks of DNA, each of which has a portion of the book itself as well as an address to indicate where it should go. They recovered the book with only 10 wrong bits out of 5.27 million. Using standard DNA-copying methods, they duplicated the DNA into 70 billion copies.

Scientists have stored little pieces of information in DNA before, but Church’s book is about 1,000 times bigger. I doubt anyone would buy a DNA edition of Regenesis on Amazon, since they’d need some expensive equipment and a lot of time to translate it into a format our brains can comprehend. But the costs are crashing, and DNA is a far more stable medium than that hard drive on your desk that you’re waiting to die. In fact, Regenesis could endure for centuries in its genetic form. Perhaps librarians of the future will need to get a degree in biology…

Evolution in a Toxic World

Posted by in categories: biological, evolution

Earth is a hostile place — and that’s even before one starts attending school. Even when life first sparked into being, it had to evolve defenses to deal with a number of toxins, such as damaging ultraviolet light, then there were toxic elements ranging from iron to oxygen to overcome, later, there was DDT and other toxic chemicals and of course, there are all those dreaded cancers.

In Evolution In A Toxic World: How Life Responds To Chemical Threats [Island Press; 2012: Guardian Bookshop; Amazon UK;Amazon US], environmental toxicologist Emily Monosson outlines three billion years of evolution designed to withstand the hardships of living on this deadly planet, giving rise to processes ranging from excretion, transformation or stowing harmful substances. The subtitle erroneously suggests these toxins are only chemical in nature, but the author actually discusses more than this one subclass of toxins.

The method that arose to deal with these toxins is a plethora of specialised, targeted proteins — enzymes that capture toxins and repair their damages. By following the origin and progression of these shared enzymes that evolved to deal with specific toxins, the author traces their history from the first bacteria-like organisms to modern humans. Comparing the new field evolutionary toxicology to biomedical research, Dr Monosson notes: “In light of evolution, biomedical researchers are now asking questions that might seem antithetical to medicine”.

The Social Sciences Revolution

Posted by in categories: biological, complex systems, economics, geopolitics, philosophy, policy

Scientific discovery in the natural sciences has proceeded at an exponential rate and we are now seeing the social sciences experience a profound transformation as a consequence of computational social science. How far computational social science will reinvent social science is the big question. Some of the themes I’ve explored in my own work have been about the relationship between political philosophy and science and whether the computational sciences can help formulate new conceptions of societal organisation. Many in the field seem to think so.

These three things—a biological hurricane, computational social science, and the rediscovery of experimentation—are going to change the social sciences in the 21st century. With that change will come, in my judgment, a variety of discoveries and opportunities that offer tremendous prospect for improving the human condition. It’s one thing to say that the way in which we study our object of inquiry, namely humans, is undergoing profound change, as I think it is. The social sciences are indeed changing. But the next question is: is the object of inquiry also undergoing profound change? It’s not just how we study it that’s changing, which it is. The question is: is the thing itself, our humanity, also changing? (Nicholas A. Christakis, A NEW KIND OF SOCIAL SCIENCE FOR THE 21st CENTURY)

A biological understanding of human nature combined with new insights derived from computational social science can potentially revolutionise political, social and economic systems. Consequently there are profound philosophical implications. Secular political philosophy specifically emerged out of the European experience of Church and monarchical rule, and socialism emerged out of the experience of industrialisation and capitalist ideology. Therefore is it possible that a new political philosophy could emerge out of the reinvention of the social sciences?

One question that fascinated me in the last two years is, can we ever use data to control systems? Could we go as far as, not only describe and quantify and mathematically formulate and perhaps predict the behavior of a system, but could you use this knowledge to be able to control a complex system, to control a social system, to control an economic system? (Albert-lászló Barabási, THINKING IN NETWORK TERMS)

The Propagation of Life: Infecting other Worlds

Posted by in categories: biological, ethics, evolution, existential risks, habitats

It is with great bewilderment that I read the precautions that NASA rovers are sterilized to, to ensure that Life does not infect the Martian environment. I understand NASA want to explore Mars for signs of Martian life — but which is more important — to explore whether Life almost evolved on Mars, or to induce the whole process and allow it to occur?

We can get caught up in the concept that preservation of Human Life as the ultimate goal, in how do we colonize other worlds as soon as possible — but perhaps the most honorable pursuit is the propagation of Life itself — we should be introducing bacteria or simple xerophytic plants to Mars, algae to Europa and such worlds, in the anticipation that if a foothold can be taken, evolution could take hold — and we may not live to see it — but we have then passed on the gift of life to another world.

Whimsical Notions or Planning With Foresight? Unless we cause our own demise by inadvertently engineering our downfall, as often discussed here, or are struck by a statistically unfortunate large asteroid impact, Life is here on Earth for the long haul — it has been durable for billions of years, albeit with significant setbacks, and one can expect it will be here for billions more to come. We may well have time on our hands.

If we sow the seeds now, we may have other worlds to move to in a few million years — long before we may need it — such as in five billion years when the Sun has expired into a Red Giant. It is quite reasonable to expect that if we seed Mars with our bacteria now, and other basic forms of life at the bottom of the food chain — in some million years from now Mars may be flourishing with vegetation — evolved to suit the terrain — that a colony there could live off.

It has been considered, that Life on Earth started by a similar process, that a comet or asteroid carrying bacteria inseminated our planet with the seeds of life. So let’s pass on the gift and stop being so prudent. Lets start at the basics, and create lifeboats of Life around our solar system. Perhaps one day our descendants will thank us for nurturing such habitats.

GENCODE Apocalypse

It is a race against time- will this knowledge save us or destroy us? Genetic modification may eventually reverse aging and bring about a new age but it is more likely the end of the world is coming.

The Fermi Paradox informs us that intelligent life may not be intelligent enough to keep from destroying itself. Nothing will destroy us faster or more certainly than an engineered pathogen (except possibly an asteroid or comet impact). The only answer to this threat is an off world survival colony. Ceres would be perfect.

Christian Astronomers

“The more anxiety one produces, the more the discussion there would be about how real and how possible actual existential threats are.”

John Hunt recently queried me on what steps I might take to form an organization to advocate for survival colonies and planetary defense. His comment on anxiety is quite succinct. In truth the landing on the moon was the product of fear- of the former Soviet Union’s lead in rocket technology. As we as a nation quelled that anxiety the budget for human space flight dwindled. But the fear of a nuclear winter continued to grow along with the size of our arsenals.

Interestingly, at the height of the cold war, evidence of yet another threat to human existence was uncovered in the Yucatan peninsula of Mexico in 1981; Chicxulub. But even before the dinosaur killer was discovered, perhaps the greatest threat of all to humanity was born in 1973 when Herb Boyer and Stanley Cohen created the first genetically modified organism. The money to answer both of these threats by going into space continues to be expended by the military industrial complex.

Mile wide rocks in space and microscopic organisms on earth are both threats to our existence, but the third and undoubtedly greatest threat is our own apathy. Why do we expend the tremendous resources of our race on everything BUT keeping it from going extinct?

The Truth about Space Travel is Stranger than Fiction

Posted by in categories: asteroid/comet impacts, biological, biotech/medical, business, chemistry, climatology, complex systems, cosmology, counterterrorism, defense, economics, education, engineering, ethics, events, evolution, existential risks, finance, futurism, geopolitics, habitats, homo sapiens, human trajectories, life extension, lifeboat, media & arts, military, neuroscience, nuclear weapons, physics, policy, space, sustainability, transparency, treaties

I have been corresponding with John Hunt and have decided that perhaps it is time to start moving toward forming a group that can accomplish something.

The recent death of Neil Armstrong has people thinking about space. The explosion of a meteor over Britain and the curiosity rover on Mars are also in the news. But there is really nothing new under the sun. There is nothing that will hold people’s attention for very long outside of their own immediate comfort and basic needs. Money is the central idea of our civilization and everything else is soon forgotten. But this idea of money as the center of all activity is a death sentence. Human beings die and species eventually become extinct just as worlds and suns also are destroyed or burn out. Each of us is in the position of a circus freak on death row. Bizarre, self centered, doomed; a cosmic joke. Of all the creatures on this planet, we are the freaks the other creatures would come to mock- if they were like us. If they were supposedly intelligent like us. But are we actually the intelligent ones? The argument can be made that we lack a necessary characteristic to be considered truly intelligent life forms.

Truly intelligent creatures would be struggling with three problems if they found themselves in our situation as human beings on Earth in the first decades of this 21st century;

1. Mortality. With technology possible to delay death and eventually reverse the aging process, intelligent beings would be directing the balance of planetary resources towards conquering “natural” death.

How to Build a Spaceship again

Posted by in categories: asteroid/comet impacts, biological, biotech/medical, business, chemistry, counterterrorism, defense, economics, education, engineering, ethics, events, existential risks, finance, futurism, geopolitics, habitats, human trajectories, life extension, lifeboat, media & arts, military, nuclear weapons, physics, policy, space, sustainability, transparency

This essay was originally posted last year and is now back with small changes. Enjoy.

The first decade of the 21st century ended with human space flight nowhere near to fulfilling the predictions made at the beginning of the space age. Not even close. Just as the Vietnam war robbed the space exploration budget, the end of the century found vast public funds, a truly mind boggling amount of treasure, spent on the cold war toys that have yielded guaranteed huge profits for the military industrial complex. Many of these incredibly expensive weapon systems do not work as advertised and very few of them have any application in the present war on terror. 911 did not stop the money flowing to new super fighter planes and missiles designed to shoot down other missiles. The promise of space was in truth sacrificed for the profits of the weapons industry. The expected moon bases and colonies on Mars were never funded and no human being has escaped earth orbit since the last Apollo mission. The underfunded space shuttle completely failed to provide the cheap lift and multi-mission capability that was never really possible to achieve. The showpiece International Space Station is little more than a 100 billion dollar collection of tin cans flying in endless circles.

Over a quarter century wasted and the human race seems in large part to have accepted the end of the space age. Despite a collection of old and new inferior lift vehicles incapable of accelerating a spacecraft to escape velocity, there is endless hype concerning the privatization of space and the bright future these for profit enterprises will bring about. The single point of failure in these schemes is the false miracle of fuel depots in space. These orbital gas stations will supposedly enable all the missions that previously could only be accomplished by a Heavy Lift Vehicles like the Saturn V. Cryo fuel storage and transfer is at this time a myth and has never even been attempted due to the extreme difficulties involved. It is simply a smoke screen to disguise defeat. We are not going anywhere if we stay on this path. The only hope for human space flight is the realization that deep space travel may at any time mean the difference between humankind surviving or disappearing forever. If this truth cannot unlock the vast resources required then we are sealing our collective fate. The Spaceship is the only insurance against extinction. Safeguarding the entire human race is the ultimate military mission, yet is completely ignored by our leaders and the defense industry. The inevitable asteroid or comet impact and the threat of a 100 percent lethal plague are with us right now. We as a species are playing a game of Russian roulette. We truly do not know when, but we know what is coming.

Everyone breathes a sigh of relief when it is explained that disastrous impacts only occur an average of once every several million years. The key fact never discussed is impacts are random. An impact could occur tomorrow, and again the next day, and it would just be a blip on a curved line representing the immensity of geologic time. No one would be left to exclaim, “WOW! What were the odds of that happening?” In the same way the threat of engineered pathogens is ignored, overlooked, or scoffed at in the hopes it will just go away. Just as there is little than can be done to stop seasonal flu, there is very little that could be done to stop such an airborne plague once it begins. Naturally evolved pathogens always leave a certain percentage of survivors but an engineered virus does not follow that rule. We are led to believe there is no defense, but we are being decieved and there is nothing further from the truth.
